You only need to cook each side of the turkey burger for a few minutes! The inside should be cooked all the way through and be completely brown with no pink. The internal temperature should reach 165 degrees Fahrenheit. We highly recommend purchasing a meat thermometer to check the temperature to ensure it is safely cooked, but not overcooked and dry. I have used this meat thermometer and have really liked it! I appreciate that it has the temperatures for each type of meat on the thermometer for a quick reference.
