If you love lasagna but want a lighter, vegetable-packed version without traditional flour-based pasta sheets, this flourless vegetarian lasagna is worth trying. It is creamy, cheesy, colorful, and surprisingly satisfying.
Instead of pasta, thinly sliced zucchini and eggplant create the layers. Combined with homemade tomato sauce, ricotta, mozzarella, and Parmesan, the result is a comforting vegetarian lasagna that works beautifully for lunch or dinner.
Ingredients for Flourless Vegetarian Lasagna
For the Vegetable Layers
- 2 medium zucchini
- 1 large eggplant
- 1 tablespoon olive oil
- Salt and black pepper to taste
For the Filling
- 2 cups ricotta cheese
- 1 large egg
- 1/2 cup grated Parmesan cheese
- 1 teaspoon dried Italian seasoning
- 2 garlic cloves, minced
- 2 cups shredded mozzarella cheese
For the Tomato Sauce
- 2 cups crushed tomatoes
- 1/2 small onion, finely chopped
- 2 garlic cloves, minced
- 1 tablespoon olive oil
- 1 teaspoon dried oregano
- Salt and black pepper to taste
- Fresh basil, optional
You’ll need a baking dish, skillet, mixing bowl, knife or mandoline, and aluminum foil. Preparation takes about 25 minutes, followed by approximately 45 minutes of baking.
How to Make Flourless Vegetarian Lasagna
Preheat your oven to 400°F.
Slice the zucchini and eggplant lengthwise into thin strips. Try to keep the slices relatively even so they cook at the same rate.
Place the vegetables on a baking sheet, brush lightly with olive oil, and season with salt and black pepper.
Roast for approximately 10–15 minutes. This step is important because vegetables release a lot of moisture during baking. Removing some of that moisture helps prevent watery lasagna.
Meanwhile, prepare the sauce.
Heat olive oil in a skillet over medium heat. Add the onion and cook for 3 minutes. Add the garlic and cook for another 30 seconds.
Add the crushed tomatoes, oregano, salt, and black pepper. Simmer for about 10 minutes. Add fresh basil if desired.
In a bowl, combine the ricotta, egg, Parmesan, Italian seasoning, and minced garlic.
Reduce the oven temperature to 375°F.
Spread a thin layer of tomato sauce in a baking dish. Add a layer of roasted vegetables, followed by ricotta mixture, mozzarella, and more sauce.
Repeat the layers until all the ingredients are used, finishing with mozzarella and Parmesan.
Cover loosely with foil and bake for 25 minutes. Remove the foil and bake for another 15–20 minutes, until bubbling and golden on top.
Let the lasagna rest for 10–15 minutes before slicing. This helps the layers set and makes serving much easier.
Tips for the Best Vegetable Lasagna
Don’t skip the roasting step. Excess moisture is the biggest reason vegetable lasagna becomes watery.
You can add mushrooms, spinach, bell peppers, or roasted tomatoes to the layers.
For extra flavor, add fresh basil between the layers or a pinch of red pepper flakes to the tomato sauce.
A Lighter Version
For a lighter vegetarian lasagna, use part-skim ricotta and mozzarella and reduce the amount of cheese slightly.
You can also replace some of the ricotta with blended cottage cheese. Add spinach, mushrooms, and extra zucchini for more vegetables and fiber.
