Ingredients
For the Casserole
- 8 large croissants, sliced into 1-inch cubes (10 packed cups)
- 4 cups mixed berries, (raspberries, blackberries, blueberries)
- 14 ounces cream cheese, softened
- 1 1/4 cup granulated sugar
- 6 eggs, at room temperature
- 2 cups half and half, at room temperature
- 1 tablespoon vanilla extract
- 1 tablespoon lemon juice
- 2 teaspoons lemon zest
- 1/4 teaspoon salt
For the Lemon Glaze
- 2 ounces cream cheese, softened
- 1 cup powdered sugar, sifted
- 1 ½ tablespoons lemon juice
- 1 1/2 teaspoons vanilla extract
How to Make Sweet Breakfast Casserole (with Croissants)
Step 1: Toast Croissants
Preheat your oven to 350 degrees F. Add the cubed croissants in a single layer on a large baking sheet. Bake at 350 degrees F for about 7-10 minutes until golden brown and very toasted. Keep an eye on them so they don’t burn! Afterward, set them aside to cool.
Step 2: Prepare Custard Mixture
In a large mixing bowl, combine cream cheese and granulated sugar. Beat with a hand mixer until smooth. Then add in the eggs one at a time, mixing well after each addition. Follow with half and half, then mix in lemon juice, lemon zest, vanilla extract, and salt until fully combined.
Step 3: Assemble Casserole Layers
Transfer half of the toasted croissant cubes into a lightly greased 9×13 baking dish. Evenly distribute half of the mixed berries over this layer. Pour half of the custard mixture across these layers. Repeat by adding remaining croissants followed by remaining custard. Press down gently so most of the croissants are submerged in custard; it’s okay if some tops remain above. Scatter leftover berries on top, cover with foil, and refrigerate overnight.
Step 4: Bake Casserole
When you’re ready to bake, take out the casserole from the refrigerator and let it sit while preheating your oven to 350 degrees F. Bake covered with foil for about 30 minutes. Remove foil and bake uncovered for an additional 15 minutes or until a knife inserted into the center comes out clean.
Step 5: Make Lemon Glaze
While baking, prepare your lemon glaze by adding all glaze ingredients into a medium mixing bowl. Beat with a hand mixer until smooth; taste test and add more sugar for sweetness or lemon juice for tanginess as desired.
Step 6: Serve Your Casserole
Serve this delightful breakfast casserole warm from the oven. Allow guests to dust their portions with powdered sugar if sweeter servings are preferred.

Common Mistakes to Avoid
Avoiding common mistakes can ensure your Sweet Breakfast Casserole (with Croissants) turns out perfectly every time.
- Skipping the Cooling Step: Not letting the toasted croissants cool can lead to a soggy casserole. Always allow them to cool before mixing with the custard.
- Using Cold Ingredients: Cold eggs and half-and-half can lead to a lumpy custard. Make sure all ingredients are at room temperature for a smooth mixture.
- Overmixing the Custard: Overmixing can incorporate too much air, resulting in a less creamy texture. Mix until just combined for the best results.
- Not Pressing Down the Croissants: Failing to press down on the croissants after assembling might leave them floating on top. Ensure they are submerged in the custard for even soaking.
- Ignoring Refrigeration Time: Skipping overnight refrigeration can affect flavor and texture. Allow at least 8 hours for optimal results.
- Serving Without Glaze: Forgetting the glaze means missing out on extra flavor. Drizzle it generously over each serving for a delightful finish.
