Step‑by‑Step Instructions for Sweet Croissant Breakfast Casserole
Step 1: Prep Baking Dish
Begin by greasing a 9×13 inch baking dish with butter or cooking spray, ensuring all sides are coated to prevent the casserole from sticking. This will help create a lovely golden crust on your Sweet Croissant Breakfast Casserole. Set the dish aside while you prepare the croissants and berries.
Step 2: Prepare Croissants
Cut day-old or slightly stale croissants into 1-inch pieces, allowing them to soak up the custard more effectively. Spread the croissant pieces evenly in the greased baking dish, then scatter your chosen mixed berries on top, making sure to distribute both ingredients well for an even flavor in each mouthful.
Step 3: Mix Custard
In a large mixing bowl, combine softened cream cheese, milk, sugar, eggs, vanilla extract, lemon zest, and ground cinnamon. Whisk the mixture until smooth and creamy—this should take about 2 to 3 minutes of vigorous whisking. The custard should be well-blended with no lumps, ready to envelop the croissants and berries.
Step 4: Combine Layers
Pour the smooth custard mixture evenly over the layered croissants and berries in the baking dish. Use a spatula to gently press down the croissant pieces, ensuring they absorb the custard evenly. You want to see the custard pooling around the ingredients, enveloping them for the ultimate flavor fusion.
Step 5: Refrigerate
Cover the baking dish tightly with plastic wrap or aluminum foil and place it in the refrigerator for at least 8 hours, or overnight. This critical step allows the croissants to soak up the custard fully, enhancing the flavors of your Sweet Croissant Breakfast Casserole for a delightful morning treat.
Step 6: Bake
When ready to bake, preheat your oven to 350°F (175°C). Once heated, remove the cover from the dish and place it in the oven. Bake for 30 minutes, then uncover and bake for an additional 15 minutes, or until the top is golden brown and the custard is set, with a slight jiggle in the center.
Step 7: Prepare Glaze
While your casserole is baking, in a small bowl, whisk together sifted powdered sugar, heavy cream, and vanilla bean paste until the mixture is smooth and shiny. This glaze will add a lovely finishing touch to your Sweet Croissant Breakfast Casserole once it cools down.
Step 8: Finish Casserole
Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes. Drizzle the prepared glaze generously over the top, and if desired, dust with additional powdered sugar for an extra touch of sweetness and presentation. Serve warm and savor each delicious bite!

How to Store and Freeze Sweet Croissant Breakfast Casserole
