Cook ham time depends on whether it’s fully cooked or raw, and on the weight. For a fully cooked ham, a good rule is about 15 to 20 minutes per pound at 325°F , until it reaches 140°F inside; for a fresh raw ham, it needs to reach 160°F inside, which usually takes longer.

Quick guide

  • Fully cooked bone-in ham: about 15 to 20 minutes per pound at 325°F.
  • Fully cooked boneless ham: about 18 to 24 minutes per pound at 325°F.
  • Heat to the right temp: 140°F for reheating a fully cooked ham, 160°F for cooking a raw ham.

Example

A 10-pound fully cooked bone-in ham usually takes about 2.5 to 3.5 hours in the oven at 325°F.

Helpful tip

Use a meat thermometer and check the thickest part, not touching the bone, because oven time can vary by size and shape.
