Step‑by‑Step Instructions for Lemon Berry Croissant Breakfast Casserole
Step 1: Prepare Baking Dish
Begin by lightly greasing a 9×13-inch baking dish with nonstick spray. This ensures that your Lemon Berry Croissant Breakfast Casserole won’t stick and will bake evenly, making it easy to serve. Preheat your oven to 350°F as you prepare the croissants for toasting.
Step 2: Toast Croissants
Spread the cubed croissants onto a baking sheet in a single layer. Place them in the preheated oven for 7-10 minutes, keeping an eye on them until they turn golden and crispy. This step is vital to avoid sogginess in the final casserole, creating a perfect texture to soak up the custard.
Step 3: Mix Custard
In a large mixing bowl, beat together softened cream cheese and granulated sugar using an electric mixer until the mixture is creamy and smooth. Incorporate the room-temperature eggs one at a time, then gently mix in half and half, lemon juice, lemon zest, vanilla extract, and a pinch of salt until thoroughly combined, creating a luscious custard for your casserole.
Step 4: Assemble Casserole
Layer half of the toasted croissant cubes at the bottom of the greased baking dish. Top the croissants with half of the mixed berries, followed by half of the custard mixture. Repeat this layering process with the remaining croissants, berries, and custard, pressing down gently to ensure everything is submerged and well-coated.
Step 5: Chill Overnight
Cover the assembled casserole tightly with aluminum foil and place it in the refrigerator overnight. This allows the croissants to absorb the custard fully, enhancing the flavors and creating a moist, flavorful Lemon Berry Croissant Breakfast Casserole that’s ready to bake in the morning.
Step 6: Bake
When ready to bake, remove the casserole from the refrigerator and preheat your oven again to 350°F. Bake the casserole covered for 30 minutes, then uncover it and bake for an additional 15 minutes until the custard is set and the top is lightly golden. You’ll know it’s done when the edges start to puff up and the center is firm.
Step 7: Make Glaze
While the casserole is baking, whip together the powdered sugar and lemon juice in a small bowl until smooth to create a zesty glaze. Set this aside so it’s ready to drizzle over the warm Lemon Berry Croissant Breakfast Casserole just before serving, adding a sweet finishing touch to your brunch delight.

Make Ahead Options
These Lemon Berry Croissant Breakfast Casserole preparations are a lifesaver for busy mornings! You can assemble the casserole up to 24 hours in advance by prepping all components and layering them in the greased baking dish. Be sure to cover the dish tightly with foil to prevent any drying out. For best results, refrigerate overnight, allowing the croissants to absorb the custard fully. When you’re ready to bake, simply pull the casserole out of the fridge, preheat the oven, and bake covered for 30 minutes, followed by an additional 15 minutes uncovered. This makes enjoying a delicious, homemade breakfast effortless while letting you savor time with your family!
Expert Tips for Croissant Breakfast Casserole
Keep Croissants Crunchy: Toast the croissants until golden to prevent sogginess. This crucial step ensures that your Croissant Breakfast Casserole remains light and fluffy.
Room Temperature Eggs: Always use room-temperature eggs for a smoother custard mixture. This helps achieve a creamier texture that’s essential in this dish.
Check Liquid Levels: Before baking, verify that most of the custard is absorbed. If there’s excess liquid, pour it off to avoid a runny casserole.
Bake Time Caution: If using a glass baking dish, be mindful of baking times, as they may vary. Glass retains heat differently, which can affect cooking regularity.
Flavor Variations: Don’t hesitate to personalize your dish! Swap in seasonal fruits or different extracts for exciting twists that keep brunch appealing.
How to Store and Freeze Croissant Breakfast Casserole
Fridge: Refrigerate any leftovers tightly covered for up to 4 days. This keeps your Croissant Breakfast Casserole fresh and delicious for quick breakfasts throughout the week.
Freezer: For longer storage, freeze the assembled but unbaked casserole tightly wrapped in plastic wrap and aluminum foil for up to 2 months. Thaw in the fridge overnight before baking.
Reheating: Reheat leftovers in the microwave for a quick option, or bake in a preheated oven at 350°F for about 15-20 minutes until heated through, restoring that fluffy texture.
Chill Before Baking: If preparing in advance, assemble the casserole and chill it in the fridge overnight, or up to two days, to enhance the flavors before baking.

Croissant Breakfast Casserole Recipe FAQs
What type of croissants should I use for the casserole?
Absolutely! I recommend using large bakery croissants. They provide the best flaky texture and buttery flavor. Avoid using prepackaged tube croissants, as they don’t yield the same delightful results.
How long can I store leftovers?
You can refrigerate any leftovers tightly covered for up to 4 days. This way, you can enjoy your Croissant Breakfast Casserole for quick breakfasts or snacks during the week. Just reheat in the microwave or oven!
Can I freeze the casserole?
Yes, you can! To freeze, assemble the casserole but do not bake it. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored for up to 2 months. When ready to bake, simply thaw it in the fridge overnight before baking as per the instructions.
What if my casserole turns out soggy?
Very common! To prevent sogginess, ensure you toast the croissants well before assembling. They should be crispy, almost like croutons, so they can absorb the custard without becoming mushy. Additionally, check that most of the custard is absorbed before baking; if there’s excess liquid, it’s best to pour it off.
Are there any dietary considerations I should be aware of?
Yes, indeed! If you have allergies, make sure to check the ingredients. This recipe contains eggs and dairy. For a gluten-free option, you can substitute the croissants with thick gluten-free bread, making sure to toast it first. Always consult with your guests regarding dietary restrictions for a worry-free brunch!
How can I enhance the flavor of my casserole?
The more the merrier! You can experiment with different fruits or spices. Seasonal berries, like strawberries or peaches, bring a fresh twist. Additionally, substituting lemon with orange or maple can impart delightful new flavors. Don’t hesitate to get creative!
