Preheat your oven to 350°F and generously grease a 9x13-inch baking dish with cooking spray or butter. Using a day-old croissant base ensures the chunks absorb the custard beautifully without turning mushy, which is key for this High Protein Blueberry Cream Cheese Croissant Casserole.

Tear all 8 large day-old croissants into 2-inch chunks and spread them evenly across the prepared baking dish. Drizzle 2 tbsp melted unsalted butter and 1 tsp vanilla extract over the croissant pieces, tossing gently to coat every chunk for maximum buttery flavor.

In a large mixing bowl, whisk together 8 large eggs, 1 cup whole milk, 1 cup plain Greek yogurt, 1/2 cup vanilla protein powder, 3 tbsp honey, 1 tsp ground cinnamon, and 1/4 tsp ground nutmeg until completely smooth and lump-free. Pour this velvety protein custard evenly over the croissant chunks, pressing pieces down gently to soak.

In a medium bowl, beat 8 oz softened full-fat cream cheese with 1/4 cup powdered sugar, 2 tbsp fresh lemon juice, and 1 tsp lemon zest until silky smooth. Drop generous spoonfuls of this tangy cream cheese mixture across the top of your High Protein Blueberry Cream Cheese Croissant Casserole, then swirl lightly with a knife.

Scatter 2 cups fresh blueberries evenly over the casserole, then sprinkle 2 tbsp granulated sugar directly over the berries to encourage them to burst and caramelize during baking. Finish by distributing 1/4 cup sliced almonds across the top for a golden, nutty crunch that elevates every bite.

Bake your High Protein Blueberry Cream Cheese Croissant Casserole uncovered at 350°F for 38-40 minutes, until the custard is fully set in the center, the top is deep golden brown, and the blueberries are bubbling. Insert a knife into the center — it should come out clean with no wet custard.

For the best High Protein Blueberry Cream Cheese Croissant Casserole results, remove from the oven and let it rest uncovered for 10 minutes before slicing. This allows the custard to fully set, making clean, beautiful portions. Serve warm as-is or with a light drizzle of honey and a dusting of powdered sugar.
