Preheat your oven to 400°F (200°C).
Toss the cubed butternut squash with olive oil, salt, and pepper, then spread it on a baking sheet.
Roast the squash for 25-30 minutes, or until tender.
While the squash is roasting, heat a large skillet over medium heat and add the sausage.
Add minced garlic to the sausage and sauté until fragrant.
Pour in the vegetable broth and bring to a simmer.
Stir in the heavy cream and Parmesan cheese and cook until the cheese has melted.
Cook the gnocchi according to package instructions and drain.
Combine the roasted squash and gnocchi into the skillet with the sauce.
Garnish with fresh sage and serve immediately.
