Ingredients

Scale
  • 1 loaf (about 1 pound) thick-cut bread (brioche or challah recommended), cut into 1-inch cubes
  • 6 large eggs
  • 2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 cup granulated sugar
  • 1 tablespoon vanilla extract
  • 2 teaspoons ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 1/2 cup brown sugar, packed (for topping)
  • 2 tablespoons unsalted butter, melted (for topping)

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 eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until fully combined. This custard mixture is key for a fluffy result.
  3. Pour the custard mixture evenly over the bread cubes. Gently press down on the bread to help it absorb the liquid.
  4. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight. This step makes it an easy make-ahead breakfast.
  5. When ready to bake, preheat your oven to 350°F (175°C). Remove the plastic wrap.
  6. In a small bowl, mix the brown sugar and melted butter until crumbly. Sprinkle this topping evenly over the soaked bread.
  7. Bake for 45 to 55 minutes, or until the casserole is puffed, golden brown, and the center is set (no liquid remains when poked).
  8. Let the casserole rest for 10 minutes before slicing and serving. Serve warm with maple syrup and fresh fruit.

Notes

  • For a richer flavor, consider this recipe as part of your meal planning strategy to save time on busy mornings.
  • If you are looking for alternatives to traditional breakfast prep, this casserole is a great option that avoids the need for constant flipping like pan-fried toast.
  • This recipe pairs well with a simple keto meal plan delivery service for balanced sides if you are tracking macros.
  • If you want to try a different flavor profile, add 1 cup of fresh blueberries or sliced bananas before baking.
