This Blueberry Croissant Breakfast Bake transforms buttery croissants into a delicious bread pudding-style casserole studded with juicy blueberries. The croissants soak up a sweet custard mixture, creating a soft, pudding-like interior with crispy, golden edges. As it bakes, the blueberries burst, releasing their flavor throughout the dish. Simple to prepare with basic ingredients, this make-ahead breakfast casserole is perfect for brunches, holiday mornings, or whenever you want a special breakfast without much fuss.
