With its buttery caramel base, creamy custard-soaked bread, and golden cinnamon topping, this dish is a crowd-pleaser.

Ingredients

Scale

For the Base:

  • 2 sticks butter, melted
  • 2 cups light brown sugar
  • 2 teaspoons cinnamon

For the Bread Layer:

  • 1 loaf French bread, cut into 2-inch slices

For the Custard:

  • 2 cups milk (or substitute half-and-half for richer custard)
  • 8 eggs, beaten
  • 1 teaspoon vanilla extract

Optional Toppings:

  • Powdered sugar, maple syrup, whipped cream, fresh fruit, or nuts

Instructions

Instructions:

  1. Prepare the Base:
    • Pour melted butter into an 11×15-inch baking dish, spreading it evenly. Sprinkle brown sugar and cinnamon on top to create a caramel layer.
  2. Layer the Bread:
    • Arrange slices of French bread in the dish, ensuring they are snug but not overlapping.
  3. Make the Custard:
    • Whisk together milk, beaten eggs, and vanilla extract in a mixing bowl.
  4. Assemble and Chill:
    • Pour the custard over the bread, ensuring all slices are evenly coated. Press the bread gently into the custard to help absorption. Cover with foil and refrigerate for at least 8 hours or overnight.
  5. Bake:
    • Preheat oven to 350°F (175°C). Bake the covered casserole for 30 minutes. Remove foil and bake uncovered for an additional 15 minutes, or until golden and puffed.
  6. Serve:
    • Let cool for 5 minutes before slicing. Serve warm with toppings of your choice.

Notes

  • For added crunch, sprinkle chopped pecans or walnuts over the brown sugar base before adding the bread.
  • For a seasonal twist, layer fresh berries, bananas, or sliced apples between the bread slices.
  • Leftovers can be stored in the refrigerator for 3–4 days or frozen for up to 2 months.
