Easy Overnight Breakfast Casserole
Blueberries shine in this Blueberry Croissant Breakfast Casserole. Flaky, bakery croissants are layered with fresh blueberries and a creamy cheesecake-like custard made from cream cheese, sugar, eggs, milk, and a touch of vanilla. The casserole can be baked immediately or refrigerated and baked the next morning, making it perfect for busy mornings or entertaining. The result is rich, tender, and bursting with blueberry flavor—great for both breakfast and dessert.

How to Make Blueberry Croissant Breakfast Bake
This casserole is straightforward to prepare. Chop bakery croissants into bite-sized pieces and spread them in a greased 9×13-inch baking dish. Scatter fresh blueberries over the croissants. In a medium bowl, beat softened cream cheese with sugar, eggs, and vanilla until smooth. Add milk and mix until combined. Pour the custard evenly over the croissants and blueberries. Let it sit for about 20 minutes so the croissants absorb the custard, or cover and refrigerate overnight to bake the next morning.
Important: use fully baked croissants from the bakery. Do not substitute refrigerated crescent roll dough; they are not the same and will change the texture and flavor of the finished dish.

What to Serve with Blueberry Breakfast Casserole
This casserole is versatile—serve it for breakfast, brunch, potlucks, or as a dessert. Leftovers reheat well and are delicious topped with a scoop of vanilla ice cream. For a savory contrast at breakfast, pair the casserole with bacon, sausage, or cheesy grits. It also pairs nicely with simple fruit salads and savory breakfast sliders to round out a buffet.
