Preheat the air fryer: Set to 375°F (190°C) for 3–5 minutes so it’s hot and ready. Preheating helps the burgers brown nicely.
Mix the burger base: In a bowl, combine ground turkey, onion, garlic, breadcrumbs, Worcestershire, Dijon, smoked paprika, cumin, salt, and pepper. Stir gently until just combined. Don’t overmix or the burgers can turn dense.
Form patties: Divide into 4 equal portions and shape into 1/2-inch thick patties. Press a small thumbprint in the center of each to help them cook evenly and stay flat.
Oil lightly: Brush or spray both sides with a thin layer of olive oil. This promotes browning and prevents sticking.
Air fry: Place patties in a single layer in the basket, leaving space between them. Cook for 6–7 minutes.
Flip and finish: Flip the patties and cook another 5–7 minutes, until the internal temperature reaches 165°F (74°C). Thicker patties may need an extra minute.
Toast buns (optional): Remove burgers and quickly toast buns in the air fryer at 350°F (175°C) for 1–2 minutes.
Assemble: Add burgers to buns with lettuce, tomato, onion, and your favorite sauce. For a lighter option, use lettuce wraps or serve over a salad.
Serve: Pair with sweet potato fries, a simple slaw, or roasted veggies for a balanced meal.
