Scale
Vegetables
- 1 yellow onion, thinly sliced (170g, 1¼ cup)
- 1 eggplant, thinly sliced (about 1 lb, 450g, 3½ cups)
- 1 zucchini, thinly sliced (about ½ lb, 227g, 2 cups)
- 1 yellow squash, thinly sliced (about ½ lb, 227g, 2 cups)
- 3 Roma tomatoes, thinly sliced (360g, 2½ cups)
Other Ingredients
- 1 cup marinara sauce
- 1 Tbsp olive oil
- ½ tsp dried basil
- ½ tsp dried oregano
- ⅛ tsp black pepper, freshly cracked
- ⅛ tsp salt
- 1 cup shredded mozzarella cheese
- 1 Tbsp fresh parsley, chopped (optional)
Instructions
- Preheat and prepare ingredients: Gather all ingredients and preheat your oven to 400ºF (200ºC).
- Slice vegetables: Thinly slice the yellow onion. Slice the eggplant, zucchini, yellow squash, and tomatoes into ⅛-inch thick slices. For pieces with a larger diameter, cut into half-rounds to ensure even layering.
- Spread marinara and onions: Pour the marinara sauce into the bottom of a large casserole dish. Evenly sprinkle the sliced onions over the sauce.
- Arrange the vegetables: Start lining up the sliced eggplant, zucchini, yellow squash, and tomatoes vertically in the dish in an alternating pattern until all are arranged.
- Season and oil: Drizzle the olive oil over the arranged vegetables. Sprinkle the dried basil, oregano, salt, and freshly cracked black pepper evenly on top.
- Roast the vegetables: Place the casserole dish into the preheated oven and roast for 40 minutes, allowing the vegetables to soften and flavors to meld.
- Add cheese and finish roasting: Remove the dish from the oven and sprinkle shredded mozzarella evenly on top. Return to the oven and roast for an additional 5 minutes, until the cheese is melted and creamy.
- Garnish and serve: After roasting, sprinkle freshly chopped parsley over the ratatouille. Serve hot as a main or side dish.
Notes
- Marinara sauce: You can use any marinara sauce you like. Store-bought marinara makes this recipe quick and easy, while homemade marinara adds richer flavor and customization options.
- Vegetable size: Try to choose vegetables of similar diameter to facilitate neat and even layering for the best presentation.
