Place frozen burger patties in a single layer in the air fryer basket.
Cook for 12–15 minutes depending on thickness.
Flip the burgers halfway through cooking (around 6–7 minutes).
Season with salt, pepper, and garlic powder after a few minutes of cooking.
Add cheese slices during the last 1–2 minutes if making cheeseburgers.
Check that the internal temperature reaches 160°F, then let burgers rest briefly before serving.
Notes
Flip burgers halfway through for even cooking. Season after a few minutes so it sticks better. Add cheese during the last 1–2 minutes if desired. Always ensure internal temperature reaches 160°F for safe consumption.
