Add the beef to a large bowl along with the salt, pepper, Worcestershire sauce, mustard, paprika, garlic, onion, eggs and breadcrumbs.
Mix well with your hands just until combined and all the ingredients are distributed evenly throughout the mixture.
Divide the mixture into 6 balls that are exactly the same size. Use a burger press to form the burgers into a patty shape, or use your hands to pack the burgers into evenly shaped patties. Place a small divot in the middle of one side of each of the burgers to help them keep their shape while cooking.
Chill the patties in the fridge for about 30 minutes before air frying them.
Preheat your air fryer to 200℃ (400℉). Place the burgers in the air fryer in a single layer - you might have to cook in batches.
Air fry at 200℃ (400℉) for 6 minutes. Flip and air fry for another 6-8 minutes depending on your preferred doneness. If you want to make cheeseburgers, open your air fryer one minute before the cooking time is done and add a slice of cheddar cheese on top of each of the burger patties. Cook for one more minute.
Remove the burgers from the heat and let them sit for about 3-5 minutes before serving. This helps them stay juicy and prevents them from falling apart.
Serve on toasted buns with lettuce, tomatoes, cheese, onions and our Easy Homemade Burger Sauce.
