Mix together the ground beef, minced garlic, salt, and pepper with your hands.
Form ground beef into 4 patties and press them down with the back of a pie plate to make them evenly flat.
Place hamburgers in a single layer inside the air fryer.
Cook for 8-12 minutes, flipping halfway through cooking for medium-well hamburgers.*
Carefully remove hamburgers from the air fryer,** place onto hamburger buns (if using), and add desired toppings.

Notes
*thicker hamburgers may take longer to cook if not pressed down properly** if making cheeseburgers, place a piece of cheese on each burger in the air fryer, turn the air fryer off, and let the burgers sit in the air fryer for 1 to 2 minutes until melted
