This baked ratatouille features a jaw-dropping arrangement of veggies smothered in a garlicky tomato sauce. Eggplant, zucchini, squash, tomatoes… oh my!

For many of us (me included), I didn’t know what ratatouille was before the Disney movie “Ratatouille” came out. Only then did I start looking into this delicious veggie-filled dish and decide “wow, I have to make this!” The more research I did, the more I fell in love with this dish.
So now, I want to share the knowledge with you! Ratatouille is a French vegetable dish originating in the region of Provence, France. The veggies are traditionally flash-seared, and then slowly simmered for a perfectly tender texture and savory flavor. Fun fact — authentic ratatouille is actually a stew of veggies, not the artfully arranged spiral like we see in the movie (although you can totally do that too!).
Even if the movie tricked us, I love ratatouille because the fresh flavors marry together so well and the colorful mix of veggies is beautiful. It’s also super customizable! For example, on days when I don’t have enough zucchini, I can easily swap it for more eggplant or yellow squash.

How To Make Baked Ratatouille
Even though the name sounds fancy, ratatouille is a dish simple enough for busy moms like me to throw together. Slice up the veggies, make the sauce, then assemble everything in the pan!
- Sauté the veggies for the sauce: In a large oiled skillet over medium-high heat, sauté the chopped onion and bell pepper until soft. Add the garlic and sauté for another minute, then add the canned tomatoes, salt, and half of the Italian seasoning.
- Simmer and blend the sauce: Simmer the sauce for 10 minutes, then transfer it to a blender or food processor and blend until it’s smooth.
- Assemble the sliced veggies in the pan: Pour the sauce into an 11-inch skillet or pan, then arrange the sliced veggies in a spiral. Top the veggies with a drizzle of oil and the rest of the Italian seasoning.
- Bake the ratatouille: Cover the pan and bake in a 375°F oven for 30 minutes. Remove the lid, then bake for another 15-30 minutes.
Hot tip: For “meatless Mondays,” serve ratatouille with something carby like a baguette or basmati rice to keep your stomach full for a while.




Tips From the Kitchen
Do you or anyone in your family think veggies are “bleh?” Follow these tips for the best ratatouille, and prepare to have your mind blown.
- Pick similarly sized vegetables. Ideally, the zucchini, squash, and eggplant should be similar in diameter and length to guarantee even cooking. If the eggplant is much wider, cut it in half lengthwise before slicing.
- Salt and drain the tomatoes. This helps to draw excess liquid out of the tomatoes to prevent a watery stew. While you make the sauce, sprinkle salt over the sliced tomatoes and allow them to drain in a colander set over a bowl. Pat the tomatoes dry before assembling the dish.
- Use a mandoline slicer. Save time and ensure the veggies cook evenly by using a mandoline to slice them consistently. Adjust the setting to 1/8 inch, and watch your fingers!
- Consider presentation. This version of ratatouille is meant to be a celebration of summer vegetables. Make it eye-catching with a pretty baking dish like this one (anything 11-13 inches in diameter works). For a pop of green, sprinkle fresh parsley, fresh basil, or fresh thyme on top.

Storage & Reheating
Nothing compares to ratatouille fresh out of the oven, but I wouldn’t blame you for wanting to save leftovers! You can enjoy the veggies cold or warm — they’re delicious both ways.
- Storage: Store leftover ratatouille for up to five days in an airtight container in the refrigerator.
- Reheating: For the most consistent results, place the ratatouille in a covered pan and bake it in the oven at 300°F for 10-15 minutes. If you’re in a hurry, pop it in the microwave on the reheat setting.
Hot tip: Avoid freezing ratatouille, as the veggies are bound to turn out mushy.

What should I do if I don’t have a blender or food processor?
Hi Melissa, You could dice it up into tiny pieces after cooking them. Hope this helps. 🙂
Finally a way to hide eggplant for my family. This was amazing. It is work for the cook however it is worth every bite
Thank you so much! I’m thrilled it was a hit with your family. I totally get what you mean about the effort—it’s definitely one of those ‘labor of love’ recipes, but hearing it’s worth every bite makes it all worthwhile.
Wow, this was amazing! But sorry, the eggplant has to go. 🤢😅 But really, the sauce was so good
Now trying to store some.
Haha, no need to apologize—eggplant isn’t for everyone! 😊 I’m glad you loved the sauce, though—that’s what really ties it all together! If you're storing some, make sure to let it cool completely before refrigerating. Thanks for sharing your thoughts!
Is there any vegetable that could sub the eggplant??
You can simply omit it, or add more of your favorite other veggies already used in the dish.
Trying this tonight. It is currently in the oven. If this works out good I will use it on the Thanksgiving menu. Thank you very very much.
I hope it turns out amazing for you! Let me know if it earns a spot on your Thanksgiving menu.
