Prep the chicken: Pat the chicken dry with paper towels. If using breasts, pound to an even thickness (about 3/4 inch) for even cooking.
Mix the rub: In a small bowl, combine salt, pepper, smoked paprika, garlic powder, onion powder, and chili powder or cayenne if using.
Season: Toss the chicken with olive oil, then sprinkle on the spice mix, coating all sides. Press gently so it sticks.
Preheat the air fryer: Set to 380°F (193°C) for 3–5 minutes.
Lightly spray the basket with cooking spray.
First cook: Arrange chicken in a single layer with space between pieces. Air fry for 8–10 minutes for breasts (thighs may need 10–12), flipping halfway. You’re aiming for about 150–155°F internal temp at this stage.
Make the BBQ glaze: Stir the BBQ sauce with apple cider vinegar or lemon juice.
This thins it slightly so it coats well and doesn’t scorch.
Glaze and finish: Brush the chicken generously with the BBQ sauce. Air fry 2–4 more minutes, or until the thickest part hits 165°F and the sauce looks glossy and a little sticky.
Rest: Let the chicken rest on a plate for 5 minutes. This keeps it juicy when you slice it.
Slice or shred: For meal prep, slice across the grain or shred with two forks.
Toss with a spoonful of extra BBQ sauce if you like it saucy.
Build your boxes: Divide the chicken among meal prep containers with sides such as rice or quinoa, steamed or roasted veggies, and a crunchy slaw or salad.
