To reheat lobster, it should be cooked in aluminum foil in an oven for 5 to 10 minutes at 350 degrees Fahrenheit, according to Jordan Lobster Farms. The lobster itself should be wrapped in foil and placed on a cookie sheet to prevent messes and drips.
Other ways to reheat or reuse lobster include using it in recipes that require lobster. Some popular lobster recipes include lobster bisque, lobster salad and lobster cakes. When initially prepared, cooking methods for lobster include broiling, boiling and grilling. Boiling is perhaps the easiest option. A 2-pound lobster takes approximately 15 minutes to boil, while a 3-pound lobster should be boiled for 25 minutes.
