Pat the chicken dry. Rub with olive oil, Tuscan seasoning, garlic powder, paprika, salt and pepper.
Preheat the air fryer to 400°F. Toss the potatoes with olive oil, rosemary, thyme, salt and pepper.
Air fry the potatoes at 400°F for 10 minutes, shaking halfway.
Push the potatoes to the edges and add the chicken in a single layer. Air fry at 380°F for 6 minutes. Flip the chicken and shake the potatoes.
Toss the bell pepper, zucchini and tomatoes with olive oil, basil, oregano, salt and pepper. Add them to the basket and air fry at 400°F for 6 to 8 minutes, until the chicken reaches 165°F and the veggies are tender.
Rest the chicken 5 minutes, then serve everything together.
