Step-by-Step Instructions for Perfect Lasagna Soup

Follow these clear, detailed steps to create a restaurant-worthy soup at home:

1. Sauté the Aromatics: Heat olive oil in a large pot over medium heat. Add the diced onion and cook for 3–4 minutes until translucent. Stir in the minced garlic and cook for 30 seconds until fragrant.
2. Brown the Plant-Based Beef: Add the lean plant-based ground “beef” to the pot. Cook for 5–6 minutes, stirring occasionally, until lightly browned and the liquid has evaporated.
3. Build the Broth Base: Pour in the fire-roasted diced tomatoes (with juices) and vegetable broth. Stir well to combine, scraping up any browned bits from the bottom of the pot.
4. Add the Lentils and Seasonings: Stir in the rinsed red lentils, dried oregano, dried basil, and smoked paprika (if using). Bring the soup to a gentle boil, then reduce heat to a simmer.
5. Cook the Noodles: Add the broken lasagna noodles to the pot. Simmer for 12–15 minutes, stirring occasionally, until the noodles are al dente and the lentils are tender.
6. Finish with Greens and Brightness: Stir in the chopped spinach or kale and cook for 2–3 minutes until wilted. Remove from heat and stir in the nutritional yeast, lemon juice, salt, and black pepper.
7. Serve and Enjoy: Ladle the soup into bowls and top with a dollop of vegan ricotta, fresh basil, and grated vegan Parmesan. Serve immediately while hot.

Tips & Tricks for the Best Lasagna Soup

Make this soup even better with these expert tips:

• Boost the Protein Further: Stir in ½ cup cooked quinoa or white beans at the end for extra fiber and plant-based protein.
• Prevent Mushy Noodles: Break the noodles into small, even pieces before adding them to the pot. They’ll cook evenly without turning to mush.
• Make It Creamier: For a richer texture, blend ½ cup of the cooked soup (without noodles) and stir it back in at the end.
• Adjust the Consistency: Prefer a thicker soup? Simmer uncovered for 5 more minutes. Want it brothier? Add an extra ½ cup of vegetable broth.

How to Store and Freeze Lasagna Soup

This soup keeps well for quick meals later—here’s how to store it properly:
