Ingredients
Base
- 1 (24-ounce) loaf sourdough bread (or brioche, challah, or French bread), cut into 1-inch cubes
- 8 large eggs
- 2 cups milk
- ½ cup heavy cream
- 1 tablespoon vanilla extract
- ¾ cup sugar
Topping
- ½ cup all-purpose flour
- ½ cup packed light brown sugar
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup cold unsalted butter, cut into pieces
Instructions
- Prepare the Bread: Cut the bread into 1-inch cubes and scatter them evenly in a greased 9-x-13-inch baking dish to create the base layer.
- Make the Custard: In a medium bowl, whisk together the eggs, milk, heavy cream, vanilla extract, and sugar until thoroughly combined. Pour this mixture evenly over the bread cubes, ensuring all pieces are soaked.
- Chill Overnight: Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours or preferably overnight to allow the bread to soak up the custard fully.
- Prepare the Topping: In another bowl, mix together the flour, brown sugar, cinnamon, and salt. Cut the cold butter into this dry mixture using a pastry cutter or fingers until the texture becomes crumbly. Transfer the topping to a small resealable plastic bag and refrigerate overnight.
- Preheat Oven: When ready to bake, remove the casserole and topping from the refrigerator, and preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
- Add Topping: Unwrap the baking dish and evenly sprinkle the prepared crumbly topping over the soaked bread custard.
- Bake: Place the casserole uncovered in the oven and bake for 45-60 minutes. Baking time depends on your preferred softness; towards the shorter time for a softer custard, longer for a firmer set and golden topping.
Notes
- Using sourdough imparts a slight tang, but brioche or challah will offer a richer, sweeter base.
- Make sure the butter is cold when cutting it into the topping to achieve a crumbly texture.
- The soaking time can be extended overnight for best results; the bread will absorb more custard and improve texture.
- For a dairy-free version, substitute milk and cream with plant-based alternatives.
- Serve warm with maple syrup or fresh fruits for an extra special touch.
- Leftovers can be refrigerated and reheated gently in the oven or microwave.
