Lasagna is my favorite dinner on the planet. Layering it is my least favorite kitchen job on the planet.
Boiling noodles, spreading ricotta, peeling apart sheets that glued themselves together… by the time the pan goes in the oven, I’m done. So this fall I stopped fighting it and turned the whole thing into a crockpot lasagna soup.
Same rich meat sauce. Same melty mozzarella. Same cool, creamy ricotta on top. You just skip the assembly and let your slow cooker do the heavy lifting while your kitchen starts smelling like an Italian nonna moved in.
Silas wandered in around hour four, lifted the lid “just to check,” and then did it again ten minutes later. I ended up moving the crockpot to the far counter.
That lid habit is one of the sneaky mistakes I’ll walk you through below. So is the noodle timing trick that keeps this soup from turning into a bowl of mush (a lot of recipes skip it, and you can tell).
Side Note: Here’s a fun fact for the dinner table. One popular theory says the word “lasagna” comes from an ancient Greek word for a pot stand, which could also mean a chamber pot. The Romans borrowed it as “lasanum,” their word for a cooking pot. So the dish is literally named after the pot. Maybe leave out the chamber pot part if the kids are listening.
Why This Slow Cooker Lasagna Soup Works
I’ve tested a lot of lasagna soups over the years. This version keeps winning, and here’s why.
- About 20 minutes of real work. You brown the meat, dump everything in, and walk away.
- Two kinds of meat. Ground beef brings the body, and Italian sausage sneaks in fennel, garlic, and spice with zero extra effort.
- The ricotta topping. This is what makes it taste like real lasagna instead of tomato soup with pasta floating around.
- It feeds a crowd. One batch serves 8, and the soup base freezes really well.
- Mostly pantry staples. Canned tomatoes, broth, and dried herbs carry a lot of the flavor here.
What You’ll Need
Nothing fancy, I promise. Half of this is probably sitting in your pantry right now.

Pro Tips for First Timers
These are the little lessons I learned the hard way, so you can skip that part.
1. Always Brown the Meat First
Raw ground meat in a crockpot cooks into one big gray clump, and you can’t drain off the grease. Browning it in a skillet fixes both problems and adds a deep, savory flavor you just can’t get any other way.
And never add the meat frozen. Food safety guides all agree on this one, since frozen meat sits too long in the danger zone while it thaws.
2. Hold the Noodles Until the End
This is the big one. Noodles added at the start soak up the broth and turn into soft paste by dinner.
Add them for the last 20 to 30 minutes on HIGH and they come out tender with a little bite.
3. Keep That Lid Closed
Every peek lets heat escape. Clemson Cooperative Extension says lifting the lid drops the temperature by 10 to 15°F, which slows everything down.
(Silas, if you’re reading this… this one’s for you.)
4. Toast the Tomato Paste
Stir the paste around the hot skillet for a minute or two until it turns a darker, brick red. That tiny step cooks off the tinny, canned taste.
5. Season Your Ricotta
Plain ricotta tastes like, well, not much. A pinch of salt and pepper plus parmesan and fresh basil turns it into the creamy little cloud that makes each spoonful taste like real lasagna.
How to Make Crockpot Lasagna Soup Step by Step
Step 1: Brown the Meat
Heat your skillet over medium high heat. Add the ground beef and Italian sausage, breaking them into small crumbles with a wooden spoon.
Cook for 7 to 8 minutes until no pink remains (160°F on a meat thermometer). Carefully spoon off the extra grease.
Step 2: Cook the Onion, Garlic, and Tomato Paste
Add the diced onion to the meat and cook for 4 to 5 minutes until soft. Stir in the garlic for about 30 seconds, just until it smells amazing.
Push everything to one side, add the tomato paste to the empty spot, and let it toast for 1 to 2 minutes before mixing it in.
Step 3: Load the Slow Cooker
Scrape the meat mixture into your crockpot. Add the crushed tomatoes, diced tomatoes, broth, Italian seasoning, basil, red pepper flakes, sugar, salt, pepper, and bay leaves.
Give it a good stir so nothing is hiding on the bottom.
Step 4: Let It Simmer
Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours. Then go live your life.
Step 5: Add the Noodles
Fish out the bay leaves. Break the lasagna noodles into roughly 2 inch pieces and stir them in, pressing them down under the liquid.
Switch to HIGH, cover, and cook for 20 to 30 minutes. Stir once halfway so they don’t stick together, and start tasting at the 20 minute mark.
Step 6: Make It Creamy (Optional)
Stir in the heavy cream and spinach. The spinach wilts in about 2 minutes.
Step 7: Mix the Ricotta Topping
While the noodles cook, stir together the ricotta, parmesan, chopped basil, salt, and pepper in a small bowl.
Step 8: Serve It Up
Ladle the soup into bowls. Top each one with a big spoonful of the ricotta mixture and a handful of mozzarella, then give it a minute to melt.
Taste before you dig in and add a pinch more salt if needed. Canned tomatoes and broth vary a lot from brand to brand.

