First Step: Prepare Ingredients and Preheat Air Fryer. Gather all ingredients, including ground beef or your preferred protein, seasonings, and buns or alternatives. Preheat your air fryer to 370°F (190°C) for about 5 minutes to ensure an even cooking environment for the patties.

Second Step: Mix and Season the Meat. In a medium bowl, combine the ground beef with salt, black pepper, onion powder, garlic powder, and optionally Worcestershire or barbecue sauce. Mix gently by hand to avoid overworking the meat and maintain tender burgers.

Third Step: Shape Patties. Divide the mixture evenly into four patties, each approximately ½ inch (1.3 cm) thick. Press a small indentation with your thumb into the center of each patty; this helps prevent puffing and ensures even cooking.

Fourth Step: Arrange Patties in Air Fryer Basket. Place the patties in a single layer inside the air fryer basket, keeping space between them to allow hot air to circulate freely for crisp edges. Use parchment liners if desired for easier cleanup and to prevent sticking.

Fifth Step: Cook Patties. Air fry the patties for about 6 minutes, flip them over, and cook for an additional 3 to 5 minutes, or until the internal temperature reaches 160°F (71°C) for ground beef. Check patties early to adjust cooking time as needed based on air fryer model and patty thickness.

Sixth Step: Melt Cheese (If Desired). During the last minute of cooking, add cheese slices to the patties to allow melting. This produces molten, cheesy burgers that are irresistible.

Final Step: Rest, Assemble, and Serve. Remove burgers from the air fryer and let rest for 1 to 2 minutes to redistribute juices. Toast buns in the air fryer for 1-2 minutes if desired. Assemble burgers with chosen toppings and condiments, then serve immediately for the best taste and texture.
