How do I reheat a frozen ham after thawing safely?

Safely Reheating Thawed Ham

After thawing in the refrigerator, reheating ham safely and evenly is straightforward. The goal is to bring the internal temperature to at least 140°F (60°C) for pre-cooked hams and 165°F (74°C) for leftovers reheated for safety.

Oven reheating method:

  • Preheat oven to 325°F (163°C). Place the thawed ham in a roasting pan with 1/2 cup of liquid (water, cider, or stock) to maintain moisture.
  • Cover tightly with foil and heat until internal temperature reaches 140°F for fully cooked hams or 165°F if reheating leftovers. Allow roughly 10–15 minutes per pound as a guideline, but always rely on a meat thermometer.

Microwave or stovetop:

  • For slices, use the microwave at medium power with a damp paper towel or small splash of liquid, heating in short intervals until warmed through. - Stovetop reheating: pan-sear slices on low heat with a bit of butter and a splash of stock.

List of reheating tips

  • Don’t refreeze thawed ham unless it was cooked after thawing. - Let the ham rest briefly before slicing for better juiciness. - Use a probe thermometer to confirm safe temperatures.

Following these steps ensures safe reheating while preserving texture and flavor.
