Pat the chicken thighs dry with a paper towel and loosen the skin away from the meat.
Season the chicken thighs on both sides with salt and pepper.
In a small bowl, combine the olive oil, softened butter, garlic, and rosemary. Rub the mixture over each chicken thigh, making sure to stuff a little underneath the skin of each thigh (that will help the skin get crispy and keep the thigh moist).
Place the chicken thighs, skin side up, in the center of the sheet pan. Cook for 10 minutes while you prepare the vegetables.
Vegetables
Combine the sweet potatoes, olive oil, and garlic in a small bowl.
Spread the potatoes around the chicken thighs, making sure to place them all in an even layer.
Bake for 15 minutes.
Turn the sweet potatoes to the opposite side and add the apple slices to the pan. Cook for an additional 5 minutes, or until the chicken registers 165F on an instant read thermometer.
Serve immediately. Store any leftovers in an airtight container in the fridge for up to two days.
Notes
I like chicken thighs because they have more flavor and they stay a bit juicer than breasts-- but feel free to use what you have on hand.
The olive oil will help the chicken and vegetables crisp in the oven.
The butter will help the chicken brown and keep it moist.
The garlic is going to add great flavor. If you don’t have fresh garlic, substitute ¼ teaspoon garlic powder per clove.
Rosemary adds a nice fresh, herby-ness! If you don’t have fresh rosemary, you can substitute sage or thyme-- but I highly recommend using fresh herbs in this recipe.
I like the sweet potatoes in this recipe because they’re a bit sturdier and have a nice earthy sweetness. Feel free to substitute Yukon gold or red potatoes if you prefer.
I use granny smith apples because they add a nice tartness and hold their shape in the oven. Feel free to use whatever apples you have on hand.
