- It’s quick and easy! This vegetarian lasagna soup is ready in about 30 minutes or less, and as you know, I love love love a dinner that comes together all in one pot! Not only is it simple to prepare, but it also makes cleanup that much easier too.
- It’s totally vegetarian but also SO filling! Creamy cheeses combined with pasta make this soup not only comforting but wonderfully filling. If you’re trying to introduce more meatless meals, this is one that will keep everyone full and happy.

Ingredients and Substitutions
- Onion & Garlic – I use white or yellow onion and fresh garlic. If you don’t have fresh garlic, you can substitute with ½ teaspoon of garlic powder or more to taste.
- Italian Seasoning – Italian seasoning is the typical herb blend used for Italian dishes and can be substituted with dried oregano, dried thyme, and dried sage.
- Tomato Paste – Tomato paste helps to deepen the flavor of the soup.
- Basil Pesto – There are so many delicious flavors in pesto and it’s just a fantastic addition to any dish – especially those with pasta! You can get your favorite pesto from the grocery store, or take a few minutes to make your own with my recipe (it’s so fresh!).
- Uncooked Red Lentils – Red lentils cook perfectly in this recipe. Brown or green lentils aren’t going to be able to cook through all the way before the pasta is done.
- Fire Roasted Crushed Tomatoes – Fire roasted are best because they add that delicious smoky flavor that just takes this dish to another level.
- Veggie Broth – Veggie broth keeps this soup meatless and doesn’t overpower any of the other flavors. You can use chicken broth instead if you’re not worried about keeping this vegetarian.
- Lasagna Noodles – Lasagna noodles are the obvious choice for this lasagna soup, but you can substitute with any short noodle you like.
- Parmesan Cheese – If you have a few extra minutes, grate your own Parmesan. Pre-grated cheeses contain preservatives designed to keep them from clumping together in their packages. Those same preservatives, however, mean the cheese doesn’t melt together as smoothly as you’ll want it to. For the best texture, get a wedge of Parmesan and grate it at home!
- Mozzarella Cheese – I prefer whole milk mozzarella for the best flavor and texture, but part-skin will work as well.
- Whole Milk Ricotta Cheese – As with most cheeses, I like to get the whole milk option. Part-skim will work but it won’t have as much flavor.
Instructions
Sauté onions in olive oil in a Dutch oven. Add garlic and dried herbs and cook for another minute.
Add tomato paste to the pot and stir to combine.
Cook for about 2 minutes or until the tomato paste turns brick red.
Deglaze the pot with a splash of veggie broth.
Add pesto and lentils.
Then add crushed tomatoes.
Add remaining veggie broth (and sugar, if using) and bring to a gentle simmer.
Stir in uncooked lasagna. And simmer for about 12-15 minutes or until the pasta is cooked al dente.
Stir occasionally while it’s simmering so that the noodles and lentils don’t stick to the bottom of the pan.
Remove from heat and add spinach.
Stir until spinach wilts. Season to taste with Kosher salt and black pepper.
Add Parmesan, ricotta, and mozzarella to the top of the soup.
Cover with the lid for a few minutes so the cheese melts. Or garnish each bowl individually with the cheeses and fresh chopped parsley.
Tips
- Can’t find crushed tomatoes? No problem. You can use tomato puree, canned tomato sauce, or jarred spaghetti sauce instead – the soup will just have a smoother consistency. Alternately, you can get a can of whole, peeled tomatoes and crush them yourself for a more chunky tomato texture in your soup!
- You can use whatever kind of pasta you have on hand for this creamy vegetarian lasagna soup. I like to use broken lasagna noodles, but bowties (or farfalle) penne, rotini, rigatoni, or even macaroni would work well in this recipe!
- Any sturdy green will work. You can easily swap out the spinach for another sturdy green like chopped kale. I sometimes like to use Swiss chard, mustard greens, or collard greens. I have even used arugula in a pinch, which added a little bit of a peppery flavor! Use whatever you’ve got in the fridge. And because it’s going to wilt anyway, you can use greens that are slightly past their prime!

