This crockpot lasagna soup is like a deconstructed lasagna made in an Italian tomato broth full of vegetables with a creamy dollop of a three cheeses mixed in.

If you’ve found yourself trolling Pinterest, there’s a pretty good chance you’ve seen the meaty stove-top version of this easy vegetarian lasagna soup floating around. And there’s a perfectly good reason for that.
Because it’s so dang good!
I’m very much into giving my favorite comfort foods a different spin to make them brand new again. And when it comes to lasagna, I have a couple of recipe twists on this classic Italian comfort food up my sleeve, or at least, in my recipe box.
This time around, a healthy change-up to everyone else’s lasagna soup was in the works. To make the soup even simpler to make while coordinating the fam’s busy schedules, I took this vegetarian lasagna soup from the stove to the crockpot for cooking with ease.
Slow cooking makes lasagna soup easy to make any night of the week, and it can be made with the slow cooker function on the Instant Pot too.
Crockpot Lasagna Soup Ingredients
A few years ago I stumbled across my friend Brenda’s meaty version on Pinterest, and it’s what inspired me to give lasagna soup a whirl.
The flavors of lasagna soup are very similar to regular lasagna, just in a more slurpable form. The soup starts with some of my favorite Italian products from DeLallo, one of my long-time, most favorite partners here on the blog.
San Marzano-style tomatoes are a favorite of Italian cooks everywhere. DeLallo’s San Marzano crushed tomatoes are sun-ripened Italian plum tomatoes harvested in the Naples region of Italy. Their flavor is vibrant and sweet with a tender, meaty texture that’s been crushed smooth but thick, perfect for pasta sauces, and of course, soup.
To add a bit of bold body to the soup, I add DeLallo’s tomato paste, and all-natural double concentrate that’s extra rich and super thick in a squeeze tube so you can use a little or a lot without waste.
And of course, there’s the DeLallo lasagna noodles. Made with Italian semolina flour, these noodles cook perfectly every time, with the ridged edges capturing every bit of the soup’s broth.
Most of the crockpot lasagna soup recipes I’ve seen are made with sausage or ground beef to replicate the classic Italian recipe. But because I’m trying to add more meatless meals to our dinner table, I took this vegetarian crockpot recipe down the vegetable-only path, and used:
Mixed with the oregano and basil flavored tomato based broth, the lasagna flavors really shine through.
But where this soup really gets its lasagna-esque flavors is thanks to the mix of three cheeses that melt creamily into the soup for that true-blue lasagna flavor:
- creamy ricotta
- shredded mozzarella cheese
- grated Parmesan cheese
- fresh parsley and basil

How to Make Crockpot Lasagna Soup
Using a crockpot or the slow cooking function on the Instant Pot makes this lasagna soup recipe super easy to pull together the night before or in the morning and let it cook on low for 7-8 hours, or 3 ½ to 4 hours on high.
Sauté the onions, mushrooms, and garlic in a skillet before adding them to the slow cooker. If I’m really short on time I’ve skipped that step without noticing too much of a difference in flavor.
Then, add in the remaining ingredients (minus the lasagna noodles), turn on the slow cooker, and walk away. Once finished cooking, stir cooked lasagna noodles into the soup and throw in a few handfuls of spinach to wilt down.
Stir part of the ricotta cheese mixture into the soup just before serving it, then dollop a little more onto each serving.

Can I Make This Recipe Without a Slow Cooker?
I’m sure you can. You’d likely want to let the soup simmer over low heat for a few hours, then stir in the cooked lasagna noodles as instructed. The downside to making lasagna soup on the stove is that you can’t leave the house while the soup is cooking.
Can I Add Other Veggies to Crockpot Lasagna Soup?
I don’t see why not! Kale could easily be used instead of the spinach, you could add in some frozen peas in addition to the zucchini, and so forth. Let me know what vegetable combinations you try!

Tips for Making Crockpot Lasagna Soup
Avoid cooking the noodles in the crockpot with the sauce from the beginning of the cooking time. It will make the noodles absorb too much of the tomato sauce and become gummy. Instead, cook the lasagna noodles separately (undercook them slightly) and add the to the crockpot at the end of the cooking time to flavor.
A few readers have also suggested using cheese tortellini instead of the lasagna noodles and ricotta mixture. If you go the tortellini route, I still recommend cooking it separately and stirring it into the soup just before serving to avoid soggy pasta.
If you’re a meat lover, feel free to cook sliced chicken sausage separately, then add to individual bowls for a healthier lasagna bite.

