Ingredients
INGREDIENTS
- 1 loaf brioche bread, cut into cubes
- 1 cup raisins
- 6 large eggs
- 2 cups whole milk
- 1/2 cup heavy cream
- 1/2 cup granulated sugar
- 1 tablespoon vanilla extract
- 1 tablespoon ground cinnamon
- 1/4 teaspoon nutmeg
- 1/4 teaspoon salt
- 2 tablespoons unsalted butter, melted
- Powdered sugar for serving
- Maple syrup for serving
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter or cooking spray.
- In a large bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
- Add the cubed brioche bread and raisins to the egg mixture, gently folding to ensure all the bread is soaked in the custard.
- Pour the mixture into the prepared baking dish, spreading it out evenly. Drizzle the melted butter over the top.
- Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight to allow the bread to soak up the custard.
- Once ready to bake, remove the casserole from the fridge and let it sit at room temperature for about 15 minutes while preheating the oven.
- Bake uncovered for 40-45 minutes, or until the top is golden brown and a knife inserted in the center comes out clean.
- Let the casserole cool for 5-10 minutes before serving. Dust with powdered sugar and serve warm with maple syrup. Enjoy!
Notes
Tip: This casserole can be prepared the night before, making it perfect for brunch gatherings!
To make this casserole even more special, consider adding chopped nuts or fresh fruit like berries or bananas to the mixture before baking. If you prefer a less sweet version, decrease the amount of sugar in the custard. Leftovers can be stored in the refrigerator and reheated in the oven or microwave for a quick breakfast. Just reheat until warmed through, and enjoy!
