WHAT IS KETO CAULIFLOWER GRATIN?

Cauliflower gratin is a cheesy dish that uses cauliflower as the main ingredient instead of potatoes or another starchy vegetable.

Did we say cheese? This dish combines heavy cream and cheese to not only make a creamy cheese sauce, but cheese on top makes it all the better.

This recipe is perfect for a side dish with any number of main courses!

WHAT DOES GRATIN MEAN?

Gratin means “a dish with a browned crust of breadcrumbs or melted cheese.”

The word originated in French cuisine, which brought with it the use of shallow dishes to cook in. The food is also traditionally served in whatever baking dish it is cooked in.

While this dish doesn’t use breadcrumbs to create a crunchy top, the cheddar cheese on top helps to create a gooey, browned crust after time in the oven.

CHOOSING A GOOD PARMESAN CHEESE

Like all cheeses parmesan cheese can come in many different shapes, sizes, and qualities. You’re definitely going to want to make sure to get (if nothing else) a decent parmesan cheese to make this dish absolutely delicious.

Here are a few things to keep in mind when buying parmesan cheese for this recipe.

QUALITY COSTS EXTRA

As you already know, higher quality means higher price. Cheese is no exception.

Your local grocery will more than likely have two cheese sections. One will be the regular cheese section where you can find slice cheese, grated cheese, etc. The second will (hopefully) be an artisan cheese section that has all kinds of different cheeses.

This section is definitely the one you want to be buying parmesan from. It’s real, authentic, and should still have rind attached (you’re going to want to use this in the recipe).

It will cost you a few dollars extra, but will be totally worth it.

AGE DOESN’T MATTER THAT MUCH

You might have the option to choose from aged parmesans. If you run into this, don’t worry too much about it. Pick whichever one you’d like, but do know the older ones will have a stronger taste.

You’re really only looking for the quality taste of the parmesan in the sauce, so an aged cheese isn’t really going to do you much good unless you want a stronger tasting sauce.

DO I HAVE TO USE KOSHER SALT?

No, you don’t have to. In fact, you can use whatever kind of salt you prefer in the water when boiling your cauliflower.
