How Do You Heat Up Sliced Ham In The Oven?
To heat up sliced ham in the oven, preheat the oven to 350°F (175°C). Place the slices of ham on a baking sheet and bake for 10-15 minutes, or until heated through. You can cover the ham with foil to prevent it from drying out. If you want the slices to be crispy, you can remove the foil for the last few minutes of baking. Remove the ham from the oven and let it rest for a few minutes before serving.
