If you’re planning a holiday meal or a special Sunday dinner, knowing how long to cook a ham in oven at 350°F is essential. This temperature is a popular choice because it cooks the ham gently and evenly, resulting in a juicy, flavorful centerpiece for your table. The answer, however, isn’t just one number. It depends completely on the type of ham you have. A fully cooked ham just needs to be warmed through, while a fresh ham requires thorough cooking to a safe internal temperature.
This guide will walk you through everything. We’ll cover the different ham types, preparation, and precise cooking times. You’ll also get tips for glazing and storing leftovers. Let’s get your ham ready for the oven.
How Long To Cook A Ham In Oven At 350
As a general rule, plan for about 15-20 minutes per pound for a fully cooked ham that you are reheating. For a ham that needs to be cooked (like a fresh ham), plan for 22-26 minutes per pound. Always, always use a meat thermometer to check for doneness. The internal temperature is your true guide, not just the clock.
Understanding Your Ham: The Most Important First Step
Before you preheat the oven, you must identify what kind of ham you have. Check the label carefully. This decision impacts your cooking time and food safety.
- Fully Cooked or “Cook Before Eating”: Most hams sold in supermarkets are fully cooked. They have been smoked or cured and are safe to eat without further cooking. Heating them is for flavor and texture. “Cook Before Eating” hams are also cured but require thorough cooking in your oven.
- Fresh Ham: This is uncured, unsmoked pork from the leg. It looks like a giant pork roast. It must be cooked to a safe internal temperature.
- Bone-In vs. Boneless: A bone-in ham will generally take a bit longer to heat through than a boneless ham of the same weight. The bone, however, adds incredible flavor.
- Whole, Half, or Spiral-Sliced: A whole ham is large (12-16 lbs). A half ham is more manageable (5-8 lbs). Spiral-sliced hams are fully cooked and pre-sliced for easy serving, but they can dry out faster.
Step-by-Step: Preparing and Cooking Your Ham
1. Preparation: Thawing and Trimming
If your ham is frozen, thaw it safely in the refrigerator. This can take 3-5 days for a large ham. Never thaw at room temperature. Once thawed, remove the ham from its packaging. Pat it completely dry with paper towels. If it has a thick skin or excess fat, you can score it in a diamond pattern. This helps render the fat and allows glazes to penetrate. Place the ham, cut-side down, in a large roasting pan or baking dish. A rack in the pan is helpful but not required.
2. To Cover or Not to Cover?
Covering the ham with foil for most of the cooking time keeps it moist. For a fully cooked ham you’re reheating, cover it tightly with foil for the initial heating phase. Remove the foil during the last 30-45 minutes to allow the glaze to caramelize and the exterior to brown. For a fresh ham that needs cooking, covering it for the first part helps it cook evenly without drying out.
3. The Cooking Process and Timing Chart
Preheat your oven to 350°F (175°C). Use this chart as a starting point, but remember the thermometer is final authority.
- Fully Cooked Ham (Bone-In): 15-18 min/lb. Target internal temp: 140°F.
- Fully Cooked Ham (Boneless): 18-24 min/lb. Target internal temp: 140°F.
- “Cook Before Eating” Ham: 22-25 min/lb. Target internal temp: 160°F.
- Fresh Ham (Uncured): 24-28 min/lb. Target internal temp: 145°F (followed by a 3-minute rest).
Insert the meat thermometer into the thickest part of the ham, avoiding the bone if it has one. Check the temperature about 30 minutes before the expected finish time.
4. Glazing for Flavor and Shine
A glaze adds sweet, sticky, and savory flavor. Apply it during the last 45-60 minutes of cooking. After removing the foil, brush on a layer of glaze every 15 minutes. This builds up a beautiful, glossy coating. Popular glaze ingredients include brown sugar, honey, maple syrup, mustard, pineapple juice, or cloves.
Common Mistakes to Avoid
Even experienced cooks can make a few errors when cooking a large ham. Here’s what to watch out for.
- Not Using a Thermometer: Guessing is a surefire way to end up with dry or undercooked meat. It’s the single most important tool.
- Overcooking: This is the biggest cause of dry, tough ham. A fully cooked ham only needs to reach 140°F. Continuing to cook past that point will squeeze out all the juices.
- Glazing Too Early: If you put a sugar-based glaze on at the start, it will likely burn by the time the ham is done. The high sugar content caramelizes quickly.
- Not Resting the Ham: Let the ham rest for 15-25 minutes after taking it out of the oven. This allows the juices, which have rushed to the surface, to redistribute throughout the meat. Slicing immediately will cause all those good juices to run out onto the cutting board.
Carving and Serving Your Perfect Ham
For a bone-in ham, place it on a sturdy cutting board with the flat, cut side down to stabilize it. Use a long, sharp knife. For a half ham with the bone, start by slicing perpendicular to the bone. Then, run the knife along the bone to release the slices. For a spiral-sliced ham, the work is mostly done! Just follow the existing slices. Serve the ham warm with your favorite sides like scalloped potatoes, green beans, or rolls.
Storing Leftovers and Reheating
Ham makes fantastic leftovers. Let any leftover ham cool completely. Wrap it tightly in plastic wrap or aluminum foil, or store it in an airtight container. It will keep in the refrigerator for 3-4 days. For longer storage, you can freeze sliced ham for up to 2 months. To reheat, place slices in a baking dish with a bit of broth or water, cover with foil, and warm in a 325°F oven until heated through. This prevents it from drying out again.
Frequently Asked Questions (FAQ)
How long do I cook a 10 lb ham at 350 degrees?
For a 10 lb fully cooked ham, heat it for about 2.5 to 3 hours (15-18 min/lb). Always check that the internal temperature reaches 140°F.
Do you cook a ham at 325 or 350?
350°F is standard and works great. 325°F is a bit slower and gentler; it might take slightly longer but can be good for very large hams to ensure even heating without over-browning.
How long to cook a precooked spiral ham at 350?
A precooked spiral ham heats faster because the slices expose more surface area. Plan for about 10-12 minutes per pound. Cover it tightly with foil for most of the time to prevent drying, and check the temp early to avoid overcooking.
What is the best way to keep ham moist?
Covering it with foil for the majority of the cooking time is the best method. Adding a little liquid (like water, apple juice, or broth) to the bottom of the pan can also create steam. Also, avoid overcooking it past it’s recommended temperature.
Do you put water in the pan when baking a ham?
It’s not required, but adding about 1-2 cups of water, broth, or juice to the bottom of the roasting pan can help keep the oven moist and prevent any drippings from burning. It also makes a base for gravy if you want.
Final Tips for Success
Read your ham’s label first. Invest in a reliable instant-read meat thermometer—it’s a game-changer. Allow plenty of time for thawing if needed. Don’t forget the resting period after cooking; it makes a significant difference in juiciness. Finally, have fun with the glaze. You can mix and match flavors to suit your taste. A well-cooked ham is a centerpiece that feeds a crowd and provides meals for days, so mastering this skill is truly worth it. With these guidelines, your next ham will turn out perfectly.
