Ingredients and substitution notes 

  • Cherry Tomatoes: Cherry tomatoes are small and sweet, and add a pop of color to the soup. If you don’t have cherry tomatoes, you can use regular tomatoes, diced tomatoes from a can, or even sun-dried tomatoes for a more intense flavor.
  • Olive Oil: This is used to sauté the onion and garlic for added flavor. You can use any other cooking oil.
  • Onion: Adds a sweet and savory flavor to the soup. You can use any type of onion you have on hand.
  • Garlic: Adds a pungent and savory flavor to the soup. You can use garlic powder or minced garlic from a jar if you don’t have fresh garlic.
  • Italian seasoning: A blend of dried herbs that typically includes basil, oregano, and thyme. You can use any Italian herb blend you like or make your own by combining dried herbs.
  • Nutritional Yeast Flakes: Adds a cheesy and nutty flavor to the soup. If you don’t have nutritional yeast, you can skip it or add a tablespoon of miso paste instead.
  • Better-Than-Bouillon: A concentrated paste that adds flavor to the soup. You can use vegetable bouillon cubes or powder instead of Better-than-Bouillon.
  • Lemon Juice: Adds a tangy and bright flavor to the soup.
  • Salt: Balances the flavors in the soup. Use any type of salt you prefer.
  • Soaked Cashews: These add a creamy texture and nutty flavor to the soup. If you don’t have cashews, you can use soaked almonds or macadamia nuts instead.

Recipe variations and add-ins

Vegan lasagna soup is a hearty and comforting dish that’s perfect for colder days. Here are some recipe variations and add-ins to make your vegan lasagna soup even more delicious:

  • Vegetable Variations: Add in your favorite veggies to boost the nutrition of your soup. Try adding diced zucchini, mushrooms, or chopped spinach.
  • Protein Add-ins: Add in a protein source to make your soup more filling. You can add cooked lentils, chickpeas, or vegan meat crumbles.
  • Cheesy Add-ins: To make your soup even more flavorful, add in some vegan cheese shreds. You can use mozzarella, cheddar, or Parmesan-style cheese.
  • Creamy Add-ins: If you want a creamier soup, add in some vegan cream or coconut milk. This will give your soup a rich and decadent flavor.
  • Topping Options: Add some texture and crunch to your soup by adding toppings. You can use croutons or toasted nuts.

Top tips

  • Don’t skimp on the seasonings: Use plenty of seasonings to give your soup depth of flavor and make sure you taste the sauce and soup as you go so that it isn’t under-seasoned.
  • Be mindful of the soup’s thickness: Lasagna soup should be thick and hearty, but not too thick. If your soup is too thick, you can add a bit of vegetable broth to thin it out.
  • Use a large pot: Lasagna soup makes a lot of servings, so it’s important to use a large pot to avoid overflow.
  • Experiment with variations: Don’t be afraid to experiment with different vegetables, noodles, and spices to make your vegan lasagna soup unique and exciting every time you make it!
