Lasagna is one of my all-time favorite dinners, and it’s also the one I make the least. Boil the noodles. Make the sauce. Layer everything just right. Bake it for an hour, then wait again so it doesn’t slide all over the plate. By the time it’s done, I’ve usually eaten half the mozzarella straight out of the bag.
So the first time I made lasagna soup on a cold night in a tiny rental kitchen (two burners, one decent pot, zero patience), I was honestly kind of shocked. It tasted like lasagna. Like, real lasagna.
Silas went back for thirds and asked if we could have it again the next night. Coming from him, that’s basically a five-star review.
This spinach lasagna soup is the version I’ve made on repeat ever since. Savory Italian sausage, a garlicky tomato broth, tender noodles, and a big pile of spinach that melts right in.
There’s also one tiny step at the very end that turns every spoonful into the corner piece of a lasagna. You know, the bubbly, golden one everybody secretly fights over. I’ll show you exactly how in the steps below.
What Is Spinach Lasagna Soup?
Spinach lasagna soup is a one-pot soup made with Italian sausage, crushed tomatoes, garlic, Italian herbs, broken lasagna noodles, and fresh baby spinach. Each bowl gets a scoop of creamy ricotta and melty mozzarella on top, so it tastes just like classic baked lasagna. It’s on the table in about 50 minutes.

Why This Lasagna Soup Is My Go-To Fall Dinner in 2026
I’ve tested a lot of soups this year. This one keeps winning, and here’s why.
- One pot, one spoon. The noodles cook right in the broth, so there’s no extra pot of pasta water boiling over while you’re not looking.
- Way faster than real lasagna. No layering, no hour-long bake, and you still get all that rich, cheesy flavor.
- Sneaky greens. A full 5-ounce container of baby spinach goes in, and it shrinks down so much that even picky eaters barely notice.
- Mostly pantry staples. Canned tomatoes, broth, dried herbs, and a box of noodles. You probably have half of it already.
Side Note: Here’s a weird little fact for your next dinner party. According to Merriam-Webster, the word “lasagna” traces back to a Latin word for a chamber pot. Thankfully, the meaning shifted to “cooking pot” long before it reached our dinner tables.

What You’ll Need
Nothing fancy here. Every ingredient below is easy to find at a regular grocery store.
For the Soup
| Ingredient | Amount | Notes |
|---|---|---|
| Olive oil | 1 tablespoon | For browning the sausage |
| Mild Italian sausage, casings removed | 1 pound | Use hot sausage if you like a kick |
| Yellow onion, diced | 1 medium | About 1 cup |
| Garlic cloves, minced | 4 cloves | Fresh tastes best here |
| Tomato paste | 3 tablespoons | Gives the broth that deep, baked flavor |
| Dried oregano | 1 teaspoon | The classic lasagna herb |
| Dried basil | 1 teaspoon | Dried works great in the broth |
| Red pepper flakes | 1/4 teaspoon | Optional |
| Crushed tomatoes | 1 can (28 ounces) | Any brand works |
| Low-sodium chicken broth | 5 cups | Keeps the salt in check |
| Bay leaf | 1 | Remove before serving |
| Lasagna noodles | 10 noodles (about 8 ounces) | Broken into 2-inch pieces |
| Baby spinach | 5 ounces (about 5 packed cups) | Pre-washed saves time |
| Heavy cream | 1/2 cup | Optional, for a creamier broth |
| Salt and black pepper | To taste | Season at the very end |
For the Cheesy Ricotta Topping
| Ingredient | Amount | Notes |
|---|---|---|
| Whole milk ricotta | 1 cup | Creamier than part-skim |
| Grated Parmesan | 1/2 cup | Plus a little extra for serving |
| Shredded mozzarella | 1 cup | Low-moisture melts best |
| Fresh basil, chopped | 2 tablespoons | Save a few whole leaves for garnish |
| Salt and black pepper | A pinch each | For the ricotta mix |
Tools You’ll Need
- Large Dutch oven or heavy soup pot (6-quart or bigger)
- Wooden spoon for breaking up the sausage
- Cutting board and chef’s knife
- Measuring cups and spoons
- Can opener
- Small mixing bowl for the ricotta topping
- Ladle
- Oven-safe soup bowls and a baking sheet (optional, for the broiler finish)
Pro Tips Before You Start
I learned most of these the hard way, so you don’t have to.
