How to Make Vegetarian Lasagna Soup
Sauté the Vegetables
In a large pot, heat olive oil over medium heat. Add chopped onions, carrots, and bell peppers. Sauté for 3–4 minutes until softened. Add garlic, mushrooms, and zucchini, cooking for another 3–4 minutes until the mushrooms release their moisture.
Build the Broth
Stir in the tomato paste and let it cook for a minute to deepen its flavor. Add crushed tomatoes, vegetable broth, Italian seasoning, basil, oregano, salt, and red pepper flakes. Bring to a simmer and let it cook for 10–15 minutes so the flavors can blend together.
Add the Pasta
Break the lasagna noodles into bite-sized pieces and mix them into the soup. Let them simmer in the broth for about 10 minutes until tender. Stir occasionally to prevent sticking.
Prepare the Cheese Topping
While the soup simmers, mix ricotta, parmesan, and mozzarella cheese in a small bowl. This will be your “lasagna-style” topping.
Serve and Enjoy!
Once the noodles are cooked, taste the soup and adjust the seasoning if needed. Ladle the soup into bowls, top each serving with a spoonful of the ricotta mixture, and sprinkle with fresh basil. Enjoy while hot!

Tips for the Best Vegetarian Lasagna Soup
Making vegetarian lasagna soup is simple, but a few pro tips will help you get the best flavor and texture every time.
🔥 Use High-Quality Tomatoes – Since tomatoes are the heart of the soup, opting for good-quality canned tomatoes adds richer flavor and better texture. Look for San Marzano or organic crushed tomatoes for a richer, more balanced flavor. If your tomatoes taste a bit acidic, add a pinch of sugar to mellow them out.
🥕 Don’t Overcook the Pasta – Nobody likes mushy noodles! To keep the pasta just right, cook it until al dente. If you’re meal prepping or freezing the soup, cook the noodles separately and add them when serving. This way, they won’t soak up too much broth and get mushy.
🌱 Boost the Protein – Want to make this soup even more filling? Stir in cooked lentils, chickpeas, or plant-based ground meat to boost protein and make the dish more filling.
This makes it a more satisfying meal, especially if you’re serving it as a main course.
🧀 Customize the Cheese Topping – If you’re a cheese lover, don’t stop at ricotta! Sprinkle in shredded mozzarella or parmesan just before serving for an extra gooey, cheesy bite. Want a dairy-free option? Use vegan ricotta or cashew-based cheese for the same creamy texture.
With these tips, your vegetarian lasagna soup will be flavorful, hearty, and absolutely delicious every time!

What to Serve with Vegetarian Lasagna Soup
While vegetarian lasagna soup is hearty and satisfying on its own, pairing it with the right side dishes can elevate the meal and create a complete dining experience. Here are some delicious sides that complement the flavors of this cozy soup:
🥖 Garlic Bread – There’s nothing better than warm, crispy garlic bread to soak up the rich tomato broth. You can make it with a classic garlic butter spread or add a sprinkle of parmesan and fresh herbs for extra flavor.
🥗 Simple Green Salad – A light and refreshing salad balances the heartiness of the soup. Try a mix of arugula, spinach, or romaine with a tangy vinaigrette. A Caesar salad or a Mediterranean-style salad with olives and feta also pairs beautifully.
🧄 Roasted Vegetables – If you want to add more veggies to your meal, serve this soup with roasted zucchini, bell peppers, eggplant, or asparagus. The caramelized flavors of roasted vegetables enhance the depth of the soup while adding extra nutrition.
🍷 Wine Pairing – If you enjoy wine with dinner, a medium-bodied red wine like Chianti or a Sangiovese pairs well with the tomato-based broth.
No matter how you serve it, this soup is a comforting, crowd-pleasing meal that everyone will love!

How to Store and Reheat Leftovers
This soup stores well and, like most pasta-based dishes, tastes even better the next day as the flavors continue to meld. Here’s how to keep it fresh and delicious:
Refrigerate:
Store leftover lasagna soup in an airtight container in the fridge for up to 4 days. The flavors will deepen over time, making it even tastier! However, the pasta will continue to absorb liquid, so you may need to add extra broth when reheating.
Freeze:
If you want to freeze the soup, let it cool completely before transferring it to freezer-safe containers. Freeze in individual portions for easy reheating. It will stay good for up to 3 months.
Reheat:
To reheat, warm the soup on the stove over low heat, stirring occasionally. If the pasta has absorbed too much liquid, add a splash of vegetable broth or water to loosen it up. If reheating from frozen, thaw overnight in the fridge before reheating.
Pro Tip: If you plan to freeze this soup, cook the pasta separately and add it fresh when reheating. This prevents the noodles from becoming overly soft and mushy. Doing this will keep your soup tasting just as good as when you first made it! 🍲
