How Long Reheat Pizza in Microwave? Easy & Quick Guide

ByMeghan Splawn

Introduction

Leftover pizza is one of those rare foods that can be just as comforting the next day as it was fresh out of the box. The only issue is that reheating it properly can be tricky. If done the wrong way, it can go from a crispy slice to a rubbery, soggy, or unevenly hot disappointment in a matter of seconds. For most people, the quickest option on hand is the microwave, which leads to the very common question: How Long Reheat Pizza in Microwave?

The answer depends on a few key factors, such as the thickness of the crust, the number of slices, the toppings, the wattage of your microwave, and the method you use to help balance moisture and heat. While the microwave will never perfectly recreate the crispness of a fresh slice from a hot oven, there are tried and tested ways to get a slice that is hot all the way through with far less chewiness than the most common rushed approach.

This guide is built to walk through every detail you need to know. From timing by slice count and crust type, to tools that actually make a difference, to the most common mistakes to avoid, everything here is focused on practical steps you can use right now with the equipment you likely already have. By the end, you will know exactly how to approach reheating pizza in the microwave with realistic expectations and reliable results.

Why Microwaving Pizza Is Tricky

To understand the correct timing for How Long Reheat Pizza in Microwave? it helps to know what is happening at a science level. Microwaves work by exciting water molecules with electromagnetic waves. This causes those molecules to vibrate rapidly, which generates heat from within the food rather than from a hot surface.

Pizza has a unique makeup that makes this both convenient and problematic. The crust is mostly dry starch with little internal moisture, the sauce holds a decent amount of water, the cheese is a blend of fats and proteins that can melt very quickly, and many toppings add their own moisture or fat. When all of these are heated at the same rate from the inside out, the water in the sauce and toppings turns to steam. That steam has nowhere to go and soaks into the already porous crust, leading to a limp, soggy base.

At the same time, the edges of the slice can heat far faster than the thicker center or any dense toppings. The cheese can become molten and stretchy one second, then go greasy and rubbery the next if overheated. This is exactly why blindly adding a minute or more at full power is the most common reason for a disappointing result.

The goal is not to eliminate this entirely, but to limit excess steam, spread heat more evenly, and use short heating bursts with just enough time to bring the slice to a hot, safe temperature without overcooking the cheese or turning the crust to mush.

Key Factors That Affect Reheating Time

There is no single number that fits every slice. Before settling on a time, take a moment to consider the factors below. Adjusting for these is far more reliable than following a guess.

Microwave Wattage

Microwaves are rated by wattage, with most common models falling between 700 and 1100 watts. A higher wattage unit will reheat much faster, while a lower wattage unit will need extra time in smaller increments. If you do not know your wattage, it is safe to start on the lower end of the suggested times and add in 10 to 15 second bursts until hot.

Crust Thickness

Thin crust slices have less mass and less internal structure to protect, so they heat very quickly and are more prone to going limp. Medium crusts sit in the middle. Thick crust, pan style, or deep dish slices have a much denser base and often hold more sauce and cheese, meaning they need more time to heat the center without scorching the very top layer.

Number of Slices

Reheating one slice is very different from reheating two or three at once. The more cold food in the microwave, the more energy is needed to raise the overall temperature. For more than one slice, increase time gradually rather than doubling it outright, as hot spots can become much more uneven.

Toppings

Plain cheese slices tend to reheat the most evenly. Heavier toppings such as pepperoni, sausage, onions, peppers, or extra cheese add density and can create cold spots. Very oily toppings can also make the crust feel greasier if overheated. Slices loaded with vegetables may release extra moisture and benefit even more from a moisture balancing trick.

Starting Temperature

Pizza straight from a cold refrigerator will take longer than pizza that has sat out for a short time, though for food safety reasons it is always best to limit how long leftovers sit at room temperature. For the sake of timing alone, fully chilled slices need a little more patience and shorter bursts to avoid overheating the outside.

Pizza Shape and Size

A standard triangular slice with a wide crust edge and a narrower tip heats unevenly by nature. The wider, thicker crust end tends to lag behind the thin tip which can become very hot. New York style, Neapolitan style, Sicilian, or square cut slices all behave slightly differently and should be judged by their actual thickness rather than by name alone.

Tools You May Want to Use

You do not need any specialty gear to reheat pizza in a microwave, but a couple of simple items can drastically improve the outcome. Using at least one of the below is highly recommended if texture matters to you.

