Step 1

Whisk lemon juice, olive oil, Dijon mustard, garlic, salt, and pepper together in a bowl. Set marinade aside.

Step 2

Place chicken thighs into a large resealable plastic bag. Pour marinade over chicken and seal bag, making sure to cover all parts of chicken. Refrigerate for at least 2 hours.

Step 3

Preheat an air fryer to 360 degrees F (175 degrees C).

Step 4

Remove chicken from marinade and pat dry with paper towels. Place chicken pieces in the air fryer basket, cooking in batches if necessary.

Step 5

Fry until chicken is no longer pink at the bone and the juices run clear, 22 to 24 minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C). Squeeze a lemon wedge over each piece upon serving.
