Add the cauliflower to a large pot with a steamer basket. Add 2" of water and cover. Turn to high and steam the cauliflower until tender, about 5 minutes.
While the cauliflower is steaming, saute the garlic in the oil over medium heat, until the garlic is fragrant and golden brown, about 2 minutes. Remove from heat.
Transfer the steamed cauliflower (not with the water) into a food processor. Blender on high until smooth.
Add the garlic, and remaining ingredients and process again until smooth. Taste and adjust seasonings as needed.
