How Long Ham in Oven at 350? Baking Times, Temperatures, and Tips!

ByMeghan Splawn

Introduction

Knowing how long ham in oven at 350? depends on the ham’s weight, whether it is raw or fully cooked, and whether it contains a bone. A small pre-cooked spiral ham may heat through in about an hour, while a large raw bone-in ham can require several hours.

The most reliable baking time is a starting estimate. Always confirm that the ham has reached its recommended safe internal temperature with a food thermometer. Raw ham generally needs to reach 160°F, followed by a rest of at least three minutes. Fully cooked ham intended for reheating only needs to reach 140°F for most consumers.

This guide provides practical times, preparation steps, temperature guidance, glazing instructions, and solutions for common oven problems so you can heat a ham evenly without drying it out or burning the exterior.

Quick Answer

At an oven temperature of 350°F, bake most raw or undercooked hams for approximately 20 to 25 minutes per pound. A 6-pound raw ham may need about two to three hours, while a 10-pound ham may require three to four hours. These are estimates only, so begin checking the internal temperature at least 30 minutes before the expected finishing time.

For a fully cooked bone-in or boneless ham, allow about 15 to 20 minutes per pound. Depending on its size and starting temperature, this usually produces a total reheating time of 20 to 90 minutes. Spiral-cut hams often heat faster, around 10 to 15 minutes per pound, because the slices are already cut and exposed to the oven heat.

Do not rely on estimated time alone. Check the thickest part of the ham and confirm the correct temperature before removing it from the oven. The package directions should take priority when the manufacturer gives a specific heating time or food-safety instruction.

Ham Types and How They Affect Baking Time

Fresh, Raw, or Undercooked Ham

A fresh ham that has not been fully cooked must reach 160°F and rest for at least three minutes. Because the center must warm completely, raw ham usually takes longer than ham labeled “fully cooked.” The bone and surrounding meat may also cook at different rates.

Fresh hams sold for roasting often require roughly 20 to 25 minutes per pound at 350°F. They are a good choice for an oven, but the time increases with weight. A very large raw ham can take four hours or longer, and its outer surface may become dry during the initial heating period. Foiling after the first portion of cooking helps retain moisture.

Fully Cooked or Smoked Ham

A fully cooked ham has already been heated during processing and generally only needs to be warmed for serving. Follow package instructions, which may call for reheating at a lower temperature. At 350°F, it will heat faster, but the exterior is also more likely to dry or brown too quickly.

For most healthy consumers, fully cooked ham should reach 140°F when reheated for leftovers. People who are pregnant or otherwise at higher risk of foodborne illness should heat ham and other deli meats to 165°F.

Spiral-Cut Ham

A spiral-cut ham is often fully cooked, but it may also be sold as raw and uncooked. Read the label before assuming it only needs reheating. Once cooked, the spiral slices shorten the distance the heat must travel. They can require as little as 10 minutes per pound at 350°F, though the package directions remain the best guide.

Boneless and Bone-in Ham

Boneless hams tend to heat slightly faster because there is no bone slowing the transfer of heat. Bone-in hams are more forgiving and can remain juicy, but the meat may finish cooking before the bone. For either style, insert the thermometer into the thickest section rather than touching bone, fat, or the pan.

Baking Time Chart by Ham Weight

The following estimates are useful for planning at 350°F. They assume the ham is fully thawed and begins at refrigerator temperature. Cooking times vary with the shape, bone-in or boneless preparation, starting temperature, oven calibration, and whether the ham is raw or fully cooked.

Ham weight Raw or undercooked ham Fully cooked ham Approximate total time at 350°F
4 pounds 80 to 100 minutes 60 to 80 minutes 1 to 2 hours
6 pounds 2 to 2.5 hours 75 to 120 minutes 1.25 to 2.5 hours
8 pounds 2.5 to 3 hours 2 to 2.5 hours 2 to 3 hours
10 pounds 3.25 to 4 hours 2.5 to 3.25 hours 2.5 to 4 hours
12 pounds 4 to 5 hours 3 to 4 hours 3 to 5 hours

These ranges are not interchangeable. For example, a 6-pound raw ham and a 6-pound fully cooked ham can have very different reheating times. Use the range that matches the ham’s type, then check temperature early and often. A slow-cooker recipe on the package may intentionally use a lower temperature; accelerating it in a 350°F oven can produce hot edges while the center remains cold.

