How to Make Vegan Lasagna with Zucchini

  • Preheat the oven to 350°F. Then grease a 9×13 inch casserole dish with some oil. 
  • Prep ingredients. First, pat the tofu dry with a paper towel and set aside. Then cut dice the shallots, chop the mushrooms, and slice the zucchini lengthwise into very thin slices.
  • Make the tofu-cashew filling. Place the cashews into a food processor and process into a fine meal. Now add in the tofu, nutritional yeast, lemon juice, basil, oregano, garlic powder, and salt. Process again scraping down the sides as necessary. Add 2-4 tablespoons of water to reach the desired consistency. It should look like the photo.

  • Make the sauce. Heat oil in a large skillet over medium heat. Then add the mushrooms and shallots. Season with some salt and cook stirring occasionally until brown. Stir in the marinara sauce and cook for 2 minutes until the sauce starts to bubble.
  • Assemble the lasagna. Start with a layer of marinara sauce mixture. Then lay 3 lasagne sheets on top of the sauce. Next add a layer of the cashew-tofu mixture, followed by a layer of spinach. Last, add sliced zucchini and top with 3 slices of vegan mozzarella cheese.

  • Bake. Cover the dish with foil and place in the preheated oven. Bake for 50 minutes, then uncover the dish and broil for 10 minutes until the top is golden and the cheese is bubbly.
  • Cool slightly and serve. Once done, remove from the oven and let cool at room temperature for about 15 minutes. Slice and serve warm.

Tips and Substitutions

  • Shallots: You can also substitute with onions if needed. 
  • Marinara sauce: Use jars from the store or make homemade marinara sauce
  • Tofu: Use firm tofu for the best texture, since extra-firm will have less moisture. 
  • Nutritional yeast: This adds extra nutrients to make this a well-balanced vegan meal. 
  • Lasagna sheets: Use regular, whole-grain, or gluten-free. For a low-carb or keto version, use only zucchini or add thin slices of eggplant. 
  • Make sure to bake the dish covered at first, but broil it for a few minutes in the end for that signature golden, bubbly top.
