Ratatouille is a vegetable stew from Provence, built from whatever was ripening in the garden at the height of summer: aubergine, courgette, peppers, tomatoes, onion and garlic, all cooked down with olive oil and herbs until soft and deeply flavoured. At its simplest, ratatouille is a French vegetable stew made from aubergine, courgette, peppers, tomatoes, onion and garlic, slow-cooked together with olive oil and herbes de Provence until soft and richly flavoured.
The name itself points to the method. The name comes from the Occitan word ‘ratatolha’, roughly meaning ‘to stir up’ or ‘toss together’, a fitting description for a dish that’s traditionally more about technique than a fixed list of ingredients. The dish as most cooks know it today is younger than you might expect. Historical evidence suggests that no fully developed recipe identifiable as modern ratatouille appears in printed cookbooks before the late 19th or early 20th century, and earlier preparations varied considerably and did not consistently include the now-standard combination of aubergines, tomatoes, courgettes and peppers; the consolidation of these ingredients into a recognized dish appears to be a relatively recent culinary development, where a modern version does not appear in print until 1930. By the early 20th century, ratatouille became increasingly associated with the cuisine of Nice.
Texture is what separates a good ratatouille from a watery vegetable mush. Traditional Niçoise ratatouille cooks each vegetable separately before combining them, so every ingredient keeps its own texture and flavour rather than dissolving into a single sauce, a detail that separates an authentic Provençal ratatouille from quicker, one-pot versions. It is worth noting that the tightly layered, spiral version made famous by the animated film is a different, more modern dish called confit byaldi, created for fine dining rather than the home pot. This recipe is the rustic, chunkier stew that French households actually cook. It’s eaten warm as a side with roast meat or fish, at room temperature on its own with bread, or topped with a fried egg for a simple supper. It’s also earned its place as one of the classic Bastille Day dishes.
What you need
Aubergine (eggplant) is the vegetable that sets the texture: it turns silky and almost creamy once it’s browned and then stewed, and it soaks up the olive oil and tomato juices more than anything else in the pot. Courgette (zucchini) should stay slightly firm so the finished dish has some bite rather than turning to mush. Tomatoes carry the dish’s acidity and sweetness; ripe, in-season tomatoes or good tinned ones both work, and the two are listed as a swap below.
Herbes de Provence, the dried blend of thyme, rosemary, savory and often lavender, is the easiest way to get that South of France aroma without hunting down a bunch of fresh herbs. If you can’t find it, a mix of dried thyme, oregano and a pinch of rosemary gets you close.
| Ingredient | Swap | What changes |
|---|---|---|
| Fresh tomatoes | Tinned chopped tomatoes, same weight | Slightly more acidic and softer in texture, but reliable year-round |
| Aubergine (eggplant) | More courgette or sliced mushrooms, same weight | Lighter, less silky result; mushrooms add a savoury note instead |
| Herbes de Provence | 1 tsp dried thyme + 1 tsp dried oregano + pinch dried rosemary | Close in aroma, without the lavender note |

Ingredients
Vegetables
- 600 g Aubergine (eggplant), cut into 2cm cubes
- 400 g Courgette (zucchini), cut into 2cm cubes
- 1 Red bell pepper, deseeded, diced
- 1 Green bell pepper, deseeded, diced
- 200 g Onion, thinly sliced
- 4 cloves Garlic, minced
- 800 g Tomatoes, ripe and chopped, or tinned chopped tomatoes
To finish
- 90 ml Olive oil, divided, for frying
- 1 tbsp Herbes de Provence
- 2 Bay leaves
- 15 g Fresh basil, torn, to finish
- 1 tsp Salt and black pepper, to taste
Equipment
Large wide frying pan or skillet, Large heavy-based pot or casserole, Chopping board, Sharp knife
Method
- Salt the aubergine. Cut the aubergine into 2cm cubes, toss with a pinch of salt and leave in a colander for 20 minutes. Pat dry with a clean towel; this stops it from soaking up too much oil and helps it brown instead of steaming.
