Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Pat chicken dry with paper towels. In a bowl, mix 2 tbsp olive oil, rosemary, thyme, and garlic. Rub mixture over chicken, season with salt and pepper. Place on a roasting pan and roast for 1 hour, basting every 20 minutes with pan juices until skin is golden and crispy.
  2. Step 2: While chicken roasts, boil potatoes in salted water until tender, about 15 minutes. Drain. In a large pot, melt butter over medium heat. Add milk, salt, and pepper. Stir until butter is fully incorporated and mixture is warm. Add potatoes and mash until smooth and creamy, adding more milk if needed.
  3. Step 3: Once chicken is done, let rest 10 minutes before carving. Serve with mashed potatoes.
