Yes — you can cook a ham in a crock pot, and it works especially well for a fully cooked ham that you’re reheating gently. Slow-cooker recipes commonly use low heat for about 2 to 6 hours , depending on ham size, and aim for an internal temperature of 140°F for reheating a fully cooked ham.

Quick Scoop

A crock pot is a solid option if you want:

  • Less oven space used.
  • A very tender, moist ham.
  • An easy glaze that cooks right along with the meat.

Best Approach

For best results:

  1. Use a fully cooked spiral ham or other fully cooked ham.
  2. Place it in a large slow cooker that fits it without forcing.
  3. Add a little liquid or glaze so it stays moist.
  4. Cook on low until heated through, usually around 3 to 4 hours for many hams, though larger ones may take longer.

Safety Note

If the ham is already fully cooked, you’re reheating it, not cooking it from raw. The target is 140°F internal temperature , which is the standard cited in the recipes I found.

Simple Example

A basic version looks like this:

  • Put the ham cut side down in the crock pot.
  • Add brown sugar, pineapple juice, maple syrup, or your preferred glaze.
  • Cook on low until warm and tender.
  • Spoon the juices over the ham before serving.
