Description

All the cozy, layered flavors of classic lasagna—packed into a hearty, weeknight-friendly soup. You’ll simmer Italian sausage with tomatoes, aromatics, and broken lasagna noodles, then crown each bowl with a creamy ricotta-mozzarella-Parmesan topping that melts into silky, cheesy swirls. One pot. Under an hour. Pure comfort.


Ingredients

For the Hearty Soup Base:

  • 2 pounds Italian sausage (sweet, hot, or a mix)

  • 1 medium onion, diced

  • 5 cloves garlic, minced

  • 4 cups low-sodium beef broth

  • 1 (15 oz) can tomato sauce

  • 2 (15 oz) cans diced tomatoes (fire-roasted recommended)

  • 1 tablespoon Italian seasoning

  • 1 teaspoon black pepper

  • 2 bay leaves

  • 8-10 sheets lasagna noodles, broken into bite-size pieces

For the Cheesy Ricotta Topping:

  • 16 oz whole-milk ricotta cheese

  • 1 cup shredded mozzarella cheese

  • 1 cup grated Parmesan cheese

  • 1 tablespoon Italian seasoning


Instructions

  1. Brown the sausage & aromatics
    In a large pot or Dutch oven over medium-high heat, cook the Italian sausage, breaking it into crumbles, until browned (about 8–10 minutes). Spoon off excess fat, leaving about 1–2 tablespoons in the pot. Add the diced onion; cook until translucent (about 5 minutes). Stir in garlic; cook 1 minute until fragrant.
  2. Build the savory soup base
    Reduce heat to medium. Stir in beef broth, tomato sauce, and diced tomatoes. Add Italian seasoning, black pepper, and bay leaves. Bring to a gentle simmer; cook 15 minutes to meld flavors.
  3. Cook the lasagna noodles
    Option A (serve now): Add broken lasagna noodles directly to the simmering soup; cook, stirring occasionally, until al dente per package time.
    Option B (best for leftovers): Boil noodle pieces separately in salted water until al dente. Drain and toss with a little olive oil to prevent sticking. Add to bowls when serving.
  4. Make the ricotta topping
    In a bowl, mix ricotta, mozzarella, Parmesan, and Italian seasoning until well combined.
  5. Assemble & serve
    Ladle hot soup into bowls. Add a handful of noodle pieces (if cooked separately). Dollop a generous spoonful of the ricotta mixture on top; let it melt into the soup. Serve immediately.

Notes

  • Noodle strategy: For the best leftovers, cook noodles separately and add to each bowl as you serve.
  • Broth swap: Chicken or vegetable broth works in a pinch.
  • Add greens: Stir in a few handfuls of baby spinach during the last 2 minutes of simmering.
  • Lighter option: Use turkey Italian sausage and part-skim ricotta/mozzarella.
  • Make-ahead: Soup base keeps 3–4 days refrigerated. Store noodles and cheese mixture separately.
  • Toppings: Fresh basil, extra Parmesan, or a pinch of red pepper flakes are great finishing touches.
