Preheat oven to 400 F.
Clean head of cauliflower (if applicable).
Whisk remaining ingredients to create a sauce.
Place on a baking sheet (or in a baking dish if using a head). Cover the sheet with foil or parchment paper for an easier cleanup!
Coat cauliflower thoroughly with sauce.
If baking full head, cover with foil.
Cook for about half an hour, or when florets have become golden brown in the sauce (about one hour, or until it can be cut easily with a knife, for a head)
(Optional step for a head of cauliflower) If desired, remove foil and cook for another 5-10 minutes, so outside becomes golden brown.
Serve, and enjoy!
