Ham and Cheese Breakfast Casserole

We're heading into the fall holiday season, which means that brunch casseroles are about to enjoy their heyday. So we decided to revisit one of our most popular recipes ever — a recipe published several years ago for a breakfast bake with bread, pancetta, Gruyere, and eggs. I'm afraid that I'll sound horribly hyperbolic if I talk about this recipe too long. It's rich, eggy, and unbelievably, incredibly delicious. This is one to memorize, folks, and to pull out for in-laws and overnight guests. It may just be the very best brunch casserole we've ever made.
