1. Place the frozen burgers in a single layer in the air fryer basket.

2. Cook the burgers at 180°C (350°F) for 12-15 minutes, depending on their thickness and type.

3. Open the air fryer around the 6-7 minute mark and carefully flip the burgers to ensure even browning on both sides. Resume cooking for the remaining time.

4. If you want to add cheese, lay a cheese slice on the burgers about 1 minute before the end of the cooking time. If you prefer toasted burger baps, add them to the air fryer basket now.

5. Assemble and add any favourite burger sauces
