Instructions

Step 1: Preheat oven to 425°F. In a large roasting pan, toss 1 medium diced zucchini, 1 medium diced yellow summer squash, 1 small diced eggplant, 1 1/2 cups halved cherry tomatoes, 2 minced garlic cloves, 1 tbsp olive oil, 3/4 tsp salt, and 1/3 tsp black pepper. Spread evenly.
Step 2: Arrange 6 bone-in chicken thighs skin side up on top of the vegetables. Tuck 6 fresh thyme sprigs and 1 sliced lemon around the chicken. Drizzle 2 tbsp olive oil over chicken and vegetables, then season chicken with 3/4 tsp salt and 2/3 tsp black pepper.
Step 3: Roast uncovered for 35-40 minutes until the chicken skin is golden and internal temperature reaches 165°F, and vegetables are tender.
Step 4: Remove from oven and let rest for 5 minutes. Serve chicken thighs alongside the roasted summer vegetable ratatouille, spooning pan juices over the top.
