A warm, sweet, and comforting breakfast casserole made with simple pantry ingredients. Ready in just 30 minutes, it’s perfect for busy mornings and features soft, custard-soaked bread with tender, spiced apples.
For best results, use day-old or slightly stale bread. If using fresh bread, toast cubes at 350°F for 5-7 minutes to dry them out. Let the casserole rest for 5 minutes after baking to allow the custard to set. To make ahead, assemble the casserole the night before, cover, and refrigerate. Add 5 extra minutes to baking time if starting from cold.
