One Pot Vegan Lasagna Soup

This one pot vegan lasagna soup recipe offers all the rich flavor of actual lasagna, without all the work! The secret to making this vegan version of the viral TikTok soup rich and creamy is a simple cashew cream that gets stirred into the soup at the end.

If you spend any time on TikTok (guilty!), you’ve likely come across the viral lasagna soup recipe that was making the rounds this winter. The original version of the recipe isn’t vegan, so I made it my mission to create a plant-based version that was just as good. This vegan lasagna soup made with simple ingredients has gotten rave reviews from family and friends!

This vegan soup gets extra creaminess without dairy from a quick cashew cream made in the blender. You don’t have to soak cashews all night long to make it either! I always do a quick soak in boiling water for my cashew cream and I works great every time.

Ingredients You’ll Need

• Veggies (onion, green bell pepper): we’re keeping this delicious soup simple with just onion and green bell pepper for some flavor and fiber. You can use red onion if you’d like and any color bell pepper can be used (red bell pepper is great!).
• Marinara Sauce: rather than canned tomato sauce or diced tomatoes, we’re using a marinara sauce for this vegan lasagna soup recipe. Not only does it add necessary moisture, but it’s also pre-seasoned with herbs and spices so it will give your soup the classic lasagna flavors. Since it’s going to add a lot of flavor to the soup, choose a higher-quality marinara sauce. (You could also use this homemade small batch marinara!)
• Vegan Ground Sausage: use any brand of vegan ground sausage that you prefer. We usually use Upton’s ground Italian seitan, but this would also be good with Beyond Meat’s Italian sausage if you want a richer option that is also gluten free.
• White Beans: for additional texture and fiber, we also added a can of white beans to this lasagna soup. If you aren’t using a plant-based sausage, I’d recommend adding 2 cans of white beans instead of just one for a more filling soup. If you don’t want to use beans, cooked brown lentils would also work well in this deconstructed lasagna soup.
• Lasagna Noodles: no need to buy no boil lasagna noodles for this one pot lasagna soup. (Although, if you have them – the do work well!) You’ll break the noodles apart into bite sized pieces for the soup. The broken lasagna noodles get cooked in the same pot with the soup so they soak up so much delicious flavor. Of course, you can use any pasta shape you like – not just lasagna noodles. 
• Vegan Cheese: for additional creaminess, we like to stir in some shredded vegan mozzarella cheese and some vegan parmesan.
• Cashews: the TikTok lasagna soup calls for heavy cream so we replaced it with cashew cream instead. It’s super simple to make and levels up this creamy vegan lasagna soup.

Variations and Substitutions

• Add more veggies: if you love lots of vegetables in your soup, feel free to add more. We recommend chopped zucchini, cremini mushrooms, fresh spinach, or kale.
• Make it gluten free: use gluten-free lasagna noodles and a gluten free vegan sausage or plant-based ground/veggie crumbles like the frozen ground be’f from Gardein or this vegan ground from Abbot’s.
• Make it vegetarian: if you’re feeding vegetarian eaters, you can use regular mozzarella and heavy cream instead of he cashew cream.
• Make it soy free: the vegan ground meat that we typically use is seitan so it is soy-free already. If you’d rather skip the vegan meat, just use 2 cans of white beans to the recipe instead of one. Use a soy free vegan cheese too.

How to Make the Best Vegan Lasagna Soup Recipe

Step One: Add the cashews to a bowl and cover with boiling water. Let sit for 20-30 minutes to soften while you prepare the soup. Drain the cashews and add them to a blender or food processor with 1 cup of water. Blitz until smooth.

What to Serve with this One Pot Lasagna Soup

Like a traditional slice of lasagna, this lasagna soup is pretty filling on it’s own as a one-pot meal, but if you want to pair it with something – here are a few ideas for you.

• Salad: soup and salad are a classic pairing. These are our favorite salads to serve with this soup: vegan Italian chopped salad, kale Caesar salad, and white bean pesto salad with arugula.
• Bread: this delicious vegan lasagna soup recipe is great for dipping some toasted sourdough, rolls, or garlic bread.
• Pesto: garnish your soup with some homemade pesto (or store-bought!) for some extra basil flavor.
• Vegan Ricotta: if you want an indulgent bowl of soup, add a dollop of dairy-free ricotta on top. 

Storage

Fridge: allow soup to cool and store in an airtight container in the refrigerator for up to 3-4 days. Reheat in a saucepan on the stovetop or for a few minutes in the microwave.

Freezer: store leftover soup in an airtight container (I like to portion individual servings into separate containers). Freeze for up 3 months. Allow soup to thaw in the fridge overnight before reheating on the stovetop or in the microwave.
