Description

A sweet and comforting make-ahead breakfast casserole made with fluffy bread soaked in rich custard and topped with a buttery cinnamon streusel. Perfect for holidays, brunch gatherings, or a cozy weekend morning.


Ingredients

1 loaf French bread or brioche, cut into cubes (about 1012 cups)

8 large eggs

2 cups whole milk (or half-and-half)

1/2 cup heavy cream

1/3 cup granulated sugar

1/3 cup brown sugar

2 teaspoons vanilla extract

1 teaspoon ground cinnamon

1/4 teaspoon salt

1/2 cup all-purpose flour

1/2 cup brown sugar (for streusel)

1 teaspoon cinnamon (for streusel)

1/4 teaspoon salt (for streusel)

1/2 cup cold unsalted butter, cubed


Instructions

  1. Grease a 9x13-inch baking dish and spread the cubed bread evenly inside.
  2. In a large bowl, whisk together eggs, milk, cream, both sugars, vanilla, cinnamon, and salt.
  3. Pour the custard mixture evenly over the bread in the baking dish.
  4. Cover the dish tightly and refrigerate overnight or for at least 4 hours.
  5. In a bowl, combine flour, brown sugar, cinnamon, and salt for the streusel topping.
  6. Cut in the cold butter using a fork or pastry cutter until the mixture is crumbly. Refrigerate until ready to bake.
  7. Preheat the oven to 350°F (175°C).
  8. Sprinkle the cold streusel topping evenly over the soaked bread.
  9. Bake uncovered for 45–55 minutes until golden brown and set in the center.
  10. Serve warm with maple syrup, powdered sugar, or fresh berries.

Notes

Add blueberries or raspberries for a fruity twist.

Include chopped pecans or walnuts in the streusel for crunch.

Try pumpkin pie spice and canned pumpkin for a fall variation.

Use mini chocolate chips between layers for a more dessert-like version.

Substitute gluten-free bread for a gluten-free option.

Store leftovers in the fridge up to 4 days or freeze up to 2 months.

Reheat individual portions in the microwave or larger portions in the oven at 325°F.
