This ratatouille recipe layers eggplant, zucchini, yellow squash, and tomatoes over a savory tomato base for a colorful, vegetable-forward meal. It can be served as a meatless main course or as a side dish, and late summer is a particularly good time to make it when many of the vegetables are in season. The preparation is simple: cook the tomato sauce, arrange the sliced vegetables, then bake until tender.

Ratatouille Recipe Ingredients
The vegetables provide most of the flavor and texture, so choose fresh produce when available. This recipe serves 4 and is naturally vegan, dairy-free, and gluten-free as written. Check the labels on packaged tomato sauce if you need to avoid specific ingredients.
- 1 tablespoon olive oil
- ½ yellow onion
- 4 cloves garlic
- 1 carrot
- Salt and black pepper
- 15 ounces tomato sauce
- 1 eggplant
- 1 green zucchini
- 1 yellow squash
- 2 tomatoes
- 1 tablespoon chopped parsley

How to Make Ratatouille
- Prepare the tomato base. Finely chop the onion and carrot, then mince the garlic. Warm the olive oil in a pan over medium heat. Add the onion and carrot and cook until softened and the onion starts to brown.
- Season and add the sauce. Stir in the garlic, salt, and pepper. Cook for about 1 minute, then add the tomato sauce and mix. Remove the pan from the heat.
- Slice the vegetables. Cut the eggplant, zucchini, yellow squash, and tomatoes into half-moon slices. Keep the eggplant, zucchini, and squash relatively thin and the pieces similar in size so they cook evenly. Tomato slices can be slightly thicker.
- Arrange in the baking dish. Spread the tomato mixture in an 8×8-inch square casserole pan. Layer the sliced vegetables over the sauce, arranging them so that at least half of each piece is submerged.
- Bake until tender. Cover the dish with aluminum foil and bake at 375°F for 45 minutes. Remove the foil for the final 10 minutes.
- Finish and serve. Sprinkle with chopped parsley and serve warm.
Practical tip: A sharp knife works well for slicing the vegetables. A mandoline can help create more uniform slices, but use its hand guard and handle the blade carefully.

Tips for a Flavorful Ratatouille
- Use fresh, in-season vegetables when possible; their flavor and texture are central to the dish.
- For extra flavor, add fresh basil, thyme, red pepper flakes, or Italian seasoning.
- Grated Parmesan can be added before serving, but the dish will no longer be vegan or dairy-free.
- To prepare ahead, assemble the dish, cover it with foil, and refrigerate it before baking. Bake when ready to serve.
- Serve with toasted garlic bread, or spoon the vegetables and sauce over pasta or rice. For a fully plant-based meal, choose bread without butter.
Leftovers can be refrigerated for at least 3 days. For a different way to use them, blend the vegetables and sauce to your preferred texture, then reheat on the stovetop or in the microwave as a soup.
