January always feels like the longest and the coldest month to me — last year I think we had FIVE extreme cold, no-school days just in January alone.

While I’m hoping for a better January this year, I’m definitely prepared for the cold with this easy Lasagna Soup.

I have one soup hater in my house, much to my dismay. But even my 4 year old who normally turns up her nose at any kind is in love with this hearty, meaty, cheesy soup!

There are a few key ingredients in this Lasagna Soup — mild Italian sausage (or sub ground beef if you prefer less spice), tomatoes, tomato sauce, Italian herbs and a good amount of cheese — but it’s the curly lasagna noodles that really catch the eye of my picky eaters.

With a 2, a 5 and a 7 year old, life gets a little crazy around here and we look to hearty wheat recipes to fuel our busy family! Whole grain breads, pasta, hearty muffins, pancakes for a quick dinner or a cheese-and-crackers lunch when we’re short on time.

Wheat is Life’s Simple Ingredient and one that is a big part of almost every meal around here!

Tips for making the best Lasagna Soup:

  • Choose your meat: Italian sausage (mild or spicy), ground beef, or even ground turkey or chicken would work in here, and you can choose any of them depending on your tastes and your lifestyle. I prefer Italian sausage because of the extra flavor it adds!
  • Choose your pasta: white or whole grain lasagna noodles will work just as well in this Lasagna Soup — just keep in mind that whole grain will take longer to cook and may absorb additional liquid.
  • Plan ahead: the incredible flavor in this soup comes from adequate time simmering away, so this is one crockpot soup recipe that can be left cooking all day, and all you have to do when you come home is stir in the noodles and wait until they are tender.

Variations on this Crockpot Lasagna Soup recipe:

  • Make this soup recipe gluten free by substituting gluten free pasta or lasagna noodles: you will want to cook these in a separate pot of boiling water and stir them in at the end.
  • Make this soup recipe dairy free by using dairy-free or vegan cheese (or omitting altogether)
  • Make this soup vegetarian by using vegetable broth, omitting the meat and adding in extra vegetables like sliced zucchini, mushrooms and bell peppers.
  • Bump up the spice by adding a pinch of cayenne or red pepper flakes, or by choosing spicy Italian sausage
  • Lower the fat by choosing Italian turkey sausage
  • Don’t have frozen spinach? Toss in a handful of fresh spinach at the end.

How to make this Lasagna Soup in the Instant Pot:

Making this Lasagna Soup in the Instant Pot instead of the Crockpot couldn’t be easier! The best part is that you don’t need a separate pan to cook the meat.

  1. Cook Italian sausage and onion on saute until browned. Stir in the spices and seasonings.
  2. Turn Instant Pot off, and add broth. Scrape the bottom to remove any browned bits.
  3. Add tomatoes, tomato sauce, spinach and noodles.
  4. Put the lid on, turn the valve to sealing, and pressure cook on high for 3 minutes.
  5. Let the pressure release naturally for 5 minutes, then open and serve.

How to store Crockpot Lasagna Soup:

In the refrigerator:

If you happen to have leftover Lasagna Soup, you can store in the refrigerator for 3-4 days in an airtight container

In the freezer:

You can absolutely freeze this lasagna soup for later! One thing you need to remember is that frozen and thawed pasta is softer than the first time around, and if you like your pasta with a bite then this may not be the best option for you.

If you prefer, you can cook the noodles separately and add in just when you want to serve — this way, you can easily freeze any leftovers and add the pasta in later.

Servings 4 servings
Calories 674cal


  • 1 lb mild Italian sausage casings removed
  • 1 medium onion finely chopped
  • 2 teaspoons minced garlic
  • Seasoning: Italian seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 3 cups low-sodium chicken broth
  • 398 ml canned diced tomatoes Italian style (14oz)
  • 1 ½ cups jarred tomato pasta sauce
  • 2 cups short pasta or 8 broken lasagna noodles of about 160 grams
  • cups fresh spinach* or sub ⅓ cup frozen, thawed and squeezed dry
  • ricotta shredded mozzarella, parmesan cheese, and fresh parsley for serving


  • In a medium skillet, cook Italian sausage and onion over medium-high heat until sausage is browned, stirring often.
  • Stir in garlic, Italian seasoning, salt, and pepper. Pour into a 4-6 quart crockpot.
  • Add broth, tomatoes, and pasta sauce. Cover and cook on low for 3-6 hours or high for 2-3 hours (everything is cooked — this is just so it heats through and the flavors come together).
  • Turn the slow cooker to high, open the lid, stir in the pasta, and cook for 30 minutes or until tender. (OPTIONAL: you can also cook the pasta separately if you prefer your noodles to stay at al dente).
  • Just before serving, stir in spinach. Serve with cheese and fresh parsley as desired.


  • Spinach: Fresh spinach wilts quickly, so we add it at the end. If you’re using frozen spinach, thaw it and squeeze some liquid out of it, then you can add it with the tomato sauce or at the end, shortly before serving.
  • Store: Store leftover lasagna soup in an airtight container in the refrigerator for up to 4 days.
  • Freeze: Freeze this soup in a freezer-safe container or in freezer bags in the freezer for up to 3 months. Fully thaw before reheating, and ensure it is cooked through and piping hot before serving. Frozen and thawed pasta is often softer than when it is freshly cooked. If you like your pasta with a bite, then this may not be the best option for you. If you prefer, you can cook the pasta separately and add them in when you want to serve the soup. You can easily freeze any leftovers and add the pasta later if you do this.

    I made this last night in my Instant Pot and it was delicious! I’m sure it is tasty in the slow cooker but it was soooo simple, super fast and tasty in the IP that I’m sorry to say I likely will never try the original version lol!
