Prepare the Marinade. In a bowl, combine chopped cilantro, lime juice, olive oil, minced garlic, salt, and pepper. For a spicy kick, add a pinch of red pepper flakes.
Marinate the Chicken. Place the chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring it's evenly coated. Marinate in the refrigerator for at least 30 minutes, allowing the flavors to meld.
Preheat the Air Fryer. Preheat your air fryer to 375°F for 5 minutes.
Air Fry the Chicken. Once the chicken has marinated, remove it from the fridge and shake off any excess marinade. Place the chicken breasts in the air fryer basket in a single layer, leaving space between each piece for optimal air circulation.
Cook Until Golden Brown. Air fry the chicken breasts for 15-20 minutes, flipping halfway through, until they are golden brown and cooked through. The internal temperature should reach 165°F.
Serve and Enjoy. Once cooked, remove the chicken from the air fryer and let it rest for a few minutes before slicing.
