To cook frozen patties, preheat your air fryer to 390 degrees Fahrenheit, and cook the patties between eight and 12 minutes, checking their temperature about eight minutes in.
Look for an internal temperature of at least 120 degrees Fahrenheit or 135 degrees if you prefer your burgers well-done. Let the patties rest for a few minutes before serving.
Note that frozen patties won't absorb seasonings as well as thawed patties, so you'll have to add more seasoning than normal during and after cooking to ensure they're flavorful.
