Sausage Tortellini Soup

This creamy sausage tortellini soup is your answer when you want a cozy, comforting dinner that doesn’t take forever. It’s a real weeknight hero — putting Italian sausage, tender tortellini, and fresh greens together in a luscious creamy broth. It comes together in about 30 minutes, so perfect if your evenings are packed.

The flavor layers here are so good: the savory sausage and cream make it filling, while just a touch of mustard powder and hot sauce add a subtle hint of depth you wouldn’t expect but can’t live without. If you’re after an even richer broth, try tossing in a Parmesan rind while the soup simmers — that trick really amps up the umami. Check out the Pro Tips later for that and more.

In this post, I’ve got the full ingredient list and a step-by-step guide for making this sausage tortellini soup on the stove in about half an hour. Plus, there’s a slow-cooker option if you want to set it and forget it, along with tips on storing leftovers (because who doesn’t love soup for days?). I like serving this with crusty garlic bread–it makes the meal even more satisfying!

Big Flavor, Minimal Fuss

This sausage tortellini soup hits all the right notes for a crowd-pleasing weeknight meal that’s quick and fuss-free. It’s creamy, filling, and all about big, comforting flavors. You get protein from the sausage, greens from kale or spinach, and pasta from the tortellini all in one bowl—no need for extra sides.

The secret? Just a small sprinkle of mustard powder and hot sauce adds a gentle flavor lift that’s easy to miss but makes a huge difference. Adding a Parmesan rind while it simmers is a fantastic way to make the broth extra rich and cozy. For another creamy, sausage-studded bowl with big Parmesan flavor, try Creamy Parmesan Italian Sausage Ditalini Soup.

Another bonus: this soup reheats beautifully and freezes well, especially if you cook or remove the tortellini before freezing to keep it from getting mushy. It’s super adaptable too — frozen or fresh tortellini, different greens, and you can even make it in a slow cooker if that fits your schedule better. Craving more pasta-in-soup comfort?

What You’ll Need

• 1 pound ground Italian sausage, hot or mild
• 1 small yellow onion, diced
• 3 cloves garlic, minced
• 3 Tablespoons flour
• 1 teaspoon dried basil
• ½ teaspoon oregano
• 1 pinch cayenne, optional
• 1 teaspoon hot sauce
• ½ teaspoon mustard powder
• ¼ teaspoon pepper
• 1 pinch red pepper flakes
• 1 cup heavy cream
• 5 cups chicken broth
• 2 cups kale, chopped
• 2 cups tortellini, just under 10 oz. (refrigerated or frozen)
• Salt/ to taste

Cook It in 30 Minutes

1. If using sausage links, remove the casings.
2. Heat a pan over medium-high and cook the sausage and diced onion, breaking up the meat, until onions soften and sausage is browned, about 8–10 minutes.
3. Drain off excess grease.
4. Add minced garlic and cook 1 minute until fragrant.
5. Sprinkle in the flour and cook, stirring, 1–2 minutes to remove the raw flour taste.
6. Add dried basil, oregano, cayenne (optional), hot sauce, mustard powder, black pepper, and red pepper flakes; stir to combine.
7. Pour in the chicken broth and scrape up any browned bits from the bottom of the pan, then slowly stir in the heavy cream; bring to a boil, then reduce heat and simmer.

8. Toss in the chopped kale and tortellini and simmer 3–5 minutes until the greens soften and the pasta is cooked (if tortellini needs more time, add it first and stir in the kale during the last 5 minutes).

   

9. Taste and season with salt to taste, starting with about 1/4 teaspoon and adjusting as needed.
10. For the slow-cooker method: brown the sausage and onions on the stovetop and add the flour as above.
11. Transfer the browned mixture (exclude the cream, tortellini, and greens) to the slow cooker.
12. Cook on high for 4–5 hours or low for 6–7 hours.
13. About 10–15 minutes before serving, stir in the kale to warm through.
14. Warm the cream (about 45 seconds in the microwave) to temper it, then slowly stir the cream into the slow cooker to avoid curdling.
15. Cook or reheat tortellini separately and add cooked tortellini to bowls, then ladle the soup over the tortellini if using the slow-cooker method.

