In a medium-sized mixing bowl, add the ground beef, burger seasoning, and Worcestershire sauce. Use your hands to gently mix everything together until just combined. Be careful not to overwork the meat—this helps keep the burgers tender.
Divide the mixture into four equal portions. Using your hands, form each portion into a thin, round patty that’s slightly larger than your burger buns. The patties will shrink and thicken during cooking, so it’s okay if they look a little oversized.
Set your air fryer to the air fry setting at 375°F. Allow it to preheat fully—this ensures the burgers sear on the outside and stay juicy on the inside.
Place the patties in a single layer in the air fryer basket, leaving space between each one. You may need to cook in batches depending on the size of your air fryer. Cook for 7 to 9 minutes. For medium doneness, check around 7 minutes. For well done, go closer to 9. There’s no need to flip—the air fryer circulates heat evenly on both sides.
Carefully remove the cooked patties and place them on a plate lined with a paper towel to absorb any extra grease. Immediately top each patty with a slice of your favorite cheese and let them rest for 2 to 3 minutes so the cheese can melt and the juices can redistribute.
Toast your buns (optional but highly recommended) with a bit of butter either in the air fryer or on a skillet. Place each patty on a bun and load up with your favorite toppings—lettuce, tomato, onion, pickles, and don’t forget the Big Mac Sauce!
