Creamy Lasagna Soup
This creamy lasagna soup delivers all the rich, comforting flavors of classic baked lasagna in a fraction of the time, made in just one pot.
- Cooking the noodles separately prevents them from absorbing all the soup broth and turning mushy.
- Searing the tomato paste in hot oil unlocks oil-soluble flavor compounds for a deeply rich base.
- A dollop of seasoned ricotta stirred in at the end mimics the creamy layers of a classic baked lasagna.
I still remember the Tuesday night my third-tier lasagna pan buckled in the oven, sending a wave of bubbling marinara directly onto the heating element. The smoke alarm shrieked, my dog hid under the couch, and I ended up scraping charred cheese off the oven floor with a metal spatula until my knuckles were raw.
That disaster cured me of making traditional layered lasagna on weeknights forever. I needed those exact comforting flavors, but without the structural engineering.
Most quick lasagna soups fail because home cooks treat them like a standard vegetable soup, dumping the pasta directly into the broth to boil. This is a massive mistake because the starches gelatinize and turn the liquid into a thick, gummy paste after just an hour in the fridge.
The fix is incredibly simple: boil your broken lasagna noodles separately, or stir them in at the absolute end. This keeps the broth beautifully silky while letting the pasta retain its perfect al dente bite.
Trust me on this one.
When I first started testing this, I tried using the same meat blend I use in my Stuffed Manicotti in Meat Sauce. But soup requires a lighter touch, so I swapped heavy beef for sweet Italian sausage to get those built-in fennel notes.
You want to brown the meat aggressively in your Dutch oven until a deep, golden crust forms on the bottom. Tap your wooden spoon against the pot to scrape up those caramelized bits—that is pure flavor.
It makes all the difference.
If you love the cheesy, comforting vibe of Million Dollar Spaghetti, you will lose your mind over the ricotta topping here. We whip it with parmesan, fresh herbs, and a pinch of salt to create a velvety cloud that melts into the hot broth.
Creamy Lasagna Soup
Ingredients
- 1 tbsp olive oil
- 1 lb sweet Italian sausage, casing removed
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 2 tbsp tomato paste
- 1 tsp dried oregano
- 1/2 tsp red pepper flakes
- 4 cups low-sodium chicken broth
- 1 can (14.5 oz) crushed tomatoes
- 8 oz lasagna noodles, broken into bite-sized pieces
- 1/2 cup heavy cream
- 1 cup ricotta cheese
- 1/2 cup grated parmesan cheese
- 1 tbsp Diamond Crystal kosher salt (or 1.5 tsp fine sea salt)
- 1/4 cup fresh basil, chopped
Directions
- Heat olive oil in a large Dutch oven over medium-high heat. Add the Italian sausage and cook, breaking it up with a wooden spoon, until browned and cooked through (about 6-8 minutes).
- Stir in the diced onion and garlic. Cook for 3-4 minutes until the onion is translucent and soft.
- Add the tomato paste, dried oregano, and red pepper flakes. Stir constantly for 2 minutes to caramelize the tomato paste and bloom the spices in the fat.
- Pour in the chicken broth and crushed tomatoes. Bring the mixture to a boil, then reduce heat to low and let it simmer for 15 minutes to allow the flavors to meld.
- While the soup simmers, cook the broken lasagna noodles in a separate pot of salted boiling water until al dente. Drain and set aside.
- Stir the heavy cream and cooked noodles into the soup. Simmer for an additional 2 minutes until heated through.
- In a small bowl, mix the ricotta, grated parmesan, and a pinch of salt. Serve the soup hot, topped with a generous dollop of the ricotta mixture and fresh basil.
Notes
- Always use Diamond Crystal kosher salt; if you are using Morton's or fine table salt, cut the volume by half to avoid an over-salted broth.
- Searing the tomato paste until it turns a deep brick-red color is crucial because it triggers the Maillard reaction and dissolves oil-soluble flavor compounds that water-based broth cannot extract.
- Do not leave the garlic in the pot unattended while browning; garlic burns in under thirty seconds, turning bitter and ruining the entire base of your soup.
- If you plan to have leftovers, store the noodles separately from the broth; otherwise, the pasta will continue to absorb liquid overnight and swell into a bloated, mushy mess.
Serving Suggestions
Complete this comforting meal by pairing it with fresh, vibrant sides that cut through the rich, creamy broth.
- A crisp, refreshing Italian Chopped Salad tossed in a tangy vinaigrette.
- Warm, garlic-butter brushed baguette slices for dipping.
- A side of roasted green vegetables like broccoli or asparagus.
- An extra sprinkle of crushed red pepper flakes for those who love heat.
Storage and Reheating
Store any leftover soup broth in an airtight container in the fridge for up to four days. Keep the cooked lasagna noodles in a separate container so they do not absorb the liquid and bloat.
Keep them separate.
Reheat the broth in a saucepan over medium heat until bubbling. Drop the cold noodles directly into your bowl and ladle the hot soup over them.
It tastes even better the next day.
Ingredient Substitutes
If you need to swap ingredients based on what is in your pantry, here are the best tested alternatives.
- Italian Sausage: Swap with ground turkey or chicken sausage for a lighter option.
- Lasagna Noodles: Use mafalda or campanelle pasta if you do not want to break up sheets.
- Heavy Cream: Sub with whole milk or half-and-half, though the broth will be slightly less velvety.
- Ricotta: Use cottage cheese blended until smooth if you prefer a higher-protein alternative.
This soup has completely replaced my weekend lasagna project, and honestly, nobody in my house is complaining. It gives you all the cheesy, saucy comfort of the classic dish in under forty minutes, without a single charred pan to scrub.

I've been developing recipes for about 12 years, and this one went through the same routine as everything else here: I made it, changed something, made it again, then had someone else cook it from just the written steps to see where it tripped them up. That's the part I care about most – not just that a recipe works for me, but that it works on a Tuesday night in your kitchen too.
