Ingredients
For the vegetables
- 1 medium eggplant (about 1 lb), cut into 3/4-inch cubes
- 2 medium zucchini, sliced into half-moons 1/2-inch thick
- 2 red bell peppers, cored and chopped into 1-inch pieces
- 1 large yellow onion, finely diced
- 4 cloves garlic, minced
- 4 ripe Roma tomatoes (about 1 1/2 lb), peeled and chopped, or 1 (14 oz) can crushed tomatoes
- 3 tbsp extra-virgin olive oil, plus more for finishing
- 1 1/2 tsp fine sea salt, plus more for salting eggplant
- 1/2 tsp freshly ground black pepper
For the herbs and finishing
- 1 tbsp herbes de Provence
- 2 tsp fresh thyme leaves
- 1 bay leaf
- 1/4 cup fresh basil leaves, torn
- 1 tbsp red wine vinegar
Directions
- Set the cubed eggplant in a colander, toss with 1 teaspoon of salt, and let it drain for 15 minutes; pat dry thoroughly with a clean kitchen towel.
- Warm the olive oil in a large heavy pot or Dutch oven over medium heat. Add the onion and cook until translucent, about 6 minutes, then stir in the garlic and cook 1 minute more until fragrant.
- Add the eggplant and cook, stirring occasionally, for 8 to 10 minutes until lightly browned and beginning to soften.
- Stir in the bell peppers and zucchini, season with salt and pepper, and cook for 6 to 8 minutes until the vegetables start to release their juices.
- Add the chopped tomatoes, herbes de Provence, thyme, and bay leaf. Bring to a gentle simmer, then reduce the heat to low and cook uncovered for 20 to 25 minutes, stirring now and then, until the vegetables are silky and the sauce has thickened.
- Stir in the red wine vinegar and taste for seasoning; adjust salt and pepper as needed.
- Remove the bay leaf, scatter the torn basil over the top, and finish with a drizzle of good olive oil before serving warm or at room temperature.
Cook’s Notes
- Salting the eggplant ahead of time removes bitterness and prevents it from soaking up too much oil.
- For the best flavor, use fully ripe summer tomatoes; out of season, good-quality canned San Marzano tomatoes work beautifully.
- Ratatouille tastes even better the next day once the flavors have melded; refrigerate and reheat gently or serve at room temperature.
- Serve as a main with crusty bread and goat cheese, alongside grilled fish or roast chicken, or tossed with pasta.
- Avoid covering the pot while simmering or the vegetables will steam and turn mushy instead of developing rich, caramelized edges.