Microwave Safe Plate

Always use a flat, microwave safe plate. Avoid metal pans or anything not rated for microwave use. A smooth ceramic or glass plate works well and conducts heat evenly enough to pair with the tricks below.

Paper Towel

A dry paper towel placed loosely under the slice helps absorb a small amount of excess moisture that would otherwise soak into the crust. For very saucy slices, this is one of the cheapest and most effective small improvements.

Cup of Water Method

One of the most widely used tricks is to place a small, microwave safe cup of water next to the pizza slice in the microwave. The water absorbs some of the excess microwave energy and creates a gentler heating environment. The result is less aggressive drying in some spots and often less rubbery cheese when done in short bursts. (See Also:Can You Microwave Frozen Mozzarella Sticks)

Microwave Crisping Tray

Some households have a microwave crisping tray or crisper pan designed to heat from below. If you have one, follow its instructions closely. These can help the bottom of the crust stay a little firmer compared to a bare plate, though results still vary by model.

For most people, a paper towel plus a small cup of water is more than enough and uses items already in the kitchen.

How Long Reheat Pizza in Microwave? By Slice Count, Crust, and Wattage

Use this table as your baseline. These are realistic ranges for a standard microwave. Always start at the lower time and add in short bursts. This is the safest and most consistent way to answer How Long Reheat Pizza in Microwave? without overdoing it.

Slice Count Crust Type 700-800 Watt 900-950 Watt 1000-1100 Watt Notes
1 slice Thin crust 40 – 55 seconds 30 – 40 seconds 25 – 35 seconds Very prone to going limp. Use paper towel. Heat in 10-15 second bursts at the end.
1 slice Medium crust 55 – 70 seconds 40 – 55 seconds 35 – 45 seconds Most forgiving. Check center before adding more time.
1 slice Thick crust / Pan 70 – 85 seconds 55 – 70 seconds 45 – 60 seconds Needs time for center. Use short bursts to avoid melting cheese too aggressively.
1 slice Deep dish 85 – 95 seconds 70 – 80 seconds 60 – 70 seconds Dense. Focus on heating the very center. Add in 10-15 second bursts after initial time.
2 slices Thin crust 65 – 80 seconds 50 – 60 seconds 40 – 50 seconds Leave a small gap between slices if possible. Rotate halfway if your microwave lacks a turntable.
2 slices Medium crust 80 – 90 seconds 60 – 75 seconds 50 – 65 seconds Test both slices. The one closer to the edge can heat faster.
2 slices Thick crust / Pan 95 – 110 seconds 75 – 90 seconds 65 – 80 seconds Often needs bursts. Check middle of each slice for warmth.
3 slices Medium crust 95 – 110 seconds 80 – 95 seconds 70 – 85 seconds Best in short bursts of 15-20 seconds after the first round to avoid hot spots.
3 slices Thick crust / Pan 110 – 125 seconds 95 – 110 seconds 80 – 95 seconds Prioritize checking the thickest slice’s center above all else.

These numbers are meant to be a guide, not a rule carved in stone. If your slice is unusually saucy, heavily topped, or from a very thick pan, lean towards the lower end and build up. If it came straight from the coldest part of your fridge and is especially dense, use the middle to upper end but strictly in bursts.

Step-By-Step Guide To Reheat Pizza In Microwave

For the most reliable balance of speed and texture, follow these steps in order. This method uses the paper towel and small cup of water approach which is accessible for nearly everyone.

  1. Inspect the slices. Look at the crust thickness and how much sauce or toppings are on each slice. If you are reheating different slices with very different thicknesses, it is often better to reheat them separately for more even results.
  2. Prep your plate. Place a flat, microwave safe plate down. Lay a clean, dry paper towel across the plate, large enough to sit under the slice without folding up over the toppings.
  3. Arrange the pizza. Set your slice onto the paper towel with the crust edge touching the plate. If reheating more than one slice, leave at least a small gap between them to allow a bit more airflow and reduce clumping of heat.
  4. Add a moisture buffer. Take a small microwave safe cup or mug and fill it with about half a cup of room temperature water. Place it in the microwave alongside the plate, not on top of the pizza. Try to keep it away from directly touching the slice.
  5. Start with a conservative time. Using the table above, pick the time for your wattage, slice count, and crust. Start at the lowest suggested value for that combination. Do not start at the maximum.
  6. Heat in bursts. Run the microwave for your starting time. Carefully check the slice by touching the thickest part of the crust and the very center of the toppings with a clean fingertip. If it is still cool in the center, heat for another 10 to 15 seconds at a time, checking after each burst.
  7. Check for even heat. Pay extra attention to the thin tip, the wide crust end, and any dense pile of toppings. These are almost always the three spots that differ the most. Rotate the plate a quarter turn if your microwave does not have a functioning turntable.
  8. Rest briefly. Remove the plate and cup of water carefully, as they can be hot. Let the slice rest for 30 to 60 seconds before eating. This short rest allows residual heat to spread from the hotter outer areas into any lingering cooler spots and helps the cheese settle slightly.
  9. Test and adjust. Take a small bite from the center. If it is hot all the way through with no lukewarm core, you are done. If not, repeat with 10 second bursts until it reaches an evenly hot temperature.

