Ratatouille is not complicated to make, but it is easy to get wrong: dump all the vegetables in together at once and the result is a watery mash where everything tastes the same. The Provençal technique cooks each vegetable separately in olive oil — eggplant, then zucchini, then peppers, then tomatoes — before combining them and letting the flavors marry slowly. The dish comes from Nice and the surrounding countryside, a summer preparation built around vegetables that ripen together in the August heat. It is at its best served the next day at room temperature, when the olive oil has risen and the flavors have deepened into something more unified than the sum of its parts. In Nice, a similar dish called 'tian' is arranged in overlapping slices and baked — the film version that became famous in animation.
Heat 2 tablespoons of olive oil in a large skillet over medium heat.
Add the diced eggplant and cook until it starts to soften, about 5 minutes. Remove from the skillet and set aside.
In the same skillet, add another 2 tablespoons of olive oil and the chopped onion and minced garlic. Cook until the onion is translucent.
Add the diced zucchini, yellow squash, red bell pepper, and yellow bell pepper to the skillet. Cook until the vegetables start to soften, about 5-7 minutes.
Add the chopped tomatoes, cooked eggplant, dried thyme, dried oregano, bay leaf, salt, and pepper. Stir to combine.
Reduce the heat to low, cover the skillet, and let the ratatouille simmer for about 30-40 minutes, stirring occasionally, until all the vegetables are tender and the flavors have melded together.
Remove the bay leaf from the skillet.
Adjust the seasoning with salt and pepper to taste.
Serve the ratatouille hot, garnished with fresh chopped basil.
Provençal vegetable stew: eggplant, zucchini, red and yellow bell pepper, tomato, onion, and garlic simmered in olive oil. The dish improves overnight and tastes better cold than hot.

Eggplant, zucchini, red and yellow bell pepper, tomato, onion, garlic, olive oil, thyme, and bay leaf.
Cook each vegetable separately before combining — eggplant first, then zucchini, peppers, then tomatoes. This prevents a watery texture and allows flavors to blend better without everything turning to mush.
Grilled fish, roasted chicken, crusty bread, or as a room-temperature side the next day. It tastes better cold than hot and improves as it sits.
