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 the Croissants

Preheat your oven to 350 degrees F.
* Add the cubed croissants in a single layer to a large baking sheet (15×21 inches).
* Bake for about 7-10 minutes until golden and very toasted. Keep an eye on them so they don’t burn!
* Set aside to cool.

Step 2: Prepare the Custard

In a large mixing bowl:
1. Add the softened cream cheese and granulated sugar.
2. Beat with a hand mixer until smooth.
3. Beat in the eggs until fully integrated.
4. Gradually mix in half and half, followed by lemon juice, lemon zest, vanilla extract, and salt.

Step 3: Assemble the Casserole

In a lightly greased 9×13 baking dish:
1. Transfer half of the toasted croissant cubes into the dish.
2. Evenly layer with half of the mixed berries.
3. Pour half of the custard over this layer.
4. Add remaining croissant cubes in a single layer followed by remaining custard.
5. Press down gently so most croissants are submerged in custard; it’s okay if some tops remain above.
6. Scatter remaining berries over the top.
7. Cover with foil and refrigerate overnight.

Step 4: Bake the Casserole

When ready to bake:
1. Remove casserole from refrigerator and let it sit on counter while preheating oven to 350 degrees F.
2. Bake covered with foil for 30 minutes.
3. Remove foil and bake uncovered for an additional 15 minutes or until a knife inserted in center comes out clean.

Step 5: Make the Lemon Glaze

While casserole is baking:
1. In a medium mixing bowl, combine all glaze ingredients.
2. Beat with hand mixer until smooth.
3. Taste and adjust sweetness with more powdered sugar or add lemon juice for extra tanginess.

Step 6: Serve Warm

Serve your Sweet Breakfast Casserole warm from the oven! Allow individuals to dust their servings with powdered sugar if desired for added sweetness.

Enjoy this delightful dish that combines simplicity with deliciousness!

Common Mistakes to Avoid

  • Ignoring ingredient temperatures: Ensure eggs and half-and-half are at room temperature before mixing. This helps create a smoother custard mixture.
  • Forgetting to press down the croissants: Pressing down ensures that most of the croissants soak up the custard, providing better flavor throughout.
