Homemade ratatouille with thin slices of eggplant, zucchini, yellow squash, onion, Roma tomatoes drizzled with olive oil and served over seasoned tomato sauce.


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 it 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 the 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!

What’s homemade ratatouille made of?

  • Eggplant
  • Zucchini
  • Yellow Squash
  • Onion
  • Tomatoes
  • Olive Oil
  • Tomato Sauce
  • Italian Seasoning
  • Sweet Basil
  • Salt
  • Black Pepper
  • Grated Parmesan for Topping

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 bake time.


How long does it last?

Until you eat it all! Just kidding.

Ratatouille lasts up to 4-5 days in the refrigerator.

Looks delicious! What size can of tomato sauce do you use?


Wednesday 10th of June 2020

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!
