Pre-heat oven to 475°
Cut cauliflower into bite-sized florets. (Compost leaves and stem or save then for later to make homemade vegetable broth)
Place florets on a rimmed baking sheet and drizzle with 2 Tbsp olive oil. Sprinkle with garlic powder, salt and pepper and toss to combine.
Arrange florets in an even layer and roast for 15 minutes.
While florets are baking, combine butter, fresh garlic cloves and hot sauce in a small sauce pan. Melt ingredients together over medium low heat and set aside.
After 15 minutes remove cauliflower from the oven and toss with the melted butter and hot sauce mixture. Still very well to completely coat the cauliflower.
Roast in the oven for another 15 minutes until edges are crisp.
Serve hot out of the oven just as it is or with blue cheese dressing as a dip on the side.
