This creamy mashed cauliflower gratin is healthier than the potato version but just as delicious.

This is another Thanksgiving side idea. I know there’s been an unusual amount of savory recipes lately. I’m gearing up for major baking for Thanksgiving though!

Potato gratin is one of Mr. K’s favorite dishes. He loves all that cheese and bacon. I don’t make it too often because I know how unhealthy it is. So after discovering cauliflower as a great potato substitute, I decided to try making his favorite with cauliflower instead. The verdict? He loved it!

I left the room for a minute and when I came back, the dish was empty. He asked me to make him more. Yes, I’m pretty shocked too…It’s almost as shocking as when I found him awake before me last Sunday and cleaning the house.

He also had brought me up breakfast in bed. Okay, it was just bread we had bought from the bakery the night before, but still. I can’t remember the last time he brought me up any meal in bed. So maybe he wasn’t quite himself when he declared his love for this dish, but it’s definitely a keeper and one that I really enjoy too.

As I discussed in my mashed cauliflower post, cauliflower mimics the texture of potato so well. With all the added cheese and bacon, it really masks any vegetable flavor.

This creamy mashed cauliflower gratin is healthier than the potato version but just as delicious.


  • 1 recipe mashed cauliflower (see note)
  • 1 cup shredded cheddar cheese
  • 1/2 cup Parmesan cheese
  • 6 strips cooked bacon finely chopped


  1. Prepare two small casserole dishes (mine each hold 12 oz water when poured to the brim). Make the recipe for mashed cauliflower.

  2. Preheat oven to 375°F. Add mash to the bottom of the two casserole dishes. Mix 2 strips of the finely chopped bacon into each mash. Sprinkle 1/2 cup of cheddar cheese on top of each mash. Sprinkle 1/4 cup of shredded parmesan cheese on top of each mash. Finally sprinkle 1 strip of finely chopped bacon on top of each dish.

  3. Bake about 15 minutes until cheese is melted. You can turn oven to a low broil for about 1-2 minutes to get the cheese to brown and bubble. Garnish with fresh chopped parsley before serving, if desired.


  • Follow the instructions for this Mashed Cauliflower recipe. You can boil the cauliflower in water instead of broth if you like for this gratin since there will be so much flavor from the cheese and bacon.
