Why You’ll Love this Vegetarian Lasagna Soup
This recipe combines all the hearty, cheesy comfort of lasagna in a weeknight-friendly soup.
As much as I love classic lasagna, I think we can all agree it’s a labor of love. Which is why this soup is the BEST possible alternative.
Not only does it come together in one pot, it’s on the table in under 40 minutes. Classic lasagna, on the other hand, can dirty a whole kitchen and take up to two hours. This recipe makes the weeknight lasagna experience totally feasible.
It calls for classic lasagna noodles, which get broken up into a jumble of shapes and sizes. Of course you could use any pasta noodle you like, but I love the varying texture lasagna sheets add.
And since I personally can’t imagine lasagna without ricotta cheese, the soup gets finished with an herb-y ricotta mixture.
You can swirl the cheese mixture into the soup, or just dip some crusty bread in it. Either way, it really rounds out the whole lasagna-in-a-bowl experience.
The Ingredients:
- Mushrooms: In place of beef, cremini mushrooms add meaty texture and savory depth to this vegetarian soup.
- Zucchini: The mild flavor of zucchini make it a fabulous contender for all lasagna recipes. Alternatively, you can use fresh baby spinach.
- Onion: Either yellow or white onion will work here.
- Garlic: Feel free to use as much (or as little) garlic as you like. I find that 3 to 4 cloves is just the right amount.
- Seasonings: To streamline the dry herbs, I prefer using a Italian seasoning mix. Alternatively, you can just add a few pinches of dried oregano.
- Tomato Paste: The key to unlocking the full flavor potential of tomato paste is to cook it for 2 to 3 minutes, until it’s deeply caramelized. (It should turn a brick-red color.)
- Crushed Tomatoes: Look for a can of crushed tomatoes with basil for extra flavor.
- White Beans: What makes this lasagna soup vegetarian is using white beans over meat. I prefer using a small white bean, such as navy beans, in this soup.
- Broth: Vegetable or chicken broth work great!
- Lasagna Sheets: Use classic, whole-wheat, or gluten free lasagna sheets. Use your hands to break the sheets into small pieces.
- Parmesan: Freshly grated Parmesan is added to both the soup and the ricotta mixture. I also like to grate some extra cheese over each bowl.
- Ricotta: I strongly suggest using full-fat ricotta cheese, as the soup does not have much fat in it. The ricotta topping adds richness, and really rounds out the lasagna experience.
Step-by-Step Instructions
Step 1: Sauté veggies, including onion, mushrooms, and zucchini in a large pot until soft.
Step 2: Add garlic, tomato paste, and seasonings; cook 2 to 3 more minutes, until aromatic.
Step 3: Add tomatoes, broth, and beans; bring soup to a boil. Add lasagna pieces, and reduce heat to a gentle simmer. Simmer until the noodles are al dente.
Step 4: Prepare ricotta mixture in a medium bowl; set aside until ready to serve.
Step 5: Stir in parsley and Parmesan, and ladle soup into bowls. Top with a dollop of the ricotta mixture and drizzle of olive oil.

Recipe FAQs
Let the soup completely cool before transferring it an airtight container. Store in the refrigerator for up to 4 days. (Store the ricotta mixture separately.)
1. Allow the soup to completely cool. Either stick it in the refrigerator, or place the whole pot in a bath of ice water in the sink. To better release the heat, stir the soup every so often while it’s chilling.
2. Ladle the soup into gallon- or quart-size zip-top plastic freezer bags, let out any trapped air, and tightly seal.
3. Lay bags flat in a single layer in the freezer. It’s important to not stack them until they’re frozen, or else they may stick.
In frozen, transfer bags of soup to the refrigerator and let thaw overnight. Once thawed, pour the soup into a Dutch oven or stock pot, and cook over medium heat until warm.

Nutrition
I calculate these values by hand to ensure accuracy, however expect up to a 10% variable depending on food brands.
It says 4 cups of broth.
Then says add 2 cups
Where do the other 2 cups go
It says to add BROTH and 2 cups of water.
This is such a good winter soup! Very easy and tasty. Sometimes we add veggie meat balls to it
Would this taste just as well without mushrooms? (Allergic)
And yet another winner! This was easy and delish. Used up some shallots in lieu of the onion and subbed Northern beans bc the grocery delivery service we use was out of navy beans … other than that, was by the book. Used low fat ricotta bc the non dairy was $8 – yikes! Don’t skip the cheese – it was so tasty!!! We may or may not have had some ciabatta (recommend). 🙂 Thanks for making such wonderful meals!!
Hi Jennifer – I’m so thrilled you enjoyed the soup! Thank you so much for taking the time to leave a review! Cheers.
I’m planning to make a vegan ricotta to top this; can I use a vegan parmesan cheese replacement in the soup or leave that out?
Yes, vegan Parm will work just fine!
Easy and delicious! Reheats well. I thought the noodles might be too soggy, but it was just lovely! Another great recipe Jamie!
This was brilliant! I used ½ red bell pepper, a bit of chopped carrot & 2 links veg (Tofurkey) Italian “sausage” instead of mushrooms, because what I had. So tasty & forgiving, I can see any reasonable sub working great. Thanks for a new fave 🙂
DELICIOUS!! I’m Italian and always looking for lighter, and simpler variations to our classics. I froze half, so excited to see how it holds up!
My family loved it! And it certainly does make good leftovers. Only adjustment I made was whole wheat lasagna noodles and doubled the beans.
Fantastic!! So glad you enjoyed it!
Absolutely delicious!! Enjoying the leftovers on repeat!
Leftovers are the BEST. So glad you’re enjoying it!
