Turn crock pot on low for 2.5 to 3 hours (we just set it to run for 3 hours, and our crock pot kept it warm until morning.)

Recipe
Wake up to the cozy aroma of this slow-cooked French toast casserole; rich, custardy, and perfectly spiced with cinnamon and nutmeg. Made with your favorite bread (challah is a dream), it’s the easiest way to serve a warm, comforting breakfast with almost no morning prep.
