In a large bowl or pyrex, whisk miso paste, Worcestershire sauce and tomato paste into 5 cups warm vegan beef broth until fully incorporated. This helps ensure the flavors are fully mixed into soup and there are no clumps.
Add all ingredients except for lasagna sheets and tofu ricotta to slow cooker pot.
Set slow cooker to 4 hours on high or 8 hours on low.
When lasagna soup has 20-25 minutes left to cook, break lasagna sheets into smaller pieces and stir into soup. Simmer noodles until al dente, about 20-30 minutes.
Serve immediately with a dollop of tofu ricotta, vegan mozzarella cheese shreds, nutritional yeast, red chili flakes, and fresh basil, if desired.
Instant Pot Instructions
In a large bowl or pyrex, whisk the miso paste, Worcestershire sauce and tomato paste into 4 cups warm vegan beef broth until fully incorporated. This helps ensure the flavors are fully mixed into soup and there are no clumps.
In the following order, add the ingredients to the Instant Pot: Vegan beef broth mixture, mushrooms, red lentils, spices, and crushed tomatoes. Do not mix.
Break lasagna sheets into thirds and layer on top of crushed tomatoes. Press them in slightly until just submerged. Again, do not mix.
Add the lid, and cook on manual high pressure for 6 minutes. Make sure the valve is set to seal.
Once Instant Pot has cooked at high pressure for 6 minutes, manually release pot pressure.
Serve immediately with a dollop of tofu ricotta, nutritional yeast, red chili flakes, and fresh basil, if desired.
Once soup has cooled to room temperature, transfer to storage containers and store in refrigerator for 3-5 days.
Remove the soup from slow cooker or Instant Pot immediately after cooking to prevent lasagna from overcooking.
If cooking in the Instant Pot, be sure to add the ingredients in the specific order listed. This is to prevent the lasagna, lentils and tomatoes from burning to the bottom of the pot.
I prefer making this soup in the slow cooker on low as it really allows the marinara to develop best flavor.
