In a large bowl, add chicken thighs, olive oil, lemon pepper seasoning, garlic powder, smoked paprika, and salt. Marinate for 5-10 mins.
Preheat air fryer to 425F for a few mins. Add chicken thighs (don’t overcrowd and cook in batches as needed) and air fry for 11-14 mins until browned and cooked through (internal temperature should be 165F or more)
While the chicken is cooking, combine melted butter, lemon juice, lemon zest, lemon pepper seasoning, smoked paprika, salt, and parsley. Set aside.
Once chicken is done, remove chicken from air fryer then brush the lemon pepper butter all over the chicken while the chicken is still hot. Serve chicken with fluffy white rice, veggies, and extra lemon pepper butter.