- Brown the aubergine. Heat 2 tbsp of the olive oil in a wide frying pan over medium-high heat until it shimmers. Fry the aubergine in batches for 5 to 7 minutes per batch, until golden at the edges. Set aside on a plate.
- Brown the courgette and peppers. Add a little more oil to the same pan and fry the courgette until lightly golden, about 5 minutes. Set aside, then fry the peppers for 4 to 5 minutes until starting to soften and colour at the edges. Set aside with the other vegetables.
- Soften the onion and garlic. Add the remaining oil to the pan, lower the heat to medium, and cook the onion for 6 to 8 minutes, stirring now and then, until it turns soft and pale gold. Add the garlic and cook for 1 minute until fragrant.
- Build the sauce. Add the tomatoes, herbes de Provence and bay leaves to the onion. Simmer uncovered for 10 to 15 minutes, stirring occasionally, until the sauce has thickened slightly and smells deeply of tomato and herbs.
- Combine and confit. Fold the browned aubergine, courgette and peppers back into the sauce. Cover, reduce the heat to low, and let everything simmer gently for 15 to 20 minutes, stirring only once or twice so the vegetables keep their shape.
- Finish and rest. Remove the bay leaves. Season with salt and pepper to taste, stir through the torn basil, and let the pot rest off the heat for 10 minutes before serving so the flavours settle.

Tips for success
Cut everything to a similar size. Aim for roughly 2cm cubes across the aubergine, courgette and peppers so they all finish cooking at about the same time.
Salt the aubergine before you start. A light salting and 20 minutes’ rest draws out excess moisture, so the cubes brown instead of steaming when they hit the hot oil. Pat them dry first.
Fry each vegetable in its own batch. Crowding the pan drops the oil’s temperature and the vegetables boil in their own liquid instead of browning. Work in batches and give each one room to colour.
Keep the final simmer gentle and short. Once everything is combined, a low, lid-on simmer lets the vegetables finish together without collapsing. Stir as little as possible.
Taste before you serve. Tomatoes vary in acidity, so adjust salt and a small pinch of sugar at the end if the sauce tastes sharp.
Storing and reheating
Let the ratatouille cool before covering and refrigerating; use within 3 to 4 days, in line with general guidance from the USDA on cooked vegetable dishes. It also freezes well in an airtight container for up to 3 months. Reheat gently on the stovetop or in the microwave until it is steaming hot all the way through, stirring partway if using a microwave so it heats evenly.
Serving ideas
Serve it warm alongside roast or grilled chicken, lamb or white fish, or spoon it over soft polenta or rice for a simple vegetarian main. A fried or poached egg on top turns leftovers into a quick weeknight dinner, and crusty bread is the natural accompaniment for mopping up the juices.
Diet and allergen notes
This recipe is vegetarian, vegan and dairy-free as written, and naturally gluten-free since it contains no flour or wheat-based thickeners. It is halal by nature, containing no meat or alcohol. It is not suitable for a strict keto diet, since tomatoes and onion bring enough natural sugars to push up the carb count. There are no common allergens in the ingredient list below; always check the label on any tinned tomatoes if you have a sensitivity to added ingredients.
Questions
Can I make ratatouille ahead of time?
Yes, and many cooks prefer it that way. The flavours settle and deepen overnight in the fridge, so making it a day ahead and reheating gently is a good option for entertaining.
Why is my ratatouille watery?
This usually happens when the vegetables are stewed together from raw rather than browned separately first, or when the aubergine wasn’t salted and dried before frying. Browning drives off surface moisture and builds flavour that a straight simmer can’t.
What’s the difference between ratatouille and confit byaldi?
Ratatouille is made of diced vegetables, simmered together in sauce, while confit byaldi uses thinly sliced vegetables layered without sauce on top of a tomato base. Confit byaldi is the elegant, layered dish popularised by the animated film; this recipe is the everyday rustic stew.
