Vegan Lasagna Soup Recipe (Gluten Free & Oil-Free)

One of my favorite cold weather comfort meal is vegan lasagna soup!

Lasagna is time-consuming to make from scratch, so I don’t make it very often. But that all changes with this vegan lasagna soup recipe. 

This soup packs all the delicious and comforting flavors of a regular vegan lasagna, but without all the mess in the kitchen. Instead of a few hours of preparation, this soup only takes about 30 minutes. 

It is super easy to make, and you can customize it any way you want by adding extra veggies or kicking up the spice.

Why You’ll Love Vegan Lasagna Soup Recipe

  • It is super easy to make. You can get all of the lasagna flavors without all of the preparation. Plus, it is one pan, which makes for an easy clean-up. 
  • It has a variety of vegetables like bell peppers, tomatoes, and onions. 
  • Mushrooms are a great source of antioxidants, protein, and fiber. 
  • Lentils are an excellent source of protein and iron. 
  • It is gluten-free and oil-free, so you can easily accommodate all diets. 

How To Make This Tasty Lasagna Soup

In your dutch oven or a large pot, start heating your garlic with 1-2 tablespoons of water. Once that starts cooking, add in all of your vegetables including the cherry tomatoes. 

Let the vegetables soften for about 5 to 7 minutes, and then add in your lentils, water, and tomato sauce. If your tomato sauce does not have any seasonings in it, add in some Italian seasonings too. 

Mix everything together and bring it to a boil. Once it is boiling, break-up your lasagna noodles and add them to the soup. 

Cover the soup and let it simmer for about 15 to 20 minutes, or until the lasagna noodles and lentils are fully cooked. 

Once they are cooked, add in your spinach and let it wilt, mixing the soup well. Serve this soup with basil, red pepper flakes, and/or nutritional yeast on top.
