To reheat a whole lobster in the oven, place it belly-side up on a large piece of heavy-duty foil and spread butter on top. Wrap the lobster in the foil, place it on a baking sheet, and heat it at 350 degrees Fahrenheit for five to ten minutes, or until the internal temperature reads 145 degrees F on a thermometer.

Wrap a lobster in its shell using damp paper towels and heat it in the microwave in one- or two-minute increments, until the internal temperature reaches 165 degrees Fahrenheit. Use a thermometer to measure the temperature, since cold spots in the lobster can contain bacteria that cause illness.

After removing the lobster meat from its shell, heat a small amount of stock or broth of your choice in a pan or skillet until it simmers. Add the lobster meat and sauté for about 10 minutes until warm; then add a little bit of butter for flavor and cook until the internal temperature reaches 145 degrees F.

To heat up pieces of lobster meat, turn your grill to high and add olive oil, salt, and pepper to the meat and warm it all the way through. For a whole lobster in the shell, lay it on the grill belly-side up and heat until it reaches an internal temperature of 145 degrees F, and do not flip it during the process.