The key throughout this process is restraint. Adding five extra bursts of ten seconds will almost always beat adding sixty seconds all at once when learning How Long Reheat Pizza in Microwave? for your exact setup.

Microwave Vs Other Methods: A Practical Comparison

The microwave is not the only way to reheat pizza, but it is by far the fastest. It is worth knowing the tradeoffs so you can pick the right method for the situation you are in.

Method Approximate Time Crust Texture Even Heating Convenience Best For
Microwave (with paper towel + water cup) 25 – 95 seconds Soft with slightly firmer base compared to bare microwave Decent with bursts and rotation Highest. Minimal setup and fastest overall. Quick lunch, late night, or when you only need one or two slices hot now.
Skillet on stovetop 4 – 7 minutes total Noticeably crisper bottom, pleasantly chewy Good if covered briefly Medium. Needs a pan, a lid, and attention. When you care most about a firmer, less soggy crust.
Oven / Toaster Oven 6 – 10 minutes Closest to near fresh, crisp edges and base Very even for multiple slices Lower for a small amount. Needs preheat time. Reheating several slices or when texture is the top priority.
Air Fryer 2 – 4 minutes Very crisp bottom and edges Generally even with space between slices Medium. Fast but limited by basket size. Great middle ground if you want crispness without heating a full oven.

For pure speed, nothing beats the microwave. With the method above, it is realistic to get a hot slice in under a minute while avoiding the worst of the sogginess that gives it a bad reputation.

Tips and Best Practices

These practical tips are easy to apply and will make a noticeable difference without adding much effort.

  • Start low every time. Treat the table times as a ceiling to approach, not a starting point to hit. Bursts are your best tool.
  • Mind the tip. The pointed tip of a triangular slice is the thinnest part and will be the first to go scalding hot. Blow on it or check it separately before taking a full bite.
  • Separate different pizzas. If slices are from different styles or have wildly different toppings, reheat separately. They will not finish at the same time.
  • Use a dry paper towel. Replace the paper towel if it becomes very damp between rounds, though for one or two slices it is usually fine as is.
  • Keep the water cup simple. A small cup of plain water is all you need. Do not seal it, do not add anything to it, and make sure it is fully microwave safe.
  • Rotate for uneven units. If your microwave has no turntable or runs unevenly, rotate the plate 90 degrees after the first burst.
  • Prioritize the center. A slice can feel hot around the crust and cheese edges but still be lukewarm right in the middle of a thick topping patch. Always test the center.
  • Go easier on extra cheese. Slices with a very thick layer of cheese melt extremely fast. Drop time slightly and rely more on short bursts.
  • Don’t stack. Never stack slices on top of each other to save space. They will steam each other and heat very unevenly.
  • Rest for texture. That 30 to 60 second rest is small, but it takes the edge off extreme hot spots and feels less harsh to eat.

Common Mistakes To Avoid

Most bad results come from a handful of repeat mistakes. Avoiding these will instantly improve your outcome when figuring out How Long Reheat Pizza in Microwave?

