Ingredients

  • 4 tablespoons extra virgin olive oil

Instructions

  • Preheat the oven to 375°F (190°C).

  • In an oven-safe casserole dish, arrange the tomato, zucchini, and squash in rows, alternating a slice of each color to create layers with color contrast.
  • Cover with the sautéed mixture of onions, garlic, and rosemary.
  • Cover with aluminum foil and bake for 45 minutes.
  • Uncover and bake for 15 more minutes until the surface browns and the liquids are reduced.
