For best results, only reheat 1 slice of ham at a time. In place of a microwave-safe plate, you could also use a paper plate, glass container, or even a microwave-safe plastic container.

If your microwave-safe plate or container has sides, you can also put in around 1 tablespoon (15 ml) of water to stop the ham from drying out. Plastic wrap may also work for this, but increases the chances of melted plastic on your ham. Never use aluminum or tin foil in the microwave.

The amount of time it takes for the ham to heat through will depend on its thickness. Check the temperature of your ham by touching it, or by tearing off a small chunk and eating it to see if it’s warmed through.

If you added a little water to the plate before microwaving, be careful not to touch it as you remove the ham. Any water left on the plate will likely be very hot.

When the pan is at the right temperature, the oil should move freely as you tilt the pan even slightly.

For extra safety, use a pair of tongs to lower the ham into the frying pan. It may help to move the slices of ham around slightly after putting them in the pan. This will stop them from sticking as easily.

If you want to cook the ham further and add marinades, you could also look at cooking ham steaks with your leftover ham.

Make sure to turn off the heat beneath the frying pan once you take the ham out.

Instead of baking paper, you could also use a small amount of cooking oil, such as canola, vegetable, or olive oil, to grease the tray. This will also stop the ham from sticking, but may be more difficult to clean.

To keep your ham slices moist, cover the tray with a sheet of aluminum foil. You could also add 1 tablespoon (15 ml) of water to the base of the rimmed tray to prevent the ham from drying out.

Use a meat thermometer to check the internal temperature of the ham for extra safety. Ham should be reheated to a temperature around 140 °F (60 °C). Flip the slices of ham over every 5 minutes or so to help them heat through evenly.

Serve the ham immediately so that you may eat it while it’s still hot.