  • Heating for a full minute blindly. Starting at 60 seconds for a thin slice is almost guaranteed to make it rubbery. Always scale down first.
  • Skipping any form of moisture control. Putting a bare slice straight onto a cold plate with no paper towel is the most common route to a soggy, steamed base.
  • Overusing full power. Most of the time, full power is fine with bursts, but jumping straight to the longest time on full power is the issue. The fix is duration, not dropping power for the sake of it in most home units.
  • Ignoring wattage. Copying a time from a much higher wattage unit will wreck a lower wattage microwave and vice versa.
  • Reheating too many at once. Cramming three or four slices side by side often leaves some ice cold and others boiling. If you must do more than two, do in rounds or accept more frequent bursts.
  • Eating immediately from hot spots. Molten cheese can hold heat extremely well. The rest after heating prevents the most unpleasant burns.
  • Microwaving frozen pizza this way. This guide is for fully refrigerated leftover pizza. Frozen slices need a different approach entirely and should follow their specific directions or be thawed with care.
  • Using a sealed container. Never cover pizza with an airtight lid in the microwave. Trapped steam will make the crust far worse than leaving it open with just a paper towel underneath.
  • Forgetting the center test. Judging by the crust alone is misleading. The center is almost always the last thing to reach a safe, satisfying temperature.

Troubleshooting Uneven Or Unsatisfying Results

Even with care, things can go sideways depending on your exact pizza. Use this quick troubleshooting to correct course.

Crust Is Too Soggy

If the base is limp right after heating, the main culprit is trapped steam. Make sure you are using a dry paper towel underneath, leave the top uncovered, avoid stacking, and try the cup of water method. For your next attempt, drop the time by 10 to 15 seconds and rely more on bursts. Very saucy slices benefit the most from these changes.

Cheese Is Rubbery Or Greasy

Rubbery cheese usually means it went too hot for too long. Greasy cheese often means the oils separated from overheating. The fix is shorter bursts, starting lower, and pulling it a second or two before you think it is perfectly done. The short rest will still bring up the overall temperature without pushing the cheese past its melting point.

Cold Center With Hot Edges

This is the classic microwave issue. Spread heat by using shorter bursts, rotate the plate, and avoid one long heating cycle. For thicker slices, increase by 10 second bursts rather than 20 or 30. The cup of water method also takes the edge off the aggressive edge heating that causes this split.

Tip Is Scorching While Crust End Is Lukewarm

This comes down to shape. After a round of heating, if the narrow tip is already very hot, you can either rotate the slice so the tip points towards the center of the turntable less directly, or simply cut your burst size down to 5 to 10 seconds. Testing in stages is far easier than trying to fix this after the fact.

Still Chewy But Not Melty

If the cheese looks set but tight and the slice feels oddly chewy without being soft and hot, you likely underheated the dense areas. Add very small bursts, focusing on the center and any thick topping clusters. Give it the full 30 to 60 second rest before judging again, as residual heat can finish the job more gently.

Reheating Special Pizza Types

Not all pizzas behave the same. Use these adjustments alongside the general guide for the most realistic results. (See Also:Can You Put Bentgo In Microwave)

Thin Crust

Thin crust is the fastest to heat and the easiest to ruin. Use the lowest times from the table, always with a paper towel, and stick to 10 second bursts. One minute is often more than enough for a single thin slice at 1000 watts. Watch it constantly once it starts looking glossy.

New York Style

New York style usually sits between thin and medium. The wide, foldable slice has a thinner middle and a slightly bolder outer crust. Reheat one slice at a time, check the fold area which can trap heat, and favor bursts over long runs.

Pan Style Or Sicilian

These have a thicker, more bread like base that absorbs less steam in some spots but takes longer to warm through. They often need a little more time, but only increase gradually. The bottom can stay soft in the microwave, so don’t expect a deep fried crispness. Focus on getting the center piping hot without liquifying the cheese layer.

Deep Dish

Deep dish is the most time consuming for the microwave. Prioritize heating the very center, as the outer edge can look done while the middle is still cold. Use the longer range from the table, work strictly in 10 to 15 second bursts after the first round, and allow the full rest time. For very tall slices, this patience is necessary.

Extra Saucy Or Loaded

Heavy sauce means more water to turn to steam. Extra meat or dense veggie toppings mean more cold mass. Use a dry paper towel, consider leaving a little extra gap if doing two slices, and lean towards the lower time with more bursts. These are the types that benefit the most from the cup of water method.

White Pizza Or Pizza With Delicate Toppings

Pizzas without a red sauce can sometimes heat a little differently, but timing is usually similar to cheese pizza of the same crust. If there are very delicate toppings that don’t need much heat, err on the side of less time and let the base and cheese carry the rest during the short rest.

Food Safety Notes For Leftover Pizza

Speed and texture matter, but food safety should always come first. Keep these points in mind when reheating any leftovers.

