Instructions

Step 1: Preheat oven to 425°F. In a small bowl, mix 4 tbsp softened unsalted butter, 2 tbsp finely chopped fresh rosemary, and 4 minced garlic cloves until well combined.
Step 2: Pat dry 6 bone-in chicken thighs with skin on. Season both sides evenly with 2 tsp salt and 1 tsp black pepper.
Step 3: Rub the rosemary garlic butter mixture all over and under the skin of each chicken thigh. Drizzle 1 tbsp olive oil over the thighs and arrange them skin-side up on a baking sheet.
Step 4: Roast in the preheated oven for 35-40 minutes until the skin is golden brown and crispy and the internal temperature reaches 165°F.
Step 5: Let rest for 5 minutes before serving to retain juices and maximize flavor.
