You’re ready to bake a ham, and the oven is set to 350°F. Knowing exactly how long to bake ham in oven at 350 is the key to a perfect result. This temperature is the standard for a reason—it heats the ham through gently, warms any glaze, and gives you a tender, juicy centerpiece for your meal. Whether it’s a holiday dinner or a special Sunday supper, this guide will walk you through every step. We’ll cover different ham types, preparation tips, and precise timings so you can cook with confidence.
How Long To Bake Ham In Oven At 350
The standard baking duration for a ham at 350°F is about 15-20 minutes per pound. But that’s just the starting point. The total time depends heavily on what kind of ham you have. Is it fully cooked or partially cooked? Bone-in or boneless? The answer changes the clock. A fully cooked, bone-in ham, which is the most common type you’ll find, typically needs that 15-20 minute per pound rule. A boneless ham might cook a bit faster. Always, always use a meat thermometer to be sure. The goal is an internal temperature of 140°F for a fully cooked ham that you’re just reheating.
Understanding Your Ham: The First Step to Perfect Timing
Before you preheat the oven, you need to read the label on your ham. This is the most important step. The packaging tells you exactly what you’re working with. Look for key phrases that determine your baking time.
- Fully Cooked or “Cook Before Eating”: Most hams sold in the U.S. are fully cooked. This means they have been smoked or cured and are safe to eat without further cooking. You are essentially reheating it to serving temperature. A “Cook Before Eating” ham is only partially cooked and requires thorough cooking to a higher internal temperature for safety.
- Bone-In, Bone-Out, or Spiral-Cut: A bone-in ham takes longer to heat through but often has more flavor. A boneless ham heats faster and is easier to slice. A spiral-cut ham is fully cooked and pre-sliced, which means it heats much quicker but can also dry out faster.
- Weight: Know the weight. This is non-negotiable for calculating your baking time. If it’s still in the packaging, the weight is printed there.
Step-by-Step Guide to Baking a Ham at 350°F
Follow these steps for a simple, no-fail baked ham. The process is straightforward when you take it one step at a time.
1. Preparation: Thawing and Preheating
If your ham is frozen, you must thaw it safely in the refrigerator. This can take several days—plan for about 24 hours for every 4-5 pounds. Never bake a ham from frozen, as the outside will overcook before the inside is safe to eat. When you’re ready to cook, take the ham out of the fridge for about an hour to take the chill off. This helps it heat more evenly. Preheat your oven to 350°F.
2. Preparing the Pan and the Ham
Use a large roasting pan with shallow sides. A rack is helpful but not essential. If you don’t have a rack, you can create a “nest” with foil ropes or sliced onions to keep the ham out of the drippings. Place the ham flat-side down (the cut side) in the pan. If it has a layer of skin or fat, you can score it in a diamond pattern. This isn’t just for looks; it helps render fat and allows glazes to penetrate.
3. To Cover or Not to Cover?
Covering the ham with foil for most of the baking time is the best practice. This keeps it moist and prevents the outside from drying out before the center is warm. For a fully cooked ham, you’ll cover it tightly with foil for the majority of the estimated baking time. You’ll remove the foil during the last 30-45 minutes to apply glaze and let the exterior caramelize.
4. Calculating and Checking the Time
Here is a simple chart for a fully cooked ham at 350°F:
- Bone-In Ham: 15-18 minutes per pound.
- Boneless Ham: 18-24 minutes per pound.
- Spiral-Cut Ham: 10-14 minutes per pound (covered the entire time to prevent drying).
For a “Cook Before Eating” ham, you must cook it to an internal temperature of 160°F. This will take longer, roughly 22-26 minutes per pound. The only reliable way to know it’s done is with a good meat thermometer. Insert it into the thickest part of the meat, avoiding the bone. For a fully cooked ham, aim for 140°F. For a partially cooked ham, aim for 160°F.
5. Glazing and Final Baking
Glaze is applied at the end. About 30-45 minutes before the ham is done, take it out of the oven. Increase the oven temperature to 400°F. Remove the foil cover. Brush on your glaze—whether it’s a simple brown sugar and mustard mix, a honey maple syrup, or a fruit-based glaze. Return the ham to the hotter oven, uncovered. This allows the glaze to bubble, thicken, and become a beautiful, shiny coating. Brush with additional glaze every 10-15 minutes until the ham reaches its final temperature.
6. Resting is Crucial
Once the ham hits its target temperature, take it out of the oven. Tent it loosely with foil and let it rest for 15-25 minutes. This allows the juices, which have been driven to the center by the heat, to redistribute throughout the meat. If you slice it immediately, all those flavorful juices will run out onto the cutting board, leaving you with a drier ham.
Common Ham Types and Their Specific Timings at 350°F
Let’s break down the timing for specific ham scenarios you might encounter.
