Pour sauce over prepared cauliflower in dish. If making this dish ahead, add an extra 1/4 cup of half and half or milk to the liquid.

  6. Wipe out or wash the pan used to make the sauce.

  7. Melt the remaining 1 tablespoon of butter sprinkle in the pan. Sprinkle ½ cup of Panko bread crumbs into the pan, use a spatula to move the crumbs around so they don't burn while cooking.
