Prepare the Herb Butter: In a mixing bowl, combine softened butter, minced garlic, rosemary, thyme, sage, lemon zest, salt, and pepper. Mix until well blended.
Season the Turkey: Gently lift the skin of the turkey with your fingers, starting at the neck end. Carefully spread the herb butter mixture underneath the skin of the turkey, covering as much of the breast and thighs as possible. Use any leftover butter to rub all over the exterior of the turkey.
Stuff the Turkey: Inside the cavity of the turkey, place the quartered onion, halved lemon, and a handful of fresh herbs. This will infuse moisture and flavor during cooking.
Preheat the Air Fryer: Set your air fryer to 350.0 and preheat for about 5 minutes.
Prepare for Cooking: Lightly grease the air fryer basket with cooking spray or oil. Place the turkey breast-side down in the basket. This will help keep the breast juicy.
Cooking Time: Air fry the turkey at 350.0 for 30 minutes. After 30 minutes, carefully flip the turkey breast-side up.
Continue Cooking: Air fry for an additional 60.0 to 70.0 minutes, or until the internal temperature reaches 165.0 when checked at the thickest part of the thigh. Baste the turkey with pan juices halfway through this cooking time for extra flavor and moisture.
Rest the Turkey: Once done, remove the turkey carefully from the air fryer and let it rest for at least 20 minutes before carving. This allows for the juices to redistribute, resulting in a juicier turkey.
Serve: Carve the turkey and serve it dressed up with your favorite sides and a drizzle of the herb-infused pan juices. Enjoy your delightful Herb Butter Turkey with family and friends!
Notes
Let the turkey rest before carving for best results.
