Step‑by‑Step Instructions for Vegetarian Lasagna Soup
Step 1: Heat the Base
In a large pot, heat 2 tablespoons of olive oil over medium-high heat. Add the diced onion, stirring in a pinch of salt and pepper, and sauté for about 3 minutes until the onion becomes soft and translucent. You should see the onion turning a light golden color—this indicates it's ready for the next step.
Step 2: Add Aromatics
Lower the heat to medium and add 3 cloves of sliced garlic and 1 tablespoon of Italian seasoning. Stir continuously for about 1 minute, allowing the fragrant aroma of garlic and herbs to fill your kitchen. This important step enhances the depth of flavor in your Vegetarian Lasagna Soup.
Step 3: Incorporate Tomato Paste
Stir in 2 tablespoons of tomato paste and cook for about 2 minutes, allowing it to caramelize slightly. Keep an eye on the mixture as it turns a deep red color, releasing a rich sweetness and pasty texture, which helps to intensify the soup's flavor profile.
Step 4: Deglaze with Broth
Carefully pour in 6 cups of vegetable broth, scraping the bottom of the pot with a wooden spoon to deglaze and lift all the flavorful bits stuck to the bottom. Bring the mixture to a gentle boil, which usually takes about 2-3 minutes, while ensuring everything is well combined.
Step 5: Simmer the Soup
Add 1 cup of basil pesto, 1 cup of red lentils, 1 can (28 ounces) of fire-roasted tomatoes, and the remaining vegetable broth. Optional: add a teaspoon of sugar, salt, and pepper to taste. Bring the soup to a simmer over low heat, allowing it to bubble gently for about 10 minutes.
Step 6: Cook the Noodles
Next, stir in 4 broken lasagna noodles and reduce the heat. Simmer uncovered for 12-15 minutes, stirring occasionally. The noodles should become tender and swell, soaking up all the lovely flavors of the Vegetarian Lasagna Soup while preventing the lentils from sticking to the bottom.
Step 7: Add the Spinach
Once the noodles are cooked, turn off the heat and gently stir in 2 cups of fresh baby spinach until just wilted, which should take about 1 minute. Make sure the spinach brightens the soup, adding a splash of color and nutrients to this hearty dish.
Step 8: Garnish and Serve
Ladle the Vegetarian Lasagna Soup into bowls and top each serving with Parmesan, mozzarella, and ricotta cheese to enhance its creaminess. Finish with a sprinkle of fresh parsley for added brightness and flavor, and enjoy this delightful soup warm!
How to Store and Freeze Vegetarian Lasagna Soup
Fridge: Store leftovers in an airtight container for up to 3 days, ensuring the soup remains fresh and flavorful.
Freezer: It is not advisable to freeze the soup with spinach and cheese. Instead, freeze the base without these ingredients for up to 2 months and add fresh spinach and cheese upon reheating.
Reheating: When reheating, add a splash of vegetable broth to restore liquid as the noodles absorb moisture over time, keeping your Vegetarian Lasagna Soup rich and delicious.
Make-Ahead: Prepare the soup base a day in advance for deeper flavor; just remember to add spinach and cheeses right before serving for optimal texture.
Vegetarian Lasagna Soup Variations

- Cheese Adventure: Experiment with different cheese combinations, using sharp cheddar or pepper jack for a twist on flavors. Alternatively, go for vegan cheeses for a plant-based delight without sacrificing creaminess.
- Gluten-Free Noodles: Opt for gluten-free pasta to make your soup suitable for gluten-sensitive friends. There are several great options available that will still absorb the flavors beautifully.
- Herb Infusion: Add a sprig of fresh thyme or rosemary during simmering for an aromatic boost. The fragrant herbs will infuse your soup with warmth and depth that makes every spoonful even more delightful.
