Provençal peasant dish from Nice, named from the Occitan ratatolha ('to stir up'). 18th-century farmer's stew that originally combined whatever summer vegetables ripened together. The separately-cooked-then-combined method was codified by Auguste Escoffier and refined further by Michel Guérard in the 1970s — the tian-style fanned arrangement seen in Pixar's Ratatouille (2007) is technically a confit byaldi, Thomas Keller's invention for the film.
A celebration of summer's bounty, this dish is a vibrant medley of vegetables that tastes like sunshine.
Eggplant, zucchini, bell pepper, onion, tomato — each cooked separately in olive oil, then combined with garlic, herbs, and a slow simmer. Vegetables hold their shape but yield easily under a fork; the oil at the bottom is stained tomato-red and herb-green. Served warm or room temperature, often the second day when flavors have settled. Bread on the side, never pasta.
Cooking each vegetable separately is non-negotiable. Eggplant needs more time and oil than zucchini; tomato needs reduction the others don't. Throw them all in one pot and the wet vegetables steam the dry ones, the eggplant turns to mush, and the dish goes brown-grey instead of staying distinct. Combine only at the end, then a short shared simmer to marry.
Variations
Confit byaldi (the sliced-fanned-out pretty version); ratatouille traditionnelle (rustic, mixed); soupe au pistou is the soup form; piperade Basque is similar but only pepper-and-tomato.
