Ratatouille Recipe (Roasted & Classic)
This authentic French ratatouille combines roasted eggplant, zucchini, tomatoes, and peppers with Olivea EVOO and fresh herbs. A Provence classic that tastes better the next day.
Recipe Success Tips
Slice vegetables to even thickness for consistent cooking.
Use a mandoline set to 1/4-inch thickness. Uniform slices cook at the same rate and look elegant when served. Thinner pieces will collapse into the sauce; too thick and the centers stay firm while edges char.
Pat eggplant dry after cutting to minimize splattering.
Eggplant releases water as it roasts. Pat it dry on paper towels, then toss with Olivea EVOO. This helps it brown rather than steam, and gives you better control over the oil ratio.
Roast vegetables in separate batches or on larger pans so nothing overlaps.
Crowded pans trap steam and create soggy ratatouille. Give vegetables room to breathe. If your pan is small, use two sheet pans or cook in batches. You want caramelized edges, not soft centers.
Finish with a generous drizzle of extra virgin Olivea EVOO and fresh basil.
This is where the magic happens. The fresh, grassy notes of high-quality EVOO cut through the richness and add a brighter flavor. Never cook your best olive oil; save it for the finish.
Taste and season at the very end, after the sauce has reduced.
As the tomatoes break down, their acid mellows and their natural sweetness concentrates. Wait until the last minute to add salt and pepper so you don't over-season.
Serve at room temperature or chilled for even better flavor integration.
Ratatouille improves with time. Make it a day ahead, refrigerate covered, and let it come to room temperature before serving. The flavors meld and deepen as it sits.

How to Cook Ratatouille Recipe (Roasted & Classic)
PREP
1
Slice eggplant, zucchini, and bell peppers to 1/4-inch thickness. Pat eggplant slices dry with paper towels and set aside on a clean surface; this prevents water from escaping during roasting and allows the vegetables to caramelize rather than steam.
2
Preheat oven to 425 degrees F. Divide the eggplant slices between two large roasting pans (do not crowd them). Drizzle with 3 tablespoons of Olivea EVOO per pan, season with salt and pepper, and roast for 12 minutes until the edges are golden and the eggplant is soft but not collapsed.
3
Remove eggplant from oven. In the same pans (or a new one if the bottoms look too charred), add zucchini slices, drizzle with another 3 tablespoons of Olivea EVOO per pan, season with salt and pepper, and roast for 10 minutes until tender. Transfer roasted eggplant and zucchini to a bowl and set aside.
ROAST PEPPERS
4
In the same pans, arrange bell pepper strips in a single layer, drizzle with the remaining 2 tablespoons of Olivea EVOO, season with salt and pepper, and roast for 8 minutes until the edges are softened and lightly charred. Transfer to the bowl with the eggplant and zucchini.
5
While the peppers roast, prepare the sauce base. In a large heavy-bottomed pot, sauté the diced onion over medium heat until softened and translucent, about 4 minutes (you can add a small splash of Olivea EVOO if the pot is dry). Add minced garlic and cook until fragrant, about 30 seconds. Do not let the garlic brown.
SIMMER
6
Add the crushed tomatoes to the pot with the onion and garlic. Stir in the fresh thyme and bay leaf. Simmer over medium-low heat, uncovered, for 10 minutes to allow the tomato flavors to concentrate slightly.
7
Add all the roasted vegetables (eggplant, zucchini, and peppers) to the pot with the tomato sauce. Gently fold to combine without breaking apart the vegetables. Simmer for another 8 to 10 minutes, stirring occasionally. The sauce should be slightly thickened and the vegetables should be tender but still hold their shape.
8
Remove the bay leaf. Taste and adjust seasoning with salt and pepper. The ratatouille should taste bright and balanced: savory from the tomatoes and garlic, herbaceous from the fresh basil and thyme, and rich from the EVOO.
FINISH
9
Transfer ratatouille to a serving bowl or platter. Just before serving, drizzle with a final 2 to 3 tablespoons of Olivea EVOO and scatter fresh basil over the top. This finishing drizzle adds brightness and depth that cannot come from cooking oil.
10
Serve warm, at room temperature, or chilled. Ratatouille tastes even better the next day after the flavors have melded overnight. Store in an airtight container in the refrigerator for up to 5 days.
Recipe Notes
Serve ratatouille as a vegetable side dish alongside grilled fish or roasted chicken. It's also delicious as a light lunch on its own, with crusty bread and a salad. At room temperature with fresh goat cheese and a drizzle of EVOO, it becomes an elegant appetizer. Pair with a dry white wine like Provence rose or Sauvignon Blanc.
For a no-cook version, blanch the vegetables separately, chill, and serve with a bright vinaigrette made from red wine vinegar and Olivea EVOO. You can also layer the ingredients in a gratin dish and bake covered, creating a more cohesive, stewlike dish. Some cooks add a spoon of tomato paste for deeper flavor, or a pinch of saffron for warmth.
Ratatouille is ideal for make-ahead cooking. Prepare it up to two days in advance and store covered in the refrigerator. The flavors actually deepen and improve as it sits. Reheat gently over low heat on the stovetop, or serve chilled directly from the fridge. It freezes well for up to three months in an airtight container; thaw overnight in the refrigerator before reheating.
Ratatouille's flavors are best appreciated when the dish cools to room temperature. Cold temperatures mute flavors; warm temperatures can make it taste a bit dull. Room temperature allows the acid from the tomatoes, the sweetness of the vegetables, and the richness of the Olivea EVOO to balance perfectly on your palate.

Frequently Asked Questions
Ratatouille is a classic French vegetable stew from Provence made with eggplant, zucchini, tomatoes, bell peppers, and aromatics like garlic and herbs.
