Easy Cauliflower Au Gratin
As you have probably noticed I’m obsessed with 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.
What Pairs With Cauliflower Gratin
Greek Lemon Oregano Chicken – dish with minimal ingredients but so much flavor;
Pork Tenderloin With Seared Peaches – perfect for busy weeknight meal;
Steak Chateaubriand – French classic ready in under 30 minutes.

At this point you should have a silky smooth white sauce that works great in so many recipes.
3. Assemble Gratin
Transfer cooked cauliflower and potatoes into the 8 by 11 inches baking dish. Cover with a white sauce and carefully mix to combine the ingredients.
Sprinkle Panko breadcrumbs, drizzle with the remaining 2 tablespoon of melted butter and sprinkle 1/4 cup of Gruyere on top of the gratin.
4. Bake
Bake for 25 to 30 minutes until vegetables are tender.
Turn on the broiler and bake for 2-3 minutes until top of the gratin is golden brown. Yum!
