Making Autumn Sausage Pasta Squash is straightforward and rewarding. Follow these steps to create this delightful dish:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Squash: Toss the cubed butternut squash with olive oil, salt, and pepper. Spread evenly on a baking sheet.
3. Roast the Squash: Bake in the preheated oven for 20-25 minutes or until tender and golden, stirring halfway through.
4. Cook the Pasta: Meanwhile, cook the pasta according to package instructions until al dente. Drain and set aside.
5. Brown the Sausage: In a large skillet over medium heat, add the Italian sausage. Cook until browned and crumbled, about 5-7 minutes. Remove excess fat if necessary.
6. Sauté the Aromatics: Add the diced onion and minced garlic to the skillet with the sausage. Sauté until the onion is translucent, about 3-4 minutes.
7. Add Herbs and Spices: Stir in the dried thyme, rosemary, and red pepper flakes (if using). Cook for an additional minute to release the aromas.
8. Combine Ingredients: Pour in the vegetable broth and heavy cream. Bring to a simmer and let it cook for 5 minutes.
9. Add Cheese: Stir in the grated Parmesan cheese until melted and well combined. Season with salt and pepper to taste.
10. Combine with Pasta: Add the cooked pasta and roasted squash to the skillet. Toss everything together until evenly coated.
11. Garnish and Serve: Remove from heat and garnish with fresh parsley before serving.
