Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Rub 4 bone-in chicken thighs with 3 tbsp olive oil, 1 1/2 tsp salt, 1 tsp black pepper, and 4 minced garlic cloves. Arrange chicken in a baking dish, tuck 6 sprigs fresh thyme and 1 sliced lemon around and under pieces.
  2. Step 2: Roast chicken for 30-35 minutes until skin is golden and internal temperature reaches 165°F, basting occasionally with pan juices.
  3. Step 3: Meanwhile, peel and cut 2 large russet potatoes into 1-inch cubes. Place in a pot of cold salted water and bring to a boil. Cook for 15-18 minutes until tender.
  4. Step 4: Drain potatoes and mash with 4 tbsp butter and 1/2 cup whole milk until smooth and creamy. Stir in 2 tbsp chopped fresh parsley and season with salt to taste.
  5. Step 5: Serve roasted lemon-thyme chicken atop a bed of garlic mashed potatoes, spooning pan juices over the chicken for extra flavor.
