Prep the air fryer. Preheat your air fryer to 375°F (190°C) for 3–5 minutes. A preheated basket helps the burgers brown and release cleanly.

Mix the burger base. In a large bowl, combine ground turkey, 2 tablespoons of the BBQ sauce (reserve the rest for glazing), grated onion, egg, breadcrumbs, Worcestershire, smoked paprika, garlic powder, salt, and pepper. Stir just until combined.

Shape the patties. Divide the mixture into 4 equal portions. With damp hands, form patties about 1/2 inch thick. Make a small thumb indent in the center of each to prevent doming.

Chill briefly. Place patties on a plate and chill for 10–15 minutes. This helps them firm up and hold together in the air fryer.

Prep the basket. Lightly spray or brush the air fryer basket with oil. Avoid heavy oiling, which can cause smoking.

Cook the first side. Arrange patties in a single layer with a little space between them. Air fry at 375°F (190°C) for 6 minutes.

Flip and glaze. Flip the patties carefully. Brush the tops with a thin layer of the remaining BBQ sauce. Air fry for another 5–7 minutes, or until the internal temperature reaches 165°F (74°C).

Add cheese (optional). If using cheese, add a slice to each patty during the last 1 minute to melt.

Rest and build. Let burgers rest for 3 minutes. Toast buns if you like, then stack burgers with your favorite toppings. Add an extra swipe of BBQ sauce for good measure.
