Ingredients
- 1 loaf (16 ounces) Brioche bread, cubed: This buttery bread is perfect for soaking up the custard; however, feel free to use Challah or any thick, soft bread you love.
- 8 large eggs, room temperature, beaten: Room temperature eggs incorporate better, so plan ahead!
- 2 cups (490 g) whole milk, room temperature: Whole milk keeps the casserole rich and creamy.
- 1/2 cup (119 g) heavy whipping cream, room temperature: The cream adds an indulgent touch, making your casserole super luscious.
- 3/4 cup (150 g) light brown sugar, packed: You’ll love the caramel notes it adds.
- 2 teaspoons vanilla extract: Use pure vanilla extract for the best flavor.
- 1 teaspoon cinnamon: This warm spice is a classic together with bread pudding-style preparations.
- 1/2 teaspoon kosher salt: Just a pinch to balance the sweetness.
- 1/2 cup (62.5 g) all-purpose flour: This helps create the crumbly topping that you’ll sprinkle on later.
- 1/2 cup (100 g) light brown sugar, packed, for topping: Make sure it’s packed down!
- 1 teaspoon ground cinnamon, for topping: A sprinkle of this enhances flavor beautifully.
- 1/4 teaspoon kosher salt, for topping: Again, just a pinch!
- 1/2 cup (1 stick / 113 g) unsalted butter, melted, for topping: Using unsalted here will give you control over the saltiness.
- Confectioners’ sugar, for garnish: Because everything looks better with a dusting of powdered sugar!
- Pure maple syrup, for serving: Never skimp on quality syrup for real maple flavor.
Note on substitutions: You can easily swap whole milk for almond milk or oat milk for a dairy-free version, and egg alternatives are available for those avoiding eggs altogether.
Step-by-Step Instructions
Step 1: Prepare the Baking Dish
- Spray a 9×13-inch baking dish with nonstick cooking spray. Add the bread cubes to the dish in an even layer, spreading them out to avoid clumps. Set aside.
Step 2: The Egg Mixture
- In a large bowl, whisk together the eggs, milk, heavy cream, brown sugar, vanilla, cinnamon, and salt until smooth and fully combined. Pour the egg mixture evenly over the bread cubes, gently pressing down to ensure that every piece of bread gets soaked. Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or up to overnight for maximum flavor absorption.
Step 3: Prepare the Topping
- In a medium bowl, whisk together the flour, brown sugar, cinnamon, and kosher salt for the topping. Add the melted butter and mix until the mixture is crumbly and well combined. Cover the topping mixture and refrigerate until ready to bake.
Step 4: Preheat and Assemble
- When ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and sprinkle the prepared topping evenly over the soaked bread cubes.
Step 5: Bake
- Bake the casserole uncovered for 45-55 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Step 6: Serve
- Let the casserole rest for 10 minutes before serving. Dust with confectioners’ sugar and drizzle with pure maple syrup. This is where the magic happens—get ready for fresh compliments and satisfied faces!
Chef’s Tips:
- For additional flavor, try making a compote with your favorite fruits to serve on the side.
- Watch your casserole closely during the last few minutes to ensure it doesn’t over-brown.
- If you like it extra creamy, take it out a little earlier for a softer middle.
