Ratatouille Tartine: Rustic French Vegetable Toast Recipe

A beautiful, traditional way to use the season’s best vegetables in one dish. The French word ratatouille (ra-ta-too-yuh) means “to stir up.” Classic Provençal ratatouille cooks each vegetable separately so every piece reaches its ideal texture. For a quicker weeknight version, I take a few practical shortcuts without sacrificing the flavors: summer vegetables roast and then simmer gently in olive oil with garlic and herbs. The result is silky, garlicky, herb-forward vegetables with a texture reminiscent of a confit.

I love this on a grilled slice of sourdough, but it also makes a versatile side for meats or fish, a rustic pasta sauce, or a spoonful over hot cheesy polenta. Ratatouille improves as it rests—the vegetables marinate in the olive oil and deepen in flavor. Store in the refrigerator up to 5 days, reheat gently or serve at room temperature. It’s equally delicious cold.

Ingredients

• 2 medium yellow onions, sliced into half moons
• 3 medium zucchini, cut into 1-inch pieces
• 2 medium eggplant, cut into 1-inch pieces
• 1 (14.5 oz) can petite diced stewed tomatoes, very well drained
• 3 sweet red peppers (bell peppers), seeded and thinly sliced
• 4 garlic cloves, minced or sliced
• 3 tablespoons fresh or dried rosemary, chopped
• 4 tablespoons fresh or dried thyme, chopped
• 2 bay leaves
• 1/2 cup fresh flat-leaf parsley, coarsely chopped
• Coarse salt and black pepper, to taste
• 1 cup olive oil, plus more as needed

Instructions

1. Preheat the oven to 400°F (200°C). On a large rimmed baking sheet, toss the eggplant and zucchini with 1/2 cup of the olive oil and 1 tablespoon each of the rosemary and thyme. Season with salt and pepper. Roast, turning occasionally, until the vegetables are golden and tender, about 40–45 minutes.
2. While the vegetables roast, heat the remaining 1/2 cup olive oil in a deep skillet over medium-high heat. Add the onions and garlic and cook until softened and slightly browned, about 8–10 minutes. Stir in the drained tomatoes, the remaining thyme and rosemary, the bay leaves, and the sliced red peppers. Cook until the peppers are soft, about 10–12 minutes. Taste and season with salt and pepper.
3. Add the roasted eggplant and zucchini to the skillet. Reduce the heat to medium-low and simmer, stirring occasionally, until all the vegetables are very soft and flavors meld, about 25–30 minutes.
4. Stir in the chopped parsley and cook just until heated through, about 1–2 minutes. Remove from heat.
5. Serve warm on grilled sourdough as a tartine, spooned over creamy polenta, tossed with pasta, or as a flavorful side for grilled meats or fish. Ratatouille is also excellent at room temperature or chilled.

Serving suggestions: Spoon over grilled sourdough toast for a tartine, serve with creamy polenta, use as a pasta sauce, or pair with grilled meats or fish. Leftovers are ideal tossed with pasta or folded into an omelet or frittata.

You can store ratatouille in an airtight container in the refrigerator for up to 5 days. Reheat gently on the stove or microwave, or serve cold or at room temperature.