Feel free to switch up this lasagna to include your favorite ingredients. Some of our favorite variations include:

FAQ
Lasagna soup has all the elements of traditional lasagna like lasagna noodles, mozzarella cheese, Parmesan cheese, Italian seasoning, and a tomato sauce base. Those ingredients are then combined with veggie broth, and other ingredients like lentils and pesto to make a hearty vegetarian soup.
Yes! Ricotta cheese is a soft cheese so it will get melty in warm soup which makes it perfect for this tasty lasagna soup!
Mini lasagna noodles are called Mafalda noodles and have rippled edges just like regular lasagna noodles. You can use mini lasagna noodles or break up the regular lasagna noodles into smaller pieces for this soup.
Storage and Reheating
- Storage: Store lasagna soup leftovers in airtight containers in the fridge for 2-3 days.
- Reheating: The best way to reheat this lasagna soup is in a pot on the stovetop over medium heat. You may need to add a bit of broth to loosen it up a bit. You can also pop it in the microwave for 30-60 seconds at a time until warmed through. Season to taste with salt and pepper before serving!

I have made this recipe a couple of times and love it! It is so flavorful and filling. I do have one question – would no-boil lasagna noodles work in this recipe? I happen to have some in my pantry from the last time I made lasagna and would prefer to use them up if I can. If they might become too mushy, I will purchase mafalda or lasagna noodles the next time I am at the grocery store. Thank you!
Good question! I haven’t tried it before but I imagine they might break down a bit too much to be enjoyable in this soup. You might be better of saving those noodles for a no-boil lasagna recipe!
Thanks so much for sharing this recipe! If you add sugar, at what point do you add it?
Great question, Sara! I just added that to the recipe card. I usually add it along with the vegetable broth before simmering. It’s nice to cut the acidity from the tomatoes with a little something sweet, but it’s not completely necessary. Hope that helps!
Is there a way to cook this in the crockpot that you’d recommend? 🙂
Thanks!
Hmmm this might be a tricky one to cook in the crock pot. You certainly could give it a try but I’m not sure what the cook times would be. I’d love to hear how it goes if you give it a try!
loved this recipe! thanks for a filling and delicious vegetarian one pot soup!!
Have you ever tried to freeze this soup to keep on hand later?
I have not! I’m not sure how the noodles would do freezing in the broth and then thawing. I fear that they may end up a bit mushy 🙁
Hello! Does the 2 cans (28 oz) mean 2 28oz cans or a total of 28 oz?
Hi Faith! It means 2 cans of tomatoes that are 28 oz. each 🙂 Hope that clears it up!
So delicious. I love how easy it was to throw this together after work. Thank you for such a yummy recipe!
What weight do you mean by 8 noodles?
Lasagna noodles vary in thickness and weight in various brands. Some 1 pound boxes I have bought contain 12 noodles, others have 16 noodles. The difference is the thickness, and slightly different length and width.One cooking website says 1 pound of lasagna is 10 noodles! I imagine some brands have a different count.
That’s true! But don’t overthink it, Phillip! Most packages of lasagna noodles are 16 oz. and are the same general shape and size, so 8 noodles will be about 8 ounces of pasta. This recipe is super forgiving though so if you add a bit less or a bit more it will still turn out delicious!
Hearty and tasty, which is always a concern I have with vegetarian recipes. I tasted it before adding the cheese and cream and liked it that way too, if you added beans ar that point you’d have a good minestrone.
I am so glad that you enjoyed this soup, Joe! I love a good minestrone too – might have to add my family recipe to the blog at some point 🙂 Thanks for leaving a review – I really appreciate it!
I gave this a try and it was outstanding! So good. Also, looking forward to tomorrow’s income report! My favorite posts 🙂
I am so glad that you enjoyed this recipe, Juliette! Thank you for leaving a review! My October income report will be posted in just a few minutes 🙂
