This soup became a regular in my house during a stretch when I wanted dinner to feel a little more exciting without adding more work to my evenings. I had a bag of cheese tortellini in the freezer, some Italian sausage in the fridge, and a slow cooker that had mostly been reserved for chicken soups up to that point. Throwing them together turned into one of the easiest, most satisfying dinners I make — rich, savory, and ready by the time I get home, with barely any effort required once it’s in the pot.
This Crockpot Sausage Tortellini Soup combines savory Italian sausage, cheese tortellini, and spinach in a rich tomato-based broth, all cooked together in the slow cooker. It’s become one of my go-to hands-off dinners, right alongside chicken-based options like my Crockpot Chicken Noodle Soup and my Classic Homemade Chicken Noodle Soup, giving me a rotation of easy soups that all deliver a lot of comfort for very little active effort.
Why This Recipe Works
Browning the sausage before it goes into the slow cooker, rather than adding it raw, builds a deeper, more savory flavor into the broth from the start — the same principle behind browning chicken or beef before slow cooking any soup or stew. Letting the tomato-based broth simmer low and slow for several hours gives the flavors plenty of time to meld together, much like the long, gentle cooking time that makes a good chicken noodle soup taste so rich by the time it’s done.
Adding the tortellini toward the very end of cooking, rather than at the start, keeps the pasta from turning mushy or falling apart over hours in the slow cooker — the same care taken with noodles in a chicken noodle soup, where pasta is always best added close to serving time rather than left to sit in hot broth for too long.
Ingredients You’ll Need
- 1 lb Italian sausage (mild or spicy), casings removed if links
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 1 can (28 oz) crushed tomatoes
- 1 can (14.5 oz) diced tomatoes
- 5 cups chicken broth
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- ½ teaspoon red pepper flakes (optional)
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper
- 1 lb refrigerated or frozen cheese tortellini
- 3 cups fresh baby spinach
- Grated parmesan cheese, for serving
Step-by-Step Instructions
1. Brown the Sausage
In a skillet over medium heat, cook the Italian sausage, breaking it up as it browns, for 6–7 minutes, until no longer pink. Drain any excess fat.
2. Add the Base Ingredients
Transfer the browned sausage to the slow cooker along with the onion, garlic, crushed tomatoes, diced tomatoes, chicken broth, oregano, basil, red pepper flakes if using, salt, and pepper. Stir to combine.
3. Cook Low and Slow
Cover and cook on low for 6–7 hours, or on high for 3–4 hours, until the flavors have melded together.
4. Add the Tortellini and Spinach
Stir in the tortellini and cook on high for an additional 15–20 minutes, until the tortellini is tender. Add the spinach during the last few minutes, stirring until wilted.
5. Serve
Taste and adjust seasoning as needed. Ladle into bowls and top with grated parmesan before serving.
Tips From My Kitchen
- Don’t skip browning the sausage — it adds a lot of flavor to the finished broth.
- Add the tortellini toward the end of cooking to keep it from turning mushy.
- If making ahead, consider cooking the tortellini separately and adding it to individual bowls, since it’ll keep absorbing liquid otherwise.
- A splash of heavy cream stirred in at the end makes for a creamier variation if you’d like.

For a lighter version, use a lean turkey Italian sausage and a reduced-fat cheese tortellini — the soup will still be rich and satisfying, just with less overall fat.
Storage and Reheating
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop over low heat, adding extra broth as needed since the tortellini continues to absorb liquid as it sits. If freezing, it’s best to freeze the soup without the tortellini, then cook fresh tortellini and add it after reheating, since pasta can turn mushy after being frozen and thawed.
Frequently Asked Questions
Can I use frozen tortellini instead of refrigerated?
Yes, frozen tortellini works well and can be added directly to the slow cooker without thawing first — just add a few extra minutes to the cooking time if needed.
Can I make this vegetarian?
Yes, skip the sausage and use vegetable broth in place of chicken broth. Adding a can of white beans or sautéed mushrooms helps keep the heartiness of the original.
Can I make this on the stovetop instead of a slow cooker?
Yes, brown the sausage and simmer the broth mixture in a large pot for about 25–30 minutes, until the flavors meld, then add the tortellini and spinach during the last several minutes of cooking.
Can I freeze this soup?
It’s best to freeze the soup without the tortellini, since pasta can turn mushy when thawed. Freeze the base, then cook fresh tortellini and add it after reheating for the best texture.
Final Thoughts
This Crockpot Sausage Tortellini Soup has become one of my favorite ways to get a rich, restaurant-style dinner on the table with almost no active effort. It’s savory, hearty, and always a hit whenever I make a batch. I hope it becomes a regular in your slow cooker rotation too.
