Blueberry Cream Cheese Croissant Casserole (Printable)

Buttery croissant bake layered with sweetened cream cheese and fresh blueberries, ideal for weekend brunch or special occasions.

# What You Need:

→ Croissant Base

01 - 6 large croissants, preferably day-old, cut into large cubes

→ Cream Cheese Filling

02 - 8 oz cream cheese, softened
03 - 1/3 cup granulated sugar
04 - 2 large eggs
05 - 1 cup whole milk
06 - 1 tsp pure vanilla extract
07 - Zest of 1 lemon (optional)

→ Blueberry Layer

08 - 1 1/2 cups fresh or frozen blueberries
09 - 1 tbsp all-purpose flour (for tossing with blueberries)

→ Topping

10 - 2 tbsp powdered sugar (for dusting after baking)
11 - Maple syrup or whipped cream for serving (optional)

# How To Cook:

01 - Preheat oven to 350°F. Grease a 9x13-inch baking dish with butter or non-stick spray.
02 - Scatter half of the cubed croissants evenly across the bottom of the prepared baking dish.
03 - In a medium bowl, beat together the softened cream cheese and granulated sugar until smooth and creamy. Add the eggs, whole milk, vanilla extract, and lemon zest, mixing until fully combined.
04 - Place the blueberries in a small bowl and toss with the all-purpose flour to coat evenly, which prevents sinking during baking. Sprinkle half of the coated blueberries over the first croissant layer.
05 - Pour half of the cream cheese mixture over the croissants and blueberries. Layer the remaining croissant cubes and blueberries on top. Pour the remaining cream cheese mixture over everything, pressing down gently so the croissants absorb the custard.
06 - Let the assembled casserole rest at room temperature for 10 minutes so the croissants soak up the custard. Alternatively, cover tightly and refrigerate overnight for a make-ahead preparation.
07 - Bake in the preheated oven for 35 to 40 minutes, until the center is set and the top is golden brown.
08 - Allow the casserole to cool for 10 minutes. Dust generously with powdered sugar and serve warm with maple syrup or whipped cream if desired.

# Expert Tips:

01 -
  • It turns stale bakery croissants into something so indulgent that nobody believes it took fifteen minutes of actual work.
  • The cream cheese custard seeps into every flaky layer and creates pockets of sweetness that taste like the best part of a danish.
  • You can assemble it the night before and simply bake it in the morning, which makes you look incredibly organized.
02 -
  • If you skip the flour toss on frozen blueberries you will end up with a purple swamp instead of a pretty casserole, and I learned this the hard way.
  • Pressing the top layer of croissants down into the custard before baking ensures that every piece gets soaked rather than drying out in the oven.
03 -
  • Substituting half the milk with heavy cream turns a wonderful casserole into something downright unforgettable, and I only do this when I want to impress.
  • The lemon zest might seem optional but it is the quiet ingredient that makes people pause after the first bite and ask what makes it taste so special.
