Air fryers cook by circulating hot air, producing a crisp exterior with minimal added fat. Preheat the air fryer to 375°F (190°C). Form patties slightly thinner than before (about 3/4 inch) so they cook through without burning the outside. Lightly brush or spray patties with oil for better browning.
Place patties in a single layer in the air fryer basket with space around each one. Cook for 8–10 minutes, flipping halfway through. Add cheese in the final 1–2 minutes and re-cover to let it melt.
Air-fried burgers are a convenient, lower-fat option that still deliver a satisfying crust and juicy interior when timed and preheated properly.
