Spread English muffins pieces evenly on an ungreased baking sheet and broil for 2 minutes. Flip muffin pieces over then continue to broil 2 minutes or until nicely toasted. Set aside.

Spray a 13 x 9-inch baking dish with cooking spray. Evenly layer half of the Canadian bacon followed by an even layer of all of the toasted English muffin pieces followed by an even layer of the remaining Canadian bacon.

In a large measuring cup or mixing bowl (something with a spout) whisk together eggs, milk and all Casserole seasonings until well blended. Pour egg mixture evenly over casserole. Cover with plastic wrap and refrigerate overnight.

The next morning, preheat oven to 375 degrees F and remove casserole from refrigerator and let rest at room temperature for 15 minutes. Remove plastic wrap then cover casserole tightly with foil. Bake for 30 minutes then uncover and continue to bake until a toothpick inserted into center of casserole comes out clean, about 15 - 20 minutes longer.

Prepare hollandaise sauce when there is about 5 minutes left of baking time. If you are expecting leftovers then serve Hollandaise Sauce over individual servings. If not expecting leftovers then you are welcome to pour it over the casserole.
