How Long Do I Microwave Pizza? The Short Answer
For one average leftover slice in a typical microwave, start with 30 to 45 seconds on high power. If the slice is cold from the refrigerator, very thick, or heavily topped, it may need 45 to 60 seconds. Frozen pizza slices or mini pizzas often take 1 to 3 minutes, depending on size and wattage. Whole frozen pizzas usually follow package directions and may take 4 to 8 minutes or more, often with a crisping tray or special microwave instructions.
The safest approach is to heat in short intervals rather than guessing one long time. Microwave energy can create hot spots, so a slice may look fine on top while the center is still cold. After the first interval, check the pizza, rotate it if needed, and add 10 to 15 seconds at a time. This prevents overheating, which can make cheese tough and crust chewy.
When asking How Long Do I Microwave Pizza?, remember that the best answer is a range, not one exact number. A thin New York-style slice in a powerful microwave may be ready in 25 seconds, while a deep-dish slice in a lower-wattage microwave may need closer to a minute. Use the table later in this guide as a starting point, then adjust based on your microwave and pizza.
Microwave Wattage Matters
Microwave wattage is the most important variable when estimating reheating time. A 1200-watt microwave heats much faster than a 700-watt microwave. Many compact dorm, office, or older microwaves operate at lower wattage, while larger kitchen models often range from 900 to 1200 watts. If you do not know your microwave wattage, check the label inside the door, the back panel, the manual, or the manufacturer website.
As a general rule, lower wattage requires more time. If a recipe or package assumes a 1100-watt microwave, a 700-watt microwave may need roughly 30 to 50 percent more time. However, do not simply double the time. Microwaves heat unevenly, and too much time can dry out toppings and harden cheese. It is better to use shorter intervals and check frequently.
Power level also matters. High power is usually best for a quick reheat, but medium power can produce more even heating for thick slices. If your microwave has a reheat or pizza setting, it may cycle power automatically. These settings can be convenient, but they are not always perfect. Manual control gives you the best chance to stop at the right moment.
If you regularly reheat pizza, learning your microwave’s behavior is useful. Place one slice on a plate and heat for 30 seconds. If it is barely warm, note that your microwave may need longer. If the cheese is already bubbling, you know to start with 20 seconds next time. Small observations help you build a reliable personal timing guide.
Pizza Type and Slice Thickness
Pizza type affects microwave time because different crusts and toppings hold heat differently. A thin crust slice has less mass and usually heats quickly. A thick crust or deep-dish slice has more bread and moisture, so it needs more time. Stuffed crust pizza can take longer because the cheese inside the crust must warm through. Pizza with heavy toppings, such as meat lover’s or extra cheese, also needs slightly more time than a plain cheese slice.
Slice size matters too. A small triangle from a 10-inch pizza heats faster than a large foldable slice from an 18-inch pizza. If you stack slices or place multiple slices on one plate, the total heating time increases. It is usually better to heat one or two slices at a time for even results. Overcrowding traps steam and can make crusts soggy.
Crust style also changes texture. Thin crust can become crisp if you use a paper towel or crisper, but it can also dry out quickly. Thick crust may stay softer in the center while the edges become hot. Deep-dish pizza can have a dense, moist interior that needs medium power and a longer rest. Frozen pizza has different moisture content and may include a crust designed for microwave crisping.
Toppings create another variable. Pepperoni releases oil when heated, which can make the surface greasy. Vegetables release water, which can soften the crust. Extra cheese takes longer to melt evenly. If your slice has many toppings, start with a slightly longer initial interval but still check halfway through to avoid overheating the crust.
Step-by-Step Guide to Microwaving Pizza
Follow these steps for a quick and reliable reheat. This method works best for leftover slices, but it can also be adapted for frozen slices.
- Place the slice on a microwave-safe plate. Avoid metal, foil, or non-microwave-safe materials. A flat plate helps heat distribute more evenly.
- Use a paper towel under the slice if you want less sogginess. A paper towel absorbs some moisture and can help the bottom crust feel less wet. Do not use a thick towel that traps too much steam.
- Arrange slices with space between them. If heating more than one slice, leave a small gap. Do not overlap slices because overlapping creates cold spots.
- Heat on high for 30 seconds. For a thin slice in a powerful microwave, this may be enough. For thicker slices, begin with 45 seconds.
- Check the pizza carefully. Look at the cheese, touch the crust edge, and see whether the center feels warm. If it is still cold, continue heating.
- Add 10 to 15 seconds at a time. This short-interval method is the best way to answer How Long Do I Microwave Pizza? without overcooking.