- Let the sausage actually brown. Spread it out and leave it alone for 2 to 3 minutes before stirring. Those crispy brown bits stuck to the pot are pure flavor.
- Cook the tomato paste until it turns brick red. A minute or two in the hot pot takes away that tinny, canned taste and makes the broth taste like it simmered all afternoon.
- Stir the noodles a lot early on. Lasagna noodles love to clump together in the first few minutes. A good stir every couple of minutes keeps them from gluing themselves to the bottom.
- Turn off the heat while the noodles still have a little bite. They keep cooking in the hot broth, so slightly firm now means perfect five minutes later.
- Planning on leftovers? Cook the noodles separately. Pasta keeps soaking up broth in the fridge. Stored apart, your day-two soup stays soupy instead of turning into a casserole.
How to Make Spinach Lasagna Soup
The whole thing comes together in one pot. Here’s the step-by-step.
- Mix the ricotta topping. In a small bowl, stir together the ricotta, Parmesan, chopped basil, and a pinch of salt and pepper. Pop it in the fridge. Doing this first means your hands are free once the soup gets going.
- 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 browned with no pink left. If there’s a lot of grease, spoon off all but about 1 tablespoon.
- Soften the onion and garlic. Add the diced onion and cook for 4 to 5 minutes, until soft and see-through. Stir in the garlic and cook for 30 seconds, just until it smells amazing.
- Toast the tomato paste and herbs. Add the tomato paste, oregano, basil, and red pepper flakes. Stir constantly for 1 to 2 minutes, until the paste darkens and coats everything.
- Build the broth. Pour in the crushed tomatoes and chicken broth, then add the bay leaf. Scrape up all those browned bits from the bottom. Bring it to a boil, lower the heat, and simmer for 10 minutes.
- Cook the noodles. Bring the soup back to a gentle boil and drop in the broken noodles. Stir well. Simmer uncovered for 10 to 12 minutes, stirring often, until the noodles are tender but still a little firm.
- Add the spinach and cream. Fish out the bay leaf. Stir in the spinach a handful at a time until it wilts, about 1 to 2 minutes. Pour in the heavy cream if you’re using it, then taste and season with salt and pepper.
- Top it like lasagna. Ladle the soup into bowls. Add a big spoonful of the ricotta mixture, sprinkle mozzarella over the top, and finish with fresh basil and extra Parmesan.
Now for that little step I promised. Ladle the soup into oven-safe bowls, set them on a baking sheet, add the ricotta and mozzarella, and slide them under the broiler for 2 to 3 minutes.
The cheese bubbles up and gets golden, crispy edges, exactly like the corner of a lasagna pan. Watch it closely, because broilers go from golden to burnt fast. And grab those bowls with oven mitts. They get really hot.

Substitutions and Variations
This soup is super forgiving. Here are the swaps that work well.
| Instead of | Try | Good to Know |
|---|---|---|
| Italian sausage | Ground beef, ground turkey, or chicken Italian sausage | Add 1/2 teaspoon fennel seed to plain ground meat for that sausage flavor |
| Lasagna noodles | Mafalda, campanelle, or bowtie pasta | Mafalda looks like tiny lasagna noodles |
| Fresh spinach | Frozen chopped spinach | Use about 4 ounces, thawed and squeezed dry |
| Spinach | Chopped kale | Add it with the noodles so it has time to soften |
| Heavy cream | Half-and-half, or skip it | Skipping it keeps the broth bright and tomato-forward |
| Ricotta | Small-curd cottage cheese | Blend it for a few seconds for a smoother texture |
| Crushed tomatoes | Your favorite marinara | Taste before salting, since jarred sauce is often salty |
Easy Swaps for Different Diets
- Vegetarian: Skip the sausage and brown 8 ounces of sliced mushrooms instead, then use vegetable broth. Traditional Parmesan is made with animal rennet, so grab a vegetarian Parmesan-style cheese if that matters to you.
- Gluten-free: Use gluten-free lasagna noodles and check your sausage and broth labels, since some brands sneak in gluten. GF noodles soften faster, so start testing them a few minutes early.
