Preheat the air fryer: Set it to 380°F (193°C) for 5 minutes.
A hot basket helps everything crisp up.
Prep the potatoes: Rinse, dry well, and cut into 1-inch chunks. Patting them dry is key for crisp edges.
Season the potatoes: In a large bowl, toss potatoes with 1 tablespoon olive oil, 1 tablespoon ranch seasoning, smoked paprika, half the salt, and pepper. Stir to coat evenly.
Start the potatoes first: Add potatoes to the hot basket in a single layer if possible.
Air fry for 10 minutes, shaking once halfway. This gives them a head start.
Prep the chicken: While potatoes cook, cut chicken into 1.5-inch pieces or leave thighs whole if you prefer. Pat dry.
Toss with remaining 1 tablespoon olive oil, 1 tablespoon ranch seasoning, garlic powder, onion powder, and remaining salt.
Add chicken to the basket: After the potatoes have cooked 10 minutes, shake the basket to move them aside a bit, then add the chicken pieces on top/in between. Don’t pack too tightly; air needs to circulate.
Finish cooking: Air fry at 380°F for 12–15 minutes, shaking the basket every 4–5 minutes. Chicken is done when it reaches 165°F internally and the potatoes are deeply golden.
Optional crisp: For extra color, bump to 400°F for the last 2–3 minutes, watching closely.
Rest and garnish: Let everything rest 3 minutes.
Sprinkle with fresh parsley or chives. Serve with ranch for dipping or a squeeze of lemon to brighten the flavors.
