What You’ll Need for This Cozy Casserole
This easy Croissant Breakfast Casserole recipe uses simple ingredients you likely have on hand. I love how the flaky, buttery brunch bake comes together with pantry staples. You’ll find everything feels familiar and comforting.
Let’s gather our cozy ingredients for a perfect golden baked croissant and egg dish.
For the casserole base
- Croissants – Stale or day-old croissants work beautifully here, but fresh ones are just as good. Tear them into rustic chunks for the best texture.
- Eggs – Large eggs are ideal for creating that rich, custardy base.
- Whole Milk – Whole milk gives the casserole the perfect creamy consistency—don’t skimp here.
- Heavy Cream – This adds a luscious richness to the custard. If you’re in a pinch, half-and-half can work, but cream is best.
- Vanilla Extract – Pure vanilla extract makes all the difference in flavor.
- Ground Cinnamon – Just a hint for warmth—don’t overdo it.
- Salt – A little goes a long way to balance the sweetness.
For the filling
- Cream Cheese – Softened at room temperature so it blends seamlessly into the casserole. Cut it into small cubes for even distribution.
- Fresh Blueberries – Bursting with juicy sweetness—frozen can work in a pinch, but fresh is best.
- Fresh Raspberries – Their tartness balances the richness perfectly.
For the topping
- Granulated Sugar – Adds just the right amount of sweetness to the custard.
- Light Brown Sugar – Pack it for that deep, caramel-like flavor.
- Powdered Sugar – A snowy dusting right before serving makes it look (and taste) irresistible.
Croissant Breakfast Casserole
Ingredients
- 8 large croissants
- 8 large eggs
- 2 cups whole milk
- 1 cup heavy cream
- 1 tsp vanilla extract
- 1/2 tsp ground cinnamon
- 1/4 tsp salt
- 8 oz cream cheese softened at room temperature
- 1 cup fresh blueberries
- 1 cup fresh raspberries
- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar
- powdered sugar for dusting
Method
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick cooking spray.
- Tear the croissants into 1 to 2-inch chunks and spread them evenly in the prepared baking dish. Scatter the blueberries and raspberries over the croissant pieces.
- In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, and salt until the mixture is completely smooth and the sugars are dissolved.
- Cut the softened cream cheese into small cubes and distribute them evenly over the croissant and berry mixture. Slowly and evenly pour the egg mixture over the entire casserole, ensuring all the croissant pieces are moistened. Gently press down on the top with a spatula to help the bread soak up the custard.
- Let the casserole stand for 15 minutes to allow the bread to fully absorb the liquid. Bake for 45 to 55 minutes, or until the top is puffed and golden brown and the center is set (a knife inserted near the center should come out clean).
- Remove the casserole from the oven and let it rest for 10 minutes before serving. Dust the top generously with powdered sugar just before slicing.

My Favorite Pro Tips for a Perfect Bake
After making this savory Croissant Breakfast Casserole countless times, I’ve learned a few tricks. First, if you want a flavor swap, try using a sharp cheddar instead of cream cheese for a more savory twist. For a prep tip, always let your casserole sit for 15 minutes before baking so the bread soaks up all that custardy goodness.
If you’re reheating leftovers, cover them with foil to prevent the top from over-browning. And for another great make-ahead dish, my overnight oats are a lifesaver on busy mornings. Finally, for a diet tweak, you can use a mix of milk and half-and-half if you don’t have heavy cream.
A Look at the Nutrition in Your Casserole
This dish is a comforting treat that brings joy to the table, and it offers some nutritional benefits too. The eggs provide a great source of protein to help keep you full, while the berries add a dose of antioxidants and vitamins. Using whole milk and cream contributes to the calcium content, which is great for bone health.

How to Lighten Up Your Cozy Casserole
If you’re looking for a lighter version of this holiday breakfast bake, I have a few simple swaps. You can use low-fat milk instead of whole milk and reduce the amount of brown sugar by half. For a dairy-free option, try using your favorite unsweetened almond or oat milk blend.
Another idea is to add more berries for natural sweetness and fiber. For more healthy inspiration, my avocado breakfast bowl is a nourishing choice. You can also check out this Southern Living sweet variation for a different take on berries.
How to Serve Your Casserole with Love
I love serving this warm, creamy berry stuffed breakfast casserole right from the oven on a big platter. The smell alone will have everyone gathering in the kitchen, just like at my grandma’s house on Sunday mornings. It’s perfect with a side of crispy bacon or a simple fresh fruit salad.
For a full brunch spread, pair it with a fresh pot of coffee or a citrusy mimosa. You can also explore my smoked salmon benedict for another elegant brunch idea.
Common Mistakes to Avoid for the Best Bake
Let’s talk about a few common pitfalls so your Croissant Breakfast Casserole turns out perfectly every time. First, don’t skip the step of letting the casserole sit before baking, or the bread won’t absorb all the custard. Second, avoid overbaking, which can make the eggs rubbery instead of soft and set.
Lastly, be sure to use day-old or slightly stale croissants for the best texture, as fresh ones can get too soggy. For more cooking wisdom, the Food Network ingredient combinations offer great guidance. And if you love eggs, my cheesy baked eggs are another simple, fail-proof recipe.
How to Store and Enjoy Later
I often make a double batch of this baked savory croissant strata because it reheats so beautifully. Let the casserole cool completely, then cover it tightly with plastic wrap or transfer slices to an airtight container. It will keep in the fridge for up to three days, perfect for easy breakfasts all week.
To reheat, just pop a portion in the microwave or warm it in the oven until cozy again. For more make-ahead magic, try my breakfast burrito recipe. You can also freeze individual slices for up to a month for a future lazy morning.

Your Croissant Casserole Questions Answered

Yes, cooked and crumbled bacon is a fantastic swap for sausage. It adds a delicious smoky flavor that pairs beautifully with the cheese and eggs. Just make sure it’s crisp so it doesn’t get soggy in the custard.
