Step 1: Preheat your air fryer to 400°F (200°C).
Step 2: In a large bowl, toss the cubed potatoes with 1 tablespoon of olive oil and half of the salt, pepper, paprika, garlic powder, and onion powder.
Step 3: Pat the chicken thighs dry with paper towels. Rub the remaining olive oil and spices all over the chicken, ensuring the skin is well-coated.
Step 4: Place the chicken thighs in the air fryer basket, skin side up. Arrange the potatoes around the chicken in a single layer.
Step 5: Cook for 20-25 minutes. At the 12-minute mark, carefully shake the basket or use tongs to flip the potatoes to ensure even browning.
Step 6: Check the chicken with a meat thermometer to ensure it has reached an internal temperature of 165°F (74°C). If the potatoes need more crisping, remove the chicken and cook potatoes for an additional 2-3 minutes.
Step 7: Garnish with fresh parsley and serve immediately.
