Instructions

  1. Step 1: Preheat oven to 425°F. Zest and juice 1 large lemon. In a small bowl, combine 3 tbsp olive oil, lemon zest, 2 tsp salt, 1 tsp black pepper, 6 minced garlic cloves, and 4 fresh thyme sprigs stripped of leaves.
  2. Step 2: Rub the lemon-thyme mixture all over 6 bone-in chicken thighs, placing them skin-side up on a rimmed baking sheet. Pour the lemon juice over the chicken.
  3. Step 3: Roast the chicken in the preheated oven for 35-40 minutes until the skin is golden and crisp and the internal temperature reaches 165°F.
  4. Step 4: While chicken roasts, peel and cut 2 lbs russet potatoes into 2-inch chunks. Place in a large pot and cover with cold water. Bring to a boil and cook for 15-20 minutes until tender.
  5. Step 5: Drain potatoes and mash with 4 tbsp unsalted butter, 1/2 cup warm milk, and a pinch of salt until smooth and creamy. Serve the roasted chicken thighs alongside the garlic mashed potatoes.
