It’s your new go-to for a hearty, family-friendly meal that’s ready in under an hour. That rich, cheesy tomato goodness just screams comfort, making it the perfect Italian sausage soup for any cozy fall dinner. Adding that dollop of ricotta or pesto? Chef’s kiss!

Gather Your Ingredients for Lasagna Soup

Alright, let’s get this party started! To whip up this amazing lasagna soup, you’ll want to gather a few things. Don’t worry, it’s all pretty standard stuff you probably have in your pantry or can snag easily at the store. Grab about a tablespoon of olive oil to get things going.

For the star of the show, we need one pound of Italian sausage – and trust me, make sure to remove the casings! You’ll also need one medium onion, all chopped up, and about two cloves of garlic, minced super fine. For those classic Italian herbs, grab a teaspoon of dried oregano and another teaspoon of dried basil. If you like a little kick, a half teaspoon of red pepper flakes is totally optional but highly recommended!

For the saucy base, we’ll need four cups of chicken broth, one big 28-ounce can of crushed tomatoes, and a 15-ounce can of tomato sauce. Don’t forget about seasonings – about a teaspoon of salt and a half teaspoon of black pepper, plus whatever you feel like adding. And of course, the star pasta: one cup of lasagna noodles, broken into bite-sized pieces. Lastly, for that creamy, cheesy finish, have a half cup of heavy cream, a half cup of shredded mozzarella cheese (plus more for topping, obviously!), and a quarter cup of grated Parmesan cheese (more for topping too!). Oh, and some fresh basil for a pretty garnish, and maybe some ricotta cheese or pesto to dollop on top if you’re feeling fancy!

Step-by-Step Guide to Making Lasagna Soup

Alright, let’s get this party started! To whip up this amazing lasagna soup, you’ll want to gather a few things. Don’t worry, it’s all pretty standard stuff you probably have in your pantry or can snag easily at the store. Grab about a tablespoon of olive oil to get things going.

For the star of the show, we need one pound of Italian sausage – and trust me, make sure to remove the casings!

Browning the Sausage and Aromatics

First things first, heat that olive oil in a big pot or Dutch oven over medium-high heat. Toss in your Italian sausage and get it cooking, breaking it up with your spoon until it’s all nicely browned. This step is crucial for building that deep sausage flavor! Scoop out the sausage with a slotted spoon and set it aside, but don’t drain all those flavorful drippings – we need ’em!

Building the Flavor Base for Your Lasagna Soup

Now, throw your chopped onion into the pot with those drippings and cook until it’s nice and soft, usually about 5 minutes. Next, add in your minced garlic, dried oregano, dried basil, and those optional red pepper flakes if you’re feeling brave. Cook for another minute until everything smells amazing. Then, pour in the chicken broth, crushed tomatoes, and tomato sauce in one go. Give it a good stir, scraping up any browned bits from the bottom – that’s pure flavor gold! Season it all with your salt and pepper.

Cooking the Noodles to Perfection

Bring that bubbling mixture to a simmer, then stir in those broken lasagna noodles. You’ll want to cook these according to the package directions, but usually, it’s about 10-12 minutes until they’re perfectly al dente. Give them a stir now and then to make sure they don’t stick together or to the bottom of the pot, because nobody wants gummy noodles in their soup!

Finishing Touches for Creamy Lasagna Soup

Almost there! Stir in that browned Italian sausage you set aside earlier. Now for the creamy goodness: add your heavy cream, shredded mozzarella cheese, and grated Parmesan cheese. Just keep stirring gently until the cheeses are all melted and gooey and the soup is heated through. It only takes a couple of minutes, and wow, does it transform the soup!

Tips for the Best Lasagna Soup Experience

Alright, let’s talk about making this lasagna soup absolutely perfect! It’s all about those little details, you know? For starters, don’t overcook those noodles. I know how tempting it is to let them simmer until they’re super soft, but for soup, you want them just right – that amazing al dante bite. It makes all the difference!

Achieving Perfect Noodle Texture

Seriously, watch those noodles! You want them tender but with a slight chew. Check them a minute or two before the package says and give them a taste. Mushy noodles are a no-go for this soup; they just get lost. A little bite keeps the soup interesting!

Customizing Your Lasagna Soup

Don’t be afraid to play around! This recipe is super forgiving. Add some chopped zucchini or mushrooms with the onions, or maybe toss in a can of diced tomatoes for extra texture. And that sprinkle of ricotta or a swirl of pesto on top? Totally non-negotiable in my book for that extra creamy, dreamy finish!

If you love quick and easy meals like this delicious dinner recipe, you’re in the right place!

