Slow Cooker Lasagna Soup is a delicious, convenient way to enjoy the flavors of lasagna without all the work. Start with just 10 minutes of prep, then set it and forget it in the slow cooker.

This easy lasagna soup recipe is a family favorite, and I mean extended family. My cousin, a high school teacher in Georgia, often has his students make this recipe, and I get to see the pictures! It’s great.
I love the recipe because it’s all the best flavors of lasagna but cooked in a slow cooker. It’s cheap, delicious, and easy to make, and that’s exactly what I want out of my cold-weather food these days!

At a Glance: Here is a quick snapshot of what ingredients are in this recipe.
Please see the recipe card below for specific quantities.
Ingredient notes
- Italian sausage: Ground beef or ground turkey may be substituted for the Italian sausage. If you use lean meat, add olive oil to the pot before cooking it. In a pinch, you could also chop up Italian sausage links.
- Mushrooms: Unless it’s a Stuffed Mushrooms recipe, I feel like mushrooms are always optional (people either love them or hate them). Don’t put them in if it will take away your joy. It’s as simple as that.
- Italian herbs: To make your own homemade Italian seasoning, combine equal parts of dried basil, marjoram, oregano, rosemary, and thyme. Store extra seasoning covered in the pantry for up to 6 months.
- Lasagna noodles: Put those leftover lasagna noodles from your pantry to work in this Lasagna Soup (the regular lasagna noodles, not no-bake). Just break the dry noodles into bite-sized pieces. Or, substitute any other small pasta (radiatori and rotini are my favorites here).
Step-by-step instructions
- In a large pot or skillet over medium-high heat, combine sausage, onions, carrots, and garlic. Saute until the sausage has browned, breaking up clumps into smaller pieces with a wooden spoon and the vegetables have softened, about 5 to 7 minutes. Drain if desired.

- Meanwhile, to the slow cooker, add diced tomatoes and their juice, tomato sauce, mushrooms, Italian seasoning, basil, fennel, and salt and pepper to taste (I like 1 teaspoon salt and ½ teaspoon pepper). Stir in water and sausage mixture.

- Cover and heat on HIGH for 4 hours or LOW for 8 hours. During the last 10 minutes of cooking time, stir in the pasta, cover, and continue to cook until softened.

- Serve in bowls with mozzarella cheese, parmesan cheese, or even a spoonful of ricotta cheese and fresh parsley or basil if desired.

Recipe tips and variations
- Yield: This Crockpot Lasagna Soup recipe makes about 12 cups of soup, enough for 6 servings, 2 cups each.
- Storage: Store lasagna soup covered in the refrigerator for up to 4 days.
- Freezer: This is a great soup to freeze! For best results, omit the pasta before freezing. When it’s time to reheat the soup, boil the noodles separately and add them to the pot (or just stir them into the soup, but be mindful that they will soak up some of the liquid).
- Classic lasagna: My absolute favorite lasagna recipe is Make-ahead Lasagna. The noodles go in dry (uncooked) and you let the whole thing sit for a few hours. In that time, the noodles soften. It’s fabulous, and I think you’ll love it.
- Zucchini lasagna: Whether you’re cutting carbs or just trying to eat more veggies, Zucchini Lasagna is a delicious, hearty entree any time of year. Grilled ribbons of zucchini stand in for lasagna noodles, and with layers of ricotta and marinara-coated ground beef, you won’t even realize this is a low-carb casserole.
- Vegetable lasagna: Filled with spinach, mushrooms, ricotta, and an easy homemade tomato sauce, even carnivores will devour this Vegetable Lasagna recipe.
- Dessert lasagna: This easy no-bake Chocolate Lasagna recipe has an OREO cookie crust topped with sweetened cream cheese and chocolate pudding. Every bite is chocolatey, light, and absolutely fabulous.
- Stove Top Lasagna Soup: Ready in 30 minutes, my stovetop lasagna soup comes together for a quick family dinner.
- Bring 2 cups water and 1 teaspoon salt to boil. Add 8 ounces dry lasagna noodles (broken into pieces) and cook until al dente, about 8 minutes. Drain well and rinse in cold water to stop the cooking.
- Meanwhile, in a Dutch oven or large saucepan over medium-high heat, add 1 pound ground Italian sausage, 1 large onion (chopped), 3 carrots (peeled and diced), and 4 cloves garlic (minced). Cook until the sausage has browned and the vegetables have softened, about 5 to 7 minutes. Drain if desired.
- Add 4 cups water, 28 ounces Italian-style diced tomatoes and their juice, 14 ounces tomato sauce, 8 ounces mushrooms (sliced), 1 teaspoon Italian seasoning, ½ teaspoon dried basil, ½ teaspoon fennel seeds, and salt and pepper to taste (I like 1 teaspoon salt and ½ teaspoon pepper).
- Bring to a boil. Reduce heat, cover, and simmer until flavors have blended, about 15 to 20 minutes. Stir in drained pasta until heated through, about 5 minutes. Serve with mozzarella cheese and fresh basil if desired.

