First, let's season the ground beef. Add the onion powder, garlic powder, black pepper, and salt to the beef. Next, add 2 teaspoons of Worcestershire sauce.
Using your bare hands, mix the beef and the seasoning well together. Once done, put in the fridge for 1 hour. I prefer to let the ground beef chill in the fridge so that they will stick together and not fall apart when rolling them into patties.
Once the beef mixture is chilled, take it out from the fridge and separate them into 4 portions. Lightly roll the 4 portions into balls and then flatten them into patties.
Heat the air fryer to 360°F for 5 minutes, then slowly place the beef patties into the air fryer basket. Make sure that you have enough space for the patties. Cook in batches if required.
For medium to medium well-done burgers, I suggest cooking the beef patties for about 15 minutes. Remember to turn the patties halfway through the cooking. Once the patties are cooked, open the air fryer basket and place the cheese slices onto the patties. After that close the basket for one to two minutes to let the heat in the air fryer melt the cheese.
I prefer to melt the cheese this way, instead of cooking them together with the beef patties as the heat would be too much for the cheese and will create a huge mess.
Once the cheese slices melt, take out the patties and place them onto the burger buns. You can add some of your favorite greens to the burger.
You can serve the air fryer hamburgers with some crispy air fryer potato wedges.
