Vegetarian Eggplant Lasagna Ingredients
For the Eggplant Layers
- Eggplant – The star of the dish that replaces traditional noodles, keeping it low-carb. Substitute with zucchini if preferred.
- Olive Oil – Essential for roasting and sautéing, enhancing flavors. Avocado oil works well if you need a higher smoke point.
For the Mushroom Filling
- Mushrooms – Provides depth and an umami kick; a blend of cremini, portobello, and shiitake excels in flavor.
- Onion – Adds natural sweetness and complexity to the filling.
- Garlic – The secret ingredient that enhances the overall flavor; fresh is best.
For the Cheese Mixture
- Ricotta Cheese – Offers creaminess and structure; cottage cheese is a lighter substitute, while dairy-free cheese is perfect for vegan options.
- Parmesan Cheese – Adds richness, but nutritional yeast serves as a great vegan alternative.
- Egg – Helps bind the ricotta mixture together; opt for a flax egg if vegan.
For Assembly
- Marinara Sauce – Provides moisture and flavor; feel free to use store-bought or your homemade version.
- Mozzarella Cheese – Melts beautifully as the topping; swap for dairy-free cheese to make it vegan.
For Garnish
- Fresh Basil/Parsley – Adds a burst of freshness and color, enhancing the visual appeal.
Step‑by‑Step Instructions for Vegetarian Eggplant Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). As the oven heats, get two baking sheets ready by lining them with parchment paper or aluminum foil. This will prepare your workspace for the roasted eggplant, which will serve as the vital layers in your Vegetarian Eggplant Lasagna.
Step 2: Prepare the Eggplant
Slice the eggplant into ¼-inch thick rounds, and generously sprinkle with salt. Allow the slices to sit for 15 minutes; this salting process helps draw out excess moisture and bitterness. After 15 minutes, rinse the slices under cold water, pat them dry with paper towels, and set aside.
Step 3: Roast the Eggplant
Arrange the dried eggplant slices in a single layer on the prepared baking sheets. Drizzle with olive oil, and season with pepper and any additional spices you enjoy. Roast in the preheated oven for 20–25 minutes, flipping halfway through, until the eggplant is tender and golden-brown. This roasting time enhances the flavors for your lasagna.
Step 4: Sauté the Mushroom Filling
While the eggplant is roasting, heat a tablespoon of olive oil in a large skillet over medium heat. Add diced onion and sauté for about 3-4 minutes until translucent. Stir in minced garlic and sliced mushrooms, cooking for another 8–10 minutes until the mushrooms are browned and their moisture has cooked off. Season with oregano and fresh basil for extra flavor.
Step 5: Mix the Cheese Filling
In a mixing bowl, combine the ricotta cheese, egg, and Parmesan cheese (if using). Stir until the mixture is smooth and creamy, incorporating the fresh parsley as well. This rich cheese filling will add a delightful layer of texture and flavor to your Vegetarian Eggplant Lasagna.
Step 6: Assemble the Lasagna
Lower the oven temperature to 375°F (190°C). In a baking dish, spread a thin layer of marinara sauce across the bottom. Layer half of the roasted eggplant slices on top, followed by half of the ricotta mixture and half of the mushroom filling. Repeat to create another layer, topping with remaining marinara sauce and a generous sprinkle of mozzarella cheese.
Step 7: Bake the Lasagna
Cover the assembled lasagna with aluminum foil to retain moisture and bake in the preheated oven for 30 minutes. After this time, remove the foil to allow the cheese to brown, and bake for an additional 10–15 minutes until the cheese is melted and bubbly. Keep an eye on it for that golden finish.
Step 8: Rest and Garnish
Once baked, remove the lasagna from the oven and let it rest for about 10 minutes. This resting time allows the layers to set for easier slicing. Before serving, garnish your Vegetarian Eggplant Lasagna with fresh basil or parsley for a pop of color and an aromatic touch that will impress your family and friends.

Make Ahead Options
These Vegetarian Eggplant Lasagna layers are perfect for meal prep enthusiasts! You can assemble the entire dish up to 24 hours in advance, simply cover it tightly with plastic wrap and refrigerate. This not only saves time but allows the flavors to meld beautifully. The roasted eggplant and mushroom filling can be prepared 3 days in advance and stored separately in the fridge. To maintain the quality and prevent sogginess, avoid adding the mozzarella cheese until you are ready to bake. When you’re ready to serve, just preheat the oven to 375°F (190°C), sprinkle on the mozzarella, and bake as instructed until bubbly and golden—just as delicious as when freshly made!
How to Store and Freeze Vegetarian Eggplant Lasagna
Fridge: Store your leftover Vegetarian Eggplant Lasagna in an airtight container for up to 3 days. Reheat in the oven at 350°F for 10–15 minutes, adding a splash of marinara to keep it moist.
Freezer: To freeze, wrap the cooled vegetable lasagna tightly in plastic wrap followed by aluminum foil. It can safely be stored for up to 3 months. Thaw in the fridge overnight before baking.
Reheating: For best results, reheat individual portions in the microwave for 2–3 minutes or in the oven until thoroughly heated, around 15–20 minutes at 350°F.
Make-Ahead: Assemble the vegetarian eggplant lasagna a day in advance and keep it covered in the fridge before baking. This allows the flavors to meld beautifully!
