Instructions

Step 1: Preheat oven to 375°F. In a small bowl, mix 1/4 cup olive oil with 3 minced garlic cloves, 2 tsp fresh thyme leaves, 1 1/2 tsp salt, and 1 tsp black pepper.
Step 2: Lightly grease a 9x13-inch baking dish. Arrange alternating slices of 1 medium eggplant, 2 medium zucchini, 2 medium yellow squash, and 4 medium roma tomatoes upright in the dish, packing tightly.
Step 3: Drizzle the garlic-herb olive oil evenly over the arranged vegetables.
Step 4: Cover the dish with foil and bake for 35 minutes. Remove foil and sprinkle 1/3 cup grated Parmesan cheese on top. Continue baking uncovered for 15 minutes until vegetables are tender and cheese is golden.
