To roast your garlic cloves, make a little aluminum foil tray and place your garlic cloves in. Drizzle a tablespoon of olive oil in and bake at 400°F for about 10-12 minutes.
While the garlic is roasting, cut your cauliflower into evenly sized florets and place them into a steam basket over simmering water. Make sure the lid you’re using is a good fit!
Steam until a fork pierces through easily- about 10 minutes. Your garlic cloves should look like this when done:
Drain all the water from the pot and place your steamed cauliflower back into it. Add butter and your seasonings, as well as the roasted garlic cloves.
Using an immersion blender, blend until smooth and creamy.
