Beyond Meat recommends thawing burger patties before cooking them for the best taste and texture. However, you can cook frozen Beyond Burgers in the air fryer. You'll need to cook them longer than refrigerated Beyond Burgers. I cook frozen Beyond Burgers in the air fryer at 360°F for 6 minutes then flip them over and cook another 5-6 minutes until they reach an internal temperature of 165°F. The cook time will depend on the make and model of your air fryer.
