This hearty soup is simple to make!

For the Soup Base

• Canned Diced Tomatoes (28 oz) – Base ingredient for the soup’s flavor. Fresh tomatoes can be used if in season.
• Chopped Fresh Basil (⅓ cup) – Adds aromatic freshness. Dried basil can be used as a substitute but reduces flavor intensity.

• Canned Crushed Tomatoes (28 oz) – Thickens soup and enhances the tomato flavor. Can replace with tomato sauce if necessary.
• Nutritional Yeast (¼ cup) – Contributes a cheesy flavor and enriches the soup with B vitamins. Omit if unavailable.
• Dried Thyme (2 tsp), Onion Powder (2 tsp), Oregano (2 tsp) – Blend of herbs adds complexity to flavor. Fresh herbs could enhance flavor but adjust quantities.

For the Seasoning
• Black Pepper (¼ tsp), Salt (½ tsp, to taste) – Seasoning to enhance overall flavor. Use sea salt or reduce if mindful of sodium intake.

For the Liquid
• Vegetable Broth or Water (4 cups) – Liquid base for soup. Use low-sodium options or water for a lighter version.

For the Noodles
• High Protein Lasagna Sheets (6 sheets, broken into small pieces) – Main carbohydrate, adds heartiness. Substitute with gluten-free pasta.

For Creaminess
• Shredded Mozzarella Cheese or Vegan Mozzarella Shreds (¾ cup) – Adds creaminess and flavor. Omit for a lower-calorie version or choose a non-dairy cheese alternative.

Step‑by‑Step Instructions for High Protein Vegan Lasagna Soup

Step 1: Sauté the Mushrooms
Begin by cleaning and finely chopping the portabella mushrooms into small pieces. In a large pot, heat 2 tablespoons of extra virgin olive oil over medium-high heat. Add the chopped mushrooms and sauté for 8–10 minutes until they are tender and releasing their juices, stirring occasionally to prevent sticking.

Step 2: Add Aromatics and Tomatoes
Next, incorporate 28 ounces of canned diced tomatoes, ⅓ cup of chopped fresh basil, and 4 minced garlic cloves into the pot. Cook this mixture for 3–4 minutes, stirring often, until the garlic becomes fragrant and the tomatoes start to break down slightly, creating a robust base for your High Protein Vegan Lasagna Soup.

Step 3: Mix in Additional Ingredients
Stir in 28 ounces of canned crushed tomatoes along with ¼ cup of nutritional yeast, 2 teaspoons of dried thyme, 2 teaspoons of onion powder, 2 teaspoons of oregano, and ½ teaspoon of salt. Pour in 4 cups of vegetable broth or water, stirring well to combine all the flavors. Bring this mixture to a boil over high heat, letting the beautiful aromas fill your kitchen.

Step 4: Incorporate the Lasagna Noodles
Once boiling, break 6 high-protein lasagna sheets into small pieces and add them to the pot. Mix well to ensure the noodles are submerged in the broth. Reduce the heat to low, cover the pot, and let it simmer for 20 minutes, or until the noodles are tender and cooked through, stirring occasionally to prevent sticking.

Step 5: Serve and Add Cheese
After simmering, check the soup’s consistency; if you prefer a thicker texture, let it simmer uncovered for a few extra minutes. Scoop the piping hot High Protein Vegan Lasagna Soup into bowls, and for each serving, sprinkle about 2 tablespoons of shredded mozzarella cheese or vegan mozzarella shreds on top. Serve immediately, allowing the cheese to melt graciously into the warm soup.
