Lasagna is the dinner I love most and make least. All that boiling, layering, baking, and then waiting for it to cool so it doesn’t slide all over the plate. On a random Tuesday, I just don’t have that kind of patience.
So the first time Silas and I made lasagna soup in a tiny rental kitchen with exactly one decent pot, I honestly didn’t expect much. Twenty minutes in, Silas wandered over, sniffed the air, and asked if I’d secretly made real lasagna.
Nope. Same cozy flavors, same melty cheese, way less work.
And every bowl ends with a creamy, cheesy dollop that slowly melts into the tomato broth while you eat. (That dollop is the whole reason I make it, by the way.)
Below is my go-to cheesy lasagna soup, plus the one mistake that turns the noodles into mush. I learned that one the hard way, so you won’t have to.
Why Lasagna Soup Is Still Everywhere in 2026
This isn’t some internet fad that fizzled out after a week. Lasagna soup blew up on TikTok back in 2023, and it comes roaring back every single fall once soup season kicks in.
It makes total sense after one bowl. You get everything people love about classic lasagna:
- Savory Italian sausage simmered in a garlicky tomato broth
- Tender broken lasagna noodles with those wavy, ruffled edges
- A cheesy ricotta topping mixed with mozzarella and Parmesan
- One pot to wash at the end of the night
It’s also on the table in under an hour. Baked lasagna usually eats up closer to two. I think the soup is even better than the baked version, but that’s just me.
Fun fact that surprised me: in Italian, “lasagna” means a single sheet of pasta. The baked dish is usually called “lasagne,” the plural. So a bowl with a few stray noodle pieces floating around is kind of the most literal version of the name.
What You’ll Need
Most of this is probably already hiding in your pantry. I split the list in two, since the cheesy topping gets mixed separately and goes on at the very end.
For the Soup
| Ingredient | Amount | Quick Note |
|---|---|---|
| Olive oil | 1 tablespoon | For browning the sausage |
| Italian sausage (mild or hot), casings removed | 1 pound | The flavor backbone of the pot |
| Yellow onion, diced | 1 medium | Adds a mellow sweetness |
| Garlic cloves, minced | 4 | Please don’t skimp here |
| Tomato paste | 2 tablespoons | Deepens the tomato flavor |
| Dried oregano | 1 teaspoon | That classic lasagna smell |
| Dried basil | 1 teaspoon | Plays nicely with tomato |
| Red pepper flakes | 1/2 teaspoon | Optional, for a little kick |
| Crushed tomatoes | 1 can (28 ounces) | Gives the broth its body |
| Low-sodium chicken broth | 6 cups | Lets you control the salt |
| Bay leaf | 1 | Pull it out before serving |
| Salt | 1/2 teaspoon, plus more to taste | The sausage is already salty |
| Black pepper | 1/2 teaspoon | Freshly ground if you have it |
| Granulated sugar | 1 teaspoon | Optional, softens sharp tomatoes |
| Lasagna noodles, broken into bite-size pieces | 8 ounces (about 9 to 10 noodles) | Regular, not no-boil |
| Fresh baby spinach | 2 cups | Optional, wilts in at the end |
For the Cheesy Topping
| Ingredient | Amount | Quick Note |
|---|---|---|
| Whole milk ricotta | 1 cup | The creamy base |
| Shredded mozzarella | 1 cup | For those stretchy cheese pulls |
| Grated Parmesan | 1/2 cup, plus extra for serving | Salty, nutty finish |
| Fresh parsley, chopped | 1 tablespoon | A little color and freshness |
| Salt and black pepper | A pinch of each | Just enough to wake it up |
| Fresh basil leaves | A small handful | For garnish |
Side Note: Ricotta literally means “recooked” in Italian. It’s traditionally made by reheating the leftover whey from cheesemaking, which is why it turns out so soft and fluffy.
Tools You’ll Want on the Counter
- Large Dutch oven or heavy soup pot (6 quarts or bigger)
- Wooden spoon
- Chef’s knife and cutting board
- Medium mixing bowl for the cheese topping
- Measuring cups and measuring spoons
- Can opener
- Box grater, if you’re grating your own Parmesan
- Large zip-top bag for breaking the noodles
- Ladle
No fancy gadgets here. If you own one big pot, you’re basically set.

Pro Tips Before You Start
- Break the noodles inside a bag. Toss them in a zip-top bag and snap them with your hands. I once broke them straight over the pot and spent five minutes picking pasta shards off the stovetop.
