Spiral sliced ham heats evenly in the oven, and a simple glaze brushed on during the final minutes adds shine and flavor. If you want to know how to cook spiral sliced ham in the oven without drying it out, the process is easier than you think. The ham is already fully cooked, so your job is mostly about warming it through gently and adding a nice finish.
This guide walks you through temps, timing, glazing, and serving. You will get a tender, juicy ham every time.
What You Need Before You Start
A spiral sliced ham is cured and smoked before it ever reaches the store. That means you are reheating, not cooking from raw. Keep that in mind and you will avoid the most common mistake: overcooking.
Here is what to gather:
- One spiral sliced ham, bone-in or boneless, 7 to 10 pounds
- A roasting pan with a rack, or a disposable foil pan
- Aluminum foil
- A meat thermometer
- Glaze ingredients of your choice
If your ham came with a glaze packet, you can use it. If not, a mix of brown sugar, honey, and mustard works great. More on that below.
How Long To Cook Per Pound
Plan on about 10 to 12 minutes per pound at 325°F. A 9-pound ham usually takes around 1 hour and 30 minutes to 1 hour and 45 minutes. Always check the internal temp rather than trusting the clock alone.
How To Cook Spiral Sliced Ham In The Oven
Follow these steps in order and you will get a moist, evenly warmed ham with a glossy glaze.
Step 1: Let The Ham Sit Out
Take the ham out of the fridge 30 to 60 minutes before baking. This helps it heat more evenly. Remove all packaging, including the plastic disc over the bone if there is one.
Step 2: Heat Your Oven
Set the oven to 325°F. Place a rack in the lower middle position so the pan has room and the top does not brown to fast.
Step 3: Prep The Pan
Put the ham cut side down in your roasting pan. Add about 1/4 inch of water or broth to the bottom. This creates steam and keeps the meat from drying out.
Step 4: Cover And Bake
Tent the whole ham loosely with foil. Do not wrap it tight, you want some air to move around. Bake for roughly half the total estimated time.
For a 9-pound ham, that is about 45 minutes covered.
Step 5: Uncover And Glaze
After the first stretch, pull the foil back. Brush on a generous layer of glaze. Return the ham to the oven uncovered.
Brush more glaze every 15 minutes. Two or three rounds is plenty.
Step 6: Check The Temperature
Insert a thermometer into the thickest part, away from bone and fat. You are looking for 135°F to 140°F. Once it hits that range, pull it out.
Do not let it go past 145°F or the slices will start to dry.
Step 7: Rest Before Slicing
Cover the ham loosely with foil and let it rest 10 to 15 minutes. This lets the juices settle. Then slice along the existing cuts and serve.
Simple Glaze Ideas That Work
You do not need anything fancy. These three options cover most tastes.
- Classic brown sugar: 1 cup brown sugar, 2 tablespoons Dijon mustard, 2 tablespoons apple cider vinegar
- Honey mustard: 1/2 cup honey, 1/4 cup yellow mustard, pinch of cloves
- Maple orange: 1/2 cup maple syrup, 1/4 cup orange juice, 1 teaspoon orange zest
Whisk the ingredients in a small bowl. Warm it slightly so it brushes on smooth. If you want a thicker glaze, simmer it on the stove for a few minutes first.
When To Apply The Glaze
Add glaze only in the last 30 to 45 minutes of baking. Sugar burns fast, and early application can leave you with a dark, bitter crust. Wait until the ham is mostly heated through.
Common Mistakes To Avoid
Even a simple bake can go wrong. Watch out for these.
- Overcooking. The ham is already cooked. You are just warming it. Pull it at 140°F.
- Skipping the water in the pan. That bit of liquid keeps the oven air moist.
- Glazing to early. Wait until the final stretch.
- Cutting right away. Resting keeps the slices juicy.
- Baking at high heat. 325°F is the sweet spot. 400°F will dry out the edges.
Storing And Reheating Leftovers
Leftover ham keeps well. Store slices in a sealed container in the fridge for 3 to 5 days. For longer storage, freeze portions in freezer bags for up to 2 months.
To reheat, place slices in a covered dish with a splash of water or broth. Warm at 300°F for 10 to 15 minutes. A microwave works too, just cover the plate and use short bursts so the meat does not toughen.
What To Do With The Bone
Do not toss the bone. It adds great flavor to soups, beans, and collard greens. Wrap it and freeze it if you are not using it right away.
Final Tips For A Perfect Ham
Buy the right size. Figure about 1/2 pound per person if you want leftovers, 1/3 pound if you do not.
Let the ham come to room temp before baking. Use a thermometer, not just time. Glaze late and glaze often. Rest before slicing.
Follow those rules and your spiral sliced ham will come out tender, warm all the way through, and coated in a shiny glaze that looks like you fussed, even though you did not. Thats really all there is to it.
