Instructions

  1. Step 1: In a small bowl, whisk together 1/4 cup fresh lemon juice, 1/4 cup olive oil, 2 tbsp chopped fresh oregano, 5 minced garlic cloves, 1 tbsp salt, and 1 tsp black pepper to make a marinade.
  2. Step 2: Place the 4 lb whole chicken in a large roasting pan and pour the marinade evenly over it, rubbing under the skin and inside the cavity. Let marinate for at least 1 hour or overnight in the refrigerator.
  3. Step 3: Preheat oven to 325°F.
  4. Step 4: Toss 1.5 lbs halved baby potatoes with 1 tbsp chopped fresh rosemary and a drizzle of olive oil, then spread around the chicken in the roasting pan.
  5. Step 5: Roast the chicken and potatoes for 2 to 2.5 hours, basting occasionally with pan juices, until the internal temperature of the chicken reaches 165°F and the potatoes are tender and golden.
  6. Step 6: Remove chicken from oven and let rest for 10 minutes before carving. Serve with the roasted potatoes and pan juices.