- Rotate or reposition if needed. If one side is hotter, rotate the plate or move the slice slightly. This helps compensate for uneven microwave heating.
- Let the slice rest for 30 to 60 seconds. Resting allows heat to spread through the crust and toppings. It also reduces the risk of burning your mouth.
If you are heating frozen pizza, check the package first. Many frozen pizzas have specific microwave instructions, including whether to use a crisping tray. If no instructions are available, heat a frozen slice for 1 minute, check, and continue in 15-second intervals. A whole frozen pizza may need several minutes and should be rotated during cooking.

How to Avoid a Soggy or Rubbery Pizza
The microwave is fast, but it is not naturally good at crisping. It heats water molecules, which can make crust soft and cheese rubbery if the pizza stays in too long. The key is controlling moisture and time. A paper towel under the slice can absorb excess moisture. Some people use a microwave crisper pan, which is designed to heat the bottom of food more effectively. A crisper pan will not make the pizza as crisp as an oven, but it can improve texture.
Short bursts are better than one long cycle. Long microwave times cause cheese proteins to tighten and crust starches to become tough. By heating in intervals, you stop before the texture degrades. If the cheese is melted and the crust is warm, stop. Additional seconds rarely improve flavor and often make the slice worse.
Resting also helps texture. When pizza comes out of the microwave, steam is still moving. Letting it sit for a minute allows moisture to redistribute. The crust may firm slightly, and the cheese will settle. Eating immediately can make the slice seem hotter and softer than it actually is.
If crispness matters most, consider finishing the slice in a skillet or toaster oven after microwaving. A quick 1 to 2 minutes in a hot skillet can crisp the bottom while the microwave has already warmed the toppings. This hybrid method is especially useful for thick slices. However, if speed is your only goal, the microwave alone is perfectly acceptable.
Comparison Table: Microwave Times by Pizza Type
Use this table as a starting point. Times assume high power and one slice unless otherwise noted. Always check and adjust.
| Pizza Type | Typical Microwave Wattage | Starting Time | Notes |
|---|---|---|---|
| Thin leftover slice | 1000-1200W | 25-35 seconds | Check early to avoid drying. |
| Thin leftover slice | 700-900W | 40-50 seconds | Add 10 seconds if still cold. |
| Regular leftover slice | 1000-1200W | 35-45 seconds | Most common scenario. |
| Regular leftover slice | 700-900W | 50-60 seconds | Use medium power for thick toppings. |
| Thick or deep-dish slice | 1000-1200W | 45-60 seconds | Rest before eating. |
| Thick or deep-dish slice | 700-900W | 60-75 seconds | Heat in two intervals. |
| Frozen pizza slice | 1000-1200W | 60-90 seconds | Follow package directions if available. |
| Frozen mini pizza | 1000-1200W | 2-3 minutes | Use crisping tray if included. |
| Whole frozen pizza | 1000-1200W | 4-8 minutes | Rotate as directed. |
Tips and Best Practices
- Start shorter than you think. You can always add time, but you cannot undo overcooking.
- Use a microwave-safe plate. This prevents cracking, melting, or unsafe heating.
- Keep slices separated. Space improves even heating and reduces sogginess.
- Use a paper towel for moisture control. It can absorb some surface moisture without making the pizza dry.
- Check the center, not just the edges. Edges heat faster, while the center may remain cold.
- Let the pizza rest. A short rest improves temperature distribution and texture.
- Adjust for toppings. Heavy toppings and extra cheese need slightly more time.
- Clean the microwave regularly. Food residue can absorb energy and affect heating consistency.
- Write down your ideal time. Once you find a reliable timing for your microwave, save it for future reheats.
- Use medium power for very thick slices. This can reduce hot spots and improve even heating.
Common Mistakes to Avoid
One common mistake is heating pizza for too long because it looks underdone after 30 seconds. Cheese may not be fully bubbly yet, but it can finish melting during resting. Adding too much time often leads to a tough, chewy slice. Another mistake is using maximum time immediately. This is especially risky in high-wattage microwaves, where a slice can go from cold to overheated in seconds.
Overcrowding the plate is another issue. When slices overlap, the overlapping areas stay cold, and you may keep heating until the exposed edges become rubbery. Heat one or two slices at a time for better results. If you need to reheat several slices, do them in batches.
Using the wrong container can also cause problems. Metal pans, foil, or non-microwave-safe plates can spark or melt. Some pizza boxes have metal handles or staples, so do not microwave the box unless it is clearly labeled microwave-safe. A simple plate is the safest choice.
