Cauliflower Au Gratin with Ham

Cauliflower Au Gratin is a delicious easy to make the alternative to Potatoes Au Gratin that I love making when I am craving a comfort food casserole. It combines Healthy Cauliflower, heavy cream, half and half cream, Swiss cheese, parmesan cheese, and smoky ham for an all-star casserole to serve your family this winter.

Have you ever craved your favorite comfort foods yet thought  I think I’ll skip it due to excessive carbs and calories? I definitely have thought the same thing– better not bother with eating that due to all the carbs and calories.

Cauliflower Au Gratin with Ham

Which is exactly why I started going through old recipes to figure out ways I could enjoy my favorite comfort food casseroles or something very similar. The Potatoes Au Gratin was one I decided I could do something fairly minimal to achieve  a delicious lower calorie version of something I love so dearly by omitting the potatoes and substituting cauliflower.

Make no mistake this isn’t a diet food of any sort it still retains it’s rich delicious comforting flavors of heavy cream, half and half, as well as real butter and flour so if you are watching your weight don’t go overboard — however, enjoy a lower calorie version to curb that craving for your favorite comfort food.
