Ingredients You’ll Need

For the Croissant Casserole

For the Macerated Berries

Step-by-Step Instructions

Prepare Your Baking Dish

1. Generously butter a 9×13-inch (3-quart) baking dish using softened butter
2. Place the prepared dish on a rimmed baking sheet to catch any potential drips during baking
3. Set aside while you prepare the fillings

Make the Cream Cheese Filling

4. In a medium mixing bowl, combine 8 ounces room temperature cream cheese, 2 tablespoons powdered sugar, and 1/4 teaspoon vanilla extract
5. Using an electric mixer or whisk, beat until completely smooth and no lumps remain
6. Set this mixture aside while you prepare the custard

Prepare the Custard Base

7. 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
8. Whisk vigorously using kitchen utensils until the mixture is well combined and slightly frothy
9. This custard will soak into the croissants and create that signature creamy texture

Cut and Layer the Croissants

10. Using a serrated knife, halve 12 mini croissants crosswise and set the top halves aside
11. Cut the bottom halves and remaining 12 croissants into 1-2 inch pieces (you should have about 12 cups total)
12. Arrange two-thirds of the cut croissant pieces (about 8 cups) in an even layer in your prepared baking dish
13. Dollop the cream cheese mixture and lemon curd randomly over the croissant pieces for pockets of creamy tanginess
14. Top evenly with remaining croissant pieces, allowing some cream cheese and lemon curd to peek through

Soak and Assemble

15. Pour about half of the egg custard mixture evenly over the croissant layers
16. Take the reserved croissant tops and dip each one briefly in the remaining custard until just saturated
17. Arrange these soaked tops, cut sides down, in an even layer over the casserole
18. Pour any remaining custard mixture over the entire dish
19. 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

20. While the casserole rests, add 1/2 cup blueberries and 1/2 cup blackberries to a medium bowl
21. Using a potato masher or fork, thoroughly mash these berries to release their juices
22. Stir in 3 tablespoons sugar, 1 1/2 teaspoons lemon juice, and the remaining berries
23. Let this mixture stand at room temperature for at least 1 hour, stirring occasionally

Bake to Perfection

24. Preheat your oven to 350°F
25. Bake the covered casserole for 45 minutes
26. Remove the foil and continue baking for 15-30 minutes more until golden brown, set, and cooked through
27. The top should be crispy and golden while the interior remains custardy

Serve and Enjoy

28. Dust the top generously with powdered sugar using a fine-mesh sieve
29. Top with a generous portion of the macerated berries
30. 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.
