Pre-heat your oven to 400 F and set the rack to the lower mid position. In a small bowl, mix your room-temperature butter with minced garlic, rosemary, thyme, and oregano. You’ll be shocked at how flavorful this compound butter becomes!
Pat your whole chicken dry with paper towels, spray with avocado oil, and sprinkle on salt, pepper, garlic powder, onion powder, and smoked paprika.
Gently peel back the skin of the chicken breasts and stuff half the butter mixture under the skin on each side. This infuses the meat with buttery flavor as the chicken cooks.
Place remaining herbs, plus the apple and onion (if using), inside the chicken cavity. They help the chicken cook evenly and add amazing flavor.
Microwave the remaining herb butter for 15–20 seconds until melted, then pour it over the top of the skin. I also like to add an additional sprinkle of smoked paprika on top for color!
Place breast-side up in a roasting pan or cast iron skillet and roast for 1 hour to 1 hour 20 minutes, or until the thickest part of the thigh reaches 165°F on an instant-read thermometer. Let rest 10–15 minutes before slicing!
