How Long to Air Fry Boneless Chicken Thighs

The short answer

Air fry boneless chicken thighs at 375°F for about 18–24 minutes, or at 400°F for about 14–20 minutes. The exact time depends on thickness, starting temperature, and your air fryer. Begin checking early rather than relying on the clock alone. Chicken is ready when the thickest part reaches at least 165°F / 74°C on an instant-read thermometer.

How to arrange the chicken

Pat the thighs dry, season them, and place them in a single layer in the air fryer basket. Leave a little space between pieces so hot air can circulate and the surfaces brown instead of steaming. Work in batches if the basket is crowded. A preheated air fryer can improve browning, but follow your appliance’s instructions if preheating is not recommended.

• Use similarly sized thighs together.
• Avoid stacking or overlapping.
• Start checking the smallest pieces first.

Do you need to flip them?

Flipping is optional, especially in a well-circulating basket. It can help both sides brown more evenly, so turn the thighs halfway through if the underside looks pale or your air fryer has uneven airflow. If you leave them untouched, simply check the temperature near the end of the suggested range and add time in short increments if needed.

Why thighs stay juicy

Boneless thighs contain more natural fat and connective tissue than lean chicken breast, so they are generally more forgiving when cooked. That richness helps them remain juicy while the exterior browns. They can still dry out if they are unusually thin, overcooked, or held in the hot basket for too long, so remove them soon after they reach 165°F.

How to check and serve

Insert the thermometer into the thickest section, approaching from the side if the pieces are thin, and avoid touching the basket. If the reading is below 165°F, return the chicken to the air fryer for 2–3 minutes, then check again. Let the cooked thighs rest for a few minutes before slicing. For leftovers, refrigerate them within 2 hours and use within 3–4 days.