Bone-In Whole Ham (Fully Cooked, 10 lbs)
This is a classic. At 15-20 minutes per pound, a 10-pound ham will need 2.5 to 3.5 hours in the oven, plus resting time. Always start checking the temperature about 30 minutes before the lowest estimated finish time. Ovens can vary, and the shape of the ham can effect cooking time.
Half Ham (Bone-In, 5-7 lbs)
A half ham is simply one half of a whole ham, either the shank end (pointier, easier to carve) or the butt end (more rounded, often meatier). Use the same per-pound timing. A 6-pound half ham will take roughly 1.5 to 2 hours.
Spiral-Cut Ham (Fully Cooked, 8 lbs)
Because it’s pre-sliced, heat penetrates much faster. Keep it covered the entire time to prevent it from drying out. At 10-14 minutes per pound, an 8-pound spiral ham will take about 1 hour and 20 minutes to 1 hour and 50 minutes. Check the temperature early and often, inserting the thermometer into the center of the meat (not between slices).
Boneless Ham (Fully Cooked, 3 lbs)
A smaller, boneless ham is great for smaller gatherings. It heats faster due to the lack of bone and its compact shape. At 18-24 minutes per pound, a 3-pound boneless ham will be ready in about 54 to 72 minutes. It’s still important to check the internal temperature.
How to Make a Simple, Classic Glaze
A glaze adds flavor and a beautiful finish. You don’t need anything complicated. Here’s a basic, reliable recipe you can adjust.
- 1 cup packed brown sugar
- 1/4 cup Dijon mustard or whole-grain mustard
- 2 tablespoons apple cider vinegar or pineapple juice
- Optional: a pinch of cloves or a tablespoon of maple syrup
Mix all ingredients in a bowl until it forms a thick paste. Apply during the last 30-45 minutes of baking as described above. If you want a fruitier glaze, you can substitue some of the brown sugar with orange marmalade or apricot preserves.
Frequently Asked Questions (FAQ)
Do you bake a ham at 325 or 350?
You can bake a ham at either temperature. 350°F is the standard and most common because it provides a good balance of gentle heating and efficient timing. Baking at 325°F will take longer but can be slightly more forgiving, reducing the risk of over-browning. Stick with 350°F for the timings in this guide.
How long do you heat a 12 pound ham at 350?
For a fully cooked, bone-in 12-pound ham, plan for 3 to 4 hours at 350°F (15-20 min/lb). Always use a meat thermometer to confirm it has reached 140°F internally.
How long does it take to cook a precooked ham?
A precooked (fully cooked) ham needs about 15-20 minutes per pound at 350°F to reach the recommended serving temperature of 140°F. The “cooking” is really just a thorough reheating.
Do you put water in the pan when baking a ham?
It’s not usually necessary. The ham releases its own juices as it heats. However, adding a half-inch of water, broth, or even pineapple juice to the bottom of the pan can create steam and provide extra insurance against drying out, especially for longer bake times. It also makes deglazing the pan for gravy easier later.
Troubleshooting Common Ham Problems
Even with careful planning, things can happen. Here’s how to fix common issues.
Ham is Dry
Dry ham is often caused by overcooking. Using a thermometer is the best prevention. If you have a “Cook Before Eating” ham and cooked it to 160°F, it will be less juicy than a fully cooked one reheated to 140°F. Slicing it too soon without resting also releases juices. Next time, try basting the ham with pan juices or a bit of broth during baking, and ensure it’s covered with foil for most of the time.
Glaze is Burning
If your glaze contains a lot of sugar, it can burn in a 400°F oven. If you see it getting too dark too fast, loosely tent the ham with foil again. You can also try applying the glaze in the last 20-25 minutes instead of 30-45. Keeping the oven at 350°F for the glazing phase can also help, though it won’t caramelize quite as quickly.
Ham Isn’t Browning
If the exterior looks pale, the oven temperature might be off. Use an oven thermometer to check. For the final browning phase, make sure the oven is at 400°F and the ham is uncovered. If you applied a glaze, the sugar in it should promote browning. A quick tip: you can turn on the broiler for the last 2-3 minutes, but watch it constantly to avoid burning.
Carving and Storing Leftovers
For a bone-in ham, place it flat-side down on your cutting board. Use a long, sharp knife to make slices perpendicular to the bone. After you’ve made several slices along one section, run your knife along the bone to release them. Turn the ham and repeat. For a spiral ham, simply follow the pre-cut slices. Leftover ham should be cooled and then wrapped tightly or placed in an airtight container. It will last in the refrigerator for 3-4 days. You can also freeze sliced ham for 1-2 months. The bone is perfect for adding to soups or beans for extra flavor.
Baking a ham at 350°F is a simple process that yields impressive results. The key is knowing what type of ham you have, calculating the time based on its weight, and trusting a meat thermometer over the clock. With a little preparation and patience, you can serve a centerpiece that’s flavorful, juicy, and perfectly cooked. Remember to let it rest before carving, and save that bone for your next pot of soup.
