Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Season chicken thighs with salt and pepper, then rub with 2 tbsp butter and 1 tbsp rosemary. Place on a roasting pan and roast for 45 minutes, basting with pan juices every 15 minutes.
  2. Step 2: While chicken roasts, melt 2 tbsp butter in a saucepan over medium heat. Add 6 minced garlic cloves and sauté for 2 minutes until fragrant. Stir in 2 cups mashed potatoes, 2 tbsp milk, 1 tsp salt, and 1/2 tsp black pepper. Cook until creamy and smooth, about 5 minutes.
  3. Step 3: Transfer chicken to a serving platter, cover with foil, and let rest for 10 minutes. Serve with garlic mashed potatoes and additional fresh thyme garnish.
