As a French person, I had to share my authentic French ratatouille recipe.

I have seen so much confusion about this classic Southern France dish since the Ratatouille movie came out a few years ago.

In the Disney movie, Remy the Rat is a chef who cooks the ratatouille in a very fancy way where vegetables are layered in a baking dish and baked for hours.

However, a classic French ratatouille recipe is far from that Ratatouille movie recipe. What you see in the movie is in fact one of the ways fancy French restaurants serve ratatouille.

But let’s come back to the basics and share my easy ratatouille recipe, the one every French mum makes for their kids.

What Is Ratatouille?

Ratatouille is a French vegetable stew from the French Provence region.

It was originally, like many other humble recipes, a poor man’s food and was a way of using whatever vegetables were left.

An authentic French ratatouille, also called Ratatouille Niçoise is a vegetarian dish made of slowly cooked onion, red bell pepper, eggplant, zucchini, and tomatoes.

The particularity of a French ratatouille is all the flavors of olive oil and Mediterranean herbs like thyme, oregano, or rosemary.

How To Make Ratatouille

To make an easy French ratatouille recipe, you need only a bunch of summer vegetables:


Ratatouille ingredients with labels on a kitchen table.
  • Onion – White or brown onion, both work great. They need to be finely sliced.
  • Garlic Cloves – Crushed is preferable, but some people leave entire cloves in the dish.
  • Extra-Virgin Olive Oil – Olive Oil is an ingredient that can have a massive environmental footprint, so I like to source mine locally.
  • Red Bell Pepper – The authentic French ratatouille doesn’t use yellow bell peppers, but if you don’t have red bell pepper, the yellow variety would work.
  • Zucchini – The classic French recipe doesn’t use any yellow squash, only the green ones. They are typically not peeled.
  • Eggplant – I like to use darker eggplant, but purple, white or dark eggplant all have the exact same taste and texture.
  • Tomatoes – Roma tomatoes are my favorite pick for this recipe. Any in-season tomato would work though. Avoid cherry tomatoes if possible.
  • Canned Diced Tomatoes – This ingredient gives a lot of texture to the sauce.
  • Salt and Pepper
  • Thyme, Rosemary or Marjoram – fresh or dry.
The four steps of preparing a delicious Ratatouille..
  1. Preparing The Vegetables

First, wash the red bell pepper, zucchinis, eggplant, and tomatoes under cold tap water.

Peel the onion and chop it finely. Set it aside.

Then, deseed the red bell pepper and cut them into long strips. Next, cut the strips into small cubes. Set aside in a bowl.

  1. Slicing The Zucchinis

Trim the ends of the zucchinis, and cut them into thick slices.

The zucchinis cook faster so they must be cut into thicker slices. I like to cut the slice in half to create half moons, but you can recut the halves to form quarters if you prefer.

  1. Cubing The Eggplant

Trim the eggplant end, keep its skin on, and slice the vegetable into thick layers.

Place each layer on the chopping board and cut them into strips. Then, cut the strips into cubes of small size. Set aside.

  1. Cooking The Vegetables

The success of a great ratatouille is to cook the vegetable in the right order, or you will end up with some mushy vegetables at the end.

First, warm the olive oil in a large pot or non-stick cast iron pot or Dutch oven over medium-high heat.

Cook the onions until fragrant then add the garlic and stir in the red bell pepper cubes.

Keep cooking the red bell pepper, occasionally stirring, then cover the pan and let the vegetables cook for 5 minutes.

  1. Adding Zucchini

Remove the lid and add the zucchinis. Stir fry for 1 minute then add in the eggplant cubes and stir to combine.

Cover, reduce the heat, and cook for 2 to 3 minutes.

Uncover and now add the chopped tomatoes, diced canned tomatoes, herbs, salt, and pepper.

Give it a good stir, close the lid again, and bring to a light simmer.

  1. Simmer

Keep cooking the ratatouille over medium heat for 15 to 20 minutes. The cooking time varies depending on the size you cut the vegetables.

When the ratatouille is cooked, serve immediately.

Season with salt and pepper and serve as a light vegetarian meal or light side dish, following the serving suggestions below.

Tips For The Best Ratatouille Recipe Every Time

Classic French ratatouille is an easy vegetable stew, and the key to making it perfect every time is to follow these three tips:

  • Don’t Peel The Vegetable – Even the thick eggplant skin must stay in or the eggplant gets mushy.
  • Cut The Vegetable into small cubes of the same size, except for the zucchini – zucchinis cook faster, and as a result, if you want to keep some texture from zucchinis they must be cut in larger chunks. I like to cut them in half moons, but you can slice zucchinis in thick slices or large quarters.
  • Don’t Skip The Herbs  – what makes ratatouille so flavorsome is that combination of Provence herbs from the South of France. Of course, you can play with them, adding more of one or the other but focus on the classic ones which are thyme, rosemary, and marjoram. You can add fresh basil, but it’s less conventional.

What To Serve With Ratatouille

In France, ratatouille is a popular side dish to:

But some people also like to stir in some of the below ingredients in the ratatouille to turn it into a complete meal

  • Cooked Rice – can be white rice, brown rice, or cauliflower rice.
  • Cooked Pasta
  • Chickpeas
  • Cooked quinoa

Finally, a great addition to ratatouille is cheese, some of the below cheese are delicious to add on top of your dish.

  • Freshly Grated Parmesan
  • Crumbled Greek Feta Cheese
  • Grated Emmental

Storage Instructions

Ratatouille can easily be stored in an airtight container in the fridge for about 4 days.

In fact, it’s one of these dishes that have leftovers even tastier the next day. The flavors of the herbs and olive oil combine with the vegetables and are perfect reheated.

You can also freeze the leftover ratatouille in a sealed container or bags and leave them in the freezer for up to three months. Thaw them in the refrigerator the day before.


You can rewarm ratatouille in a microwave-safe dish for a few minutes or until warm.

Or, bring it back to a non-stick saucepan over medium heat.
