Place the frozen patties in the air fryer. It's ok if you are unable to pull apart multiple frozen patties. Place them in the air fryer while they are still stuck together.
Air fry for 5 minutes on 360 degrees.
Open the air fryer and use a spatula to split up the patties (if necessary).
Brush liquid smoke and Worcestershire sauce onto both sides of each patty.
Sprinkle the spices onto both sides of each patty.
Air fry for an additional 4 minutes on 360 degrees.
Open the air fryer and flip the patties. Air fry for an additional 3-4 minutes (If adding cheese, I like to add it at 3 minutes and then air fry for an additional 1 minute to melt the cheese) or until the burgers reach your desired level of doneness. Use a meat thermometer and check the internal temperature. 125 degrees rare135 degrees medium rare145 degrees for medium155 degrees for medium-well160 degrees for well done.
Serve on buns with your favorite toppings.
You can cook as many burgers as you like and double the serving sizes and ingredients for the rub, etc.
I like to serve my burgers on toasted buns. After cooking the burgers, you can let them toast in the air fryer for a couple of minutes.
If you are using turkey burgers, the cook time should remain the same.
