Ingredients
For the Roasted Eggplant Layers
- 2 large eggplants, sliced lengthwise into ¼-inch thick slices
- 2 tablespoons olive oil
- Salt and freshly ground black pepper, to taste
For the Mushroom Filling
- 2 tablespoons olive oil
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 10 ounces mushrooms (cremini or button), finely chopped
- 1 teaspoon dried oregano
- ½ teaspoon crushed red pepper flakes (optional)
- Salt and black pepper, to taste
For the Cheese Mixture
- 1 ½ cups ricotta cheese
- ½ cup grated Parmesan cheese
- 1 egg
- 2 tablespoons chopped fresh parsley or basil
- Salt and pepper, to taste
For Assembly
- 2 cups marinara sauce (store-bought or homemade)
- 1 ½ cups shredded mozzarella cheese
- Extra Parmesan and fresh basil for garnish
Instructions
1. Prepare the Eggplant:
Preheat oven to 400°F (200°C). Line two baking sheets with parchment paper. Arrange the eggplant slices in a single layer, brush lightly with olive oil on both sides, and season with salt and pepper. Roast for 20 minutes, flipping halfway through, until tender and lightly golden. Set aside to cool slightly.
2. Cook the Mushroom Filling:
Heat olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 3 minutes. Stir in the garlic and cook for another 30 seconds until fragrant. Add mushrooms and cook for 6–8 minutes until they release their moisture and begin to brown. Season with oregano, red pepper flakes (if using), salt, and black pepper. Remove from heat and let cool slightly.
3. Make the Cheese Mixture:
In a medium bowl, mix ricotta cheese, Parmesan, egg, parsley, salt, and pepper until smooth and well combined.
4. Assemble the Lasagna:
Spread a thin layer of marinara sauce at the bottom of a 9×13-inch baking dish. Layer roasted eggplant slices to cover the bottom. Add half of the mushroom filling, followed by half of the ricotta mixture, and a sprinkle of mozzarella. Repeat the layers — sauce, eggplant, mushrooms, ricotta, mozzarella — until ingredients are used up. Finish with a final layer of sauce and mozzarella on top.
5. Bake the Lasagna:
Cover the dish loosely with foil (tent it so the cheese doesn’t stick) and bake for 25 minutes. Remove the foil and bake for another 15–20 minutes, until bubbly and golden brown.
6. Rest and Serve:
Let the lasagna rest for 10–15 minutes before slicing. Garnish with fresh basil and extra Parmesan cheese. Serve warm.

Notes
Pro Tips for Perfect Eggplant Lasagna
- Salt your eggplant: If your eggplants are older or large, sprinkle the slices with salt and let them sit for 20 minutes before roasting. This draws out excess moisture and bitterness.
- Don’t skip roasting: Roasting helps prevent soggy layers and deepens flavor. Avoid frying — it absorbs too much oil.
- Let it rest: Like any good lasagna, it firms up as it cools slightly. Cutting too soon can make it fall apart.
- Add greens: A handful of spinach or kale sautéed with the mushrooms adds extra nutrition and flavor.
- Use fresh herbs: Fresh basil or oregano elevates the flavor beautifully.
Variations to Try
1. Zucchini & Eggplant Combo:
Use a mix of zucchini and eggplant slices for a layered texture and color contrast.
2. Creamy Spinach Layer:
Mix sautéed spinach into the ricotta mixture for a creamy, green layer.
3. Vegan Version:
Swap ricotta for cashew ricotta and mozzarella for vegan cheese. Skip the egg or replace with a flax egg (1 tbsp flaxseed meal + 3 tbsp water).
4. Mediterranean Style:
Add sun-dried tomatoes, artichokes, or olives for a tangy, flavorful twist.
5. Spicy Kick:
Add a layer of roasted red peppers or increase the chili flakes in the mushroom filling.

Fun Fact: Why Eggplant Makes Such a Great Pasta Substitute
Eggplant is a star vegetable in Mediterranean cuisine, often called the “meat” of the plant world because of its hearty texture and mild, adaptable flavor. In this lasagna, the roasted slices not only mimic the structure of pasta sheets but also soak up the sauce and cheese, creating rich layers that hold together perfectly. Plus, they bring natural fiber and nutrients — a win-win for taste and health.
