Vegetarian Lasagna Soup is a one-pot, comforting, hearty meal full of veggies and lasagna noodles in an Italian flavored tomato broth. Serve it topped with a three-cheese mix for that cheesy creamy deliciousness!!
We love lasagna but honestly its a bit of effort to make and assemble. So here is a deconstructed and much easier version of it, the Vegetarian Lasagna Soup with the same flavors and delicious taste.
I love making it in my favorite kitchen gadget, Instant Pot as it such a breeze but you can also make it on the stovetop, crockpot, or slow cooker.
What is Lasagna
Lasagna is an Italian pasta dish made of several alternating layers of a thin flat pasta noodle (also known as lasagna sheets or lasagna noodles), pasta sauce (tomato sauce, or marinara) with veggies or meat, and cheese mixture (ricotta, parmesan).
The final layer is topped with mozzarella and baked until cheese has melted and is golden.

Let's see how to make Instant Pot Vegetarian Lasagna Soup recipe.
Recipe Ingredients
- Lasagna noodles - I use regular lasagna noodles but you can replace them with pasta of choice.
- Aromatics - yellow onion and minced garlic
- Veggies - Fresh veggies like Carrots, zucchini, red bell pepper, broccoli and spinach, canned diced tomatoes, and tomato sauce.
- Herbs and Seasoning - Italian seasoning, dry oregano, red pepper flakes, salt, and freshly cracked black pepper and fresh basil leaves.
- Cheese mixture - I prefer using a combination of Ricotta cheese, mozzarella, and parmesan cheese.
- Olive Oil: use a good quality olive oil for cooking this soup.
- Veg Broth: I prefer using water mixed with better than bouillon vegetable base to create my broth. But you can use your favorite one or gluten-free option.
Instant Pot Step by Step Instructions
1 - Start the Instant Pot on saute mode (normal) and add olive oil. Once the oil is hot, add the onions, carrots, bell pepper, and garlic. Mix and cook for about 1-2 mins or until the onions turn translucent.
2 and 3 - Add in the rest of the ingredients like zucchini, diced tomatoes, tomato sauce, spices (salt, oregano, Italian seasoning, freshly cracked black pepper, red pepper flakes), and broken lasagna noodles.
4 - Add 4 cups veg broth. Mix well. Ensure most of the noodles are below the liquid.
5- Close the lid and cover and cook on manual (pressure cook) high for 5 mins followed by a quick release.
6- Open the lid and add the broccoli florets and spinach. Mix to combine and cover and let it sit for 10-15 mins. The broccoli and spinach will cook in the steam.
7 - In the meanwhile make the cheese topping. Add and mix all the cheeses Ricotta, mozzarella, and parmesan. Keep refrigerated until ready to serve.
8 - Open Instant Pot after 15-20 mins and delicious easy vegetable Lasagna soup is ready! Serve immediately.

Serving suggestions
Serve this easy vegetarian lasagna soup warm topped with three cheese topping and freshly cracked pepper, salt flakes, and a sprinkle of red pepper flakes (optional).
The soup is good on its own and a complete meal but to make it more filling serve it with a side of salad or sandwich or cheesy garlic bread.
Variations
To make this soup, even more, heartier and for that added protein boost, add some rinsed and soaked red lentils (split and skinned lentils) or some tofu pieces to keep it vegetarian/vegan or some ground chicken.
For all these options, the cooking time will remain same.
Recipe Tips and Notes
- No boil, as well as regular noodles, work for this recipe. Or replace it with your favorite pasta shape.
- Break the noodles in bite-size pieces and mix them well so they don't stick to each other. Also, make sure they are under liquid so they cook evenly.
- Lasagna noodles (like pasta) have a tendency to soak up all the liquid so serve immediately.
- If planning to serve later, cook the noodles separately, and add to the soup just before serving and give it a boil so the flavors soak up.
- To prevent burn errors, make sure to deglaze the pot and mix everything well before closing the lid.
- You can swap tomato sauce with your favorite marinara sauce.
- This recipe can be doubled, cooking time remains the same.
Frequently asked questions
Yes, but freeze the soup without the pasta and cheese mixed in. Pasta will absorb all the liquid so freeze it separately. Similar for cheese. To serve thaw both overnight in the fridge and then warm and serve.
Yes, the soup is vegan, so just replace the three-cheese mixture with vegan cheeses. Use gluten-free noodles to make it gluten-free but the cooking time may vary.
