Ingredients

Instructions

  1. Step 1: Preheat the oven to 250°F (120°C). Trim any excess fat or loose skin from 4 bone-in skin-on chicken thighs using a sharp knife. Pat dry with paper towels.
  2. Step 2: In a small bowl, combine 3 tbsp olive oil, 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tsp salt, and 1/2 tsp black pepper.
  3. Step 3: Rub the seasoned olive oil mixture all over the chicken thighs, ensuring the seasoning reaches under the skin for maximum flavor.
  4. Step 4: Place the chicken thighs skin side up on a wire rack over a baking sheet to allow air circulation. Roast in the oven at 250°F for 45 minutes.
  5. Step 5: Increase the oven temperature to 425°F (220°C) and continue roasting the chicken thighs for an additional 20 minutes until the skin is golden brown and crispy, and internal temperature reaches 165°F (74°C).
  6. Step 6: Remove from the oven and let rest for 5 minutes before serving to allow juices to redistribute.
