The Easiest Vegan Lasagna Recipe

By Loving It Vegan

🔪Prep Time: 45 mins

👩‍🍳Cook Time: 30 mins


3 Packs Button Mushrooms (26.5oz / 750g in total)

2 Tbsp Soy Sauce

3 Cans (14oz/400g each) Chopped Tomato (if it has other flavorings added to it like basil, oregano or other herbs, this is great too)

Sea Salt and Black Pepper (To Taste)

6 Tbsp Olive Oil

5 Tbsp All Purpose Flour

4 cups (960ml) Soy Milk (or other non-dairy milk)

2 tsp Prepared Yellow Mustard

Salt and Black Pepper (to taste)

Spinach Lasagna Sheets (Oven Ready)*

Sliced Tomato

Vegan Cheese Slices

Black Pepper


1Slice the mushrooms and then add to a pot with 2 Tbsp Soy Sauce.

2Sauté the mushrooms in the soy sauce for a minute. Then cover the pot and leave on medium heat until the mushrooms have released their water.

3Then remove the lid from the pot and let some of the water cook off.

4When most of the mushroom water has cooked off, add the 3 cans of chopped tomatoes and bring to a simmer.

5Turn down the heat and allow to simmer for a few minutes and then add sea salt and black pepper to taste. It’s important that your sauce isn’t too thin by the time you use it, so let it cook off a bit and simmer down before you use it.

6Prepare your white sauce.

7Add the oil to a pot and turn to medium high.

8As the oil is heating, sift your flour into a bowl.

9When the oil is hot (but not sizzling) add the flour all at once and stirring continuously fry the flour in the oil for a bit, stirring vigorously.

10If it starts to stick at any point, then turn down your heat.

11Then add the soy milk all at once and stir continuously until it reaches the desired thickness.

12This will usually be a few minutes after it has reached boiling point.

13Bear in mind that the white sauce will continue to thicken after it is removed from the heat.

14When the white sauce is a nice thickness, remove from heat, and add salt, black pepper and 2 tsp yellow mustard.

15Taste test to make sure it has enough salt/pepper.

16When both sauces are ready, pre-heat the oven to 430°F (220°C).

17Layer the tomato and white sauce with spinach lasagna noodles in an oven safe rectangular dish (9×13).

18Start with a layer of tomato sauce, then a layer of spinach lasagna, then tomato sauce followed by white sauce, then spinach lasagna and repeat. End off with a layer of white sauce on the top and finish off with a layer of vegan cheese slices (we used vegan mozzarella slices) and then finish off with sliced tomato and a sprinkle of salt and black pepper.

19The layers would go roughly as follows:

20Layer of Tomato Sauce

21Layer of spinach lasagna noodles

22Layer of tomato sauce

23Layer of white sauce

24Layer of spinach lasagna noodles

25Layer of tomato sauce

26Layer of white sauce

27Layer of spinach lasagna noodles

28Layer of tomato sauce

29Layer of spinach lasagna noodles

30Layer of white sauce

31Layer of vegan cheese slices

32Layer of sliced tomato

33Sprinkle of black pepper on top.

34Place into the oven and bake, uncovered, for 30 minutes. Allow to cool for at least 10 minutes before serving.
