Pierce the chicken thighs all over with a fork. This'll allow the marinade to penetrate the meat and infuse it with maximum flavor.
Make the marinade. Combine the chopped cilantro, lime juice, olive oil, minced garlic, ground cumin, paprika, salt, and black pepper in a mixing bowl. Mix well.
Marinate the chicken. Add the chicken thighs to the marinade, ensuring they are fully submerged. Allow the chicken to marinate for a minimum of 30 minutes, but marinate it for 24 hours for the best flavor.
Preheat your air fryer to 400ºF (204ºC) for 5 minutes.
After marinating, take the chicken thighs out of the marinade and place the chicken thighs in the air fryer. Arrange them in a single layer, do not overcrowd. If your air fryer is small, you might need to cook the chicken in batches.
Air fry the chicken thighs at 400ºF (204ºC) for 12 - 15 minutes. Then, flip the chicken thighs halfway.
Once the chicken thighs are cooked, let them rest for 5 minutes before serving.
Serve your delicious air fried boneless skinless chicken thighs with your favorite sides like rice, salad, or grilled vegetables. Enjoy your easy and flavorful meal!
