Berry croissant bake is that comforting breakfast casserole I turn to when I want to transform leftover pastries and fresh berries into something magic. This dish wins over everyone at my brunch table with its custardy middle and berry bursts, all finished with a powdered sugar snow.
I first made this bake the morning after a family holiday and everyone asked why we don't have it every weekend. There is something about the buttery croissants paired with tart berries that makes it an instant favorite.
Ingredients
- Croissants: Day old or slightly stale work best because they hold their structure in the custard, choose a good-quality bakery croissant for even more flavor
- Mixed berries: Use any combination like strawberries, blueberries, raspberries, blackberries, fresh is ideal but frozen works in a pinch
- Whole milk: The backbone of the custard, gives creamy richness
- Heavy cream: Adds luxurious texture and depth
- Large eggs: Binds the custard and gives the bake structure, use free-range eggs for that deep yellow yolk
- Vanilla extract: Brings in a cozy aroma and layers of flavor, go for pure extract if you can
- Granulated sugar: Sweetens the dish without overpowering the fruit
- Powdered sugar: For dusting, adds a beautiful finished look and extra sweetness
- Lemon zest (optional): Lifts the dish with a hint of brightness and keeps every bite lively
Step-by-Step Instructions
- Prepare the Baking Dish:
- Grease your nine by thirteen inch baking dish with butter or nonstick spray so nothing sticks and your slices come out clean
- Layer the Croissants:
- Cut your croissants into halves or quarters to create plenty of nooks for the custard, then arrange them in the baking dish overlapping slightly for good texture
- Add the Berries:
- Evenly scatter your prepared mixed berries across the croissant pieces, making sure to tuck some between the layers so every forkful gets fruit
- Mix the Custard:
- In a large bowl, whisk together eggs, whole milk, cream, sugar and vanilla until the mixture is completely smooth; this way every part of the bake gets infused with flavor
- Soak the Croissants:
- Slowly pour the custard mixture over the layered croissants and berries, pressing gently on the bread so it soaks up as much liquid as possible
- Rest Before Baking:
- Let the whole dish sit uncovered at room temperature for at least fifteen to twenty minutes, or cover and chill overnight for breakfast prep convenience
- Bake to Perfection:
- Bake in a preheated oven at three hundred fifty degrees Fahrenheit for thirty five to forty minutes until the top is golden and the custard jiggles only slightly in the center
- Finish and Serve:
- Let the bake cool for a few minutes, then dust with powdered sugar before serving; add a drizzle of maple syrup or whipped cream if you want a little extra decadence

The bright pop of lemon zest is my secret weapon in this recipe. My kids now love zesting lemons just to help with the "magic sprinkle" that makes the whole dish sparkle with freshness.
Storage Tips
This berry croissant bake will keep for up to three days in a covered dish in your refrigerator. To reheat, just cover with foil and warm at three hundred fifty degrees until heated through, or pop individual slices in the microwave. I find the flavor deepens even more on day two, so leftovers are a breakfast treat.
Ingredient Substitutions
If you only have plain rolls or brioche, those can substitute for croissants though the final dish will be less buttery. Any mix of berries works so use whatever looks best at the market or even a bag of frozen mixed berries. Almond extract can replace vanilla for a different twist.
Serving Suggestions
Serve the berry croissant bake warm with a light dusting of powdered sugar. Add whipped cream or a drizzle of maple syrup for extra indulgence. Pair with hot coffee and some eggs or bacon for a rounded brunch spread guests will remember.
Cultural and Family Context
This type of breakfast casserole reminds me of French and American brunch traditions entwined. It feels a little fancy thanks to the croissants yet still homey and comforting just like bread pudding my grandmother made with whatever was leftover.

This recipe earns a spot in my regular breakfast rotation especially when guests come to stay. Not only do you get a bakery worthy result with minimal effort but the flexibility with ingredients makes it perfect for every season and occasion.
Recipe Q&A
- → Can I use frozen berries instead of fresh?
Yes, frozen berries work well. Use them straight from the freezer—no need to thaw, as they will release their juices during baking.
- → What can I substitute for whole milk or heavy cream?
You can use half-and-half or any combination of milk and cream. Plant-based alternatives also work but may change the texture slightly.
- → How do I store leftovers and reheat?
Refrigerate leftovers in an airtight container for up to three days. Reheat in the oven at 300°F until warmed through or microwave portions briefly.
- → Is it possible to prepare this dish in advance?
Absolutely. Assemble everything the night before and refrigerate. In the morning, bake as directed for a fresh, warm breakfast.
- → Can I add other flavorings or toppings?
Lemon zest or almond extract add a lovely twist. Serve with whipped cream, maple syrup, or extra berries for more flavor.
