How to Make Vegan Zucchini Lasagna
Step 1: Prep the Zucchini
Slice your zucchini lengthwise using a mandoline or sharp knife. Lay the slices out on paper towels or a baking sheet, sprinkle with salt, and let them sweat for 15–20 minutes. This removes excess moisture and prevents a watery lasagna. Pat dry before layering.
Step 2: Make Vegan Ricotta
In a blender or food processor, combine soaked cashews, lemon juice, garlic, nutritional yeast, salt, and water. Blend until creamy and smooth. Add more water if needed for a spreadable consistency. Stir in spinach or basil if using.
Step 3: Cook the Sauce
Heat olive oil in a skillet over medium heat. Add onion and cook until soft, then add garlic and sauté for another minute. Stir in crushed tomatoes, tomato paste, and seasonings. Simmer for 10–15 minutes. Adjust salt and pepper to taste.
Step 4: Prepare the Lentils
Toss cooked lentils with balsamic vinegar, salt, and pepper. This adds depth and umami to the dish.
Step 5: Assemble the Lasagna
In a 9×13-inch baking dish, start with a layer of tomato sauce. Add a single layer of zucchini slices, followed by dollops of ricotta and a sprinkle of lentils. Repeat the layers until ingredients are used up, finishing with sauce and vegan cheese on top.
Step 6: Bake
Cover the lasagna with foil and bake at 375°F (190°C) for 25 minutes. Uncover and bake another 15–20 minutes until bubbling and golden on top. Let it rest for 10–15 minutes before slicing — this helps it hold together beautifully.
Tips for the Perfect Vegan Zucchini Lasagna
- Sweat the zucchini well. Don’t skip this step! It helps avoid excess water in your lasagna.
- Use a mandoline for even slices. Uniform thickness ensures even cooking.
- Let it rest after baking. Just like traditional lasagna, letting it sit allows the layers to firm up.
- Add extra veggies. Mushrooms, spinach, or eggplant work well in the layers for added texture and flavor.

Make It a Meal
While this Vegan Zucchini Lasagna is filling enough on its own, it pairs beautifully with a few simple sides or appetizers:
- A crisp green salad with lemon vinaigrette
- Goat Cheese Appetizer Spread served with seeded crackers (just swap for a vegan cheese)
- Garlic Bread Ritz Bits for a fun, crunchy side (use vegan butter!)
For dessert, you can’t go wrong with something indulgent like White Chocolate Raspberry Cheesecake Balls. If you’re going for a fully vegan menu, substitute with vegan white chocolate — just as delicious and totally plant-based.
Storage & Meal Prep
One of the best parts of this lasagna is how well it keeps. Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual servings in the microwave or oven.
It also freezes well. Assemble the lasagna in a freezer-safe dish, cover tightly, and freeze before baking. When ready to eat, bake from frozen at 375°F for 45–60 minutes, covered with foil.
This makes it a great addition to your weekly meal prep — just like our popular Taco Rice Bowl or Chicken Rice Bowls with Garlic Sauce.
Nutritional Benefits
Zucchini is rich in antioxidants, vitamin A, and fiber. Cashews provide healthy fats and protein, while lentils add a powerful dose of plant-based iron, folate, and more protein. The whole dish is gluten-free, dairy-free, and low in carbohydrates, making it suitable for a wide range of dietary needs.
This recipe is a fantastic alternative for those trying to limit refined carbs or gluten — just like our nourishing Sun-Dried Tomato Spinach Risotto, which also highlights wholesome, nutrient-rich ingredients in a comforting form.
