Preheat the air fryer to 390–400°F (200–205°C) for 3–5 minutes.
A hot basket helps you get that light char.
Prep the chicken and veggies. Pat the chicken dry with paper towels and cut into even 1-inch pieces. Chop the vegetables to roughly the same size so they cook evenly.
Season in a large bowl.
Add chicken and veggies. Drizzle with olive oil. Sprinkle on garlic powder, smoked paprika, Italian seasoning, onion powder, salt, and pepper.
Toss until everything is well coated and glossy.
Load the basket in a single layer. Don’t pile it high. If your air fryer is small, cook in two batches. Crowding leads to steaming, not crisping.
Air fry for 10 minutes.
Shake the basket halfway through to move pieces around for even browning.
Check doneness and finish. Continue cooking 3–6 more minutes, shaking once, until the chicken reaches 165°F (74°C) internally and the veggies are tender with browned edges.
Brighten it up. Squeeze fresh lemon over the top, or sprinkle parsley and Parmesan.
Taste and adjust salt and pepper.
Serve over rice, quinoa, cauliflower rice, or with warm pita. A quick yogurt or tahini sauce on the side is great if you want something creamy.
