01 - In a large bowl, combine ground beef, salt, pepper, garlic powder, onion powder, Worcestershire sauce, and optional breadcrumbs and egg if desired. Mix gently until just combined—avoid overmixing for tender patties.
02 - Divide the mixture into 4 equal portions and shape each into a patty about 3/4-inch thick. Use your thumb to make a small indentation in the center of each patty to prevent puffing during cooking.
03 - Preheat the air fryer to 375°F for 3 minutes before cooking.
04 - Arrange the patties in the air fryer basket in a single layer, leaving a little space between them for proper air circulation.
05 - Air fry for 10-12 minutes, flipping halfway through, until patties reach your desired doneness (160°F internal temperature for medium-well).
06 - If using cheese, add a slice to each patty during the last minute of cooking to allow melting.
07 - Remove patties from the air fryer and let rest for 2 minutes to allow juices to redistribute.
08 - Assemble burgers with buns and desired toppings. Serve immediately.
