Lasagna has been a beloved Italian dish for centuries, and for good reason – it’s utterly delicious! The only downside to this rich, layered meal is how much time it takes to make. So, to bring you all of the yummy goodness of lasagna in a fraction of the time, we created the perfect solution in our one-pot Deconstructed Lasagna Soup recipe!

With Italian sausage, noodles, mushrooms, spinach, spices, and a nice dollop of ricotta, it’s easy to enjoy all of the heartwarming flavors of lasagna in just 40 minutes (or less with our smart prep tips below).

Another exciting element of this soup is that it’s a great freezer-friendly meal – just cook the noodles separately after taking the rest of the soup out of the freezer. With so much flavor and convenience packed into one quick dish, it’s no wonder it is a community favorite that ranked #3 in our Top 10 Recipes of 2018.

“So easy and came together pretty quick, and in just one pot!! Loved that this tasted like lasagna but not quite so heavy.”

Meal Planning Smarts

  • Budget Cooking: While our weekly meals always help you save money, if you want to save a little extra this week, we have a great budget option for this recipe! Since meat is consistently more expensive than its alternatives, you can cut that grocery bill by using a can of white beans (such as navy or cannellini beans) or lentils instead. Beans and lentils will compliment the flavors in this soup wonderfully and provide a hearty finish that will keep you satisfied for hours.
  • Time-Savers: If you’re pressed for time this week, you can reduce your time in the kitchen by buying pre-sliced mushrooms. Another thing that can help you save a little time is our prepping smarts below.

Lasagna Soup with Italian Sausage

Classic lasagna is time-consuming to make, but all those same ingredients can be made into soup in a fraction of the time! A dollop of ricotta cheese served on top gives this dish the authentic feel of the original dish.

Prep time: 10 min

Cook time: 30 min

Total time: 40 min

Serves: 4


  • Onions, medium - 1, diced
  • Garlic - 4 cloves, chopped
  • Lasagna noodles - 6 oz, broken into pieces
  • Mushrooms, any button - 8 oz, sliced (look for pre-sliced)
  • Oil, cooking - 1 Tbsp
  • Sausage, Italian and raw (use mild or spicy) - 8 oz
  • Tomato paste - 2 Tbsp
  • Oregano, dried - 1 tsp
  • Basil, dried - 1/2 tsp
  • Italian seasoning - 1/2 tsp
  • Red pepper flakes (opt) - 1/2 tsp
  • Stock, any type - 4 cups
  • Tomatoes, diced and preferably fire-roasted (14 oz / 397 g) - 1 can
  • Bay leaves - 2
  • Spinach, baby - 5 oz
  • Cheese, ricotta - 1/4 cup
  • Cheese, parmesan (opt) - 2 oz, grated



  1. Onions / Garlic / Lasagna noodles – Prep as directed. Store separately. (Can be done up to 5 days ahead)
  2. Mushrooms – Slice mushrooms. (Can be done up to 3 days ahead)


  1. Heat a Dutch oven with oil over medium heat. Stir in onions, garlic, and mushrooms and cook for 2 to 3 minutes.
  2. Add sausage and saute until sausage is breaking apart and nearly cooked through, 4 to 6 minutes.
  3. Stir in tomato paste, oregano, basil, Italian seasoning, and red pepper flakes and saute until fragrant, ~1 minute more.
  4. Pour stock and tomatoes (including liquid) over sausage and aromatics. Add bay leaves. Bring to a simmer.
  5. Stir lasagna noodles into soup and cover.
  6. Simmer soup just until lasagna noodles are al dente, tender but still with some bite. This should take 10 to 15 minutes, but watch closely to prevent over-cooking the noodles. In the last minute of cooking, stir in spinach leaves.
  7. Taste soup and season with some salt and pepper.
  8. Divide soup between serving bowls. Top each bowl with a spoonful of ricotta cheese and some Parmesan cheese (if using). Enjoy!