- Dairy-free: Leave out the cream and cheeses. A spoonful of dairy-free ricotta or a sprinkle of nutritional yeast still gives you that cheesy finish.
- Lighter bowl: Use chicken or turkey Italian sausage, skip the cream, and go with part-skim ricotta.
Make-Ahead Tips
This soup is a meal prep dream if you plan it right.
- Make the base up to 2 days early. Cook everything through Step 5, let it cool, and refrigerate. At dinnertime, bring it back to a boil and pick up at Step 6 with the noodles.
- Mix the ricotta topping the night before. Covered tightly, it keeps in the fridge for up to 2 days.
- Get the chopping out of the way. Dice the onion, mince the garlic, and break the noodles ahead of time. Keep them in separate containers so dinner is mostly dump-and-stir.
Time-Saving Tricks for Busy Weeknights
- Chop the onion while the sausage browns instead of before.
- Break the noodles while the broth comes to a boil.
- Use jarred minced garlic in a pinch. About 1/2 teaspoon equals one clove.
Leftovers and Storage
Fair warning: this soup gets thicker overnight. The noodles keep drinking up the broth, so day-two soup is closer to a saucy pasta.
Silas actually prefers it that way. I like mine soupy, so I just add a splash of broth.
| Storage Method | How Long | Tips |
|---|---|---|
| Fridge | 3 to 4 days | Use an airtight container and store the ricotta topping separately |
| Freezer | Up to 3 months | Freeze it before adding the noodles, cream, and cheese |
- Stovetop reheating: Warm it over medium-low heat with a splash of broth or water to loosen it back up.
- Microwave reheating: Heat in 1-minute bursts, stirring in between, so it warms evenly.
- Thawing: Move frozen soup to the fridge the night before. Bring it to a boil and cook fresh noodles right in the pot.
Nutrition Snapshot
Here’s a rough estimate for one serving (1/6 of the pot) with the ricotta topping and no heavy cream. Brands vary a lot, so treat these as ballpark numbers.
| Nutrient | Per Serving (approx.) |
|---|---|
| Calories | 570 |
| Protein | 32 g |
| Carbohydrates | 43 g |
| Fat | 30 g |
| Fiber | 4 g |
| Sodium | 1,100 mg |
Adding the 1/2 cup of heavy cream bumps each bowl up by roughly 65 calories and 7 grams of fat. That’s a pretty solid amount of protein for a soup, thanks to the sausage and all three cheeses.
What to Serve With Lasagna Soup
- Garlic bread for dunking (non-negotiable in our house)
- A simple Caesar salad or arugula tossed with lemon and olive oil to cut through the richness
- Warm focaccia or crusty Italian bread
- Roasted broccoli with a pinch of red pepper flakes
- A glass of Chianti if you’re turning it into a cozy date night
FAQs Related to Spinach Lasagna Soup
1. Can you freeze lasagna soup?
Yes. Freeze the soup base without the noodles, cream, or cheese for up to 3 months. Noodles turn mushy in the freezer, so cook a fresh batch when you reheat.
2. Do you have to cook lasagna noodles before adding them to soup?
No. Break the dry noodles into pieces and cook them right in the simmering broth for 10 to 12 minutes. Only cook them separately if you’re planning on leftovers.
3. Can I make lasagna soup in a slow cooker?
Yes. Brown the sausage, onion, garlic, and tomato paste on the stove first. Add everything except the noodles, spinach, and cream to the slow cooker and cook on low for 6 to 7 hours or high for 3 to 4 hours. Stir in the noodles for the last 30 minutes on high, then add the spinach and cream right before serving.
4. Can I use no-boil lasagna noodles?
You can. No-boil noodles are thinner, so they cook much faster. Start checking them after about 5 minutes.
5. Is spinach lasagna soup healthy?
It’s a balanced comfort meal with protein from the sausage and cheese, plus fiber and vitamins from the tomatoes and spinach. The lighter swaps above trim it down even more.
Wrapping Up
This spinach lasagna soup gives you everything you love about lasagna without the layering, the long bake, or the sink full of dishes. Just one pot, a few easy steps, and a bowl of cheesy comfort that tastes like you worked way harder than you did.
Make it on the next chilly night. And try the broiler trick at least once, because those golden cheese edges are seriously addictive.
