Instructions

1
In a large bowl, whisk together eggs, milk, heavy cream, granulated sugar, and vanilla extract until well combined.
2
Place the cubed bread in a greased 13x9 inch baking dish.
3
Pour the egg mixture evenly over the bread. Lightly press the bread down to ensure all pieces are soaked.
4
In a separate bowl, prepare the topping by mixing together the flour, brown sugar, cinnamon, and salt.
5
Grate the cold butter into the topping mixture and use a fork to combine until it forms a crumbly texture.
6
Cover both the baking dish and the bowl of topping, and refrigerate overnight.
7
The next day, preheat your oven to 350°F (175°C). Remove both dishes from the refrigerator.
8
Evenly sprinkle the crumble topping over the soaked bread.
9
Bake for 45-50 minutes, or until the casserole is golden brown and the center is set.
10
Let it cool slightly before serving. Serve warm with your favorite toppings like maple syrup, whipped cream, and fresh berries.

Tips & Notes

Pro tips

Cut bread into uniform 1-inch cubes so they absorb custard evenly without breaking apart.
Let the assembled casserole sit in the refrigerator for at least 4 hours (or overnight) so the bread fully absorbs the custard mixture.
The crumb topping will brown faster than the custard sets; tent with foil if browning too quickly, then uncover in the final 10 minutes for color.
Test doneness by inserting a knife near the center—it should come out clean or with just a slight wet crumb, not runny custard.

Substitutions

Whole milk → milk (reduces richness and fat content)
Granulated sugar → maple syrup (use 3/4 cup; reduces other liquids by 2 tablespoons)
All-purpose flour in topping → rolled oats (adds texture; use same amount)
