Freshly baked French Toast Casserole with cinnamon topping in baking dish
Print Recipe

This cozy French Toast Casserole soaks overnight, then bakes into a soft, cinnamon-scented breakfast with a buttery brown sugar topping.

Ingredients

Scale
  • 1 loaf French bread, or thick Texas toast
  • 8 eggs
  • 2 cups half and half
  • 1/2 cup milk
  • 3 Tbsp granulated sugar
  • 1 1/2 teaspoons pure vanilla extract
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 1 1/2 sticks butter, softened
  • 1 cup packed light brown sugar
  • 1 Tbsp light corn syrup, optional
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg

Instructions

  1. Grease a 9×13 baking dish with butter or cooking spray.
  2. Cut the French bread into slices about 1 inch thick, then arrange them in overlapping rows inside the dish.
  3. Whisk the eggs in a large bowl until smooth.
  4. Add the half and half, milk, granulated sugar, vanilla extract, 1/2 teaspoon cinnamon, 1/2 teaspoon nutmeg, and salt. Whisk until everything is blended.
  5. Pour the custard over the bread, spooning it between the slices so each piece is well coated.
  6. Cover the dish with foil and refrigerate overnight.
  7. The next day, heat the oven to 350°F.
  8. Gently turn each bread slice over so both sides are soaked with the custard.
  9. In a medium bowl, stir together the softened butter, brown sugar, corn syrup, 1 teaspoon cinnamon, and 1/2 teaspoon nutmeg.
  10. Spoon the topping over the bread and spread it across the slices. Add a little between the slices if desired.
  11. Bake uncovered for 35-40 minutes, until puffed and lightly golden.

Notes

  • The center will be soft and custardy, while the top bakes with a lightly crisp finish.
  • For more crisp edges, use a larger baking pan or divide the recipe between two 9×13 pans.
  • Sliced sourdough from the bakery can be used to save prep time.
  • If you miss the overnight chill, soak the slices very well before baking.