Choosing the Right Oven Temperature

350°F is a useful temperature for baking ham. It is hot enough to cook a raw ham thoroughly while remaining gentle enough to reduce the risk of scorching. A fully cooked ham, however, may not need this much heat because only reheating is required.

  • 300 to 325°F: Gentler heating and useful when preserving moisture, but the ham will take longer. This range is common for long, slow reheating.
  • 350°F: A practical middle ground for raw ham and moderately quick reheating.
  • 375°F: Shortens cooking time but can dry the surface or burn sugary glazes.
  • 400°F or higher: Appropriate for crisping small pieces, but generally unnecessary for a whole ham.

Always preheat the oven. If the ham is large enough to threaten the clearance around your food, do not raise or lower the oven’s temperature setting to make room. Position the rack toward the center so air can circulate around the ham without positioning the pan too close to the heating or fan element. (See Also:How To Get Black Spots Off Oven)

Step-by-Step Baking Instructions

  1. Identify the ham and read the package directions. Determine whether it is raw, fully cooked, boneless, bone-in, or spiral cut. These details affect both the safe temperature and the likely heating time.
  2. Thaw the ham completely. Refrigerate frozen hams for several days before cooking, or thaw them safely in cold water. A frozen center can slow heating, while thawing a large ham at room temperature creates a food-safety risk.
  3. Take the ham out of its wrapper. Remove all plastic, cardboard, foam, and metal packaging unless the manufacturer says to cook the ham in a special oven-safe container. Place it in a sturdy roasting pan or baking dish large enough to catch juices.
  4. Preheat the oven to 350°F. Place the rack in the middle position. A food thermometer, oven mitts, and cooking juices should already be nearby, especially for a large ham that may take several hours.
  5. Prepare the surface as appropriate. Score the rind on a cured or glazed ham in a diamond pattern without cutting into the meat. Light scoring can reduce the outer skin as it heats. For a fully cooked ham with a smooth exterior, do not make deep cuts unless the package directs you to do so.
  6. Add moisture if needed. Pour a small amount of water, apple juice, or another suitable liquid into the pan if the manufacturer recommends it. For very large or lean hams, place a loose tent of heavy-duty foil over the ham during the first part of cooking, then remove it to allow browning.
  7. Begin baking based on the estimated time. Start checking a raw ham about 45 to 60 minutes before the recommended finishing time. Check a fully cooked ham earlier, often 20 to 30 minutes before the estimate because its final heating stage is short.
  8. Add glaze near the end. Brush a sugary glaze over the ham during the final 20 to 30 minutes. Keep it away from the oven’s direct heat, use a light coating, and watch it closely because honey, brown sugar, and fruit preserves can burn quickly at 350°F.
  9. Confirm the safe internal temperature. Raw ham should reach 160°F and rest for at least three minutes. Fully cooked ham should usually reach 140°F for leftover reheating; choose 165°F when required for a higher-risk consumer. Spiral-cut hams may warm unevenly, so test both a thick slice and the thickest area.
  10. Rest and serve the ham. Remove the ham from the oven and allow it to rest for approximately 10 to 20 minutes. A large raw ham may benefit from a 20- to 30-minute rest. Resting allows the hot juices to settle so the ham slices more cleanly.

How to Check Whether the Ham Is Done

A food thermometer is the most accurate way to judge ham. A kitchen thermometer inserted into a bone-in ham may register a misleading temperature if it touches the bone. Position the tip between the bone and the meat, in the thickest part of a boneless ham, or directly in a substantial meaty slice on a spiral-cut ham.

For raw ham, insert the thermometer without starting it from frozen. Some digital thermometers can understate the temperature when the probe is cold, so checking in two or three locations can help identify a cold spot. If a spiral-cut ham has separate portions, test a slice from the center rather than only a small end piece.

You can also check the texture, but this should confirm rather than replace the thermometer. Cooked ham should no longer look raw or translucent inside. The juices should run clear, although color alone does not prove that meat is safe. If the texture is firm but the temperature is below the required level, continue heating.

For slices and small spiral hams, arrange a few pieces in a baking dish and check the thickest slice. For a whole raw ham, wait until the estimated time is nearly complete. If it reaches temperature early, remove it; it does not need additional cooking once safe.

Foil, Browning, and Glazing Tips

At 350°F, a ham may brown before the center is fully heated. This is especially common with pre-cooked hams because the outer layers receive intense heat for a relatively short period. Several techniques can prevent burning while allowing the center to warm.

