Throw all of the ingredients into a high-speed blender, and blend until smooth and creamy.
Adjust seasonings to taste, then transfer to bowl and store in the fridge until ready to serve. The cheese sauce will thicken up when chilled, so I recommend chilling the sauce at least an hour or two before serving.
Serve with your favorite raw veggies, or chips, and enjoy!
Notes
This recipe makes a LOT of sauce, so feel free to make a half-batch if you're not hosting a party, or have a smaller family to cater to. (Or freeze the extras to enjoy for later!)
