What the thing is
Ratatouille is a stew or sauté of seasonal summer vegetables cooked in olive oil.
It is sometimes called ratatouille niçoise. Methods and cooking times vary considerably by region and household, but it is typically made with tomatoes, onions, garlic, courgettes, aubergines and bell pepper, seasoned with Provençal herbs: fresh basil, marjoram or fennel, or dried thyme, bay leaves or herbes de Provence.
Its name comes from the Occitan ratatolha and the French verbs ratouiller and tatouiller, forms of touiller, “to stir” or “to toss”. In the early 19th century the word described a coarse stew or mixed dish, sometimes pejoratively, rather than a specific vegetable preparation, so the name predates the standard recipe.
Where it came from
It originated in the Provence region of southern France, particularly associated with Nice and its surrounding region, as a practical means of using surplus summer produce.
Vegetable stews had long been made in Provence, but historical evidence suggests that no fully developed recipe identifiable as modern ratatouille appears in printed cookbooks before the late 19th or early 20th century. A modern version does not appear in print until 1930. Earlier preparations varied and did not consistently include the now-standard aubergines, tomatoes, courgettes and peppers.
By the early 20th century it was increasingly associated with the cuisine of Nice, and its inclusion in major culinary reference works helped codify it as a distinct Provençal specialty. In the mid-20th century, cookbooks for English-speaking readers presented it as emblematic of southern French cooking, which carried it from regional peasant dish to a recognised part of French cuisine.
What it gets right
It honours seasonal abundance. It uses olive oil as both medium and marker of place. It names itself after the act of stirring—a gesture of labour, not artistry.
Regional cookery texts describe vegetables cooked either together or sautéed separately before being combined. The Larousse Gastronomique says that, according to the purists, the different vegetables should be cooked separately, then combined and cooked slowly together until they attain a smooth, creamy consistency. Felicity Cloake wrote in the Guardian in 2016 that, given the dish’s relatively recent origins, there is a great variety of methods of preparing it.
What it gets wrong
It is often presented as ancient Provençal tradition, but its core ingredients—tomatoes, peppers, squash—did not enter French diets until centuries after the region’s medieval culinary forms were set. Tomatoes, peppers and squash reached France after the 16th century, following contact with the Americas, but were not widely accepted as food until the 18th and 19th centuries. Aubergine arrived earlier, through Mediterranean culinary influence, and was established in southern France before spreading north.
Why it matters now
It reveals how national dishes are retrofitted: ingredients once distrusted (tomatoes, peppers) become essential, and a term once pejorative (‘coarse stew’) becomes a signifier of authenticity.
From the late 20th century, professional chefs began reinterpreting it with refined techniques. One variation, Confit byaldi, created by Michel Guérard, arranges the vegetables in thin, carefully layered slices rather than a stew. Confit byaldi and similar interpretations differ substantially from the rustic preparation of Provençal home cooking. Similar vegetable dishes exist in many cuisines, among them piperade, tian, pisto, caponata, lecsó and zaalouk. In 2007 the Pixar film Ratatouille gave the dish widespread exposure around the world.
Is it worth your time
Yes—if you care about how ordinary food becomes emblematic, and why a dish made from surplus vegetables now stands for culinary legitimacy.
