In a large bowl, mix together beef, garlic, and soy sauce. Shape into four equal sized patties. Press your thumb into the center of each patty to form a divot. Season both sides with salt and pepper.
Place patties in air fryer, two at a time, and cook at 375° for 4 minutes per side (for medium doneness). Remove and immediately top with a slice of cheese. Repeat with remaining patties.
Spread bottom buns with mayo, then add lettuce, cheeseburger patties, tomatoes, onions, and top bun. Enjoy!
