Easy creamy lasagna soup with a tomato-cream base is absolutely delicious and total comfort food. The lasagna sheets cook with the rest of the soup, so this is an easy, one-pan meal!

I make this thick and creamy lasagna soup in a saucepan, cooking the lasagna sheets together in a flavorful broth with flavors of garlic, mushroom, and Italian herbs. Once the lasagna sheets are al dente, mix in tomato puree and non-dairy sour cream.

Then, top the whole thing with melty vegan cheese, veggie grounds or lentils, and basil and broil it to melt the cheese and cook the veggie grounds all at the same time!

If you don’t want to broil it, that’s fine! You can just cook the veggie grounds on a skillet for a few minutes, and then sprinkle them onto the creamy lasagna soup along with some vegan cheese and cover the pan. The hot soup and the steam in the closed pan will melt the vegan cheese beautifully.

Either way, this soup is rich and creamy with delicious Italian flavors. It’s all of the amazing textures and flavors of lasagna in soup form! You all love my easy instant pot lasagna soup with red lentils. You’ll love this tomato cream sauce lasagna soup as well! It needs just 1 pan, everyday ingredients and is super comforting.

Serve this with some nice toasted sourdough, garlic bread, or whichever vegan bread or flatbread that you like.

Ingredients 
 

For the Soup

  • 2 teaspoon extra virgin olive oil
  • 1/2 cup chopped onion
  • 3 cloves garlic, minced
  • 2 ounces sliced mushrooms, or more to taste. Use white, cremini, baby portobello, or any other type that you like.
  • 1 teaspoon balsamic vinegar
  • 4 cups water, or stock
  • 1 teaspoon Italian herb blend
  • 1 teaspoon dried basil
  • 1 teaspoon onion powder
  • 1/4 teaspoon pepper flakes
  • 1/2 teaspoon salt, or to taste
  • 1/2 teaspoon black pepper
  • 1 tablespoon nutritional yeast, (optional)
  • 6 lasagna sheets, broken into pieces, use gluten-free, if needed.
  • 5 ounces canned tomato puree, or tomato sauce
  • 1/4 cup vegan parmesan
  • 1/3 cup non-dairy sour cream, or non-dairy yogurt, or use a 1/2 cup of cashew cream. You can use more for creamier.

For Topping

  • 1/4 cup vegan mozzarella, or more, to taste
  • 2 ounces veggie grounds, or use lentils or chopped vegan meat sub or finely chopped walnuts
  • 1/2 teaspoon dried basil
  • 1/2 teaspoon Tajin seasoning, or Cajun spice or pepper flakes

Instructions 

  • Heat a large saucepan or somewhat deep skillet over medium heat. Add the olive oil, and once the oil is hot, add the onion and garlic and a good pinch of salt. Cook until the onion is starting to turn golden, adding splashes of water in between to help the onion cook evenly, 4 to 8 minutes.
  • Then, mix in the mushrooms and balsamic vinegar and another pinch of salt, and cook for a minute. Now, mix in the water or stock, dried herbs and spices, pepper flakes, salt, pepper, and nutritional yeast. Bring to a boil, then add the broken lasagna sheets. Mix well, then partially cover the pan, and cook for 14 to 18 minutes, or until the lasagna sheets are al dente
  • Mix in the tomato puree, vegan parmesan, and non-dairy sour cream. Bring to a boil again, then taste and adjust flavor and also check that the lasagna sheets are cooked. If they’re not done to your preference, cover the pan and continue to cook for another few minutes.
  • You can do this next step either with the soup in an ovenproof dish or ladled into individual, oven-safe bowls. Top the soup with the vegan mozzarella, basil, Tajin, and veggie crumbles, and put it under the broiler for 2 to 4 minutes for the cheese to melt and start to get a little golden, then serve. If you don’t want to put the pan into the oven, then cook your veggie grounds on a skillet for a few minutes with a pinch of salt and the Tajin or pepper flakes and dried basil. Mix and cook until the veggie grounds are crisp to your preference, then sprinkle over the hot soup in the pot. Top it with the vegan mozzarella, and cover it with the lid. Do this while the soup is still hot, and you have just switched off the heat, so that the cheese will melt on top.
  • Serve with garlic bread, sourdough, or any other bread that you like.
    To store: refrigerate in a closed container for upto 3 days. Reheat in a saucepan or microwave with additional stock as the soup would have thickened. Add some fresh toppings

💡 Tips

  • For brothier soup, add an extra cup of water or broth when you add the tomato puree.
  • This dish is easiest to make in an oven-safe skillet, so you can just pop it right into the oven from the stovetop. If you don’t have one, you can ladle the soup into oven-safe bowls instead and bake or use the stovetop method.

Can I make it in the instant pot?

Yes. Cook the first 2 steps on saute mode. Once you add the stock, cancel saute. Add the broken lasagna sheets or pasta, mix well and close the lid. Pressure cook for 4-5 mins or about half the cooking time listed on the pasta box. Quick release in short bursts. Add in the tomato purée and cream and mix well and bring to boil on sauté. Taste and adjust flavor. Continue boiling if the pasta isn’t cooked to preference. Once done, remove the inner pot from the instant pot(as the bottom plate stays hot and will keep cooking the soup) . Ladle into bowls, top with crisped veggie ground and vegan cheese.

    Delicious! So comforting and satisfying. I made it with lentils. Next time I will try making it in a large cast iron and broiling the cheese on top. I was too hungry to wait this time 🙂 I like thick soup so I may add slightly less broth, but it does thicken a bit as it cools a little.

      Awesome!! Yes adjust the consistency as you like!