I’ve made this half a dozen times or more now and we love it!! My kids love it even though they are not vegan like we are. Thank you for this recipe! ❤️
Ashley @ Foodie Crush
I am glad it is a hit for your whole family!
I’ve made this soup before and it is so delicious! However I am just wondering what a serving size is? The recipe says it makes 10 servings. Thank you!
Absolutely delish! Only change was more red pepper and fresh basil (no dried at home). The first thing my 9 year old said was “this is my new favorite food!” Definitely a keeper!
Love this recipe! My 16 year old vegetarian (who doesn’t really like veggies ;) and 8 year old loved it! The youngest had to draw what peace looks like in her class and said it was eating her mom’s homemade tomato soup (not really tomato soup, but high praise from someone who would eat pasta every day if I let her!.
I followed this recipe exactly (except I added 500g of Quorn vegetarian “beef mince”) and it turned out phenomenal! The dollop of ricotta is a great touch and is the ultimate healthy comfort food :) Thanks for sharing!
Caitlin, I’m so glad you made it your own. The veggie mince is a great touch!
I made this recipe today and it was SO good! I was looking for more vegetarian slow-cooker meals and this is perfect. I ended up using three cheese tortellini instead of lasagna noodles and the cheese topping, and it was still delicious. So if, like me, you are planning to make this as a meal prep and worry about keeping up with the ricotta topping, tortellini works! Thanks for the recipe!!
Thank you for letting us know Maria, love the idea of using tortellini.
I was going to ask if you could substitute cheese tortellini for the noodles and cheese because I plan to make this for Christmas eve dinner and I don’t want to have to fuss when the guests arrive. And here I see you tried it! Question? When did you add the tortellini and did you use frozen or fresh? Trying to make sure I don’t end up with super soggy tortellini. THANKS!
i just made your Slow Cooker Vegetarian Lasagna Soup today … i’m pretty much strictly a meat lover since birth – born and raised on a ranch …but i have to tell you this was excellent and very filling ! … i recently found your site – saw this recipe and it looked so good i had to try it … sure glad i did … i made exactly to your recipe except for accidentally putting all of the basil in the soup to cook instead of the 1/4 cup fresh basil in the ricotta topping mix … (groans) … but it turned out fine anyway in spite of my best attempt to do otherwise – which i seem to do from time to time as i meander thru one recipe or another … as my name says i’m just a guy who enjoys cooking for my wife and i and whoever else happens to be around … i’m the main cook here at home … we’re california transplants from colorado … thankfully soon to move back to colorado … i love your site … i’m looking forward to trying other recipes from you …you wanna know how good i thought this recipe was ? … this is the first comment i’ve ever made on something i tried .to cook from someone else’s recipe . .thank you for sharing … talk to you again soon
btw … we’re NASCAR fans as well … i’ve yet to make vegas but i will … i probably shouldn’t tell you who my driver is … but what the heck i can take the heat … Mr.. Harvick of course !!! … lol
This was absolutely delicious and I’d definitely make it again. It was the first recipe we tried in our slow cooker. We’d probably leave out the cream cheese next time but otherwise make exactly as it is. Thanks for the great recipe.
I made this today. So yummy. Will be making it again. Thanks for the great recipe. Always looking for good vegetarian recipes. Sending some back to college with my daughter
Thank you so much for submitting this yummy recipe. I made it today and had it for my dinner. Each spoonful was a delious and satisfying pause to savor. I absolutely loved the combination of flovors. The best part is there is lots leftover so my freezer is going to be well stocked.
I added browned chicken breasts and fresh garden okra…yummm.
Do you know if this recipe would do well if prepared and then put in freezer?
How many does it serve and how long did it take to prep?
Best. Mom. Ever! Now, if only I can convince my mom to bring me a bowl of this soup to work. I love that it’s meatless.
There are two adults and one 11month old in my family , and this makes so much ( which is awesome !) so I use fusili pasta and I make it separately and add it as needed.
This soup is so yummy,yummy,yummy !
I made this for supper this evening. It turned out perfectly, but I forgot the spinach. It still tasted wonderful, but I will valiantly attempt to remember the spinach next time. Just a thought or two. I added the lasagna noodles an hour before it was to be done and it turned out great. No need to dirty another pot if you are available to do that. Also, I am not a vegetarian, but gave up meat for all of Lent, so I searched for veggie recipes and came up with this. That being said, I think this would taste amazing with all of the veggies and Italian sausage. I also think bowtie pasta would be a wonderful substitute for the lasagna. Either way it was delicious! Thanks for the recipe.
I pinned this recipe, and then made it for dinner last night. Total winner! Super yummy, crock pot easy…thanks for such a fantastic recipe!
Oh wow. I have GOT to make this happen at my house soon! This looks fantastic!
Your soup sounds amazing! Slow cooker recipes are a must try for me!
Paula – bell’alimento

So awesome sounding, Heidi!
I am not a vegetarian but this still looks delicious! Running out to buy the ingredients this afternoon! :-)
I feel like I could reach in a take a bite of your soup photo. I like that you used the slow cooker, it looks delicious and satisfying on a cold winter day. Have fun skiing!

Brenda @ a farmgirl's dabbles
Excellent! My “meaty version” of lasagna soup is definitely a family favorite. And I think most of our friends and family can say that, too! Awesome to see your version (LOVE all the veggies!)…I’ve been working on a slow cooker rendition of this soup myself this winter! ;)
Slurp-able lasagna great! Nothing like warm bowl of comfort.
It is time for me to give the a try and I love your veggie load version! Have fun skiing this weekend!
