Cauliflower au gratin is a great way to get that same rich, cheesy texture with a vegetable instead of potatoes. It reduces some of the carbs, as well. Though the calories in this dish are pretty high as it uses tons of cheese and cream. However, it makes a great dish for guests. Everything in moderation, right? This dish is a bit more saucier than au gratin potatoes as it does not take cauliflower as long to bake as potatoes. However extra sauce is not a bad thing at all. I’m hoping you will enjoy this cauliflower au gratin dish just as much potatoes. It’s so much easier because you don’t have to peel potatoes!