  • Refrigerate promptly. Leftover pizza should be placed in the fridge within a reasonable time after eating. The less time spent at room temperature, the better.
  • Only reheat what you plan to eat. Repeatedly reheating and cooling leftovers increases unnecessary risk. Take out just the slices you intend to eat at that moment.
  • Heat to a safe temperature. Aim for the food to be hot throughout, especially the center. While exact numbers can vary by guidance, uneven cold spots are the thing to watch for the most. Use your test from the center, not just the crust.
  • Inspect before reheating. If the pizza has an off smell, slimy feel, unusual discoloration, or has been stored for an excessive amount of time, do not reheat or eat it. When in doubt, discard it.
  • Be careful with hot plates and cups. Both the plate and the small cup of water can be much hotter than expected after microwaving. Handle with care to avoid burns.
  • Mind young or sensitive eaters. Molten cheese holds heat for a while. Always test temperature before serving to others.

Frequently Asked Questions

How long to reheat pizza in microwave for 1 slice?

For one slice, it is usually between 25 and 60 seconds depending on crust thickness and wattage. For a thin crust at 1000-1100 watts, start around 25 to 35 seconds. For a medium crust at 900-950 watts, start around 40 to 50 seconds. For a thick crust, start around 50 to 60 seconds. Always begin at the lower end and use 10 to 15 second bursts until the center is hot.

Is it better to put a cup of water in the microwave with pizza?

In most home microwaves, yes. Placing a small, microwave safe cup of about half a cup of water next to the slice helps take the edge off the overly aggressive heating. This often leads to less rubbery cheese and can reduce some of the extreme dryness that makes reheated pizza harsh. It is not required, but it is one of the simplest ways to improve results when answering How Long Reheat Pizza in Microwave?

Should I put a paper towel under pizza in the microwave?

Yes. A dry paper towel under the slice helps absorb excess moisture released as steam. This is especially helpful for thin crust and very saucy slices. Make sure it is only under the base and not covering the toppings.

How long to reheat 2 slices of pizza in the microwave?

For two slices, expect roughly 40 to 80 seconds at most common wattages. Thin crust often falls around 40 to 60 seconds total, medium around 50 to 75 seconds, and thick crust around 65 to 80 seconds. Leave space between them, rotate if needed, and use bursts near the end to even things out.

Why does microwave pizza get rubbery?

Rubbery cheese is usually caused by overheating. Microwaves heat very quickly and cheese proteins tighten when pushed too far. Using shorter heating times, starting low, relying on bursts, adding a small cup of water, and allowing a short rest all help prevent this. (See Also:Can You Heat Up Brie In Microwave)

Can I make microwave reheated pizza less soggy?

Yes. Use a dry paper towel under the slice, leave it uncovered, avoid stacking, don’t use an airtight cover, and don’t overheat. The cup of water method also helps by reducing the intensity of the heating cycle. For thin and saucy slices, dropping time by a few seconds and extending with bursts is often the turning point.

Do I need to adjust for a low wattage microwave?

Absolutely. A 700 watt microwave can need nearly double the burst count compared to a 1100 watt unit. If your microwave is on the lower end, ignore any very short times you may see elsewhere and use the 700-800 watt column from the table as your starting point. Test in 15 second bursts to be safe.

Should I cover pizza in the microwave when reheating?

No, it is better to leave it uncovered. Covering traps steam directly against the crust and almost always makes it softer and more soggy. The only thing you want underneath is a dry paper towel, not a lid.

Is it safe to reheat pizza more than once?

It is not recommended. Each time food cools and reheats, there are more opportunities for temperature issues. For both safety and quality, only reheat the exact amount you plan to eat in one go.

How can I tell when reheated pizza is ready in the microwave?

Look for melted cheese with no stiff, dry patches, and test the center with a clean fingertip or the tip of a fork. The center should feel hot all the way through with no obvious cool spot. The crust may still be soft, but it should not feel ice cold in the middle. After resting for 30 to 60 seconds, it should feel evenly hot overall.

Conclusion

The fastest way to bring leftover pizza back to life is knowing exactly How Long Reheat Pizza in Microwave? for your slice. There is no magic number for every box, but by factoring in crust thickness, slice count, and your microwave wattage, you can land in the right range every time.

For most people, the winning formula is simple: use a dry paper towel under the slice, place a small cup of water beside it, start at the lowest time from the guide, heat in short 10 to 15 second bursts, and give it a 30 to 60 second rest before eating. This takes barely any extra effort, yet it makes a huge difference in avoiding the rubbery cheese and soggy crust that give microwaved pizza its reputation.