- Use regular lasagna noodles, not no-boil. No-boil sheets are thin and precooked, so they go soft and floppy way too fast in a simmering pot.
- Keep the simmer gentle once the noodles go in. A hard, rolling boil tears up their pretty ruffled edges.
- Never stir the ricotta into the pot. Spoon it on top of each bowl instead. Boiled ricotta can turn grainy, and you lose those creamy, cheesy bites.
- Season at the very end. Italian sausage and Parmesan both bring plenty of salt, so taste the broth after the noodles cook before adding more.
How to Make Cheesy Lasagna Soup Step by Step
| Prep Time | Cook Time | Total Time | Servings |
|---|---|---|---|
| 15 minutes | 40 minutes | 55 minutes | 6 bowls |
Step 1: Mix the Cheesy Topping First
In a medium bowl, stir together the ricotta, mozzarella, Parmesan, parsley, and a pinch of salt and pepper. Cover it and pop it in the fridge.
Doing this first means it’s waiting for you the second the soup is done. Hungry people don’t like waiting, and Silas is no exception.
Step 2: Brown the Sausage
Heat the olive oil in your Dutch oven over medium-high heat. Add the sausage and break it into small crumbles with a wooden spoon.
Cook for 6 to 8 minutes, until it’s browned with no pink left. If a lot of grease pools in the pot, spoon out all but about a tablespoon.
Step 3: Soften the Onion and Garlic
Turn the heat down to medium. Add the diced onion and cook for 4 to 5 minutes, stirring now and then, until it’s soft and see-through.
Stir in the garlic for just 30 seconds, until it smells amazing. Garlic burns fast and turns bitter, so stay close.
Step 4: Toast the Tomato Paste and Spices
Add the tomato paste, oregano, basil, and red pepper flakes. Stir and cook for about 2 minutes, until the paste darkens to a deep brick red.
This tiny step makes the broth taste like it bubbled away all afternoon.
Step 5: Build the Broth
Pour in the crushed tomatoes and chicken broth. Scrape the bottom of the pot to pull up all those browned bits, because that’s pure flavor.
Add the bay leaf, salt, pepper, and sugar. Bring it to a boil, then lower the heat and let it simmer for 15 minutes.
Step 6: Cook the Noodles
Bring the soup back to a steady simmer, bubbling but not raging. Add the broken noodles a handful at a time, stirring as you go so they don’t clump into one giant pasta brick.
Cook for 10 to 12 minutes, stirring often, until the noodles are tender with a little bite left. Check your package time too, since brands vary.
Step 7: Wilt the Spinach and Taste
Stir in the spinach for the last minute or two, just until it wilts. Fish out the bay leaf, turn off the heat, then taste and adjust the salt and pepper.
Step 8: Ladle and Top
Ladle the soup into bowls and drop a big spoonful of the cheesy topping right in the center. Finish with extra Parmesan and a few torn basil leaves.
Then watch the topping slowly melt into the broth. Silas calls this “the lasagna moment,” and honestly, he’s not wrong.

Time-Saving Tricks for Busy Weeknights
- Chop while the pot heats. Dice the onion while the oil warms up.
- Break the noodles during the simmer. That 15-minute window is plenty of time to bag and snap them.
- Grab pre-shredded mozzarella. It saves a few minutes and works fine in the topping.
- Keep jarred minced garlic around. Fresh tastes a little better, but on a hectic night it’s a lifesaver.
Substitutions and Variations
| Swap This | For This | Good to Know |
|---|---|---|
| Italian sausage | Ground beef or turkey plus 1/2 teaspoon fennel seed | Fennel brings back that sausage flavor |
| Lasagna noodles | Mafaldine or campanelle | Mafaldine looks like tiny lasagna ribbons |
| Crushed tomatoes | 1 jar (24 ounces) marinara | Cut the dried herbs in half |
| Chicken broth | Beef or vegetable broth | Beef broth tastes richer and darker |
| Ricotta | Cottage cheese, blended smooth | A bit tangier, with extra protein |
| Spinach | Chopped kale | Add it 5 minutes earlier, it’s tougher |
Fun Variations to Try
- Spicy lasagna soup: use hot Italian sausage and an extra pinch of pepper flakes.
- Veggie-loaded: add sliced mushrooms and diced zucchini along with the onion.
- White lasagna soup: swap the crushed tomatoes for extra broth and stir in a cup of heavy cream at the end.
- Beef and sausage combo: use half a pound of each for a heartier, meat-sauce feel.
