One Pot Lasagna Soup Recipe brings all the cheesy, saucy comfort of classic lasagna to one cozy pot, no layering drama required. I lean on this soup when I want big flavor without a sink full of dishes. It tastes rich and hearty, and it checks every weeknight dinner box.
Why You Should Try One Pot Lasagna Soup Recipe
I love this recipe because it nails that lasagna flavor with a fraction of the work. You brown sausage, simmer a tomato-rich broth, and drop in broken noodles done. I top bowls with a ricotta cloud, melty mozzarella, and a shower of Parm, and everyone thinks I slow-cooked all day.
I keep this one pot lasagna soup friendly to weeknights and picky eaters. The broth tastes bright and savory, the noodles stay tender, and the cheesy topping makes each spoonful feel special. I also scale it up for guests because the pot stretches easily, and nobody leaves hungry.
Ingredients You’ll Need
The soup:
- 1 tablespoon olive oil
- 1 pound Italian sausage (mild or hot), casings removed
- 1 medium yellow onion, diced
- 4 garlic cloves, minced
- 2 tablespoons tomato paste
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon crushed red pepper flakes (optional)
- 6 cups low-sodium chicken broth (or beef broth for richer flavor)
- 1 can (28 ounces) crushed tomatoes
- 8–10 dry lasagna noodles, broken into pieces (about 8 ounces)
- 2 cups baby spinach or chopped kale
- Kosher salt and black pepper, to taste
The cheesy topping:
- 1 cup whole-milk ricotta
- 1 cup shredded low-moisture mozzarella
- 1/2 cup freshly grated Parmesan
- 1 teaspoon lemon zest (optional but bright and lovely)
- Chopped fresh basil or parsley, for garnish
How to Make One Pot Lasagna Soup
- Brown the sausage: Heat olive oil in a large pot over medium-high. Add sausage and cook until browned, 5–7 minutes, breaking it up as it cooks.
- Build flavor: Add onion and sauté until translucent, 3–4 minutes. Stir in garlic and cook 30 seconds. Add tomato paste and cook, stirring, until it darkens and smells sweet, about 1–2 minutes.
- Simmer the base: Stir in oregano, basil, and red pepper flakes. Pour in broth and crushed tomatoes, scrape up any browned bits, and bring to a simmer.
- Cook the noodles: Add broken lasagna noodles and stir. Simmer, stirring occasionally, until the noodles turn al dente, about 10–12 minutes.
- Finish the soup: Stir in spinach or kale and cook just until it wilts, 1–2 minutes. Taste and season with salt and pepper.
- Mix the cheesy topping: In a bowl, stir together ricotta, half the mozzarella, Parmesan, lemon zest, a pinch of salt, and a little pepper.
- Serve: Ladle soup into bowls. Dollop the ricotta mixture on top, finish with the remaining mozzarella, and shower with fresh basil or parsley.
Cooking Tips
- Break noodles small: Aim for 1–2-inch pieces so they sit nicely on a spoon. I find that size gives you the best slurp-to-chew ratio.
- Stir noodles early and often: They like to stick. Give the pot a few good stirs during the first minutes of simmering.
- Salt at the end: Broth and sausage vary in saltiness. Taste before you add extra salt, and adjust slowly.
- Cheesier bowls: Slide hot bowls under the broiler for 1–2 minutes to melt and brown the mozzarella. Use broiler-safe bowls and watch closely.
Serving
I love a crisp green salad with a zippy vinaigrette to balance the richness. Garlic bread or a warm baguette turns this into a full comfort-meal situation. I also set out crushed red pepper, extra Parm, and basil so everyone can build their perfect bowl. If you sip wine, pour a Chianti or Sangiovese to match the tomato backbone.
Mistakes to Avoid
- Overcooking the noodles: You’ll end up with mush. Stop cooking when the noodles turn just al dente, because they keep softening in the hot soup.
- Skipping the tomato paste “toast”: Stir and cook it until it darkens. You pull out a deeper, rounder flavor that screams lasagna.
- Dumping greens too early: Stir spinach or kale in at the end. You keep the color bright and the texture pleasant.
- Overloading the pot with noodles: They expand a lot. Use the amount listed, and add more only if you want a thicker stew vibe.
Substitutions
- Protein swaps: Use ground turkey, chicken sausage, or plant-based crumbles. I also mix half sausage and half beef when I want classic lasagna flavor.
- Noodle tweaks: Use regular lasagna noodles, mafalda, farfalle, or even rotini. Break lasagna sheets into bite-size pieces for the proper spoon feel.
- Dairy-free: Use almond-based ricotta and skip mozzarella, or use a good dairy-free melt. The soup still tastes rich thanks to the sausage and tomatoes.
- Veggie boost: Add diced zucchini, mushrooms, or bell pepper with the onions. I toss in extra spinach when I feel virtuous.
- Heat level: Add more red pepper flakes or finish bowls with Calabrian chile oil. I keep the base mild and let spice-lovers doctor their bowls.
Make-Ahead and Storage Tips
This lasagna soup reheats so well that it’s one of my go-to lunch meal-prep recipes.
Make-Ahead: Cook the soup and undercook the noodles by 1–2 minutes. Or cook the soup base without noodles, cool it, and boil fresh noodles when you reheat for the best texture.
To Refrigerate: Store cooled soup in airtight containers for up to 4 days. If you stored the noodles separately, keep them in a second container and combine as you reheat.
Freezing: Freeze the soup base without noodles for up to 3 months. Thaw in the fridge overnight, then simmer and add fresh noodles.
To Reheat: Warm in a saucepan over medium heat, stirring occasionally, until hot. Add a splash of broth if it thickens, and finish with the ricotta topping right before serving.
