This vegan ratatouille tian is a combination of two easy French dishes, and is perfect for flavorful vegetables like eggplant, tomatoes, and summer squash.
As summer heat hits at full blast– the vegetables in my garden are happily growing bigger and bigger.
The baskets of tomatoes, summer squash, and other veggies and herbs at the farmer’s market are also overflowing– and this all makes me super happy.
I happily spend my summers making slow-roasted tomatoes, stuffed squash blossoms, tomatoes provençal, and homemade hot sauce. And I make ratatouille!
One of my favorite ways to use the veggies is in this simple, delicious, and vegan Ratatouille Tian.
What is Ratatouille?
Ratatouille is a French vegetable dish that features eggplant, summer squash, and tomatoes. Traditionally, it’s served as a stew, but here we’re switching things up!
What is a Tian?
A tian is a layered French vegetable dish where veggies are carefully arranged in a casserole dish, and then roasted until tender.
For this vegan ratatouille tian, we’re using the classic ratatouille veggies, and arranging them gorgeously into a tian.
How Do I Make vegan ratatouille tian?
Start by adding tomato sauce and fresh herbs to a baking dish or large cast iron pan.
Next, slice up the vegetables, layer them in the pan, and roast it!
Really, it’s that easy.
Should I Use a Mandoline to Cut the Vegetables?
A mandoline is a vegetable slicing tool that will help you cut the vegetables evenly and more quickly. I own this OXO mandoline.
However, if you don’t have a mandoline, stick with a well-sharpened knife. This is my favorite knife for slicing veggies.
Can I Make vegan ratatouille Ahead of Time?
Up to one day ahead: Slice the veggies and arrange them in the dish. Cover the dish and refrigerate.
Wait and roast the veggies until about 45 minutes before serving.
I’m Missing one of the Veggies. Can I Substitute?
Yes! Swap any of the vegetables in this dish for more of one of the other veggies. This dish is also delicious with bell pepper and onion added.
Is it Hard to Layer the veggies for this vegan Ratatouille?
No, but it does take a little bit of time to arrange them gorgeously.
Arrange the veggies concentrically, alternating vegetables as you go. If you have extra veggies, you can add them into the layers.
No time to make the concentric layers? You can also arrange your veggies in rows.

So we have planted about 10 zucchini plants and cant wait for our bounty this summer. I will try this (altho not sure if I can pull of the presentation)
This tian looks beautiful and it is such a great way to use all the fresh summer veggies!! YUM!
It looks amazing! I always end up buying too many veggies at the farmers market and find myself stumped on what to do with them.
Thanks! Me too- And then this happens lol
This is probably one of the most beautiful dishes I’ve seen, if not the healthiest.
Awww thanks Dan!

It’s. So. Pretty! This is perfect for my garden right now, which is producing so much zucchini, squash, and tomatoes faster than I can blink it seems.
My garden is finishing up for the year sadly! But I’m still craving all the summer veggies!
