Butternut Squash and Italian Sausage Soup

When the air turns crisp and the leaves begin to fall, few dishes feel more comforting than Butternut Squash and Italian Sausage Soup. This rich, creamy soup blends the nutty sweetness of roasted squash with the bold, savory taste of Italian sausage for the ultimate cold-weather comfort food. Perfect as a weeknight dinner or the centerpiece of a cozy fall gathering, this satisfying soup is guaranteed to warm both the heart and the home.

Ingredients You’ll Need
- 2 tablespoons vegetable oil
- 1 large onion, chopped
- 6 cloves garlic, minced
- 1½ to 2 pounds sweet Italian sausage, removed from casings
- 1 teaspoon salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon ground sage
- 1 teaspoon dried thyme
- 1 large butternut squash (about 3 pounds), peeled, seeded, and sliced
- 2 bay leaves
- 6 cups chicken stock or broth
- 2 tablespoons balsamic vinegar
- ½ cup heavy cream (or more as needed)
Step-by-Step Instructions
1. Sauté the aromatics.
In a large pot or Dutch oven, heat vegetable oil over medium heat. Add the chopped onion and garlic. Stir often until the mixture softens and starts to caramelize, about 5 minutes. This step builds a deep, flavorful base.
2. Brown the sausage.
Add sweet Italian sausage to the pot, breaking it apart with a wooden spoon. Season with salt and pepper. Cook until browned and fragrant, letting the rendered fat mingle with the onions and garlic.
3. Add herbs and squash.
Sprinkle in ground sage and dried thyme. Stir for about 1 minute to toast the herbs and release their aroma. Add sliced butternut squash and bay leaves.
4. Simmer to perfection.
Pour in the chicken stock and balsamic vinegar. Bring to a boil, then reduce the heat to low. Let it simmer for 30 minutes, stirring occasionally, until the squash is tender.
5. Blend and finish.
Remove the bay leaves. Blend the soup using an immersion blender until it reaches your desired texture—smooth or slightly chunky. Stir in heavy cream for a silky finish. Taste and adjust seasoning.
6. Serve.
Ladle the soup into bowls. Drizzle with a touch of cream or olive oil and serve with crusty bread.
Tips for Success
- For a deeper flavor, roast the butternut squash before adding it to the pot.
- If you prefer a lighter version, substitute half-and-half or coconut milk for heavy cream.
- Spice lovers can swap sweet Italian sausage for hot sausage to add a little kick.
- Garnish with fresh thyme, grated Parmesan, or toasted pepitas for extra texture.
This easy butternut squash and sausage soup is endlessly adaptable—make it creamy, chunky, spicy, or vegetarian with simple ingredient swaps.

Frequently Asked Questions
Can I use chicken sausage instead of Italian sausage?
Yes, chicken or turkey sausage works perfectly if you’re looking for a leaner option. The flavor will be a bit lighter but still delicious.
Can I use frozen butternut squash?
Absolutely. Frozen pre-cut squash is a time saver. It cooks a bit faster, so start checking tenderness around the 20-minute mark.
Do I have to blend the soup?
No. For a rustic texture, use a potato masher instead of a blender to leave small chunks of squash and sausage in the broth.
What can I use instead of cream?
Coconut milk or cashew cream are great dairy-free alternatives that keep the soup creamy and flavorful.
Can I make this in a slow cooker?
Yes. Brown the sausage first, then add all ingredients (except the cream) to the slow cooker. Cook on low for 6–8 hours, then stir in cream just before serving.
This Butternut Squash and Italian Sausage Soup embodies everything cozy cooking should be—comforting, nourishing, and irresistibly flavorful. Whether you’re looking for a quick weeknight dinner, a meal-prep winner, or a crowd-pleasing centerpiece for fall gatherings, this is the soup that never fails to impress.
