Preheat the oven to 400 degrees Fahrenheit.
Line a pan with parchment paper and place the chopped butternut squash on it. Mix it with rosemary and olive oil.
Make space in the middle of the pan to place the bulb of garlic.
Before placing it on the pan, cut the top of the bulb off, exposing the cloves and leaving the root (the 'hairy' or stringy part in tact). Remove the extra pieces of skin off the bulb, leaving enough on so that the cloves don't fall off the bulb.
Put some olive oil on the garlic, wrap in a small piece of aluminum foil and place in the center of the roasting pan.
Roast in the oven for about 30 minutes, until the squash is tender.
While that's cooking, in a pot bring the broth, vodka and cashews to a light boil. Cover and cook for about 15 minutes.
When the cashews, squash and garlic are finished cooking, let cool down just a bit before placing in the blender.
Make sure to squeeze the mushy garlic clove pieces out from the bulb and discard the skins. You don't want the skins in the blender.
Then place the lemon juice and remaining spices in the blender and blend until it's smooth and creamy. This could take a minute or two depending on your blender.
Pour over the pasta noodles and mix well.
Optionally, top with parsley and dairy-free parmesan cheese.
Enjoy!