  • Use foil early. Loosely cover a large or lean ham during the first part of baking. Remove the foil with plenty of time left for the glaze to brown.
  • Lower the heat after cooking. If a fully cooked ham is nearly done, reducing the oven to 250 to 300°F for a short period can help the center heat evenly without overbrowning the outside.
  • Glaze only at the end. Add glaze during the final 20 to 30 minutes, or according to the recipe. Frequent brushing creates a thicker coating that may scorch.
  • Watch sugary toppings. Brown sugar, honey, maple syrup, molasses, and fruit preserves darken faster than the ham cooks.
  • Protect the rind. If the outer rind begins to darken too quickly but the center needs more time, cover only the top with a narrow strip of foil.

A simple glaze can combine brown sugar with mustard and cider vinegar, but it is not necessary for a good baked ham. Brushing with a prepared glaze, using the packaged sauce, or adding a savory seasoning blend are all reasonable options. Avoid adding a thick glaze at the beginning unless its recipe specifically calls for long cooking.

Resting and Serving the Ham

Resting is especially important for a raw roast ham because the hot juices need time to redistribute. Tent the ham loosely with foil during the resting period, but do not leave the ham in a closed pan where accumulated liquid can soak the bottom. Resting times vary with size:

  • Small boneless or spiral hams: about 5 to 10 minutes.
  • Medium hams: approximately 10 to 20 minutes.
  • Large raw hams: around 20 to 30 minutes.

Use a sharp carving knife to remove the rind if appropriate, score the surface lightly, and carve the meat perpendicular to the grain. A spiral ham can generally be separated along its existing cuts. For a bone-in ham, place the cut side up and make even slices toward the bone before working around it.

The juices in the roasting pan can be thickened into a sauce or served separately. Skimming the surface fat is useful for a lighter sauce, but the brown bits at the bottom of the pan may add flavor.

Best Practices for a Juicy Ham

  • Thaw the ham before baking. Frozen or partly frozen ham requires substantially more time and cooks unevenly.
  • Use the package information first. Manufacturer instructions are especially important for spiral hams, pre-cooked hams, and hams containing special curing or glazing ingredients.
  • Choose temperature for the task. Cook raw ham thoroughly, but use gentler heat for a fully cooked ham that only needs reheating.
  • Check before the estimated finishing time. Ovens vary, and a small ham may be done considerably earlier than a chart suggests.
  • Retain pan juices. A small amount of liquid or frequent foil covering can help protect the surface without drowning the ham.
  • Rotate only when practical. A very large or unusually shaped ham can be turned after the initial heating period, but careful lifting with two people is safer than risking a hot pan.
  • Use two thermometers if you lack experience. Checking multiple locations helps reveal cold sections in a spiral ham or an irregularly shaped roast.
  • Let the ham rest before carving. Skipping the rest may cause the juicy center to run out as you slice.

Choosing a ham that fits your household needs can also prevent waste. Very large hams cook well and freeze, but they require more oven space, planning, and storage. A smaller ham that will be eaten promptly may be easier to cook evenly.

Common Mistakes and How to Fix Them

Cooking only by the listed time

Package times are estimates, not guarantees. The ham’s starting temperature, oven effectiveness, size, and shape can all change the result. Begin checking early with a thermometer so the ham can come out as soon as it reaches the target temperature.

Cooking a frozen ham

A frozen ham may burn on the outside while remaining frozen or dangerously cold in the center. The safest and most even method is to thaw it in the refrigerator. If you are short on time, use cold water in leak-proof packaging, change the water regularly, and cook the ham immediately after thawing.

Leaving packaging in the oven

Never bake plastic, cardboard, foam, or non-oven-safe foil in a roasting pan. Remove the outer packaging and follow any special instructions for vacuum-packed hams. If the label is unclear, transfer the ham to a conventional oven-safe dish.

Adding glaze too early

Sweet glazes can turn dark or bitter before the ham finishes cooking. Apply a light layer near the end, brush it evenly, and check it every few minutes. If it darkens quickly, cover the top loosely with foil.

Measuring against the bone

A thermometer touching bone can give an inaccurate result and may be difficult to insert. Measure in the thickest meat next to the bone or in the center of a boneless or spiral-cut ham. Take multiple readings if the ham has unusually thick and thin areas. (See Also:Can You Warm Pizza Box In Oven)

Reheating too slowly at 350°F

A fully cooked ham held in the food-safe danger zone needs to be reheated promptly. It should reach 140°F, or 165°F for people at higher risk, rather than remaining in the oven at a low temperature for many hours. Reheat only the amount you plan to use.

