These delicious Air Fryer Hamburgers are just as good as grilled burgers and can be on your table in a jiffy, complete with all your favorite toppings.
In a large bowl, combine ground beef, onion powder, garlic, salt, pepper and liquid smoke (optional). Do not overmix. Divide the beef into 4 equal portions. Use hands to lightly form into round patties. Do not press hard. Handling the patties lightly will ensure soft, juicy burgers. Use your thumb to press a dome in the middle of the burger so that it will cook evenly and prevent it from shrinking.
Spray the air fryer basket with cooking spray oil. Place the patties into the air fryer for 5 minutes. Then, carefully flip the burgers over and let it cook for an additional 3-5 minutes or until the internal temperature is 160°F. If you are using cheese, add it on top of the patties and heat it for an additonal 30 seconds.
