Add all of the ingredients EXCEPT the butter and chicken to a large food processor. Blend until smooth.
3-4 cups loosely packed cilantro stems & leaves, rinsed & pat dry, 1 jalapeño*, 6-7 cloves garlic, ¼ cup Greek yogurt or sour cream, 2 Tablespoons olive oil, 2 limes, juiced & zested, 1 Tablespoon honey*, 1 ½ teaspoons Morton kosher salt*, 1 teaspoon cumin
In a small bowl, reserve about 2 Tablespoons of the marinade. Set aside in the fridge.
Add the chicken thighs to a large bowl or zip-top bag. Add all of the remaining marinade to the chicken and toss well. Marinate in the refrigerator for at least 2 hours (or overnight).
8 chicken thighs (about 2.5 pounds*)
Mix together the reserved marinade and the melted butter. Set aside.
2 Tablespoons unsalted butter, melted
Arrange the chicken thighs in a single layer in the air fryer basket. I can usually fit about 4.
Air fry at 380 degrees for 18-22 minutes, flipping halfway through. The internal temperature should be around 170 degrees. Brush cooked chicken with the cilantro lime butter before serving.
