How to Make Croissant Breakfast Casserole with Lemon Curd and Berries Recipe
Step 1: Prepare the Baking Dish and Croissants
First, preheat your oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish to prevent sticking. Tear your croissants into chunks about the size of a bite so they layer beautifully. Arrange all the croissant chunks evenly in the baking dish, allowing the buttery flakiness to shine through in every bite.
Step 2: Add the Berries
Scatter the mixed berries evenly over the croissant chunks. Whether you use fresh or frozen, these berries will offer natural sweetness and a juicy texture that contrasts perfectly with the rich custard. The berries’ vibrant reds, blues, and purples also make this dish look beautiful and inviting.
Step 3: Whisk Together the Custard
In a medium bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, and lemon zest. This smooth mixture will soak into the croissants, ensuring each bite is tender and bursting with flavor. The lemon zest especially adds a subtle zing that makes the custard taste unforgettable.
Step 4: Layer with Lemon Curd and Pour Custard
Drizzle the lemon curd evenly over the croissants and berries. This is the star ingredient that adds a luscious lemon punch to every bite. Then pour the egg mixture gently and evenly over everything. Use a spatula or your hands to press down lightly so the croissants soak up that custard goodness completely.
Step 5: Let it Rest and Bake
Let the casserole sit at room temperature for 10 to 15 minutes to allow the custard to absorb fully. For an even better flavor and texture, you can refrigerate it overnight as a make-ahead option. When you’re ready, bake it uncovered for 35 to 40 minutes until the top is golden brown and the custard is completely set. Allow it to cool slightly before serving.
How to Serve Croissant Breakfast Casserole with Lemon Curd and Berries Recipe

Garnishes
Dusting the casserole with powdered sugar just before serving adds a lovely visual touch and a touch of sweet elegance. You can also swirl a little extra lemon curd on top for an extra pop of citrus brightness that guests will adore.
Side Dishes
Serve this casserole alongside a crisp green salad or a platter of fresh fruit for a balanced brunch. A dollop of whipped cream or a scoop of Greek yogurt can bring an extra creamy element that complements the tangy lemon and sweet berries beautifully.
Creative Ways to Present
For a stunning presentation, bake the casserole in individual ramekins for personalized servings at your breakfast table. You might also layer it with a mix of seasonal fruits, such as stone fruits in summer, for a fresh twist that celebrates the flavors of the season.
Make Ahead and Storage
Storing Leftovers
Store any leftovers tightly covered in the refrigerator for up to 3 days. The casserole holds its flavor wonderfully and can be enjoyed cold or warmed up again for another delicious breakfast.
Freezing
This Croissant Breakfast Casserole with Lemon Curd and Berries Recipe freezes well. Wrap the entire casserole or individual portions in plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat leftovers in a 350°F oven for 10-15 minutes or until warmed through. Alternatively, microwave individual portions for about 1-2 minutes, though the oven method keeps the texture more enjoyable.
FAQs
Can I use other breads instead of croissants?
Absolutely! While croissants impart a buttery, flaky richness, you can swap in brioche or challah for a similar tender texture and sweetness. Just make sure the bread is slightly stale to absorb the custard well.
Is it okay to use frozen berries?
Yes, frozen berries are a convenient option and work just as well in this recipe. No need to thaw them before baking, but adding fresh berries on top after baking can boost flavor and freshness.
Can I make this recipe vegan or dairy-free?
You can adapt it by using plant-based milk and cream alternatives, vegan butter croissants, and an egg substitute like a flaxseed or chia mixture. The lemon curd might be trickier, but there are vegan lemon curd recipes or store-bought versions you can try.
How far in advance can I prepare this casserole?
You can assemble it the night before and refrigerate it overnight for a quick morning bake. This also helps the croissant chunks soak up the custard for a more custardy texture.
What is the best way to get a crispy top?
To get a golden, slightly crisp top, bake uncovered at the recommended temperature. If you want an extra crisp top, you can broil for 1-2 minutes at the end, but watch closely to avoid burning.
