Preheat your oven to 400°F (200°C). In a large bowl, toss the cubed butternut squash with olive oil, dried sage, dried thyme, ground nutmeg, salt, and pepper until well-coated. Spread the squash in a single layer on a baking sheet and roast for 20-25 minutes, or until the squash is tender and caramelized, with a beautiful golden hue.

In a large skillet, heat a drizzle of olive oil over medium heat. Add the crumbled beef sausage and cook, breaking it apart, until it's browned and cooked through, about 7-10 minutes. Remove the sausage from the skillet and set it aside, leaving the delicious drippings to enhance the subsequent steps.

In the same skillet, add diced yellow onion and sauté for 5-7 minutes until it becomes translucent and fragrant. Stir in minced garlic and cook for an additional minute, until aromatic. Then, pour in the vegetable broth to deglaze the pan, scraping up any brown bits, and allow it to simmer until reduced by half, about 2-3 minutes.

Add the roasted butternut squash to the skillet with the broth mixture. Simmer for 5 minutes, allowing the flavors to meld while stirring occasionally. Once done, remove from heat and carefully blend the mixture until smooth using an immersion blender or a regular blender, creating a creamy sauce ready to elevate your Hearty Butternut Squash Pasta.

Return the blended sauce to low heat and stir in heavy cream, allowing it to warm through for a couple of minutes. Taste and adjust the seasoning with additional salt and pepper as needed, keeping the sauce warmed without boiling it to maintain a rich, creamy texture.

In a large pot, bring salted water to a boil, then add farfalle pasta and cook according to package instructions until al dente, usually around 8-10 minutes. Remember to reserve 1 cup of pasta water before draining, which will help adjust the sauce’s consistency later on.

In the skillet with the creamy sauce, toss the drained pasta and cooked beef sausage together until well-coated. Stir in the fresh baby spinach and cook for 1-2 minutes until wilted, creating a vibrant and nutritious blend. Use some of the reserved pasta water to adjust the sauce texture if necessary.

Mix in grated Parmesan cheese and reserved roasted squash cubes for texture and flavor. Taste and adjust the seasoning if needed. Serve your Hearty Butternut Squash Pasta with Beef Sausage and Spinach hot, garnished with extra Parmesan, fresh parsley, and a sprinkle of red pepper flakes for a touch of heat!
