Preheat your oven to 450 degrees.
Place butternut squash on a baking pan and roast for 45 minutes or until soft. Remove the seeds and skin.
Add the carrots to the pan 20 minutes after the squash has gone into the oven.
Chop the sweet onion and saute on medium heat in coconut oil.
Add all of the sauce ingredients to a high speed blender like a Vitamix and blend until smooth.
