Use a vegetable peeler to carefully peel the skin off the butternut squash. Trust me, peeling it is easier and you keep more of your squash!
Preheat your oven to 350 degrees and then spray a baking sheet, that has a piece of aluminum foil, with non-stick spray. Set aside.
Cut both ends off of the squashes.
Then, slice the Butternut Squashes so they are like burger patties.
Use a spoon to remove any seeds from the bottom of the squash and lay the slices on the prepared baking sheet.
Cut off both ends and remove the skin of the onion, then, slice the onion any which way you desire.
Lay them on the baking sheet around the Butternut Squash pieces.
Cut the top off the garlic head, then place it on the baking sheet.
Roast the vegetables
Bake the butternut squash and onions for 45 minutes, or until golden and roasted.
Remove the baking sheet from the oven with the roasted vegetables.
Place all of the garlic, onion and Butternut Squash pieces into a 6-Quart pan, then using a potato smasher, mash the large chunks into smaller ones.
Add water to the 6-Quart pot to fill just 2-inches below the rim.
Using an Immersion Blender, blend the soup until it is completely smooth. The amount of time this step takes depends upon the size of the Butternut Squash pieces.
Add 1 tsp nutmeg, salt and pepper and then mix well into the soup.
Simmer the Butternut Squash Soup
Bring the Butternut Squash Soup to a simmer and then cook for 30 minutes.
Serve with a salad, grilled cheese, a tasty bread or whichever side you desire and enjoy!
