Prep the air fryer: Preheat to 375°F (190°C) for 3–5 minutes. Lightly oil the basket or use a parchment liner with holes.
Mix the patties: In a bowl, combine ground chicken, breadcrumbs, grated onion, garlic, parsley, Dijon, paprika, salt, pepper, Worcestershire, and olive oil.
Stir gently just until combined. Don’t overmix or the burgers can turn dense.
Form the patties: Divide into 4 equal portions. With damp hands, shape into 1/2-inch thick patties. Press a small dimple in the center of each to prevent doming.
Cook: Place patties in a single layer in the basket.
Air fry for 10–12 minutes, flipping at the 6-minute mark. Cook to 165°F (74°C) internal temperature.
Toast the buns: In the last 2 minutes, split buns and add to the air fryer (cut side up) until lightly toasted.
Rest and build: Let patties rest 2 minutes. Stack on buns with your favorite toppings and sauce.
Serve: Pair with sweet potato fries, a salad, or crunchy slaw for balance.
