Recommended Ingredients and Equipment
This vegan lasagna is so flavorful. It is packed with homemade Bechemel and Marinara Sauce, veggies, and homemade cheeses. And it's made without processed foods. It's a vegan lasagna that uses no store bought cheeses or sauces, relying on only wholesome, nutrient-packed foods.
Here is everything you need.
Ingredients & Substitutions
- Lasagna Noodles - If you are looking for a gluten-free option, I like this brand of gluten-free pasta. (<<affiliate link)
- Cashew Ricotta - This homemade vegan ricotta is a blend of raw cashews, water, garlic, nutritional yeast, lemon juice, and salt. If you want to save on time, you could buy vegan ricotta at the store. I recommend Kite Hill Almond Ricotta.
- Olive Oil
- Button Mushrooms
- Spinach - I recommend fresh spinach but you can use frozen if that's what you have on hand.
- Marinara Sauce - Use either store bought or homemade.
- Vegan Parmesan - I recommend Violife parmesan. It is creamy, melty, and tastes exactly how I remember parmesan to taste. If you don’t have access to Violife, you can make your own parmesan.
- Vegan Butter - Look for a high-quality non-hydrogenated vegan butter. I recommend either Earth Balance or Miyoko’s.
- Fresh Herbs - You will need fresh oregano and thyme. If you only have access to dried herbs, use ½ teaspoon of both.
- All-Purpose Flour
- Non-Dairy Milk - You can use any neutral flavored non-dairy milk. I recommend soy or cashew. Make sure to use unsweetened milk.
- Spices - You will need nutmeg, salt, and pepper.

How to Make Vegan Lasagna
Step One - Make the Vegan Ricotta
This vegan ricotta is made from blending up cashews, nutritional yeast, garlic, and lemon juice in a food processor until it resembles ricotta cheese.
If you're looking to save time, this ricotta can be made a day or two in advance. To store it, keep it in an airtight container in the refrigerator until ready to use. Because there is a lot of multitasking required for this lasagna, I do recommend you make the vegan ricotta in advance.
Time Saving: You could also use store-bought vegan ricotta. Kite Hill has a delicious almond based ricotta that I recommend.
Step Two - Make the Bechamel Sauce
The next step is to make the vegan Bechamel Sauce. Bechamel, or white sauce, is a classic French sauce made from butter, flour, and milk. Often fresh herbs and seasonings are added to the bechamel for flavoring.
To make the bechamel, you need to make a roux with flour and butter. Once the flour starts to cook, add warm milk (and any possible seasonings and herbs) and cook the sauce until it is thick and creamy.
As you can imagine, traditional Bechamel is not vegan. However, it's an easy sauce to make vegan. All you need to swap out is dairy butter for vegan butter. I recommend Miyoko's Cultured Vegan Butter and use non-dairy milk. For the milk, make sure to buy unsweetened and I recommend either soy, cashew, or oat for their thickness.
Step Three - Sauté the Vegetables
This part is easy! In a large skillet, sauté the mushrooms until they are golden brown and fragrant. Add the spinach and mix together until it has begun to wilt.
Step Four - Assemble and Bake
Now, with everything ready, it's time to assemble the lasagna. When assembling this recipe, you want to find a pattern. This is how I do it
- Sauce. For this recipe, I mix the marinara sauce with bechamel sauce. This gives me the classic tomato sauce taste while mixing in a bit of the creamy cheesiness of traditional lasagna.
- Noodles. Add a layer of freshly boiled (or no boil) lasagna noodles so that they are slightly overlapping.
- Veggies. Top with half of the mushroom/spinach mixture.
- Cheese. Drop half of the cashew ricotta in dollops over the top (see photo below)
Now repeat layers 1-4! Top with one more layer of noodles and the remaining sauce and you're ready to bake!
Serving and Storing
Once out of the oven, let the lasagna cool 15 minutes before serving. Serve it with fresh herbs and vegan parmesan alongside artisan bread and a big salad
Store leftover lasagna in an airtight container in the refrigerator for up to 3 days. You can also freeze this recipe for up to 3 months. When you are ready to eat it, let it thaw completely in the refrigerator overnight. Then cook it according to the instructions below.
Make in Advance
You can make this recipe and then, rather than baking the lasagna, wrap it in plastic wrap and place it in the freezer. For best results, chill the lasagna first in the refrigerator for a couple of hours so that when you are ready to place it in the freezer, it will freeze quicker. This reduces the chance of freezer burn.

Vegan Bechamel Sauce
- 3 tablespoon unsalted butter
- 2 cloves garlic, minced
- 1 sprig of oregano and thyme, de-stemmed and minced
- 3 tablespoon all-purpose flour
- 1 ¾ cup unsweetened non-dairy milk
- pinch of nutmeg
- salt and pepper, to taste
- First, make the cashew ricotta. This can be done a day or two in advance.
- While the noodles are boiling, make the Bechamel Sauce. To make the sauce, heat vegan butter in a medium saucepan over medium-high heat. Once butter is melted, add flour and stir over heat for 3-4 minutes, until the mixture is smooth and golden-brown. In another pot, bring milk, minced garlic, herbs, nutmeg, and salt to a boil. Add hot milk to butter/flour mixture in 3 batches. Bring to a boil, whisking often, then reduce heat to a simmer. Cook for 10 minutes, whisking constantly. Once thick and creamy, remove from heat and set aside. The sauce will continue to thicken as it cools.
- Heat up olive oil in a large skillet over medium heat. Add mushrooms and sauté, stirring occasionally, until golden brown. Stir in spinach until spinach has wilted and shrunk to about 50% it's original size. Remove from heat and set aside.
- To assemble the lasagna, pour about ⅓ cup of bechamel sauce and ⅓ cup of marinara sauce on the bottom of a 9x13 casserole dish and spread evenly. Lay down a layer of noodles. Add a layer of the mushroom/spinach mixture and top with ½ of the cashew ricotta, evenly dropping them in 1 tablespoon-size pieces. Top this with more bechamel and marinara sauce and repeat the pattern one full time. Top with the 3rd layer of noodles and final layer of sauces. Top with vegan parmesan, if using.
- Cover in foil and bake for 40-50 minutes until the lasagna has started to bubble up. Remove from heat and let cool 15 minutes before slicing. Top with vegan parmesan cheese and/or fresh oregano and serve.
