How to Make Ratatouille
Ratatouille is a Provençal vegetable stew that transforms humble summer vegetables into something extraordinary. Cut eggplant, zucchini, bell peppers, tomatoes, and onions into similar-sized pieces, then layer them in a baking dish with herbs and olive oil. Bake covered at 375°F for about an hour until the vegetables are tender and the flavors have melded together.

Ingredients
- 1 large eggplant
- 2 zucchini
- 2 bell peppers
- 4 tomatoes
- 1 large onion
- 3 tablespoons olive oil
- to taste salt
- to taste pepper
- fresh thyme
- 1 bay leaf
- splash white wine
- fresh basil
Step by step
- Prepare the vegetables. Cut 1 large eggplant, 2 zucchini, 2 bell peppers, 4 tomatoes, and 1 large onion into roughly equal pieces—about 1-inch chunks work best. Salt the eggplant pieces and let them sit in a colander for 30 minutes to draw out bitterness, then pat dry.
- Create the base. Heat 3 tablespoons olive oil in a large, oven-safe dish or Dutch oven. Sauté the onions until translucent, about 5 minutes. Add minced garlic and cook for another minute until fragrant.
- Layer the vegetables. Add the eggplant first since it takes longest to cook. After 5 minutes, add bell peppers, then zucchini after another 3 minutes. Finally, add tomatoes and stir gently to combine.
- Season and herb. Add salt, pepper, fresh thyme, and a bay leaf. Drizzle with more olive oil. Some cooks add a splash of white wine here—optional but nice.
- Bake covered. Cover with a lid or foil and bake at 375°F for 45 minutes. Remove the cover and continue baking for 15-20 minutes until vegetables are completely tender and slightly caramelized on top.
- Finish and rest. Stir in fresh basil and let the ratatouille rest for 10 minutes before serving. It tastes even better the next day.
Tips & troubleshooting
- Cut vegetables the same size so they cook evenly—uneven pieces mean some will be mushy while others stay raw
- Don't skip salting the eggplant—it removes bitterness and prevents the pieces from turning to mush
- Use the best olive oil you have for finishing—it makes a real difference in the final flavor
- Make it a day ahead if you can—ratatouille improves as the flavors meld overnight in the refrigerator
Variations
- Confit Byaldi. The elegant spiral version from the Pixar movie. Slice vegetables paper-thin and arrange in overlapping rows over a tomato base. Takes more time but creates a stunning presentation.
- Stovetop Ratatouille. Cook everything in a large skillet over medium-low heat, covered, stirring occasionally. Takes about 45 minutes total and gives you more control over texture.
- Grilled Ratatouille. Grill the vegetables separately first, then combine with herbs and a splash of balsamic. Adds smoky depth to the traditional flavors.
Questions
- Can I make ratatouille ahead of time?
- Yes, ratatouille actually improves with time. Make it up to three days ahead and reheat gently. The flavors develop and deepen as it sits.
- What do I serve with ratatouille?
- Serve it as a side dish with roasted chicken or fish, over rice or polenta, with crusty bread, or as a filling for omelets. It works as both a main dish and a side.
- My ratatouille turned out watery. What went wrong?
- Tomatoes and zucchini release a lot of water. Next time, remove the seeds from tomatoes and salt the zucchini along with the eggplant. Also, bake uncovered for the last portion of cooking time to evaporate excess liquid.
- Can I freeze ratatouille?
- You can freeze it for up to 3 months, but the texture will be softer when thawed. It works fine for using in other dishes like pasta sauce or as a base for soups.
