Prepare this rich, custardy French toast casserole the night before for an easy, impressive breakfast or brunch the next morning. It features warm cinnamon flavor and a simple streusel topping.

Ingredients

Scale
  • 1 loaf (about 1 pound) sturdy bread like Brioche or Challah, cut into 1-inch cubes
  • 12 large eggs
  • 3 cups whole milk or half-and-half
  • 1 cup granulated sugar
  • 1 tablespoon vanilla extract
  • 2 teaspoons ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, melted (for custard)
  • 1/2 cup packed brown sugar (for streusel)
  • 1/2 cup all-purpose flour (for streusel)
  • 1/2 cup old-fashioned rolled oats (for streusel)
  • 1/2 cup (1 stick) cold unsalted butter, cut into small pieces (for streusel)

Instructions

  1. Grease a 9×13 inch baking dish. Arrange the bread cubes evenly in the prepared dish.
  2. In a large bowl, whisk together the 12 eggs, milk, granulated sugar, vanilla extract, cinnamon, nutmeg, salt, and 1/2 cup melted butter until fully combined. This is your custard mixture.
  3. Pour the custard mixture slowly and evenly over the bread cubes, pressing down gently to help the bread absorb the liquid.
  4. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight.
  5. When ready to bake, preheat your oven to 350°F (175°C). Remove the plastic wrap.
  6. Prepare the streusel topping: In a separate bowl, combine the brown sugar, flour, and oats. Cut in the 1/2 cup cold butter pieces using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  7. Sprinkle the streusel topping evenly over the soaked bread.
  8. Bake for 45 to 55 minutes, or until the casserole is puffed, golden brown, and the center is set (a knife inserted near the center comes out mostly clean).
  9. Let the casserole rest for 10 minutes before slicing and serving. Serve warm with maple syrup.

Notes

  • For a make-ahead option, prepare the entire casserole, including the streusel topping, the night before. Keep it covered in the refrigerator. Add 5-10 minutes to the baking time if baking directly from the fridge.
  • If you are planning your weekly meals, this recipe works well alongside a simple meal planning approach for busy mornings.
  • If you want a richer flavor, substitute half the milk with heavy cream.
