Cheese Filling
- 2 cups ricotta cheese
- 2 cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 large egg
- 2 tablespoons chopped fresh basil
- 1 tablespoon chopped fresh parsley
- 1 teaspoon garlic powder
Tomato Sauce
- 3 cups marinara sauce
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- ½ teaspoon dried oregano
- ½ teaspoon dried thyme
Equipment

- Baking sheets
- Parchment paper

- Pastry brush
- Sharp knife
- Aluminum foil
Instructions
Step 1: Roast the Vegetables
Preheat the oven to 400°F (200°C). Arrange the zucchini and eggplant slices on parchment-lined baking sheets. Brush lightly with olive oil and season with salt and pepper. Roast for 15 minutes, turning halfway through, until slightly tender. Remove and let cool.
Step 2: Prepare the Cheese Mixture
In a medium bowl, combine the ricotta, egg, Parmesan, basil, parsley, garlic powder, and half of the mozzarella cheese. Stir until smooth and well combined.
Step 3: Prepare the Sauce
In a saucepan over medium heat, combine the marinara sauce, garlic, Italian seasoning, oregano, and thyme. Simmer for 5 minutes, stirring occasionally to blend the flavors.
Step 4: Assemble the Lasagna
Lightly grease the baking dish. Spread a thin layer of tomato sauce on the bottom. Layer roasted zucchini, followed by ricotta mixture, tomato slices, more sauce, and roasted eggplant. Repeat the layers until all ingredients are used, finishing with tomato sauce and the remaining mozzarella and Parmesan cheese.
Step 5: Bake
Cover the baking dish with foil and bake at 375°F (190°C) for 35 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is melted, golden, and bubbling.
Step 6: Rest and Serve
Remove the lasagna from the oven and let it rest for 15 minutes before slicing. This resting time allows the layers to set, making it easier to serve.
Tips for Success
- Roasting the vegetables beforehand helps reduce excess moisture.
- Slice the vegetables evenly for uniform cooking.
- Fresh basil and parsley provide the brightest flavor.
- Let the lasagna rest before cutting to prevent it from falling apart.
- For additional protein, add cooked ground turkey or lean beef between the layers.
- A mandoline slicer makes creating evenly sized vegetable slices quick and easy.
Serving Suggestions
Pair this noodle-less lasagna with:
- Mixed green salad
- Garlic roasted broccoli
- Sautéed green beans
- Roasted asparagus
- Cauliflower rice
- Garlic mushrooms
- Fresh basil garnish
- Balsamic glaze drizzle
This dish is hearty enough to serve as a complete meal or alongside a light vegetable side.
Storage
Store leftover lasagna in an airtight container in the refrigerator for up to 4 days.
To freeze, wrap individual portions tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat individual servings in the microwave for 2–3 minutes or warm the entire casserole in a 350°F (175°C) oven for about 20 minutes, covered with foil to retain moisture.
Recipe Notes
Noodle-less Ratatouille Lasagna is an excellent option for anyone seeking a lighter version of traditional lasagna without sacrificing flavor. The roasted vegetables provide structure while adding natural sweetness and a satisfying texture. The combination of zucchini, eggplant, tomatoes, aromatic herbs, and creamy cheeses creates a comforting meal that celebrates fresh ingredients.
For extra richness, mix a small amount of pesto into the ricotta filling. If you enjoy a bit of spice, add a pinch of crushed red pepper flakes to the tomato sauce. This recipe is also highly adaptable—yellow squash, roasted bell peppers, or spinach can be added to the layers for even more variety and nutrition.
Because the vegetables release less water after roasting, the finished lasagna slices neatly and holds together beautifully, making it an excellent choice for entertaining or meal prep.
