Ingredients Overview
This lasagna comes together with only eight core ingredients, chosen for both nutrition and flavor. Here’s what you’ll need:
Vegan Ricotta Options
- 3 cups raw macadamia nuts (or soaked blanched almonds)
- OR 1 block (16 oz) extra-firm tofu, drained and pressed dry for a lighter option
- 2 tablespoons nutritional yeast (for cheesy, umami flavor)
- 1/2 cup fresh basil, finely chopped
- 2 teaspoons dried oregano
- Juice of 1 medium lemon (about 2 tablespoons) for brightness
- 1 tablespoon extra virgin olive oil (optional, adds richness)
- 1 teaspoon sea salt + pinch black pepper
- 1/2 cup water (more as needed for texture; use less if making tofu ricotta)
- 1/4 cup vegan parmesan cheese (optional, plus extra for topping)
The Lasagna Base
- 1 (28-ounce) jar favorite marinara sauce
- Choose organic, unsweetened tomato basil or your preferred red sauce.
- 3 medium zucchini squash
- Thinly sliced lengthwise with a mandolin for even layers. Eggplant can be substituted if desired.
How to Make Vegan Ricotta Cheese
The velvety vegan ricotta is the heart of this lasagna. You can make it with nuts for a classic, rich feel, or with tofu for a lighter, high-protein twist. Here’s how to whip up this dairy-free delight:
- Soak the nuts (if using macadamia or almonds): Cover with hot water and soak at least 1 hour (or overnight for perfectly smooth ricotta).
- Blend: In a food processor or blender, combine nuts (or pressed tofu), nutritional yeast, basil, oregano, lemon juice, olive oil (if using), sea salt, pepper, and water. Blend until smooth and creamy, scraping down the sides as needed.
- Adjust consistency with more water or more nuts/tofu as desired. Taste and adjust flavor—more salt, basil, or nutritional yeast as you like.
Tip: Add extra vegan parmesan for extra tang and creaminess.
How to Assemble Zucchini Lasagna
This recipe is all about simple layering. Here’s what to do:
- Preheat your oven to 375°F (190°C).
- Prepare the zucchini noodles: Trim the ends and use a mandolin or sharp knife to cut the zucchini into thin strips, about 1/8-inch thick. No need to peel, but blot moisture with kitchen towels, which helps prevent excess water in your lasagna.
- Assemble:
- Spread a thin layer of marinara sauce on the bottom of a 9×13-inch (or similar) baking dish.
- Add a single layer of zucchini strips.
- Spread a generous layer of vegan ricotta over the zucchini.
- Add another layer of marinara sauce.
- Repeat the layering—zucchini, ricotta, and sauce—until all ingredients are used, finishing with a layer of sauce and optional sprinkle of vegan parmesan.
- Bake: Cover with foil and bake for 45 minutes. Uncover and bake for another 15-20 minutes, or until bubbling and the top is golden.
- Rest: Let lasagna cool for at least 15-20 minutes before slicing—this step helps it hold together.
Tips for Perfect Zucchini Lasagna
- Prevent sogginess: After slicing the zucchini, sprinkle lightly with salt and let sit for 10 minutes. Blot with towels to remove excess moisture.
- Zucchini thickness: Aim for evenly sliced noodles for best texture.
- Let it rest: Allowing the lasagna to cool and set before cutting ensures beautiful, solid servings.
- Customize: Add in layers of sautéed mushrooms, spinach, or lentils for extra flavor and nutrition.
Ingredient Substitutions & Variations
This versatile recipe welcomes adaptations. Here are some ideas:

Frequently Asked Questions
What are the benefits of using zucchini noodles in lasagna?
Zucchini noodles reduce carbs, are gluten-free, add more vegetables to your meal, and yield a lighter casserole without sacrificing satisfaction.

Salt and blot your zucchini slices thoroughly before layering, and allow the baked lasagna to rest before cutting. Baking uncovered for the last portion can also help evaporate excess moisture.
