This is an Italian version of the French ratatouille, quicker and healthier to make than a traditional one, and you are not compromising on taste and creaminess. All vegetables are baked in the oven at once. Perfect dish for a vegan, vegetarian, or regular meal.

Jump to:
Traditionally, ratatouille is prepared by frying summer vegetables-such as peppers, eggplant, zucchini, onion, and tomatoes-individually with herbs and spices like basil, garlic, or Provençal herbs, which are typical of the South of France.
This method ensures that each vegetable retains its own distinct flavor and texture.
In contrast, this Italian-inspired version takes a simpler approach by baking all the vegetables together in the oven.
While it can be compared to ciambotta or giambotta, the classic Italian vegetable stew from the South of Italy, I grew up eating it during the summers.
Ciambotta often includes potatoes and cooks the vegetables in stages to prevent overcooking; this recipe is different.
Here, the vegetables are roasted together with tomato sauce, allowing them to caramelize and meld into a rich, creamy texture.
By cooking everything at once, the flavors combine beautifully, resulting in a melt-in-your-mouth vegetarian ragù.
The end result is a hearty, flavorful dish that's as versatile as it is delicious.
Serve it as a side dish, mix it with rice, pasta, or polenta, or enjoy it on its own with some crusty bread.
This baked ratatouille offers a unique twist on both the French classic and its Italian variations, delivering maximum flavor with minimal effort.

Ingredients
- Red peppers: For a vibrant color contrast, use red peppers, but yellow or green peppers work just as well.
- Zucchini: Opt for small zucchini, as they have fewer seeds and a sweeter flavor, perfect for this dish.
- Eggplants: Slim, small eggplants are best for avoiding bitterness and excessive seeds.
- Onion: Red onions are ideal for their sweetness, but regular yellow onions are a fine substitute.
- Fresh basil: Fresh basil brings out the best flavor, but if unavailable, substitute with Provençal herbs for a French-inspired twist.
- Salt: Enhances the vegetables' natural sweetness.
- Extra virgin olive oil: Use high-quality olive oil for the best depth of flavor.
- Black pepper: To taste, for a subtle kick.
- Chili (optional): Add if you prefer a hint of heat.
- Tomato sauce: A can of tomato sauce is key to creating the creamy, hearty texture, transforming the dish into a vegetarian ragù.

Step-by-step instructions with images
Prepare all the ingredients:
- Wash all the vegetables thoroughly, peel the eggplants, and cut all the vegetables (peppers, zucchini, eggplants, and onions) into evenly-sized cubes. This ensures they cook consistently.
- Grease a large baking tray generously with extra virgin olive oil to prevent sticking and to enhance the flavor of the vegetables.
Pro tip: I usually use a silicone oven sheet to line the baking tray instead of baking paper. It's washable, reusable, and makes cleaning the tray much easier. Plus, it reduces the need for extra seasoning since it prevents sticking.

- Arrange all the vegetables on the tray.
- Add the fresh basil leaves or Provençal herbs if substituting
- Season with salt and black pepper, then stir everything well to coat the vegetables evenly in oil and spices.
- Bake the vegetables in the oven at 180°C (350°F) for 30 minutes.
- After 30 minutes, remove the tray from the oven and give all the vegetables a good stir. This helps them caramelize evenly.
- Return the tray to the oven and bake for another 30 minutes.
- After the second baking period, add the tomato sauce. Stir well to combine, ensuring the sauce coats the vegetables evenly.
- Increase the temperature to 200C (390F) Place the tray back in the oven and bake for an additional 30 minutes.
- Once done, the ratatouille will be soft, creamy, and caramelized, with the vegetables beautifully melded together.
- Serve immediately while warm, or store it in the refrigerator to serve the next day. The flavors deepen and improve over time, making it an excellent make-ahead dish.

It's perfect for dinner parties since it can be made ahead of time and stored in the fridge for up to 4 days.

Notes
- Ingredients first, for the best ratatouille buy the best vegetables grown locally and in season
- Use a large baking pan so the vegetables will caramelize evenly
- Stir the vegetables every 30 minutes
- Use a good tomato sauce, I would recommend Mutti
- Make a large quantity and serve the next day, it will be even better as the flavours would have blended together

Excellent and Easy! I’ve made this recipe several times. Since I’m WFPB, I use broth instead of oil. I also sometimes add mushrooms and sometimes chickpeas. Add salad and maybe rice and it’s a complete meal. I like the creaminess. It’s my go to recipe for ratatouille. Thank you!
