Overnight Breakfast is the perfect Christmas morning or New Year’s Day breakfast casserole. Or brunch if you partied into the wee hours of the morning. You make it the night before and bake it in the morning. Low maintenance! What’s even better about this is you can be totally creative in what ingredients to use. I’ve made it with leftover turkey and switched out the cheddar for Swiss and Brie. I’ve used stale croissants, made sweet versions with raisin bread….the possibilities are endless!
