Ingredients for Cauliflower Gratin Casserole…

Every dinner deserves a vegetable side, and this one allows you to prepare ahead, bake and reheat before serving.

CAULIFLOWER: When buying cauliflower, look for a large head without many leaves. You will need about 2 to 2.5 pounds for a 9 x 13 casserole baking dish.

CHEDDAR CHEESE: For this recipe, we prefer sharp cheddar cheese, and already shredded for easy prep.

PARMESAN CHEESE: We prefer grated Parmigiana-Reggiano cheese over any other brands. It offers the most health benefits and nutrients than any other brand of grated parmesan cheese.

HEAVY CREAM: Choose heavy cream, not whipping cream.

SEASONINGS: You will need some garlic powder, onion powder, cayenne pepper, salt, and black pepper for this recipe.

DIJON MUSTARD: Choose a jar of French “coarse” ground Dijon mustard. You will only need about 2 teaspoons, and it will enrich the flavors in the cheese sauce.

PANKO BREADCRUMBS: It’s best to choose Japanese-style panko breadcrumbs. Other brands of “so-called” panko are full of preservatives and unwanted additives.

FRESH PARSLEY: Choose fresh Italian parsley for the breadcrumb mixture and garnish before serving.

Easy Steps to Make this Casserole…
