Ratatouille recipe by The Culinary Institute of America



Makes 10 Servings

  • 1/2 cup olive oil
  • 5 1/2 cups (about 1 pound, 8 ounces) onions, medium dice
  • 1 clove garlic, chopped
  • 2 red peppers, seeds and ribs removed, medium dice
  • 2 medium-sized eggplant, skin on, medium dice
  • 2 medium-sized zucchini, medium dice
  • 2 yellow squash, medium dice
  • 8 Roma or plum tomatoes, coarsely chopped
  • 1 1/2 tablespoons kosher salt
  • 1 teaspoon freshly ground black pepper
  • 1 tablespoon chopped thyme
  • 2 tablespoons chopped basil
  • 2 teaspoons chopped oregano


  1. Heat the oil in a large pot over medium heat. Add the onions and sauté until translucent, 4 to 5 minutes. Add the garlic and sauté until soft, about 1 minute.
  2. Adjust the heat to low and add the vegetables in order of required cooking time: peppers, eggplant, zucchini, yellow squash, and tomatoes, cooking each until softened, 2 to 3 minutes, before adding the next.
  3. Cover the pot and cook until the vegetables are tender, moist but not soupy, and flavorful, about 20 minutes. Stir in the salt, pepper, thyme, basil, and oregano. Serve immediately or chill for future use.