Carving immediately

A ham straight from the oven can release too much juice during cutting. Let it rest for the recommended period, keep it loosely covered, and use a long, sharp carving knife. The resulting slices will be cleaner and retain more moisture.

Storing and Reheating Leftover Ham

Refrigerate leftover ham within two hours of serving. Place it in shallow, airtight containers or seal it tightly on a plate and refrigerate promptly. Properly stored cooked ham generally keeps for three to four days in a refrigerator set at 40°F or colder.

To reheat an individual serving, place it in a skillet with a splash of water or broth, cover the pan, and heat over medium-low. Alternatively, cover the ham with foil and warm it in a 325 to 350°F oven. Heat the thickest piece until it reaches 140°F, or 165°F if required for a higher-risk consumer.

For longer storage, divide the ham into meal-sized portions, wrap or seal each portion, and freeze it. Thaw in the refrigerator rather than on the counter. An oven is not the best method for reheating a frozen whole ham because the exterior can warm before the center thaws.

Frequently Asked Questions

How long should I bake a ham in the oven at 350°F?

Allow about 20 to 25 minutes per pound for a raw ham and 15 to 20 minutes per pound for a fully cooked ham at 350°F. A spiral-cut ham may need only 10 to 15 minutes per pound. Treat these as estimates and begin checking the temperature before the expected finishing time.

How long does an 8-pound ham take at 350°F?

An 8-pound raw ham usually takes about 2.5 to 3 hours at 350°F. A fully cooked 8-pound ham may take roughly 2 to 2.5 hours, while a fully cooked spiral-cut version may heat faster. Confirm that the thickest part reaches 160°F for raw ham or 140°F for most reheated cooked ham.

How long do I cook a raw ham at 350°F?

Cook a raw ham at 350°F until the thickest meaty section reaches 160°F and rests for at least three minutes. Start with an estimate of 20 to 25 minutes per pound, but begin checking early because weight and shape are not the only factors. Use package directions as the starting point when they are available.

How long do I reheat a fully cooked ham at 350°F?

Reheat a fully cooked ham at 350°F until the thickest part reaches 140°F. Plan on about 15 to 20 minutes per pound, or roughly 10 to 15 minutes per pound for a spiral-cut ham. Check early because smaller hams can become dry before a large ham’s center reaches the target temperature.

How long do I heat a spiral ham at 350°F?

Most fully cooked spiral hams need around 10 minutes per pound at 350°F, but package instructions may call for a lower temperature or a different time. Spiral hams can warm unevenly, so check a slice from the thickest central area rather than testing only one small end piece. (See Also:How To Dehydrate In Your Oven)

Does a boneless ham cook faster than a bone-in ham?

A boneless ham often heats somewhat faster because heat does not need to pass through a bone. It may also dry out more easily because it lacks the protection provided by the bone. The difference is usually modest, so compare similar types of hams and use temperature—not weight alone—to determine doneness.

Should I cover ham with foil while baking?

Yes, if a large or lean ham is browning too quickly. Cover it loosely with foil during the early part of cooking, then remove the foil for the final 20 to 30 minutes so the surface can brown and the glaze can set. For a spiral ham, foil can trap moisture over the cut slices, so watch it carefully.

What internal temperature is safe for baked ham?

Raw, uncooked ham should reach 160°F and rest for at least three minutes. Fully cooked ham being reheated for leftovers should reach 140°F for most healthy consumers. Pregnant individuals and those with compromised immune systems should reheat ham to 165°F. Always use a calibrated food thermometer.

When should I add glaze to ham at 350°F?

Add glaze during the final 20 to 30 minutes unless the recipe says otherwise. Hams with brown sugar, honey, or fruit glaze can burn quickly at 350°F. Brush on a light, even layer and check frequently, especially if your oven browns food faster than average.

Can I bake a frozen ham at 350°F?

It is better to thaw the ham first. Baking it directly from frozen can leave the center undercooked while the exterior burns. Thaw in the refrigerator whenever possible, or use a safe cold-water method and keep the ham in leak-proof packaging. Never leave it on a counter at room temperature until fully thawed.

Conclusion

The practical answer to how long ham in oven at 350? is usually 20 to 25 minutes per pound for raw ham and 15 to 20 minutes per pound for fully cooked ham. Spiral-cut versions may heat in as little as 10 to 15 minutes per pound. Weight, bone content, starting temperature, and the ham’s preparation all affect the total cooking time.
