Frozen hamburger patties are quick and easy to make. The cooking time will vary based on how large, thick, and your cooking preference, but it also depends on the type of grill.
It is not necessary to defrost the frozen patties before cooking. For a rare burger, it takes around 10 minutes, and for a well-done burger, it takes about 20 minutes.
Preheat the grill to 375 degrees Fahrenheit and flip the burgers every five minutes. The patties should be a minimum of 160 degrees internal temperature.
