Instructions

  1. Step 1: Preheat the oven to 425°F (220°C). Peel 8 whole garlic cloves and toss them with 2 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper in a bowl until evenly coated.
  2. Step 2: Spread the garlic cloves on a baking sheet and roast for 15 minutes until golden and fragrant.
  3. Step 3: Meanwhile, pat dry 6 bone-in chicken thighs with paper towels. Rub each thigh all over with 3 tbsp English mustard.
  4. Step 4: Place the mustard-coated chicken thighs on a baking tray, nestle the roasted garlic cloves and 2 fresh rosemary sprigs around them.
  5. Step 5: Roast the chicken in the preheated oven for 30-35 minutes until the internal temperature reaches 165°F and the skin is golden and slightly crisp.
  6. Step 6: Let the chicken rest for 5 minutes before serving, allowing the roasted garlic flavor to infuse the meat.
