Ingredients You’ll Need
Simple ingredients come together beautifully in this recipe, each playing a crucial role in flavor, texture, and visual appeal. From the tender croissant base to the fresh berries that add juicy pops of sweetness, every component is essential to the harmony of the dish.
- 4 large croissants, cut into chunks: The buttery, flaky foundation that soaks up the custard mixture perfectly.
- 1/2 cup lemon curd: Adds a bright, citrusy zing that balances the richness of the custard.
- 2 cups mixed fresh berries: Use blueberries, raspberries, strawberries, or a combination for colorful, juicy bursts.
- 4 large eggs: The protein that binds the casserole and creates a creamy custard texture.
- 1 cup whole milk: Adds moisture and helps the custard set just right.
- 1/2 cup heavy cream: Contributes to a rich, velvety finish.
- 1/4 cup granulated sugar: Sweetens the custard without overpowering the tart lemon.
- 1 tsp vanilla extract: Infuses the custard with warm, aromatic notes.
- 1/2 tsp ground cinnamon: Adds subtle spice that complements the berries beautifully.
- 1/4 tsp salt: Enhances all the flavors and balances the sweetness.
- Powdered sugar (for dusting, optional): A final touch for a pretty presentation and extra sweetness.
How to Make Croissant Breakfast Casserole with Lemon Curd and Berries Recipe
Step 1: Prepare Your Croissants and Berries
Start by cutting your croissants into bite-sized chunks and placing them in a greased baking dish. Scatter half of your mixed fresh berries evenly over the croissant pieces to ensure every bite has a juicy, fruity surprise.
Step 2: Spread Lemon Curd
Dollop spoonfuls of lemon curd across the croissants and berries. The lemon curd will melt into the custard as it bakes, giving the casserole a lovely burst of citrus flavor that cuts through the richness.
Step 3: Whisk the Custard Mixture
In a large bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until the mixture is smooth and slightly frothy. This custard base is the heart of the dish, creating a lusciously creamy texture.
Step 4: Pour Custard Over the Croissant Mixture
Carefully pour the custard evenly over the croissants, lemon curd, and berries, pressing down gently with a spatula to soak all the bread pieces. Let it sit for about 10 minutes if you have time — this helps the croissants absorb the custard fully.
Step 5: Add Remaining Berries and Bake
Sprinkle the rest of your fresh berries on top for an attractive finish. Bake the casserole in a preheated oven at 350°F (175°C) for 35 minutes, or until the custard is set and the top is golden brown. The aroma alone is enough to make you eager for breakfast!
How to Serve Croissant Breakfast Casserole with Lemon Curd and Berries Recipe

Garnishes
A light dusting of powdered sugar adds a touch of sweetness and makes the casserole look absolutely irresistible. Fresh mint leaves or a small spoonful of extra lemon curd on top can also add vibrant color and flavor contrast.
Side Dishes
Pair this casserole with crisp bacon or sausage for a savory balance. A simple green salad with a citrus vinaigrette works surprisingly well to lighten the meal and complement the tartness of the lemon curd.
Creative Ways to Present
For a brunch party, serve this casserole in individual ramekins for elegant portions. You can also add a drizzle of honey or a swirl of whipped cream just before serving to delight your guests even more.
Make Ahead and Storage
Storing Leftovers
Place leftover casserole in an airtight container and refrigerate for up to 3 days. The flavors deepen nicely, though the berries may become slightly softer which adds to the cozy texture.
Freezing
This casserole freezes well before baking. Assemble in a freezer-safe dish, cover tightly, and freeze for up to one month. Thaw overnight in the fridge before baking as directed.
Reheating
Reheat leftovers gently in the oven at 325°F (160°C) for 10-15 minutes or until warmed through to revive the fresh-baked goodness. Microwaving is possible but may soften the pastry more.
FAQs
Can I use day-old croissants for this recipe?
Absolutely! Day-old croissants are actually ideal because they soak up the custard better without turning mushy, leading to a perfectly textured casserole.
What kind of berries work best?
Mixed fresh berries like blueberries, raspberries, and strawberries provide a lovely range of flavors and colors. You can use frozen berries as a substitute, but fresh is best for texture.
Is lemon curd necessary, or can I substitute?
Lemon curd is key to this recipe’s signature tangy flavor. If you can’t find any, homemade lemon curd or a lemon glaze can work, but it’s worth seeking out the real deal to get that bright punch.
Can I make this recipe dairy-free?
Yes! Swap the whole milk and heavy cream for your favorite plant-based milks and creamers. Use dairy-free butter or margarine croissants if available. The texture will be slightly different but still delicious.
How far in advance can I assemble this casserole?
You can prep the casserole the night before, cover it tightly, and refrigerate. Then bake it fresh in the morning for a stress-free start to the day.
