Ham and cheese croissant casserole is a comforting breakfast bake with buttery croissants, savory ham, creamy custard, and melted shredded mozzarella. It is simple enough for a relaxed weekend and attractive enough for guests. Assemble it ahead, keep it chilled, and bake it when everyone is ready to eat. The bread becomes tender inside while the cheese turns golden on top, making each portion rich, warm, and easy to serve.
What is ham and cheese croissant casserole?
This savory bread casserole combines croissant pieces, ham, cheese, eggs, milk, and cream. The egg mixture seasons every layer and creates a soft center with crisp edges.
Why this recipe works
Croissants provide butter and flavor without a complicated sauce. Dividing the cheese gives both melted pockets and a golden top.
