While you're waiting for the oven to come to temperature, place your ham in a roasting pan.

How to reheat frozen ham. Take a dish that’s been in the fridge for a while to the microwave. The best way to do this is to place the ham on a rack in a roasting pan. After wrapping your ham, place it on a baking tray with the cut side down.

Optionally put a bit of water in the bottom of the pan to introduce. The goal is to reheat the ham without drying it out. Add the ham and drizzle some leftover juices or stock over the slices.

If you are reheating ham in the microwave, it is important that you use the correct cooking times. To serve warm, preheat your oven to 350. Remove the ham from the packaging, wrap it in foil, and reheat until it’s ready to serve.

Cook the ham immediately if thawing with cold water to avoid the risk of bacteria forming. While precooked hams can be eaten at room temperature immediately after thawing, they're often heated and glazed for a more elegant presentation. Make sure you wrap it in aluminum foil, as this will allow the heat to circulate and heat the ham evenly.

Place slices of ham in a baking pan and cover with aluminum foil. If you have a probe thermometer, insert it into the ham to carefully track the temperature over time, adding more ice if the temperature approaches 40 degrees fahrenheit. Step 2 heat your oven to 325.
