When you cook prime rib, you may end up with leftovers. Freezing the prime rib preserves the flavor and allows you to enjoy the beef at a later date. Since the prime rib leftovers are already cooked, they only need to be reheated to a safe internal temperature. Reheating the prime rib safely and properly keeps the meat juicy.

Step 1

Thaw frozen prime rib in the refrigerator overnight.

Step 2

Wrap the thawed prime rib in aluminum foil. The foil will keep the meat from drying out completely.

Step 3

Heat the oven to 250 degrees F. Place the foil-wrapped prime rib on a cookie sheet.

Step 4

Heat the prime rib until it reaches an internal temperature of 165 degrees F. Test temperature with a meat thermometer.