Ignoring food safety is another mistake. Pizza left at room temperature for more than two hours should not be reheated and eaten. If pizza has been sitting out overnight, discard it. Reheating does not make unsafe food safe. Also, avoid reheating pizza multiple times. Reheat only what you plan to eat.
Food Safety and Reheating Temperature
Food safety matters even with a quick microwave reheat. Leftover pizza should be refrigerated within two hours of cooking or delivery. Store it in an airtight container or wrapped tightly to reduce drying and bacterial growth. When reheating, the pizza should be hot throughout, not just warm on the surface.
For general food safety, reheated leftovers should reach 165°F (74°C) internally. You do not need to use a thermometer every time, but the cheese should be melted, toppings should be steaming, and the center should feel hot. If the center is only lukewarm, continue heating in short intervals.
Do not reheat pizza that has been left out too long. The two-hour rule applies to perishable foods, including pizza with cheese and meat. If the room is hot, such as above 90°F, the safe window is even shorter. When in doubt, throw it out. No quick reheat is worth foodborne illness.
Microwaves can create uneven heating, so stirring or rotating food is normally recommended. Pizza cannot be stirred, but you can rotate the plate and let it rest. If you are reheating a large amount, such as several slices stacked or a thick deep-dish piece, use medium power and longer intervals to improve even heating.
Frozen Pizza vs. Leftover Pizza
Frozen pizza and leftover pizza are different products, even if they look similar after cooking. Leftover pizza is already cooked, so reheating only needs to restore temperature and texture. Frozen pizza is uncooked or partially cooked and must be heated thoroughly according to package directions. This means frozen pizza usually requires more time and more careful attention.

For frozen slices, start with 60 seconds and check. The crust may be hard from freezing, so it can take longer to soften. If the pizza includes a crisping tray, use it as directed. Crisping trays are designed to absorb microwave energy and help brown the bottom. Without one, frozen pizza may have a softer bottom.
Whole frozen pizzas often require 4 to 8 minutes, but this varies widely by brand, thickness, and microwave wattage. Some packages recommend a combination of microwave and oven for best results. If the package says to let the pizza stand after cooking, follow that instruction because standing time finishes the heating process.
Leftover pizza is more forgiving. It usually needs less than a minute per slice. The main challenge is preserving texture. Because it is already cooked, overcooking happens quickly. Use short intervals and rest time. If you want a crispier result, combine microwave heating with a skillet or toaster oven.
Alternative Reheating Methods
The microwave is the fastest method, but it is not the only option. An oven or toaster oven can produce a crispier crust. Preheat to about 375°F, place the pizza on a baking sheet or directly on the rack, and heat for 8 to 12 minutes. This takes longer but often tastes closer to fresh pizza.
A skillet is another excellent method. Place the slice in a dry skillet over medium-low heat, cover it, and heat for 5 to 8 minutes. The bottom becomes crisp while the cover traps heat to melt the cheese. You can add a few drops of water to the pan away from the pizza to create steam, but use caution.
An air fryer can reheat pizza in 3 to 5 minutes at around 350°F. It often produces a crisp crust and melted cheese. However, air fryers vary, so check early. The microwave remains the best choice when speed matters, especially at work, in a dorm, or when you only have one slice.
If you combine methods, microwave first for 20 to 30 seconds to warm the center, then finish in a skillet or air fryer for crispness. This hybrid approach reduces total time while improving texture. It is especially helpful for thick or deep-dish slices.

How long do I microwave a frozen pizza slice?
A frozen slice usually takes 60 to 90 seconds in a powerful microwave. Check the package first, because frozen pizza instructions can vary. Heat in intervals and allow standing time if recommended. (See Also:Can You Microwave Lunchables Pizza)
How do I make microwaved pizza crispy?
Use a paper towel under the slice, heat in short bursts, and let it rest. A microwave crisper pan can help. For the best crispness, finish the slice in a hot skillet or air fryer after microwaving.
Why does microwaved pizza become rubbery?
Rubbery pizza usually comes from overheating. Cheese and crust proteins tighten when exposed to too much microwave energy. Use shorter intervals, avoid excessive time, and let the pizza rest before eating.
Is it safe to microwave pizza in the box?
Only if the box is labeled microwave-safe and has no metal staples, handles, or foil. Otherwise, transfer the pizza to a microwave-safe plate. A simple plate is the safest and most reliable option.
Can I microwave pizza that was left out overnight?
No. Pizza left at room temperature for more than two hours should be discarded. Reheating does not make food safe after it has been in the temperature danger zone too long.
