How to Make One-Pot Lasagna Soup Recipe
Brown the sausage, 5 to 7 minutes
Heat the olive oil over medium-high in a Dutch oven. Add the sausage and break it into crumbles. Cook until browned with crispy edges and no pink remains. Spoon off excess fat if it looks greasy, but keep about 1 tablespoon for flavor.
Build the savory base, 3 to 4 minutes
Add the diced onion and stir until it softens and turns glossy. Add the garlic and cook 30 seconds until fragrant. Stir in the tomato paste and toast it until it darkens slightly and smells sweet.
Add liquids and season, bring to a simmer
Pour in crushed tomatoes, broth, and the cup of water. Stir in oregano, basil, fennel seeds, red pepper flakes, sugar, salt, and pepper. Bring the pot to a lively simmer.
Cook the noodles to al dente, 12 to 14 minutes
Snap the lasagna noodles into pieces and drop them into the simmering soup. Stir well so pieces do not stick. Cook at a steady simmer until the pasta turns al dente and releases starch that slightly thickens the soup. Add a splash of water if the pot looks too tight.
Make the ricotta topping, 2 minutes
In a small bowl, mix ricotta with half the parmesan, a pinch of salt, and black pepper. Stir until smooth and spreadable.
Finish the pot, 2 to 3 minutes
Fold in spinach to wilt. Stir in cream if you want a silky finish. Taste and adjust salt, pepper, and heat. Pull the pot off the heat and add lemon zest if you like a bright pop.
Serve with the cheeses
Ladle soup into bowls. Top each bowl with a generous dollop of ricotta, a sprinkle of mozzarella, and extra parmesan. Shower with fresh basil or parsley.
Tips & Common Mistakes
- Salt in layers and taste as you go to keep flavors balanced.
- Toast the tomato paste so you build sweetness and depth.
- Break noodles into similar sizes so they cook evenly.
- Stir the pot after adding noodles so pieces do not clump.
- Keep the simmer gentle to prevent blowouts and broken noodles.
- Thin the soup with water or broth if it tightens more than you like.
- Add cream at the end so dairy does not split.
- Dollop ricotta right before serving so it stays plush.
- Use low sodium broth and adjust salt at the end for control.
- Skip spinach until the finish so it stays green.
- Store noodles separate if you plan for leftovers so they keep a better bite.
Variations I've Tried
- Veggie version: swap sausage with cremini mushrooms and a can of lentils; use vegetable broth.
- Chicken sausage: mild links out of the casing add lean protein and fennel kick.
- Spicy kick: stir in a teaspoon of Calabrian chile paste with the tomato paste.
- Gluten free: use sturdy gluten free pasta shapes and cook slightly shy of al dente.
- Dairy light: use part-skim ricotta and skip cream; finish with extra olive oil.
- Extra hearty: add a small rind of parmesan while simmering and fish it out before serving.
How to Serve
Ladle the lasagna soup into warm bowls and crown it with ricotta, mozzarella, and parmesan. Add a drizzle of good olive oil and a scatter of basil for that trattoria glow. Serve with garlic bread, a crisp green salad, and something bubbly like sparkling water with lemon. A medium-bodied red like Sangiovese also pairs nicely with the tomato base.
Make-Ahead and Storage
- Make ahead: cook the soup base and stop before adding pasta; chill up to 4 days or freeze up to 3 months. Boil fresh noodles when you reheat so the texture stays al dente.
- Fridge: store cooked soup with noodles up to 3 days; the pasta will keep softening, so plan a firmer cook on day one.
- Freezer: freeze the soup base without pasta up to 3 months; add fresh noodles after thawing and reheating.
- Reheat: warm on the stovetop over medium with a splash of broth or water until steamy. In the microwave, heat in short bursts and stir between rounds to keep the cheese from overheating.
