This ensures even soaking and avoids dry spots, helping your buttery croissant egg and cheese bake recipe bake up perfectly. 4.

Behind the Recipe
My first taste of a buttery croissant breakfast bake happened at a friend’s Christmas brunch years ago. They served a croissant and cheese casserole that had the perfect combination of crispy top, tender interior, and buttery flavor. I remember going back for thirds—and immediately asking for the recipe. That single dish sparked my obsession with creating the ultimate croissant breakfast bake.
Back in my kitchen, I started experimenting with different versions: using cheddar, Gruyère, mozzarella; adding spinach, sautéed mushrooms, caramelized onions; and testing variations of custard ratios.

The edges of the croissants crisp up beautifully while the centers stay luxuriously creamy—a key reason why this croissant breakfast casserole is so beloved.
