Step 1

Preheat the air fryer to 400℉ (if your model allows for pre-heating).

Step 2

In a mixing bowl, combine the ground beef, onion soup mix, Worcestershire sauce, salt and pepper with clean hands. Mix well.

Step 3

Divide the mixture into 8 equal parts and form into thin patties.

Step 4

Cut each slice of American cheese into quarters and stack the pieces on top of each other.

Step 5

Place one stack of cheese in the center half of the patties, leaving a little space around the edges.

Step 6

Top each of the cheese-covered patties with another half of the patties and pinch the edges together to seal.

Step 7

Spray the inside of the air fryer with an oil spray and place the burgers in the air fryer basket. Cook 10 to 12 minutes, or until cooked through.

Step 8

While the burgers are cooking, make the homemade burger sauce by combing all the sauce ingredients in a small bowl and mixing well.

Step 9

Assemble the burgers with the buns and toppings of your choice and burger sauce.
