History of This French Classic Recipe

The word ratatouille comes from the French ratouiller and tatouiller, expressive forms of the verb touiller, which means “to stir up”.

The origin of the dish is in the area around Provence and Nice and compared to many other classics, it is a relatively new one.

It appeared for the first time in France back in the 18th century. Its name first appeared in English in 1877. 

This traditional French dish is close to the bohémienne , also Provencal recipe, both of peasant origin.

The Sicilian caponata is also close to the ratatouille, but slightly more on the tart side, by the addition of capers and vinegar.

Ingredients for Ratatouille

Although this version is not the most traditional around, I’m sticking to the classic recipe when it comes to the ingredients.

Traditionally, this hearty vegetable stew calls for simple vegetables such as:

  • courgette
  • aubergine
  • tomatoes
  • onion
  • garlic

Try to get the absolute best quality vegetables you can. It will definitely make this dish from good to AMAZING.

When you go shopping for the vegetables, look for courgette and aubergine that have a similar diameter, so that when you will slice them, they will stack together evenly.Easy Ratatouille in a large green cast iron shallow pan, bunch of thyme sprigs on the left side and a green napkin on the top right side.

Great fresh vegetables have a fantastic flavour on their own, but also make sure to choose super high-quality tinned tomatoes for the sauce.

I pick the Italian San Marzano variety whenever I find it, but any great organic plum tomato variety will do.

For the herbs, if you have Herbs de Provence at hand, totally go for it!

Otherwise, you’ll be just as happy with some freshly dried oregano (I used my mom’s Sicilian oregano!) and fresh thyme sprigs.

How To Make Ratatouille

Start by slicing all the veggies evenly, and set them aside.

Prepare the sauce:

Heat some olive oil in a pan, add in garlic and onion, followed by the tomatoes and bell peppers, sugar, balsamic vinegar, thyme and oregano. Cook for about 15 minutes, stirring occasionally, then season with sea salt and black pepper to taste.

Now, transfer the sauce into a blender or food processor, and blend until smooth (or leave it a bit chunky if you like the texture).

Pour the sauce over the bottom of a large shallow cast-iron pan, or baking pan.

Top with the veggies and bake:

Arrange one slice of each vegetable on the pan and continue until the pan is full.

To make things easier, stack the veggie slices in your hand then layer them into the pan. Season with salt and pepper, oregano and a nice swirl of olive oil.

It takes a few more minutes but will make this dish look like you spent the whole day on it!

Okay, now that you have layered up all the veggies, it’s time to transfer the pot in the oven. Bake for about 30 minutes.

Check after 20 minutes if the veggies are cooked through and the sauce is nicely bubbling on the sides.

Remove the pot from the oven, allow to cool slightly and serve.

Cook Ratatouille In A Cast-iron Pan 

For this recipe, I’ve partnered up with the well-known french brand Le Creuset.

I’ve been using their rosemary shallow casserole pot for making anything from classic tomato sauce, chicken stew and this delicious French vegetable stew, of course. 

It’s super handy to use a cast iron pan when prepping up this dish. You use it to prepare the sauce, then fold in the veggies and transfer the pot in the oven to finish off cooking.

Minimum efforts, and not much washing up to do afterwards!

What To Serve Ratatouille With

This side dish pairs well with many different dishes, but can also easily be served on its own, with some grilled bread.

It is one of those easy one-pan weeknight dinners. It’s super healthy, quick and fulfilling, and all you need to make it a meal is to serve it with your favourite protein.
