Homemade ratatouille with thin slices of eggplant, zucchini, yellow squash, onion, and Roma tomatoes drizzled with olive oil and served over seasoned tomato sauce. Great for using up leftover vegetables from the garden!
Ratatouille Origin
Ratatouille originates in France and is known as “peasant food” that farmers threw together when their summer crops came in.
This particular recipe serves as a main or side dish and is very versatile.
It’s great as-is with a side of crusty bread or can be served with noodles, roasted chicken breast or fish, or even with eggs for breakfast.
I once cooked some spaghetti noodles al dente and placed them in the tomato sauce, then topped it with vegetables. My family loved it!
This dish is great for using leftover vegetables too and the choices are not limited to only those listed in this recipe.
Potatoes, sweet potatoes, red and green peppers, beets, carrots, leeks, or mushrooms are all great additions!

The Perfect Slice
To get vegetables cut this fine it’s quickest and easiest to use a vegetable slicer. I love this slicer from Amazon.
It’s perfect for slicing and grating, everything stays confined to the container as you slice for easier cleanup, and your hand is protected while you slice with a vegetable holder.
Can you make ratatouille ahead?
Yes! It’s great to throw together in a dish (or deliberately place in a pretty pattern) a day ahead of time and cover in an airtight container in the refrigerator.
The next day, uncover and pop in the oven for the same baking time.
How long does it last?
Until you eat it all! Just kidding.
Ratatouille lasts up to 4-5 days in the refrigerator.

Homemade Ratatouille
Ingredients
- 1 Large Eggplant
- 1 Large Zucchini
- 1 Large Yellow Squash
- 1 Large Onion
- 3 Roma Tomatoes
- 1 tablespoon Olive Oil
- 14.5 ounce Can Tomato Sauce
- 2 tablespoon Italian Seasoning
- ½ teaspoon Sweet Basil
- 1 teaspoon Salt
- Black Pepper, to taste
- Freshly Grated Parmesan, for topping
Instructions
- Preheat oven to 350 degrees Fahrenheit. Rinse all vegetables prior to cutting each into thin slices, about ⅛"-¼" thick coins.
- Mix tomato sauce with Italian seasoning, sweet basil, and salt. In a baking dish with at least 2-3" sides pour the seasoned tomato sauce into the bottom and spread evenly.
- Begin layering vegetables flat over the top of the tomato sauce in a circular pattern, alternating each vegetable as you go. Once the tomato sauce is completely covered with the beautifully colored vegetables, drizzle olive oil on top and sprinkle with salt and black pepper to taste.
- Bake for 55-60 minutes until vegetables are tender and tomato sauce is bubbling. Sprinkle with grated parmesan before serving.

Could I use yellow zucchini instead of squash?
Yes, yellow zucchini can be used in place of yellow squash. It has a slightly sweeter flavor, but will be delicious in this blend of vegetables.

I’d love to make like the picture with veggies standing on their sides. Do I need extra sauce for that?
No extra sauce is needed for the vegetables to stand upright. The 14.5 ounce can gives you plenty of sauce. Let me know how it turns out!
Looks delicious! What size can of tomato sauce do you use?
I used one 14.5 ounce can and my dish was a 2 quart that’s 10″ round and the sauce came up about 1″- 1.5″. If you happen to use more vegetables or a bigger dish you might need more sauce than that to spread out.
I apologize for not having the amount listed in the recipe card. There was an update to all my recipe cards recently and it seems like it deleted some of the amounts I had. I’m trying to fix them all, so thank you for pointing that one out!
