Step‑by‑Step Instructions for Croissant Breakfast Casserole
Step 1: Prepare Croissants
Begin by preheating your oven to 350°F (175°C). Cube your large bakery-style croissants and spread them evenly on a baking sheet. Toast the croissant pieces in the oven for 7-10 minutes, until they are golden brown and slightly crisped. Remove them from the oven and let them cool, as this step ensures they absorb the custard without becoming soggy.
Step 2: Make Custard
In a large mixing bowl, beat together softened cream cheese and granulated sugar until smooth and creamy. Gradually add in your large eggs, stirring well after each addition. Pour in the half and half along with the fresh lemon juice, lemon zest, vanilla extract, and a pinch of salt. Whisk until fully combined and the mixture is velvety, setting the stage for your Croissant Breakfast Casserole’s rich flavor.
Step 3: Assemble Casserole
Grease a 9×13-inch baking dish to prevent sticking. Layer half of the toasted croissant pieces on the bottom of the dish, followed by half of your vibrant berries. Next, pour half of the creamy custard mixture over the layers, ensuring even coverage. Repeat with the remaining croissants and berries, pressing down gently on each layer to help them soak up the custard. Cover the dish and refrigerate overnight to enhance flavor absorption.
Step 4: Bake
When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature while the oven heats. Cover the dish with aluminum foil and bake for 30 minutes. Then, remove the foil and bake for an additional 15 minutes, until the center is set and the top is golden. You’ll know it’s done when it springs back lightly when touched.
Step 5: Make Glaze
As the casserole bakes, prepare the optional glaze by whisking together powdered sugar, lemon juice, and a splash of vanilla extract in a small bowl. Stir until the mixture is smooth and drippy, adjusting the consistency with more sugar or a touch of lemon juice if needed. This simple glaze adds a delightful sweet finish to your Croissant Breakfast Casserole.
Step 6: Serve
Once baked, remove the casserole from the oven and allow it to cool for a few minutes. Drizzle the glaze generously over the top to create an attractive finish. Serve the casserole warm, optionally dusting individual portions with additional powdered sugar for an extra touch of sweetness. This delightful Croissant Breakfast Casserole is ready to be enjoyed by all!

Expert Tips for Croissant Breakfast Casserole
-
Perfectly Toasted: Toast your croissants until golden brown to enhance their structural integrity. Sogginess often results from under-toasting.
-
Use Half and Half: For a rich custard, always use half and half instead of milk. This prevents the casserole from becoming runny, ensuring a creamy texture.
-
Overnight Refrigeration: Letting the casserole sit overnight allows the flavors to meld beautifully and prevents excess liquid from pooling during baking.
-
Check for Doneness: If baking directly from the fridge, let the casserole rest at room temperature for 30-60 minutes. Use a knife to check doneness—the blade should come out clean.
-
Glaze with Care: Drizzling glaze while still warm enhances the caramelization. Adjust the glaze’s consistency as needed for a smooth finish over your Croissant Breakfast Casserole.

Croissant Breakfast Casserole Recipe FAQs
How do I choose the right croissants for the casserole?
Absolutely! For the best results, opt for large bakery-style croissants, as they’re flakier and have more flavor than pre-packaged varieties. Look for croissants that are golden brown, soft to the touch, and fresh—these will make your casserole wonderfully buttery and delicious!
What’s the best way to store leftovers?
You can store any leftover croissant breakfast casserole tightly covered in the refrigerator for up to 4 days. This ensures it maintains its creamy texture and delicious flavor. Just make sure it’s completely cooled before wrapping it up to keep it fresh!

What if my casserole turns out soggy?
Don’t worry; this can be a common issue! To prevent sogginess, ensure that you toast the croissant pieces enough so they become pleasantly crisp before assembling.
