How Long Does a Spiral Ham Take in a Roaster Oven?

For bone-in spiral cut ham, follow these approximate roasting times:

5 lb ham: 1 hour 15 minutes to 1 hour 30 minutes
7 lb ham: 1 hour 45 minutes to 2 hours
10 lb ham: 2 hours 30 minutes to 3 hours
12 lb ham: 3 hours to 3 hours 30 minutes
15 lb ham: 3 hours 45 minutes to 4 hours 15 minutes

Cook spiral ham at 275°F, allowing 15 to 20 minutes per pound. The ham is done when the internal temperature reaches 140°F.

Spiral slicing helps the ham roast evenly. Keeping it loosely covered with foil prevents drying out. Glaze during the last 30-60 minutes.

How Long Does Boneless Ham Take in a Roaster Oven?

3 lb boneless ham: 1 hour 15 minutes to 1 hour 30 minutes
5 lb boneless ham: 1 hour 45 minutes to 2 hours
7 lb boneless ham: 2 hours 15 minutes to 2 hours 45 minutes

Check temperature and glaze during last 15 minutes or so of roasting. Cook to 140°F internally.

Regular Bone-In Ham Roasting Times

For hams without spiral slicing, allow more time due to their shape and density. Cook at 325°F using this timetable:

5 lb ham: 1 hour 45 minutes to 2 hours 30 minutes
7 lb ham: 2 hours 30 minutes to 3 hours 15 minutes
10 lb ham: 3 hours 30 minutes to 4 hours 15 minutes

Add about 20 minutes per pound for regular hams. Check internal temp and glaze toward the end of roasting.

Key Tips for Roasting Ham

Always use a meat thermometer for doneness, regardless of time.
Let ham rest 10-15 minutes before carving for juicy slices.
For hams over 10 lbs, use an 18-22 quart roaster oven.
Keep foil tent slightly open during glazing for browning.
Add liquids like broth or juice to the oven bottom.

How to Tell When Ham is Done

An instant-read thermometer inserted into the thickest part of the ham is the most accurate test for doneness.

Whole ham, cooked or spiral-cut: 140°F minimum
Pre-sliced, boneless ham: 130°F minimum

If thermometer is not available, the ham should be fork tender when pierced. Meat will pull back from the bone when fully cooked.
