Instructions

  1. Step 1: Preheat your oven to 425°F. Pat dry 6 bone-in, skin-on chicken thighs to ensure crispy skin.
  2. Step 2: In a small bowl, combine 2 tbsp extra virgin olive oil, 2 tbsp chopped fresh rosemary, 4 minced garlic cloves, 1 tsp sea salt, and 1/2 tsp black pepper to create a flavorful herb paste.
  3. Step 3: Rub this mixture evenly over each chicken thigh, making sure to get under the skin for maximum flavor.
  4. Step 4: Arrange the chicken thighs skin side up on a rimmed baking sheet lined with parchment paper and roast in the preheated oven for 35-40 minutes until the skin is golden and crispy and the internal temperature reaches 165°F.
  5. Step 5: Let the chicken rest for 5 minutes before serving to seal in the juices.