Easy Swaps for Different Diets
- Gluten-free: use gluten-free lasagna noodles and check that your sausage and broth are labeled gluten-free. Cook these noodles separately, since they break down faster.
- Vegetarian: replace the sausage with 1 cup of cooked brown lentils and 8 ounces of mushrooms, and use vegetable broth. Real Parmigiano Reggiano is made with animal rennet, so pick a vegetarian hard cheese instead.
- Lighter: go with turkey sausage plus part-skim ricotta and mozzarella.
- Lower-carb: skip the noodles and add zucchini ribbons for the last 3 minutes.
Make-Ahead Tips
This soup is a meal-prep dream with one rule: keep the noodles out until dinner time.
- Make the soup base (everything except the noodles and spinach) up to 3 days ahead and store it in the fridge.
- Mix the cheesy topping up to 2 days ahead and keep it covered.
- When you’re hungry, bring the base to a simmer and cook the noodles right in it. Dinner lands in about 15 minutes.
Leftovers and Storage
Fair warning: those noodles keep drinking the broth overnight. Day-two lasagna soup comes out thicker, almost like a stew. (Silas prefers it that way. I do not.)
- Fridge: Store it in an airtight container for 3 to 4 days. Keep the cheesy topping in its own container.
- Reheat: Warm it on the stove over medium-low heat with a splash of broth or water to loosen it up again.
- Freezer: Freeze the soup base without noodles for up to 3 months. Thaw it overnight in the fridge, then cook fresh noodles in it.
- Skip freezing the topping: ricotta turns grainy once frozen, so mix a fresh batch instead.
Side Note: If you already know there’ll be leftovers, boil the noodles in a separate pot and add them to each bowl. The extra soup stays brothy that way.
Nutrition Snapshot Per Serving
Here’s a rough estimate for one bowl with the cheesy topping, based on 6 servings. Your numbers will shift a little depending on the sausage and cheese brands you use.
| Nutrient | Approximate Amount |
|---|---|
| Calories | About 600 |
| Protein | About 32 grams |
| Carbohydrates | About 45 grams |
| Fiber | About 4 grams |
| Fat | About 30 grams |
| Sodium | About 1,350 milligrams |
That’s a solid hit of protein for a cozy pasta dinner. And cooking tomatoes actually makes their lycopene easier for your body to absorb, so you’re sneaking in a little bonus nutrition too.
What to Serve With Lasagna Soup
- Garlic bread for dunking (non-negotiable in our house)
- Caesar salad for something crisp and cool
- Arugula salad with lemon, olive oil, and shaved Parmesan
- Warm focaccia or a crusty loaf
- Roasted broccoli with a squeeze of lemon
- A glass of Chianti if it’s that kind of night
FAQs Related to Cheesy Lasagna Soup
1. What is lasagna soup?
Lasagna soup is a one-pot soup with all the classic flavors of lasagna. Broken lasagna noodles simmer in a tomato broth with Italian sausage, garlic, and herbs, and each bowl gets a creamy ricotta, mozzarella, and Parmesan topping.
2. How do you keep lasagna soup noodles from getting mushy?
Cook them only until tender with a slight bite, and keep the simmer gentle. If you’re planning on leftovers, cook the noodles separately and add them to each bowl, since they keep soaking up broth as they sit.
3. Can I use no-boil lasagna noodles in soup?
You can, but they cook much faster and soften quickly. Add them at the very end and start checking them early. Regular noodles hold their shape a lot better.
4. Can you freeze lasagna soup?
Yes. Freeze the soup base without noodles for up to 3 months. Frozen noodles go mushy once thawed, so cook a fresh batch when you reheat.
5. Should you stir ricotta into lasagna soup?
Not into the whole pot. A dollop on each bowl stays creamy and gives you those cheesy, lasagna-like bites. Ricotta stirred into boiling soup can turn grainy.
6. How long does lasagna soup last in the fridge?
About 3 to 4 days in an airtight container. Add a splash of broth when you reheat it, because the noodles thicken things up overnight.
7. Can I make lasagna soup in a slow cooker?
Yes. Brown the sausage and onion on the stove first, then add everything except the noodles, spinach, and topping to the slow cooker. Cook on low for 6 to 7 hours, boil the noodles separately, and stir them in right before serving.
Conclusion
You don’t need a free Sunday afternoon to get real lasagna comfort. One pot, under an hour, and a bowl that tastes like you tried way harder than you actually did.
Make it this week while sweater weather is still here, and I have a feeling you’ll kind of wanna make it on repeat.
