Step-by-Step Instructions
Prepare Your Baking Dish
- Generously butter a 9×13-inch (3-quart) baking dish using softened butter
- Place the prepared dish on a rimmed baking sheet to catch any potential drips during baking
- Set aside while you prepare the fillings
Make the Cream Cheese Filling
- In a medium mixing bowl, combine 8 ounces room temperature cream cheese, 2 tablespoons powdered sugar, and 1/4 teaspoon vanilla extract
- Using an electric mixer or whisk, beat until completely smooth and no lumps remain
- Set this mixture aside while you prepare the custard
Prepare the Custard Base
- In a large mixing bowl, whisk together 8 eggs, 2 cups whole milk, 2/3 cup granulated sugar, 4 tablespoons melted butter, lemon zest, cardamom, salt, and remaining 2 teaspoons vanilla
- Whisk vigorously using kitchen utensils until the mixture is well combined and slightly frothy
- This custard will soak into the croissants and create that signature creamy texture
Cut and Layer the Croissants
- Using a serrated knife, halve 12 mini croissants crosswise and set the top halves aside
- Cut the bottom halves and remaining 12 croissants into 1-2 inch pieces (you should have about 12 cups total)
- Arrange two-thirds of the cut croissant pieces (about 8 cups) in an even layer in your prepared baking dish
- Dollop the cream cheese mixture and lemon curd randomly over the croissant pieces for pockets of creamy tanginess
- Top evenly with remaining croissant pieces, allowing some cream cheese and lemon curd to peek through
Soak and Assemble
- Pour about half of the egg custard mixture evenly over the croissant layers
- Take the reserved croissant tops and dip each one briefly in the remaining custard until just saturated
- Arrange these soaked tops, cut sides down, in an even layer over the casserole
- Pour any remaining custard mixture over the entire dish
- Cover tightly with aluminum foil and let stand at room temperature for 1 hour to allow the croissants to absorb the custard
Prepare the Macerated Berries
- While the casserole rests, add 1/2 cup blueberries and 1/2 cup blackberries to a medium bowl
- Using a potato masher or fork, thoroughly mash these berries to release their juices
- Stir in 3 tablespoons sugar, 1 1/2 teaspoons lemon juice, and the remaining berries
- Let this mixture stand at room temperature for at least 1 hour, stirring occasionally
Bake to Perfection
- Preheat your oven to 350°F
- Bake the covered casserole for 45 minutes
- Remove the foil and continue baking for 15-30 minutes more until golden brown, set, and cooked through
- The top should be crispy and golden while the interior remains custardy
Serve and Enjoy
- Dust the top generously with powdered sugar using a fine-mesh sieve
- Top with a generous portion of the macerated berries
- Serve immediately while warm, passing extra berries at the table

Pro Tips for Perfect Results
Use Day-Old Croissants: Slightly stale croissants absorb the custard better without becoming mushy. Fresh croissants can become too soggy.
Don’t Skip the Resting Time: Allowing the casserole to stand for an hour ensures even custard distribution and prevents dry spots.
Watch the Baking Time: Ovens vary, so check your casserole at the 15-minute mark after uncovering. The center should be set but still slightly jiggly.
Make It Ahead: Assemble the casserole the night before, cover, and refrigerate. Add 10-15 minutes to the covered baking time if baking straight from the fridge.
Customize Your Berries: Raspberries, strawberries, or a combination of all four berries work beautifully in this recipe.
Storage and Reheating
Store leftover croissant casserole covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 45-60 seconds or warm the entire dish covered in a 300°F oven for 15-20 minutes. The texture is best when served fresh, but leftovers still taste delicious.
Frequently Asked Questions
Can I use different types of croissants?
Absolutely! Plain butter croissants work best, but chocolate or almond croissants can add interesting flavor variations. Avoid savory croissants for this sweet recipe.
What can I substitute for lemon curd?
Try raspberry jam, orange marmalade, or even Nutella for different flavor profiles. Apple butter also works wonderfully for fall-inspired versions.
Is cardamom essential?
While cardamom adds a unique aromatic quality, you can substitute with cinnamon, nutmeg, or omit the spice entirely for a simpler flavor profile.
Can I make this dairy-free?
Use dairy-free cream cheese, plant-based milk, and vegan butter substitutes. The texture will be slightly different but still delicious.
How do I know when it’s fully cooked?
The center should be set and not jiggly, and an instant-read thermometer inserted in the center should read 160°F.
Can I freeze this casserole?
Yes! Freeze unbaked casserole tightly wrapped for up to 2 months. Thaw overnight in the refrigerator before baking as directed, adding 10-15 minutes to covered baking time.
