Ingredients

  • 2 medium zucchinis, sliced into thin rounds
  • 1 medium eggplant, sliced into thin rounds
  • 2 bell peppers (red and yellow), sliced into strips
  • 4 large tomatoes, diced
  • 1 large onion, finely chopped
  • 4 cloves garlic, minced
  • 3 tablespoons olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1 teaspoon dried basil
  • Salt and freshly ground black pepper, to taste
  • Fresh basil leaves for garnish
  • 1 tablespoon tomato paste (optional, for richer flavor)

Equipment

  • Large skillet or sauté pan
  • Sharp knife for slicing vegetables
  • Cutting board
  • Wooden spoon or spatula
  • Large baking dish or casserole dish
  • Aluminum foil (optional, for covering)
  • Measuring spoons

Instructions

  1. Prepare the vegetables. Wash and slice the zucchini, eggplant, and bell peppers into thin rounds or strips. Dice the tomatoes, finely chop the onion, and mince the garlic cloves.
  2. Sauté the aromatics. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the onion and garlic, cooking until soft and fragrant, about 3-4 minutes.
  3. Add tomatoes and herbs. Stir in the diced tomatoes, tomato paste (if using), dried thyme, rosemary, and basil. Season with salt and pepper. Let this simmer gently for 10 minutes until the tomatoes break down and form a sauce.
  4. Layer the vegetables. Preheat your oven to 375°F (190°C). In a large baking dish, spread a thin layer of the tomato sauce on the bottom. Arrange the zucchini, eggplant, and bell pepper slices in an alternating pattern over the sauce, creating a beautiful layered effect.
  5. Drizzle and season. Pour the remaining olive oil evenly over the layered vegetables. Season with a pinch of salt and pepper to enhance the flavors.
  6. Bake the ratatouille. Cover the baking dish with aluminum foil and bake for 30 minutes. Then, remove the foil and bake for an additional 15-20 minutes, or until the vegetables are tender and lightly browned on top.
  7. Garnish and serve. Remove from the oven and let it cool slightly. Garnish with fresh basil leaves before serving.

Tips & Variations

For a gluten-free, grain-free option, serve ratatouille on its own or with cauliflower rice instead of bread or pasta.

  • Make it a one-pot meal: Add cooked chickpeas or white beans for extra protein and heartiness.
  • Use fresh herbs: If you have fresh thyme, rosemary, or basil on hand, swap out the dried for a more vibrant flavor.
  • Try different vegetables: Feel free to add mushrooms, carrots, or even potatoes for variation.
  • Slow cooker option: Layer the vegetables and sauce in a slow cooker and cook on low for 4-5 hours for a hands-off approach.
  • Presentation tip: For a classic look, arrange the vegetables in tight concentric circles. For a rustic feel, toss everything together and bake.