Quick Look at Cooking Times
| Setting | Soup Base | Noodles (on HIGH) | Total Cook Time |
|---|---|---|---|
| LOW | 6 to 7 hours | 20 to 30 minutes | About 7 hours |
| HIGH | 3 to 4 hours | 20 to 30 minutes | About 4 hours |
Substitutions and Variations
This recipe is super forgiving. Here’s how to make it your own.
| Swap This | For This | Good to Know |
|---|---|---|
| Ground beef | Ground turkey or chicken | Add an extra 1/2 tsp Italian seasoning since it’s milder |
| Mild Italian sausage | Hot Italian sausage | Skip the red pepper flakes |
| Lasagna noodles | Mafalda, campanelle, or rotini | Mafalda looks like tiny lasagna noodles |
| Ricotta | Small curd cottage cheese | Blend it for a smoother texture and more protein |
| Chicken broth | Beef or vegetable broth | Beef broth makes it richer |
| Heavy cream | Half and half | Or leave it out for a brothier soup |
| Spinach | Chopped kale | Add it with the noodles so it has time to soften |
Side Note: Mafalda pasta was named after Princess Mafalda of Savoy. Pretty fancy upgrade for a Tuesday night soup.
Ingredient Swaps for Different Diets
- Gluten free: Use gluten free lasagna noodles and start checking them at 15 minutes, since they soften faster.
- Vegetarian: Skip the meat and use 1 lb chopped mushrooms plus a 15 oz can of drained lentils with vegetable broth. Look for a vegetarian parmesan too, because traditional Parmigiano Reggiano is made with animal rennet.
- Lower carb: Leave out the noodles and stir in sliced zucchini for the last 30 minutes.
- Dairy free: Skip the cream and use a dairy free ricotta and mozzarella style shreds.
Make Ahead Tips
- Prep the night before: Brown the meat with the onion, garlic, and tomato paste, then refrigerate it in a sealed container. In the morning, tip it into the crockpot with everything else.
- Mix the ricotta early: The topping keeps covered in the fridge for up to 2 days.
Leftovers and Storage
Lasagna soup leftovers are honestly a highlight of my week. Just know this going in: those noodles keep drinking the broth overnight.
- Fridge: Refrigerate in shallow airtight containers within 2 hours of cooking. It keeps for 3 to 4 days.
- Thirsty noodles: Store the noodles separately if you can. If not, splash in a little extra broth when you reheat.
- Freezer: Cook the soup through Step 4, cool it, and freeze it without noodles for 2 to 3 months. Future you will be so grateful. Thaw it overnight in the fridge and cook fresh noodles when you reheat.
- Reheating: Warm it on the stove or in the microwave until it’s steaming hot all the way through (165°F). Don’t reheat leftovers in the slow cooker, because it warms up too slowly.
- Ricotta: Add it fresh to each reheated bowl. Frozen ricotta turns grainy.
Nutrition Snapshot
Here’s a rough look per serving (1 of 8), with the ricotta topping and cream included. Your numbers will shift a little depending on the brands you use.

Want it lighter? Swap in ground turkey, skip the cream, and go with part skim cheeses. That trims a big chunk of the fat without losing the cozy factor.
What to Serve With Lasagna Soup
- Garlic bread for dunking (non negotiable at our house)
- Caesar salad or a simple arugula salad with lemon
- Roasted broccoli with a little shaved parmesan
- Warm focaccia brushed with olive oil
- A glass of Chianti for the grown ups, or sparkling water with lemon
Time Saving Tricks for Busy Weeknights
- Grab jarred minced garlic and frozen diced onion to cut your prep in half.
- Brown a few pounds of meat on Sunday and freeze it in 1 lb portions.
- No crockpot? Simmer everything in a Dutch oven for 30 minutes, then cook the noodles right in the pot for 10 to 12 minutes, stirring often.
