Easy 4 ingredient rainbow ratatouille – vegan and gluten-free

We’ve all seen the heart-warming animated movie Ratatouille about an unusual wanna-be French chef. The dish ratatouille gained real world-wide popularity after that. 

To be honest, I’ve prepared a similar dish before I knew how it’s called or that it’s French. This is because vegetables-only dishes are very popular in my family growing up. So we had a version of this baked veggie dish regularly when I was little.

However, after seeing the movie I was obsessed with making a rainbow ratatouille. It’s beautiful and I was so impressed. So, naturally this summer I decided to give it a go.

The result is not the most beautiful, picture-perfect rainbow ratatouille. My strong side is not food presentation, unfortunately. But it’s very delicious and can be served on its own or as a side dish.

Let’s get baking!


  • 2 medium-sized zucchini – I used different colours for more ‘pop’
  • 1 big or 2 medium-sized eggplants
  • 2 yellow onions
  • 2 ripe red tomatoes


The most important step for your rainbow ratatouille is slicing the vegetables. This will determine how your dish is ordered and presented. So, I picked relatively similar in size veggies. 

I start by slicing the zucchini, onion and tomato in circles. Since the eggplant I used was bigger than the other veggies, I cut it in half before slicing in semi-circles.

Note – I chose not to peel the vegetables. This way I had a colourful plate to present to my guests.

Now the hardest part. Once I’ve cut all the veggies in the chosen shape, I have to start arranging them. The challenge here is to place everything in concentric circles evenly and without falling apart.

I haven’t done a great job with that since I was in a hurry. But with a little patience you can make a beautiful dish.

When happy with the result, season with salt and fresh oregano. Use 2-3 tablespoons of olive oil if you wish. Bake in pre-heated oven (240 C or 450 F) for around 45 minutes.

Serve hot or cold, with tomato sauce on the side as a main dish or on its own as a side dish. There are so many options! Which one did you choose?
