Cheesy Garlic Egg Croissant Bake

Featured in: Sunbeam Starts

This decadent bake combines torn buttery croissants with a rich mixture of eggs, milk, cream, and three flavorful cheeses. Aromatic minced garlic and fresh herbs add savory depth while melted butter ensures golden, crisp edges. After assembly, the croissant pieces soak up the custard before baking to set and develop a golden crust. Perfect served warm, finished with extra herbs for brightness. Adapt with sautéed veggies or alternate cheeses as desired. Pair with a crisp salad for a well-rounded brunch or cozy breakfast centerpiece.
