A rustic French stew, this Ratatouille Recipe is loaded with eggplant, bell peppers, and zucchini. Roasted vegetables caramelize to concentrate their flavors and then rehydrate in a simple sauce made with fresh, juicy tomatoes and plenty of herbs and spices.
Preheat oven to 425 degrees. Line 2 rimmed baking sheets with parchment paper or foil for easy cleanup.
In a large bowl, add eggplant, bell pepper, squash, and zucchini. Drizzle with olive oil, 1 teaspoon salt and ½ teaspoon pepper and toss to combine.
Divide the vegetables among the two prepared baking sheets and roast until the vegetables are soft and lightly browned, about 45 minutes, stirring and rotating pans after 30 minutes of roasting time.
To make the sauce:
While the vegetables are roasting, in a Dutch oven or large saucepan over medium-high heat, heat olive oil until shimmering. Add onion and garlic and cook until softened, about 5 minutes.
Add the tomatoes to a blender or food processor and process until smooth. To the skillet with the onions and garlic, add the tomato sauce, basil, thyme, oregano, and red chili flakes, if using.
Reduce heat to medium and simmer uncovered while the vegetables finish roasting. Season to taste with salt and pepper (I like ½ teaspoon salt and ¼ teaspoon pepper).
To the pot with the sauce, stir in the roasted vegetables. Simmer 5 minutes longer to blend flavors, then garnish with fresh basil and salt and pepper to taste (I like 1/4 teaspoon salt or less). Serve with crusty bread.
Notes
Eggplant: Leave the skin on the eggplant so it can hold it's cubed shape even after roasting.
Bell pepper: Any color bell pepper will work in this recipe.
Squash and zucchini: Mix and match or use just one variety, but aim for a pound total.
Tomatoes: Substitute any kind of tomato you like or that looks ripe and juicy. In a pinch, substitute one (28-oz.) can diced tomatoes.
