Homemade ratatouille loaded with eggplant, zucchini, and tomatoes tossed in garlicky onions, roasted until tender, then sprinkled with fresh Parmesan! Summer veggies never tasted so good!
Prepare the sauce. Heat 2 tbsp olive oil in a 10-inch cast-iron or oven-safe deep skillet over medium heat. Add the onion and sauté until soft, 3-4 minutes. Add the garlic, 1 tsp salt, and the black pepper. Sauté until the garlic is fragrant, 1 minute. Stir in 1 tsp Italian seasoning and the crushed tomatoes. Bring to a simmer. Cook and simmer over medium-low heat until the mixture is slightly thickened, 10-15 minutes. Remove from the heat.

Prepare the vegetables. Add the sliced eggplant, zucchini, and tomatoes on top of the tomato sauce, alternating each type in no particular order in a circular pattern, standing upright. Cover all of the tomatoes with the vegetables. Sprinkle with the remaining 1 tsp Italian seasoning. Drizzle with the remaining 2 tbsp olive oil and ½ tsp salt.

Notes
Wait to add the garlic until the onion has had time to cook. The garlic just needs about 30 seconds to warm through and become fragrant. Otherwise, it can turn bitter.Utilize vegetables that are similar in diameter. They're going to get layered against each other, so it helps to try to get them to match in size.Cover the dish with foil. This allows the vegetables to fully bake and soften without burning. It creates a more consistent texture for the dish.
