Learning how to cook a spiral ham in the oven is one of the easiest cooking skills to master, even if you’re not super confident in the kitchen.
The best part is that spiral ham is already cooked when you buy it. All you’re really doing is heating it gently and adding a glaze that melts into those gorgeous layers. With the right technique, your ham will come out juicy, tender, and bursting with flavor every single time.
By the end of this guide, you’ll know the exact temperatures, cook times, glazing steps, and pro tips to create the perfect spiral ham for Christmas, Easter, or any celebration.
Why spiral ham is so easy and reliable for holidays
Spiral ham is one of the most forgiving proteins you can serve during the holidays. It’s already fully cooked and spiral sliced, which means:
- It heats quickly
- It absorbs glaze beautifully
- It’s easy to carve
- Guests can serve themselves effortlessly
According to the National Pork Board, over 60 percent of Americans serve ham during winter holidays. That makes it the second most popular main dish after turkey.
Spiral ham is especially loved because:
- It stays juicy when cooked low and slow
- It’s budget friendly compared to beef roasts
- Leftovers are incredibly versatile
- The prep time is almost zero
If you want a dish that looks impressive but requires minimal stress, spiral ham is the answer.
What you need before cooking a spiral ham in the oven
Tools
- Large roasting pan
- Aluminum foil
- Basting brush
- Meat thermometer
- Small saucepan for glaze
Ingredients
- Spiral sliced ham (pre cooked, bone in)
- Brown sugar or honey for glazing
- Optional spices like cinnamon or cloves
- Butter
- Dijon mustard
Choosing the right size ham
A good rule of thumb:
- Bone in spiral ham: 1 pound per person
- Half ham: 1.25 pounds per person
- Leftover lovers: add an extra pound or two
Pro Tip: Bone in hams have better flavor and stay juicier during reheating.
How to cook a spiral ham in the oven
This is where the magic happens. Cooking a spiral ham is incredibly simple, but a few small details make a huge difference in flavor and juiciness.
Step by step instructions
- Preheat your oven to 135 to 150°C (275 to 300°F).
This lower temperature is key for keeping your ham tender. Spiral hams are already cooked, so your goal is gentle reheating, not roasting. A slow warm up helps every slice stay juicy. - Remove any plastic wrapping and discard the glaze packet if you’re making your own.
Most spiral hams come wrapped in a thick plastic layer plus a small moisture packet. Make sure you remove everything, including the small plastic disc sometimes attached underneath the bone. - Place the ham cut side down in a roasting pan.
Cut side down prevents the exposed slices from drying out and lets the heat distribute evenly. If your ham comes with a small net or mesh, remove it before placing it in the pan. - Cover it tightly with aluminum foil.
This creates a mini steam chamber that keeps the ham moist. Press the foil down firmly around the edges of the pan so very little heat escapes. If your ham is taller than your pan, tent the foil instead of pressing it flat. - Bake for 10 to 12 minutes per pound.
This timing ensures the ham warms all the way through without overcooking. For an average 10 pound ham, expect just under 2 hours. Check the internal temperature near the bone toward the end and look for 60°C (140°F). - Add glaze during the last 15 to 20 minutes.
Brush your glaze generously over the surface and between a few slices. Leave the foil off during this final step so the glaze can caramelise. If the edges begin browning too quickly, lightly tent with foil again.
Pro Tip: If you want extra flavour, brush on a thin layer of glaze halfway through cooking, then add the rest at the end for that glossy finish.
How long to cook a spiral ham
Most spiral hams weigh between 8 and 12 pounds, which means:
- 8 pound ham = 1 hour 20 minutes to 1 hour 40 minutes
- 10 pound ham = about 2 hours
- 12 pound ham = 2 hours 15 minutes to 2 hours 30 minutes
You’re simply reheating it gently, not cooking from raw.
Best oven temperatures
Low heat is essential. A high temperature will dry out the slices.
Stick to:
- 135°C for maximum juiciness
- 150°C if you’re short on time
How to prevent a spiral ham from drying out
This is the number one issue people worry about, but it’s easy to avoid.
- Keep the ham tightly covered with foil
- Place it cut side down
- Do not overheat
- Apply glaze at the end, not the beginning
Covering the ham traps steam, which keeps everything moist and tender.
How to tell when it’s fully heated through
Your spiral ham is ready when the internal temperature reaches 60°C (140°F). Use a meat thermometer inserted into the thickest part, avoiding the bone.
How to make the best glaze for spiral ham
A great glaze transforms a simple ham into a glossy, caramelized showstopper.
Classic brown sugar glaze
Ingredients:
- 1 cup brown sugar
- 2 tbsp melted butter
- 1 tbsp Dijon mustard
- 1 tbsp apple cider vinegar
Simmer until smooth, then brush onto the ham in the final 15 minutes.
Honey mustard glaze
- 1/2 cup honey
- 2 tbsp yellow or Dijon mustard
- 1 tbsp lemon juice
This one adds a sweet, tangy finish.
Maple orange glaze
- 1/2 cup pure maple syrup
- Zest of 1 orange
- 1/4 cup orange juice
Perfect for a slightly brighter, citrusy ham.
When to apply the glaze
Always glaze during the last 15 to 20 minutes so it caramelizes without burning.
Pro Tip: Brush some glaze between slices to boost flavor in every bite.
Tips for carving and serving spiral ham
Spiral ham is already sliced, which helps a lot, but carving it cleanly makes serving much easier.
- Place the ham on a stable board
- Use a sharp carving knife
- Cut around the bone to release slices
- Separate sections with tongs
How much to serve
Most guests will eat about:
- 2 slices for lighter appetites
- 3 to 4 slices for holiday meals
Keep a few extras because leftovers are always appreciated.
Serving temperature tips
Spiral ham is best served warm, not piping hot. It keeps flavor better and stays juicier.

Storing, freezing, and reheating leftover spiral ham
Leftover spiral ham is one of the best parts of making this dish. It’s incredibly versatile and reheats beautifully when stored the right way.
Fridge storage
Leftovers should be stored in airtight containers or heavy duty food bags. Make sure the slices have cooled completely before sealing them to avoid trapping steam. Properly stored, spiral ham lasts 3 to 4 days in the fridge.
If you want to keep things extra fresh, wrap the slices in parchment paper before placing them in the container. This helps prevent the edges from drying out and keeps the ham juicy.
Freezing
Spiral ham freezes very well, which makes it perfect for meal prep. Freeze slices in flat layers so they don’t clump together. They stay good for up to 2 months in the freezer.
To thaw, simply move the slices to the fridge and let them defrost overnight. Because spiral ham is pre cooked, the texture stays tender even after freezing.
Pro Tip: Freeze the ham bone separately. It adds amazing flavour to soups, stews, and slow cooker recipes.
Reheating without drying
To reheat leftover spiral ham without losing moisture, warm it low and slow. Set your oven to 120°C, cover the ham tightly with foil, and add a splash of broth, apple juice, or orange juice to the dish. This small amount of liquid creates gentle steam that keeps every slice soft and flavourful.
For smaller portions, you can reheat slices in a pan with a tiny bit of butter for 2 to 3 minutes. This method gives the edges a delicious caramelised finish while keeping the inside tender.
Common mistakes to avoid
- Using too high a heat
- Forgetting to cover with foil
- Applying glaze too early
- Buying too much or too little ham
- Not using a thermometer
Pro Tip: Always save the ham bone for soups. It adds incredible flavor.
