Why It’s a Weeknight Winner

This sausage tortellini soup is a total weeknight winner because it’s fast, filling, and uses ingredients you probably already have—much like Italian Sausage Pasta (a 30-minute meal). With protein from the Italian sausage, greens like kale or spinach for a veggie boost, and tender pasta all in one bowl, it’s a complete, comforting meal without any hassle. The little bursts of mustard powder and hot sauce round out the flavors without turning up the heat, and if you add a cheese rind while it simmers, you get delicious depth that might make extra salt unnecessary. Plus, it’s super flexible—you can make it on the stove or slow cooker, and it freezes beautifully if you keep the tortellini separate. Craving a creamier spin? Try Ang’s Creamy Tortellini Soup.

Ingredients and Measurements

• 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

Step-by-Step Cooking Directions

1. Remove casings from sausage links, if using.
2. Cook and crumble the sausage with diced onion over medium-high heat until onions are soft and sausage is cooked through (about 8–10 minutes); drain excess grease.
3. Add minced garlic and cook for 1 minute.
4. Sprinkle in the flour and stir 1–2 minutes to remove raw flour flavor.
5. Add dried basil, oregano, cayenne (if using), hot sauce, mustard powder, pepper, and red pepper flakes; mix to combine.

6. Pour in the chicken broth, scrape up any browned bits from the pot, and slowly stir in the heavy cream; bring to a boil, then reduce to a gentle simmer.

   

7. Optional: toss a Parmesan or Romano rind into the simmering broth for extra flavor, and remove the rind before serving.
8. Add chopped kale and tortellini and simmer 3–5 minutes until the pasta is cooked through (if tortellini needs longer, add it first and stir in kale during the last 5 minutes).
9. Taste the soup and add salt as needed, starting with 1/4 teaspoon and adjusting to taste.
10. Ladle the soup into bowls and serve warm.
11. For the slow cooker method: brown the sausage and onions on the stove and stir in the flour as directed above.
12. Transfer everything except the cream, tortellini, and kale into the slow cooker.
13. Cook on high for 4–5 hours or low for 6–7 hours.
14. Add the kale toward the end of cooking and let it cook 10–15 minutes until wilted.
15. Turn the slow cooker off, warm the cream briefly, stir it in slowly, then place cooked tortellini in bowls and ladle the soup over.

Flavor-Boosting Tips and Notes

• For a deeper flavor, toss a Parmesan or Romano cheese rind into the broth as it simmers. It adds a lovely cheesy richness. Remove the rind before serving. This may make extra salt unnecessary.
• Swap kale for 2-3 cups fresh spinach if you prefer. Stir it in after the tortellini cooks and let it wilt for about 30 seconds. For frozen spinach, thaw and squeeze out excess water before adding. For another cozy, spinach-studded option, try Olive Garden Chicken Gnocchi Soup.

Easy Swaps and Add-Ins

• Greens swap: Use 2–3 cups of baby spinach instead of kale; add it at the end and stir until wilted (or use thawed, well-drained frozen spinach).
• Pasta swap: Try tender gnocchi or small pasta shells in place of tortellini, adjusting cook times as needed (for gnocchi timing, see Chicken and Gnocchi Soup).
• Protein options: You can use hot or mild Italian sausage, ground turkey or chicken sausage, or a plant-based sausage for a vegetarian-friendly twist (just use veggie broth if you do!).
• Dairy adjustments: For a lighter soup, substitute half-and-half or whole milk; for dairy-free, full-fat coconut milk works well — thicken with cornstarch slurry if needed (for an example of a rich, dairy-free base, see this Creamy Vegan Asparagus Soup (Dairy Free)).
• Veggie boost: Add diced carrots, sliced mushrooms, or bell peppers when cooking the onions for extra color and nutrients.
• Spice it up or tone it down: Adjust cayenne, red pepper flakes, and hot sauce based on your heat tolerance.
• Slow cooker: Follow the crock pot instructions above — cook sausage and onions first, then transfer, adding cream and tortellini near the end — similar to how noodles are added in Crock-Pot Chicken Noodle Soup.

Storage, Freezing, and Reheating

• Keep the soup airtight in the fridge for up to 3 days or freeze it for 3 months or longer.
• Because tortellini soaks up broth over time, it’s best to cook it separately if you plan on saving leftovers (this same trick helps keep noodles al dente in Homemade Chicken Noodle Soup). Add it freshly when reheating for the best texture and flavor.

Answers to Common Questions

• Can I use frozen tortellini? Absolutely! Just follow the package instructions. If it needs more cooking time, add the tortellini earlier, and stir in kale during the last few minutes so it stays nice and fresh.
• Can I make this ahead or freeze it? Yes. Store in an airtight container in the fridge for up to 3 days, or freeze for 3+ months. For best results, cook or keep the tortellini separate and add it fresh to bowls at serving time.
• How do I reheat leftovers? Gently warm on the stove over low to medium heat or use a microwave. Add a splash of broth or water if the soup has thickened or the tortellini absorbed too much liquid.
• Can I use different sausage types? For sure! Mild or hot Italian sausage, turkey sausage, or plant-based sausage all work great. Just adjust seasoning if you swap to leaner meats.
• What if I don’t have heavy cream? Half-and-half or whole milk can be used for a lighter finish. For a dairy-free option, full-fat coconut milk is a good choice—add a cornstarch slurry if you want it thicker. When adding cream, warm it briefly first to avoid curdling, especially in a slow cooker.
• How do I thicken the soup more? This soup thickens with flour, but you can simmer uncovered to reduce it, whisk in a bit more flour mixed with cold water, or add a cornstarch slurry (1 tablespoon cornstarch + 1 tablespoon cold water) and cook until thickened—if you want a step-by-step example of using a slurry, see our Creamy Potato Soup.
• Is it salty? If you add a Parmesan or Romano rind to the simmering soup, you might not need extra salt. Always taste and add salt a little at a time, starting with ¼ teaspoon.
