Measurement guide
tbsp = tablespoon · tsp = teaspoon. Use measuring spoons, not table cutlery. Metric equivalents are estimates. ¾ = three quarters; ½ = one half; ¼ = one quarter.
Directions
Prepare the vegetables
Begin by thoroughly washing all produce. Cut the eggplant, zucchini, and both the red and yellow bell peppers into uniform 1-inch cubes—this ensures even cooking and a pleasing presentation. Finely chop the onion and mince the garlic cloves, as these will build the flavor base. Organize all prepared vegetables before beginning to cook.
Sauté onions and garlic
Heat two tablespoons of olive oil in a large heavy-bottomed skillet or Dutch oven over medium heat. Add the finely chopped onions and cook gently, stirring frequently, until they become translucent and soft, about five minutes. Then, add the minced garlic; sauté for an additional minute until fragrant but not browned, to avoid bitterness.
Cook the vegetables
Next, add the cubed eggplant, zucchini, and bell peppers to the skillet. Stir thoroughly to coat the vegetables with the oil and onion mixture, encouraging even browning and flavor development. Cook uncovered for approximately ten minutes, stirring occasionally to prevent sticking. Vegetables should begin to soften yet retain some firmness, avoiding a mushy texture.
Add tomatoes and herbs
Pour the crushed canned tomatoes into the pan along with the herbs de Provence, salt, and ground black pepper. Stir thoroughly to blend all ingredients evenly. Lower the heat to a gentle simmer and cover the skillet to encourage all flavors to meld together while preventing excess evaporation.
Simmer until tender
Allow the mixture to simmer uncovered over low heat for about thirty minutes. Stir occasionally to prevent any vegetables or sauce from sticking to the pan bottom. By this stage, the vegetables should be tender but not falling apart, and the sauce thickened to a rich consistency with the flavors fully married.
Finish with fresh basil
Finally, remove the skillet from heat and stir in the remaining tablespoon of olive oil and the freshly chopped basil leaves. This fresh herb addition adds brightness and a subtle aromatic layer to the dish. Taste the ratatouille and adjust salt and pepper as needed. Serve warm as either a main vegetarian entrée or a flavorful side dish to complement proteins.

Cooking tips
- For even cooking, cut all vegetables to a similar size.
- If the eggplant absorbs too much oil and seems dry, add a splash of water during cooking to prevent sticking.
- Use fresh herbs de Provence or dried if unavailable for authentic flavor.
- Let the ratatouille rest for a few minutes before serving to allow flavors to meld further.
Substitutions
- Swap bell peppers for diced yellow summer squash for a milder flavor and softer texture.
- Use fresh tomatoes peeled and chopped instead of canned crushed tomatoes; cook slightly longer to break down fresh tomatoes.
- Replace herbs de Provence with a mix of dried thyme, rosemary, oregano, and marjoram if needed.
Storage and reheating
Leftover ratatouille can be stored safely in the refrigerator in an airtight container for up to four days. When reheating, warm it gently over low heat on the stovetop or use short intervals in the microwave, stirring occasionally to ensure even heating. To preserve the best texture and flavor, avoid reheating the dish multiple times.
