Ingredients

Instructions

  1. Step 1: Preheat your oven to 425°F (220°C). Pat dry 4 bone-in, skin-on chicken thighs with paper towels to ensure crispy skin.
  2. Step 2: In a small bowl, whisk together 4 tbsp melted unsalted butter, 4 minced garlic cloves, 1 tbsp chopped fresh rosemary, 1 tsp sea salt, and 1/2 tsp black pepper.
  3. Step 3: Rub the chicken thighs all over with 1 tbsp olive oil, then brush the garlic butter mixture evenly over the skin and under the thighs.
  4. Step 4: Arrange the thighs skin-side up on a rimmed baking sheet lined with foil. Roast in the oven for 35-40 minutes until the skin is golden brown and the internal temperature reaches 165°F (74°C).
  5. Step 5: Let the chicken rest for 5 minutes before serving to retain juiciness.
