A quick and comforting breakfast casserole featuring cubed stale bread soaked in a seasoned egg custard with ham and a blend of cheddar and mozzarella cheeses. Perfect for busy mornings, brunch, or dinner.
Use stale or day-old bread to prevent sogginess. Toast fresh bread if needed. Let the casserole rest after baking for cleaner slices. Mustard in the egg mixture brightens flavor. Can be assembled the night before and refrigerated; add 10 minutes to baking time if doing so. Tent with foil if browning too fast.
