A decadent baked French toast casserole with a rich custard interior and a caramelized topping inspired by crème brûlée. Perfect for holiday brunches or weekend indulgence.
1 loaf brioche or challah bread, sliced 1-inch thick
1/2 cup unsalted butter
1 cup dark brown sugar
2 tablespoons light corn syrup
5 large eggs
1 1/2 cups whole milk
1/2 cup heavy cream
2 teaspoons pure vanilla extract
1/4 teaspoon salt
In a saucepan, melt the butter. Stir in brown sugar and corn syrup until smooth.
Pour the mixture into a greased 9×13-inch baking dish.
Layer the bread slices over the caramel in a snug arrangement.
In a bowl, whisk together eggs, milk, cream, vanilla, and salt.
Pour custard over the bread. Press gently to absorb.
Cover and refrigerate overnight.
Preheat oven to 350°F. Let the casserole sit at room temp for 30 minutes.
Bake covered for 30 minutes, then uncover and bake 15–20 more until golden.
Cool slightly, then invert onto a serving platter.
Use slightly stale bread for best texture.
Add cinnamon or orange zest for extra flavor.
Serve with berries or whipped cream.
Store leftovers refrigerated for up to 4 days.
