Provençal Ratatouille with Green Olives & Basil

Directions

1. Salt and dry the eggplant

   Toss the eggplant with 1/2 teaspoon salt in a colander and let it stand for 15 minutes while you cut the remaining vegetables. Spread it on a clean towel and blot very dry. This brief treatment seasons the centers and removes surface moisture that would otherwise impede browning.

2. Brown the eggplant

   Heat 2 tablespoons oil in a wide 6-quart Dutch oven over medium-high. Add half the eggplant in one layer and cook for 5 to 6 minutes, turning twice, until browned but not fully soft. Transfer to a bowl and repeat with 1 tablespoon oil and the remaining eggplant.

3. Color the zucchini

   Add 1 tablespoon oil and the zucchini to the pot. Cook for 4 to 5 minutes, turning occasionally, until golden in spots and still firm. Transfer it to the eggplant bowl so neither vegetable dissolves during the tomato simmer.

4. Soften the peppers and onion

   Reduce the heat to medium and add the final 1 tablespoon oil, both peppers, onion and 1/2 teaspoon salt. Cook for 8 minutes, scraping the pot and stirring often, until the onion is translucent and the peppers begin to soften. Add the garlic and cook for 45 seconds.

5. Concentrate the tomato base

   Stir in the chopped tomatoes, tomato paste, thyme, bay leaf, black pepper and remaining 1/4 teaspoon salt. Bring to a lively simmer and cook uncovered for 12 to 15 minutes, stirring occasionally, until the tomatoes collapse into a glossy sauce while some red pieces remain recognizable.

6. Braise the vegetables together

   Return the eggplant and zucchini to the pot and fold gently to coat. Reduce the heat to medium-low and simmer uncovered for 10 to 12 minutes, stirring just twice, until the eggplant is creamy inside, the zucchini is tender and the pieces still hold their shape.

7. Add the olives and sharpen the finish

   Discard the bay leaf. Fold in the whole green olives and red wine vinegar and cook for 2 minutes. Remove from the heat, fold in half the basil and taste; add salt only if the olives have not seasoned the dish enough.

8. Rest and plate like the photograph

   Let the ratatouille stand uncovered for 10 minutes so the olive oil and vegetable juices settle into a cohesive sauce. Spoon it onto a wide white platter, turning several purple eggplant pieces, red tomatoes, green zucchini and whole olives upward. Scatter the remaining torn basil over the chunky vegetables and serve warm or at room temperature.

Why this works

Swaps & notes

Easy swaps

• Yellow squash can replace either zucchini, and a yellow bell pepper can replace the green one without changing the timing.
• Use one 28-ounce can of drained whole peeled tomatoes when ripe tomatoes are unavailable. Crush them into large pieces and simmer the base for 10 minutes before recombining the vegetables.
• For an olive-free version, omit the olives and add 2 tablespoons drained capers with the vinegar for a smaller but similarly briny accent.

Cook notes

• One-inch eggplant pieces shrink substantially, while slightly smaller zucchini pieces finish tender at the same time after their separate browning stages.
• Ratatouille tastes fuller after several hours, making it an unusually good make-ahead vegetable main, pasta topping or side dish.
• The chosen photograph includes whole green olives as well as distinct tomato, eggplant, zucchini and pepper pieces, so the recipe and final plating deliberately preserve each visible component.

Storage

Cool the ratatouille in shallow containers and refrigerate within 2 hours for up to 5 days. Reheat gently in a covered saucepan over medium-low, stirring occasionally, until it reaches 165°F, or serve chilled leftovers at 40°F or below. Freeze for up to 2 months; thaw overnight in the refrigerator, then simmer uncovered briefly if excess liquid separates.
