Creamy Fresh Herbs Tortellini Soup
A rich, velvety sausage and butternut squash tortellini soup topped with a luxurious cheese swirl and fresh herbs.
- Roasting the squash concentrates its natural sugars through caramelization rather than diluting them in boiling broth.
- Blending half of the roasted squash creates a naturally thick, velvety base without requiring excessive heavy cream.
- The fresh ricotta and Parmesan cheese swirl adds a bright, creamy contrast that cuts through the savory richness of the Italian sausage.
I still remember the exact Tuesday night three winters ago when my cheap plastic immersion blender gave up the ghost, spraying half-pureed butternut squash all over my favorite cream-colored knit sweater.
It was a complete mess.
That flimsy blender failed every single test because its motor couldn't handle the thermal mass of hot squash.
I stood there scraping hot orange pulp off the cabinets with my fingernails, utterly defeated by my own dinner while my stomach growled in protest.
Think about this in terms of physics: boiling squash just waterlogs the vegetable, whereas roasting triggers the Maillard reaction, caramelizing those natural sugars before they ever touch a liquid, while also utilizing the starch gelatinization from the tortellini to naturally thicken the broth, unlike a thin Poblano Corn Chowder or a watery Creamy Golden Vegetable Soup.
Trust me on this one.
My simple fix is roasting the butternut squash alongside sweet Italian sausage, letting the rendered pork fat coat the squash flesh.
By the time you toss the tender squash into the pot with cheese tortellini and a quick, homemade cheese swirl topping, you have an absolutely perfect bowl of comfort that actually clings to your spoon, much like our favorite Broccoli Cheddar Soup.
Creamy tortellini soup in bowl with sausage, squash, herbs, and cheese swirl topping
Ingredients
- 1 medium butternut squash, peeled and cubed (about 4 cups)
- 1 lb sweet Italian sausage, casings removed
- 1 tbsp olive oil
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 4 cups low-sodium chicken broth
- 1 tbsp Diamond Crystal kosher salt
- 1/2 tsp freshly cracked black pepper
- 9 oz refrigerated cheese tortellini
- 2 cups fresh baby spinach
- 1/2 cup heavy cream
- 1/2 cup whole milk ricotta cheese
- 1/4 cup grated Parmesan cheese
- 1 tbsp fresh basil, finely chopped
Directions
- Preheat your oven to 400°F (204°C). On a large baking sheet, toss the cubed butternut squash with olive oil and a pinch of salt.
- Pinch the Italian sausage into bite-sized chunks with your hands and scatter them across the baking sheet with the squash. Roast for 25 minutes until the squash is tender and caramelized, and the sausage is golden brown.
- While roasting, heat a large Dutch oven over medium heat. Add the diced onion and sauté for 5 minutes until translucent, then stir in the minced garlic and cook for 1 minute until fragrant.
- Pour in the chicken broth, scraping up any browned bits from the bottom of the pot. Bring to a gentle simmer.
- Transfer half of the roasted squash to a blender with a splash of broth and puree until completely smooth. Pour the puree back into the Dutch oven to create a thick, creamy base.
- Add the remaining roasted squash, roasted sausage, and cheese tortellini to the pot. Simmer for 5 to 7 minutes until the tortellini is tender and cooked through.
- Stir in the baby spinach and heavy cream, cooking for 2 minutes until the spinach is wilted. Season with Diamond Crystal kosher salt and black pepper to taste.
- In a small bowl, whisk together the ricotta, Parmesan, chopped basil, and a drizzle of olive oil until smooth. Ladle the soup into bowls and top each with a generous swirl of the cheese mixture and fresh herbs. </
Notes
- We use Diamond Crystal kosher salt; if you are using Morton's kosher salt, reduce the volume by half to avoid over-salting your soup base.
- Pureeing half of the roasted squash releases starch and creates a natural emulsion with the chicken broth, giving you a velvety body without relying entirely on heavy cream.
- Keep a close eye on the garlic when sautéing in the Dutch oven; burnt garlic turns bitter instantly and will ruin the delicate sweetness of the squash.
- The tortellini will continue to absorb liquid as it sits in the fridge, turning the leftovers into a thick pasta dish. Store the pasta separately if you plan on making this ahead.
Serving Suggestions
Complete this cozy meal by serving it alongside warm, crusty bread to scoop up every last drop of the creamy broth and cheese swirl.
- A basket of warm Homemade Garlic Bread fresh from the oven.
- Soft, pull-apart Garlic Bread Rolls to dip directly into the cheese swirl.
- A crisp green salad tossed with a light lemon vinaigrette to cut through the richness of the soup.
- Extra grated Parmesan cheese and red pepper flakes on the side for guests to customize their bowls.
Storage and Reheating
Let's be honest about leftovers.
If you store the soup with the tortellini already in it, those little pasta pockets will act like sponges overnight, sucking up all your beautiful, velvety broth and leaving you with dry pasta.
To avoid this, boil the tortellini separately if you plan on having leftovers.
When reheating, warm the creamy squash broth on the stovetop over medium-low heat, stirring frequently to prevent the dairy from separating and losing its emulsion.
Gently drop the pasta back in just before serving.
Ingredient Substitutes
If you don't have everything on hand, don't panic—this recipe is incredibly forgiving and easy to adapt.
- Butternut Squash: You can easily swap this for sugar pumpkin or honeynut squash, which offer a similar sweet profile.
- Sweet Italian Sausage: Spicy Italian sausage works beautifully if you want a kick, or use chicken sausage for a lighter option.
- Cheese Tortellini: Gluten-free tortellini or even a sturdy pasta shape like rigatoni will work in a pinch.
- Baby Spinach: Kale makes a fantastic substitute; just chop it finely and let it simmer a few minutes longer to tenderize.
I hope this cozy bowl brings as much warmth to your kitchen table as it does to mine, minus the blender explosion, of course!