Frequently Asked Questions
It’s easy to make gluten-free lasagna soup. First, make sure your ground sausage is gluten-free. Then, substitute your favorite gluten-free noodles. I’ve really like the Barilla gluten-free noodles. They taste legit!
Shredded mozzarella cheese is a great topping for lasagna soup. I also love a dollop of ricotta, a sprinkle of Parmesan, and fresh herbs like basil and parsley.

So, so perfect for this rainy weather we are FINALLY having. I need to hit up the store and get this in the cooker pronto! Thanks for this one…
Hi Kevin, thank YOU for stopping by! It’s always so refreshing when the weather cools down in SoCal and we can pretend we have a season other than summer…. ha!
Great dish! It was a big hit with the whole family (including our 10 month old)….they’ve already asked for it again next week. We’re not sure what Christmas will be like this year with Steph’s work schedule, but I’m trying hard to get us to Wisco for a white Christmas!
Thank you so much, Joey! Here’s hoping we get to see you guys at Christmas. In the meantime, thank you SO MUCH for your support and love of this blog. Most of the people I know in real life don’t pay it half as much attention as you do! <3 XXO
Making this tomorrow! This time I’ll actually read how many noodle to add and not put in the entire box 🙂
Miss you!
Hey buddy! Thank you so much for the comment. And sorry for never replying to you on Instagram. 🙂 Are you guys going to be at G&Gs for Christmas Eve this year? We’d love to see you and will definitely be in town! Take care and hope to see you soon! Miss you too! XXO
This veers into genius territory.
Cakespy, you are too kind.
I’m all about slow cooker recipes this time of year! I’ve never had lasagna soup but it sounds like incredible comfort food! Pinned, of course.
I hope you are enjoying your new nest up in the Bay Area, Kathleen! I hear it’s chilly up there a lot, so hopefully you can find a time to make this one. Thanks for the pin, too! xoxo
Yum!!! What a splendid idea! This is going on my menu for next week. Thanks so much. I love your blog!
Wow, thank you Karen! I am so happy to hear that – ALL of it! 🙂 Thanks again!
This so much better than faffing (a British word for messing) around with lasagna, that’s why I don’t make it. But being the soup nut that I am, I will be making this.
You are seriously THE soup nut. Why bother with layering noodles when you can just dump it all in a pot and be done with it?
Oh, Meggan …. great minds or what?! I just posted an easy lasagna recipe too!
This idea of yours is amazing. I love the flavours of lasagna but really can’t be bothered to go to the trouble of making it very often. Love this dump in the slow cooker and wait version so much more. And I’ve been looking for more slow cooker ideas, too … bonus!
Ha ha Helen, there is definitely no disputing that we are both great minds! Or at least you are! This was so much easier, plus no baking in the oven and it was 100 degrees here today so… yeah. Slow cookers are just as useful in the summer as the winter!
Ok so yes havsies IS a word 🙂 And I do NOT think you will be jealous when I am freezing my bum off in Chicago and you are basking in the LA sun 🙂 This looks soo yummy! I am totally looking forward to making a vegan version of this!!! I love soups!!! LOVE!!!
Thanks, Mila! This would totally translate to vegan, so easily. And it would be SO good!!!!
Love your blog and all your recipes.
A new chain restaurant call “be good” has opened and my daughter is raving about the quinoa and kale bowls with ginger and almond. Do you have any recipes for this?
Thanks so much!
Hey there, thank you so much for your comment! I found a description online of this: “TOASTED ALMOND & GINGER
kale, sautéed veggies, bok choy, tamari almonds, red cabbage, enoki mushrooms, mint, toasted almond-ginger sauce” from a restaurant called B.Good. Sadly, I think it’s only in the New England and I’ve never eaten there! I could certainly make something using the ingredients they have listed, but without trying it myself I could never claim it was a “copycat.” So sorry about that! Thanks again for visiting my site!
