Preheat the oven to 400°F. Line a baking sheet with foil and place a cooking rack on top.
Pat the chicken breasts dry with paper towels to ensure the skin crisps up.
In a small bowl, combine ½ teaspoon salt, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon ground black pepper, ¼ teaspoon paprika, and ¼ teaspoon chili powder. Rub the spice mixture all over the chicken breasts, making sure the seasoning covers both sides.
In a large skillet, heat ½ cup of avocado oil (or your preferred high-smoke point oil) over medium-high heat until hot.
Carefully place the chicken breasts skin-side down into the hot skillet. Cook for 2 minutes, until the skin is golden and crispy. Flip the chicken breasts over and cook for another 2 minutes on the other side.
Place the seared chicken breasts onto the prepared baking sheet with rack. Drizzle 1 teaspoon of the oil from the skillet onto each chicken breast. Transfer the baking sheet to the preheated oven.
Bake for 45 minutes, or until the internal temperature of the chicken reaches 165°F when measured with a meat thermometer. Remove from oven and add to a plate. Let the chicken sit for 10 minutes before slicing. Serve and enjoy!
