Vegetables
- 1 medium eggplant, sliced into thin rounds
- 1 medium zucchini, sliced into thin rounds
- 2–3 medium tomatoes, sliced into thin rounds
- 1–2 bell peppers (red, yellow or orange), sliced into thin rounds
- 1 medium onion, sliced
- 3–4 garlic cloves, minced
Seasonings & Herbs
- 3–4 tbsp olive oil, divided
- 1–2 tsp fresh thyme or rosemary (or a mix)
- Salt, to taste
- Black pepper, to taste
Optional Variations
- Grated Parmesan or crumbled goat cheese, for sprinkling before baking
- Cooked chickpeas or sliced grilled chicken, for added protein
- Red chili flakes or smoked paprika, for a spicy kick
- Alternative herbs like oregano, tarragon, or marjoram
- Prepare Your Vegetables: Wash all vegetables thoroughly. Slice the eggplant, zucchini, tomatoes, and bell peppers into thin, even rounds to ensure consistent cooking and tenderness without sogginess.
- Make the Flavorful Base: In a baking dish, spread a layer of sliced onions and minced garlic. Drizzle olive oil over them and sprinkle salt and pepper. This layer will infuse a savory foundation during baking.
- Arrange the Vegetable Layers: Alternate and overlap slices of eggplant, zucchini, tomato, and bell pepper vertically or in a circular pattern atop the onion layer. This colorful arrangement ensures even cooking and beautiful presentation.
- Season and Drizzle: Gently brush or drizzle olive oil over the arranged vegetables. Sprinkle fresh herbs like thyme or rosemary, and season with a little more salt and pepper. This will enhance flavor and promote a light caramelization.
- Bake to Perfection: Cover the baking dish loosely with aluminum foil. Bake in a preheated oven at 375°F (190°C) for about 40 minutes. Remove the foil and bake for an additional 10-15 minutes until vegetables are fully softened and edges brown slightly.
Notes
- Use uniform slicing methods like a mandoline or sharp knife for consistent cooking.
- Do not overcrowd the vegetable slices to avoid steaming; allow space for roasting.
- Add fresh basil after baking for a bright, aromatic finish.
- Choose ripe tomatoes for natural sweetness and moisture.
- Use high-quality extra virgin olive oil for the best flavor.
- Leftovers keep refrigerated in an airtight container up to 3 days, with flavors improving overnight.
- Freeze cooled ratatouille in sealed containers for up to 2 months; thaw overnight before reheating.
- Reheat gently in the oven covered with foil or on stovetop with a splash of water to retain moisture.
