Prep the chicken: Pat the chicken pieces dry with paper towels. Dry chicken browns better and holds seasoning.
Season: In a bowl, toss chicken with olive oil, smoked paprika, garlic powder, onion powder, salt, pepper, and optional cayenne.
Stir until the pieces are evenly coated.
Add a little sauce: Mix in 2–3 tablespoons of BBQ sauce to lightly coat the chicken. This helps build a base layer of flavor without making the bites soggy.
Preheat the air fryer: Set to 390–400°F (200°C) for 3–5 minutes. A hot basket gives you better browning.
Arrange in the basket: Place chicken in a single layer with a bit of space between pieces.
Work in batches if needed. Don’t overcrowd.
Cook the first side: Air fry for 6–7 minutes. Shake the basket or flip the bites halfway through to promote even cooking.
Check doneness: Chicken is done at an internal temperature of 165°F (74°C). If not there yet, cook 1–2 minutes more.
Glaze: Transfer cooked bites to a bowl and toss with 1/4–1/3 cup of BBQ sauce until glossy.
For extra caramelization, return them to the air fryer for 1–2 minutes.
Finish and serve: Garnish with parsley, green onions, or sesame seeds if you like. Serve hot with extra sauce for dipping.
