Instructions

  1. Step 1: Preheat oven to 425°F. In a small bowl, mix 4 tbsp softened unsalted butter with 2 tbsp chopped fresh rosemary and 4 minced garlic cloves.
  2. Step 2: Pat dry 6 bone-in, skin-on chicken thighs and season both sides with 1 1/2 tsp sea salt and 1 tsp black pepper. Rub the garlic rosemary butter evenly under and over the skin of each thigh.
  3. Step 3: Heat 1 tbsp olive oil in a large oven-proof skillet over medium-high heat. Place chicken thighs skin-side down and sear for 5 minutes until the skin is golden and crisp.
  4. Step 4: Flip the thighs and transfer the skillet to the preheated oven. Roast for 20-25 minutes until the internal temperature reaches 165°F and juices run clear.
  5. Step 5: Remove from oven, let rest for 5 minutes, then serve the chicken thighs with any pan juices spooned over.