Tips for Better Flavor and Texture

• If you want the broth to taste even richer, add a rind from Parmesan or Romano cheese when you add the broth and let it simmer gently to soak up that savory goodness. Just pull out the rind before serving. If you do this, there’s usually no need for extra salt.
• Swap kale for fresh spinach (2-3 cups) anytime. Stir it in after the tortellini is cooked and let it wilt super fast — like 30 seconds tops. If you’re using frozen spinach, thaw it fully and pat it dry before adding.
• Just a little fun fact: this recipe is featured in The Cozy Cookbook on page 51!
• When you want a change-up, check out my Sausage Gnocchi Soup—just as comforting but with a fun twist. And my Marry Me Chicken Soup is another family favorite that includes tortellini! If you’re craving more cozy bowls, try Chicken Pot Pie Soup or Stuffed Pepper Soup.

Ways to Customize It

• Switch up the sausage by using mild or hot Italian sausage, or for a leaner option, chicken or turkey Italian sausage. You can even make it vegetarian by using Italian-seasoned plant-based crumbles instead of meat.
• Try different greens like fresh spinach in place of kale — just stir it in at the end so it’s tender but still bright. Frozen spinach works too but be sure it’s thawed and patted dry.
• Mix up the pasta by swapping tortellini for gnocchi or cooked pasta you have on hand — a small shape like ditalini works especially well (see my creamy Parmesan Italian sausage ditalini soup). If you want leftovers that hold up well, cook the tortellini separately and add to bowls when serving to keep it from getting mushy.
• To lighten things up, swap the heavy cream for half-and-half or whole milk. For dairy-free, my favorite go-tos are full-fat canned coconut milk or cashew cream, just remember to use dairy-free pasta too.
• Add some extra cheesy love by stirring in shredded Parmesan or mozzarella right at the end. For a bit of extra nutrition and heartiness, toss in a can of white beans or sautéed mushrooms for a boost of umami — and if you love that combo, try my creamy chicken and mushroom soup.
• If you want to prep ahead, the slow cooker method is a dream: brown the sausage and onions first, then throw everything but the cream and tortellini in the slow cooker. Cook low and slow, add greens near the end, then temper and add cream before serving.

How to Store Leftovers

• Keep any leftovers in an airtight container in the fridge for up to 3 days or freeze portions for 3 months or longer. If you’re stocking the freezer, a simple broth-based option like Japanese Clear Soup freezes especially well.
• Because tortellini loves soaking up liquid, consider cooking it separately if you are saving soup for later. Add it to your bowl fresh when you’re ready to eat to keep things perfectly tender, not mushy.

Common Questions Answered

Q: Can I freeze this soup? A: Absolutely! Just freeze it without the tortellini to keep the best texture. Use airtight containers and it’ll stay good for about 3 months. When reheating, add a splash of broth if it’s gotten too thick.

Q: How long do leftovers last in the fridge? A: Store in airtight containers in the fridge for up to 3 days. Keep in mind tortellini absorbs broth and gets softer over time, so cooking the pasta separate is best for leftovers.

Q: Can I use frozen tortellini? A: Yes! Toss frozen tortellini straight into the simmering soup, just allow extra cooking time according to the package. If it needs quite a bit more time, add tortellini first, then add your greens toward the end.

Q: Is this soup dairy-free or gluten-free friendly? A: For dairy-free, swap cream for full-fat coconut milk or a nut cream and use dairy-free pasta. For gluten-free, use a gluten-free flour or cornstarch thickener and GF tortellini or another gluten-free pasta option.

Q: The tortellini gets mushy when I reheat leftovers — how can I avoid that? A: The best fix is to cook or reheat your tortellini separately, then add it fresh when serving. Alternatively, store soup and pasta separately before refrigerating or freezing.

Q: Do I need to take the casing off the sausage? A: Yes, if you have sausage links, pop off the casing and crumble the meat while cooking (as shown in this Italian sausage rigatoni recipe). If it’s already ground or bulk sausage, just crumble and cook as usual.
