Ingredients

Scale

Custard Mixture

10 small eggs
2 cups milk
1/2 cup whipping cream
1/2 cup granulated sugar
2 teaspoons vanilla extract

Base

18 ounces sourdough bread

Crumble Topping

1/2 cup all-purpose flour
1/2 cup brown sugar
1 1/2 teaspoons pumpkin pie spice
1/4 teaspoon salt
1/2 cup butter, grated

Instructions

Prepare the custard: In a bowl, whisk together 10 small eggs, 2 cups milk, 1/2 cup whipping cream, 1/2 cup granulated sugar, and 2 teaspoons vanilla extract until fully combined and smooth.
Assemble the base: Grease a 9”x13” baking dish evenly and arrange 18 ounces of sourdough bread in a single, even layer. Pour the prepared egg mixture evenly over the bread, gently pressing the bread down so it absorbs the custard.
Make the crumble topping: In a separate bowl, mix 1/2 cup all-purpose flour, 1/2 cup brown sugar, 1 1/2 teaspoons pumpkin pie spice, and 1/4 teaspoon salt. Grate 1/2 cup cold butter into the mixture, then use your fingers or a pastry cutter to combine until it forms a crumbly texture.
Refrigerate overnight: Cover the baking dish and the bowl with the crumble topping separately with plastic wrap and refrigerate both overnight to allow the custard to soak into the bread.
Preheat and finish assembly: The next day, remove the baking dish and crumble from the refrigerator while preheating the oven to 350°F (180°C). Evenly sprinkle the crumble topping over the soaked bread base.
Bake the casserole: Bake in the preheated oven for 45 to 50 minutes, or until the casserole is golden brown on top and fully set in the center.
Serve: Serve warm with your choice of toppings such as maple syrup, fresh berries, whipped cream, chocolate drizzle, or sprinkles for an indulgent breakfast or brunch.

Notes

Be sure to refrigerate the assembled dish overnight to allow the bread to fully soak up the custard for the best texture.
Using day-old or slightly stale sourdough bread helps it soak up the custard without becoming too mushy.
The crumble topping can be prepared ahead and kept in the fridge separately until ready to use.
For a dairy-free version, substitute milk and cream with your preferred plant-based alternatives and use vegan butter.
Adjust baking time if using a different sized pan; the casserole should be set and golden but not dry.
