Begin by preparing your ingredients for the Cozy Autumn Sausage Pasta with Butternut Squash. Chop the butternut squash into small, even cubes, mince the garlic, and finely chop the onion. Grate the Parmesan cheese if needed, and keep it aside.

In a large skillet, heat a few tablespoons of olive oil over medium heat. Crumble the Italian sausage into the skillet, cooking for about 5 to 7 minutes until browned and cooked through.

Once the sausage is browned, stir in the chopped onion and minced garlic. Sauté for 3 to 4 minutes until the onion becomes translucent and soft.

Add the cubed butternut squash to the skillet, along with salt and pepper to taste. Cover and let cook for about 10 minutes, stirring occasionally.

While the vegetables are cooking, bring a large pot of salted water to a boil and cook your pasta according to package instructions, typically around 8 to 10 minutes.

Once drained, add the pasta directly to the skillet with the sausage and squash mixture. Pour in the heavy cream, stirring together. If thick, gradually mix in reserved pasta water.

Remove from heat and fold in fresh spinach, allowing it to wilt slightly. Serve topped with freshly grated Parmesan cheese.
