Instructions

1. Step 1: Preheat oven to 425°F. In a small bowl, whisk together 3 tbsp olive oil, juice of 1 lemon, 4 minced garlic cloves, 1 1/2 tsp salt, and 1 tsp black pepper to create a lemon-thyme marinade.
2. Step 2: Pat dry 1 whole (4 lb) chicken and rub the marinade all over the chicken skin and inside the cavity. Stuff the cavity with 6 fresh thyme sprigs and 1 sliced lemon.
3. Step 3: Place the chicken breast-side up on a roasting pan. Surround the chicken with 2 chopped zucchini, 2 chopped yellow squash, 1 chopped red bell pepper, 1 cup cherry tomatoes, and 1 chopped red onion. Drizzle vegetables with any remaining marinade.
4. Step 4: Roast in the preheated oven for 1 hour 15 minutes, basting the chicken and stirring vegetables halfway through. The chicken is done when the internal temperature reaches 165°F and juices run clear.
5. Step 5: Remove chicken from oven and let rest 10 minutes before carving. Serve the roast chicken alongside the tender, caramelized summer vegetables for a hearty seasonal dinner.
