Tweaking Sausage, Spinach and Butternut Sauce Recipe for Dinner

I made the Pasta with Spicy Sausage, Baby Spinach and Creamy Butternut Sauce for dinner tonight.  I made a few alterations to the original recipe (changes highlighted below).  I thought this was a different way to have pasta and use a butternut squash.

• 11 oz (4 links) spicy chicken Italian sausage (I used 4 links of Italian Pork Sausage)
• 1 lb butternut squash, peeled and diced
• 1 tbsp light butter
• 10 oz casarecce, or pasta of your choice 
• 1/4 cup shallots, minced
• 3 cloves garlic, minced
• 2 cups baby spinach, roughly chopped
• 2 tbsp fresh shaved parmesan cheese (didn't have any so omitted)
• 4 sage leaves, sliced thin (sprinkle of ground sage)
• about 1/3 cup of milk
• kosher salt and freshly ground black pepper, to taste

Bring a large pot of salted water to a boil. Add butternut squash and cook until soft. (I will roast my squash, which is much easier)  Remove squash with a slotted spoon and place in a blender, blend until smooth. (I had roasted some butternuts the day before; after roasting I mashed the desired amount and refrigerated until tonight)

Add pasta to the boiling water and cook according to package directions for al dente, reserving at least 1 cup of the pasta water before draining.

Meanwhile, in a large deep non-stick skillet, sauté sausage over medium heat until browned, breaking up with a spoon as it cooks. When cooked through, set aside on a plate. (I baked the links once cooked I chopped up the sausage)

Reduce heat to medium-low and melt the butter, sauté the shallots and garlic until soft and golden, about 5 - 6 minutes. Add pureed butternut squash, season with with salt and fresh cracked pepper and add a little of the reserved pasta water (about 1 cup) to thin out the sauce to your liking. (I added regular tap water and some chicken bouliion; brought to a boil reduced heat added milk and simmered) Add baby spinach and stir in parmesan cheese and sage. Toss in cooked pasta and sausage and mix until well coated.
