Description
An elegant breakfast casserole made with flaky croissants, savory custard, ham rosettes, and Gruyère cheese, finished with aromatic garlic-herb butter.
Ingredients
- 8 croissants (about 22 ounces)
- 6 large eggs
- 1½ cups half-and-half
- 4 ounces Gruyère cheese, divided (3 ounces sliced, 1 ounce grated)
- 6 slices deli ham (about 5 ounces)
- 2 teaspoons Dijon mustard
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- Cooking spray
- 2 tablespoons unsalted butter, melted
- 1 small garlic clove, grated
- 2 teaspoons finely chopped fresh herbs (chives, rosemary, thyme, or a combination)
- 1 pinch kosher salt
Instructions
- Preheat your oven to 350°F. Lightly coat a 9×13-inch baking dish with cooking spray.
- Cut 3 ounces of Gruyère cheese into thin slices and grate the remaining 1 ounce.
- Whisk together the eggs, half-and-half, Dijon mustard, kosher salt, and black pepper until smooth.
- Cut each croissant crosswise into 3 pieces. Dip each piece in the custard mixture and arrange them tightly in the baking dish.
- Pour any remaining custard over the croissant pieces.
- Halve the ham slices, fold, and roll into rosettes. Place them between the croissant pieces.
- Tuck sliced Gruyère between croissant pieces and sprinkle grated Gruyère on top.
- Bake for 40-45 minutes until the center is set and croissant tops are golden brown.
- In a bowl, stir together melted butter, grated garlic, chopped herbs, and a pinch of salt.
- Brush the garlic-herb butter over the hot casserole immediately after baking. Let it rest for 5 minutes before serving.
