Place cauliflower and garlic in a microwave steamer and using steam setting, cook on automatic until cauliflower is fork tender. About 8 -10 minutes.
While cauliflower and garlic is steaming, melt butter in a medium sized saucepan over low heat. Cook butter until it becomes foamy and begins to brown. Swirl pan often to mix butter.
When you see the brown solids forming in the bottom of the pan, remove from heat and set aside.
Swirl the butter again and remove one tablespoon to use as a drizzle over top of the cauliflower in the serving bowl.
When cauliflower and garlic is done steaming, place it in a food processor with salt, pepper, and all the butter except the reserved tablespoon.
Process cauliflower mixture until smooth. Taste to be sure it does not need more salt and adjust if needed.
Spoon garlic mashed cauliflower in a serving bowl. Drizzle with reserved butter and top with snipped chives.
Notes
Net Carbs per serving = 3
My garlic cloves were very large. I recommend doubling the amount of garlic if your cloves are smaller.
