Essential Ingredients for Your Lasagna Soup

The beauty of this vegetarian lasagna soup lies in its straightforward yet flavorful ingredient list. Here’s a closer look at the key components:

• Beans: These are the true protein powerhouses of this soup, providing essential fiber and making the dish incredibly filling and comforting. The choice of beans is flexible – feel free to use what’s available in your pantry. I’ve personally used a combination of kidney beans and carlin peas (which are similar to chickpeas), but butter beans, white beans, black beans, or even lentils would all work wonderfully. For superior flavor and texture, I highly recommend using jarred beans whenever possible, as they often have a more tender bite than their canned counterparts.
• Mushrooms: Regular white button mushrooms are perfectly fine for this recipe, offering a mild, earthy note. However, if you’re looking to elevate the umami depth, consider using porcini mushrooms. Dried porcini mushrooms, in particular, bring an intensely rich, savory flavor that transforms the soup. If dried porcini aren’t accessible, you can omit them and simply increase the vegetable stock for the liquid component.
• Canned Tomatoes: The foundation of our rich, tomato-based broth comes from canned tomatoes. You can opt for whole plum tomatoes, crushed tomatoes, or passata (often labeled as tomato puree in the US). Each offers a slightly different texture but contributes to the essential tangy sweetness of the soup.
• Vegetable Stock: This liquid base adds significant depth of flavor. If you’re strictly keeping the soup vegetarian or vegan, ensure your stock is vegetable-based. For non-vegetarians, chicken or beef stock can be used for a different flavor profile. In a pinch, water can be substituted, but remember to adjust the seasoning with more salt to compensate for the reduced savory notes.
• Fish Sauce (Optional): While it might seem like an unusual addition for a vegetarian dish, a touch of fish sauce can dramatically boost the savory, umami dimension of the soup without imparting a “fishy” taste. It functions much like a hidden flavor enhancer. If you’re strictly vegetarian or vegan, or simply prefer not to use it, you can easily skip it or seek out a vegetarian fish sauce alternative, which is often made with mushrooms or seaweed.
• Aromatics & Herbs: Onions, carrots, celery, and garlic form the foundational flavor base, while dried oregano and fresh basil infuse the soup with classic Italian aromas.
• Lasagna Sheets: These are the star of the show, broken into pieces and cooked directly in the soup, absorbing all the delicious flavors.
• Ricotta & Parmesan: A dollop of creamy ricotta, mixed with parmesan and fresh basil, provides a luxurious, cooling counterpoint to the hot, savory soup, beautifully mimicking the béchamel layer found in traditional lasagna.

Step-by-Step Guide: Crafting Your One-Pot Lasagna Soup

Making this hearty homemade lasagna soup is incredibly straightforward and designed for efficiency. Follow these simple steps to bring this comforting dish to life:

1. Prepare Your Veggies & Mushrooms: Begin by finely dicing your onion, celery, carrot, and mushrooms. Precision here is key to ensuring the “hidden veggie” aspect works its magic. Mince your garlic cloves. If using dried porcini mushrooms, place them in a small heatproof bowl, cover with 1 cup of hot water, and set aside to rehydrate. For efficiency, consider using a food processor or chopper to achieve a very fine dice, though hand-chopping is perfectly fine.
2. Sauté the Aromatics: Heat two tablespoons of olive oil in a large, heavy-bottomed pot or Dutch oven over medium-high heat. Add the diced onion, carrot, celery, fresh mushrooms, minced garlic, and salt. Cook, stirring frequently, until the vegetables begin to soften and become fragrant, which typically takes about 5 minutes. Stir in the tomato paste and cook for another couple of minutes, allowing it to deepen in color and flavor.
3. Build the Soup Base: Remove the rehydrated dried mushrooms from their soaking liquid, gently squeezing out any excess water, then chop them roughly. Keep the soaking liquid – it’s packed with flavor! Add the chopped rehydrated mushrooms, their soaking liquid (strained to remove any grit), the drained beans, canned tomatoes, vegetable stock, dried oregano, and fish sauce (if using) to the pot. Using the back of your spatula or spoon, roughly mash some of the beans against the side of the pot. This step is crucial for thickening the soup and creating a richer, more textural consistency. Stir everything together, bring the mixture to a gentle simmer, then reduce the heat to low, cover, and let it simmer for about 15 minutes. This allows the flavors to meld beautifully and the soup to thicken slightly.
4. Prepare the Ricotta Topping: While the soup simmers, prepare your creamy topping. In a small bowl, combine the ricotta, grated parmesan cheese, a pinch of salt, a generous grind of black pepper, and a handful of freshly chopped basil leaves. Mix until well combined and set aside.









5. Add the Lasagna Sheets: Once the soup has simmered for 15 minutes and slightly thickened, it’s time for the pasta. Break the dried lasagna sheets into bite-sized chunks (roughly 1-2 inch pieces). Add them directly to the simmering soup. Stir them through gently to ensure they are fully submerged and don’t stick together. Continue to cook for about 10 minutes, stirring occasionally, until the pasta is al dente – cooked through but still with a slight bite. Avoid overcooking to prevent mushy pasta.
6. Finish and Serve: Stir in another handful of freshly chopped basil and the remaining grated parmesan cheese into the soup. Add a final generous grind of black pepper, then taste and adjust seasoning with a little more salt if necessary. Ladle the hot, gorgeous lasagna soup into bowls and top each serving with a generous dollop of the herby ricotta-parmesan mixture. Serve immediately and enjoy your homemade masterpiece!

• A handful of fresh basil leaves, chopped (divided)

Instructions

1. Prepare your veggies: If using, add dried porcini mushrooms to a small bowl, cover with 1 cup hot water, and set aside. Finely dice onion, carrot, celery, and fresh mushrooms; mince garlic.
2. Cook the veggies: Heat 2 tablespoons olive oil in a large pot over medium-high heat. Add diced onion, carrot, celery, fresh mushrooms, garlic, and 2 teaspoons salt. Cook, stirring, until softened (about 5 minutes). Stir in 2 tablespoons tomato paste for 2 more minutes.
3. Add the beans, tomatoes, and stock: Remove rehydrated porcini from water, chop roughly (strain and reserve soaking liquid). Add chopped porcini, strained soaking liquid, drained beans, canned tomatoes, 3 cups stock, 1 tablespoon dried oregano, and fish sauce (if using) to the pot.

5. Add the lasagna sheets: After simmering for 15 minutes, break lasagna sheets into chunks and add to the soup. Stir them through and cook for about 10 minutes until al dente (cooked but with a slight bite). Stir occasionally to prevent sticking.
6. Finish and serve: Stir in the remaining chopped basil and parmesan cheese. Add a good grind of black pepper, taste, and season with more salt if needed. Ladle soup into bowls and top with a dollop of the herby ricotta mixture. Serve hot.

Notes

STORAGE INSTRUCTIONS: This is excellent for meal prep. The soup keeps well for up to five days in the fridge. Pasta will soften further, but it will still taste great. Reheat on the stovetop or in the microwave. Can be frozen for up to 3 months.

PREP AHEAD: Make the soup base (up to adding lasagna sheets) up to 5 days in advance. Reheat the base, then add pasta and finish the recipe when ready to serve.

INGREDIENT NOTES: This recipe is highly adaptable. Use any finely chopped vegetables you like (zucchini, fennel, leeks, cauliflower, broccoli, soft tomatoes). Any beans or pulses (black, kidney, butter, white beans, chickpeas, lentils) work well.
