Instructions

1. Step 1: Preheat oven to 425°F (220°C). Rub the whole 4 lb chicken inside and out with 2 tsp salt, 1 tsp black pepper, and 4 tbsp olive oil.
2. Step 2: Stuff the chicken cavity with 1 quartered lemon and 3 sprigs fresh thyme. Tie the legs together with kitchen twine.
3. Step 3: Place the chicken breast-side up on a roasting rack in a roasting pan. Roast for 15 minutes, then reduce heat to 375°F (190°C) and continue roasting for 1 hour 15 minutes, basting occasionally with pan juices, until internal temperature reaches 165°F (74°C).
4. Step 4: While chicken roasts, heat 2 tbsp olive oil in a large skillet over medium heat. Add 4 crushed garlic cloves and 1 large diced yellow onion; sauté for 3 minutes until translucent.
5. Step 5: Add 1 medium diced eggplant, 2 medium diced zucchini, and 1 large diced red bell pepper; cook for 8-10 minutes until vegetables soften.
6. Step 6: Stir in 3 diced tomatoes and 1/4 cup chopped fresh basil leaves; cook for 5 more minutes until the sauce thickens slightly and vegetables are tender.
7. Step 7: Remove chicken from oven and let rest 10 minutes before carving. Serve alongside the ratatouille for a bright, herbaceous meal.
