Instructions

Step 1: Preheat oven to 425°F. Pat dry 4 pounds whole chicken. Stuff cavity with 2 rosemary sprigs and 1 lemon half. Rub the chicken all over with 3 tbsp olive oil, 6 minced garlic cloves, 1 tsp black pepper, and 1 tsp kosher salt, and place 2 remaining rosemary sprigs on top.
Step 2: Place chicken breast-side up in a roasting pan and roast for 1 hour 15 minutes or until internal temperature reaches 165°F, basting occasionally with pan juices.
Step 3: While chicken roasts, boil 1.5 pounds small Yukon gold potatoes in salted water for 15 minutes until tender. Drain and place on a baking sheet; gently smash each potato with the bottom of a glass.
Step 4: Drizzle smashed potatoes with 2 tbsp melted unsalted butter, sprinkle with 1 tsp kosher salt and 2 tbsp chopped fresh parsley, and roast in the oven alongside the chicken for the last 25 minutes until golden and crispy.
Step 5: Let chicken rest 10 minutes before carving and serve with garlic smashed potatoes.
