Gather all ingredients and preheat an air fryer to 400 degrees F (200 degrees C).

Pat chicken thighs dry with a paper towel and brush skins with olive oil. Place chicken thighs, skin-side down, in a single layer on a plate.

Combine smoked paprika, garlic powder, salt, and pepper in a bowl. Sprinkle 1/2 of the seasoning mixture evenly over thighs. Turn thighs over and evenly sprinkle with remaining seasoning. Arrange thighs, skin-side up, in a single layer in the air fryer basket.

Cook in the preheated air fryer until thighs are brown and the juices run clear, about 18 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).

Serve and enjoy!