Make-Ahead and Storage for Lasagna Soup

Honestly, this lasagna soup is a lifesaver because it’s totally make-ahead friendly! If you’re planning ahead, you can totally make the soup base (up to step 3, before adding the noodles) and let it cool completely. Then, just pop it into an airtight container and stash it in the fridge for up to 3 days. When you’re ready to serve, reheat that base on the stovetop, stir in your noodles, cream, and cheeses, and cook like normal. It’s like having a little bit of magic ready for you whenever hunger strikes, perfect for those grab-and-go lunch recipes!

Freezing works too! Just make sure to cool the soup completely before freezing any extra portions. When you’re ready, thaw it in the fridge overnight and then reheat on the stove, adding the noodles and cream/cheeses at the end for the best texture.

Frequently Asked Questions About Lasagna Soup

Got questions? I’ve got answers! This lasagna soup is seriously so versatile, but here are a few things folks often ask:

Can I make this Lasagna Soup vegetarian?

Absolutely! Just skip the Italian sausage and sauté some extra veggies like diced zucchini, mushrooms, or bell peppers with the onions. You could also use a plant-based Italian-style sausage crumble for a similar flavor profile. It’s still going to be delicious!

What kind of noodles work best for Lasagna Soup?

For this soup, breaking up regular lasagna noodles into smaller pieces is a classic! They give that perfect bite and soak up all the yummy flavors. You could also use other short pastas like rigatoni, penne, or even ditalini if you can’t find lasagna sheets. Just make sure they’re broken up so they cook evenly!

How do I store and reheat Lasagna Soup?

This soup stores like a dream! Let it cool completely, then pop it into an airtight container in the fridge for up to 3 days. When you reheat, I like to do it gently on the stovetop, adding a splash more broth or water if it’s too thick. The noodles might get a little softer, but it’s still super tasty!

Estimated Nutritional Information

Just a heads-up, the nutritional info for this lasagna soup is an estimate, okay? It can totally change depending on the brands you use, the exact amount of sausage, or even how much cheese you sprinkle on top! But generally, a serving is around 450 calories, with about 25g of fat (10g saturated), 20g of protein, and 35g of carbs.

Ingredients

Scale
  • 1 tablespoon olive oil
  • 1 pound Italian sausage, casings removed
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon red pepper flakes (optional)
  • 4 cups chicken broth
  • 1 (28 ounce) can crushed tomatoes
  • 1 (15 ounce) can tomato sauce
  • 1 teaspoon salt, or to taste
  • 1/2 teaspoon black pepper, or to taste
  • 1 cup lasagna noodles, broken into pieces
  • 1/2 cup heavy cream
  • 1/2 cup shredded mozzarella cheese, plus more for topping
  • 1/4 cup grated Parmesan cheese, plus more for topping
  • Fresh basil, chopped, for garnish
  • Ricotta cheese or pesto, for dolloping (optional)

Instructions

  1. Heat olive oil in a large pot or Dutch oven over medium-high heat. Add Italian sausage and cook, breaking it up with a spoon, until browned. Remove sausage with a slotted spoon and set aside, leaving drippings in the pot.
  2. Add chopped onion to the pot and cook until softened, about 5 minutes. Add minced garlic, dried oregano, dried basil, and red pepper flakes (if using) and cook for 1 minute more until fragrant.
  3. Pour in chicken broth, crushed tomatoes, and tomato sauce. Stir to combine, scraping up any browned bits from the bottom of the pot. Season with salt and pepper.
  4. Bring the soup to a simmer, then stir in the broken lasagna noodles. Cook according to package directions, or until noodles are al dente, about 10-12 minutes. Stir occasionally to prevent sticking.
  5. Stir in the cooked Italian sausage, heavy cream, shredded mozzarella cheese, and grated Parmesan cheese. Cook until the cheeses are melted and the soup is heated through, about 2-3 minutes.
  6. Ladle the soup into bowls. Garnish with extra mozzarella cheese, Parmesan cheese, fresh basil, and a dollop of ricotta cheese or pesto, if desired.

Notes

  • For a slow cooker version, brown the sausage and sauté the onion and garlic on the stovetop first. Transfer to a slow cooker along with broth, tomatoes, tomato sauce, seasonings, and lasagna noodles. Cook on low for 4-6 hours or high for 2-3 hours, until noodles are tender. Stir in cream and cheeses during the last 30 minutes of cooking.
  • This soup can be made ahead. Prepare the soup up to step 3, then cool and refrigerate. When ready to serve, reheat the base, add the noodles, cream, and cheeses, and cook as directed.
  • Adjust seasonings to your preference. Add more herbs or a pinch of sugar to balance the acidity of the tomatoes.
