Comfort food recipe that has quickly become one of the favorites in my house. Cauliflower Au Gratin with the addition of potatoes is so creamy, cheesy and such a delicious side dish for holidays as well as for Sunday night dinner.

Easy Cauliflower Au Gratin

As you have probably noticed I’m obsessed with French food and particularly Gratins. Recently I’ve been making them non-stop. My Eggplant Gratin, Potato Zucchini Gratin or Chicken, Potato and Bacon Gratin are among my most popular recipes at home for a reason.

Whenever I have some kind of celebration at my house, I make sure to prepare one of those Gratins and they always disappear quickly.

Baked to their bubbly and crispy perfection, gratins are so satisfying and make a perfect side dish for any occasion.

My today’s recipe is inspired by Ina Garten Cauliflower Gratin. I first made it a few years ago and immediately fell in love with the simplicity of preparation process and the excellent taste of the dish.

I love Ina’s original version of the recipe but I decided to add potatoes for more volume and nutrition.

What I really like about this Cauliflower Au Gratin or any other gratins is that you can make them ahead of time, which is very convenient for Thanksgiving or Christmas.

Just assemble everything in a baking dish, cover with a foil and store in a fridge for a few hours or even overnight until you’re ready to bake it.

In this recipe I used Gruyere Cheese. I absolutely love it. It has a nice flavor, a little crispy bite and works amazing in so many recipes. If you don’t have Gruyere, use my suggestions below.

Substitute For Gruyere

Any other hard cheese with distinctive flavor will work. Here are some of my suggestions:

  • Parmijiano-Reggiano;
  • Grana Padano;
  • Aged Gouda;
  • Aged Cheddar;
  • Aged Provolone.Baked Cauliflower Au Gratin Recipe
