This creamy vegan mushroom lasagne is a sophisticated twist on a classic Italian favourite. By replacing traditional dairy with a velvety cashew nut cream and umami-rich mushrooms, this dish achieves a luxurious texture that will satisfy vegans and meat-eaters alike. The earthy notes of thyme and garlic perfectly complement the savoury marinara sauce, while fresh spinach adds a punch of colour and nutrients to every forkful.

How to make Creamy Vegan Mushroom Lasagne
Back to contentsPreheat the oven to 350ºF.
In a large skillet, heat a glug of oil or veggie broth over medium. When the pan is hot, add the garlic and sauté until it becomes fragrant. This will take about a minute. Add the mushrooms, tamari, and thyme. Cook, stirring every minute or so, for 6 to 8 minutes or until the mushrooms release their water and a little broth starts to form.
Combine the cashews and veggie broth in a high-speed blender and blend until the mixture is completely smooth. This might take up to 5 minutes, depending on the speed and power of your blender. Pour the cashew sauce into the pan with the mushrooms. Reduce the heat to medium-low and simmer for a couple minutes to let the sauce thicken, stirring frequently. Throw in the spinach and stir for another minute.
Prepare the lasagne noodles according to the package instructions. Make sure to do this after your mushroom sauce is ready to go, so the noodles don't sit for too long and start sticking together.
Spread a third of the marinara sauce on the bottom of an 8-by-11-inch baking dish. Add a layer of noodles. Cover the noodles with half of the mushroom cream. Add a layer of noodles. Use another third of the marinara to cover these noodles. Add the remaining mushroom cream. Add the last layer of noodles and cover it with the remaining marinara sauce.
Cover the lasagne with aluminum foil and bake for 30 minutes. Remove the foil, add a sprinkle of nutritional yeast over the top, if you like, and bake for another 15 minutes. Let the lasagne rest for 5 minutes before serving.
