Equipment

  • 9×13-inch baking pan

Ingredients
  

Main Ingredients

  • 12–14 ounce French bread or sourdough, brioche, or challah
  • 1 cup blueberries fresh or frozen
  • 8 large eggs
  • 2.25 cups whole milk
  • 0.5 teaspoon ground cinnamon
  • ¾ cup light brown sugar packed
  • 1 Tablespoon pure vanilla extract

Streusel Topping

  • cup brown sugar packed, light or dark
  • cup all-purpose flour spooned & leveled
  • 0.5 teaspoon ground cinnamon
  • 6 Tablespoons unsalted butter cold and cubed

Instructions
 

Preparation

  • Grease a 9x13-inch pan with butter or nonstick spray. Slice, then cut the bread into cubes, about 1 inch in size. Spread cubes into the prepared baking pan and top evenly with blueberries.
  • Whisk the eggs, milk, cinnamon, brown sugar, and vanilla together until no brown sugar lumps remain. Pour over the bread. Cover the pan tightly and refrigerate for 3–24 hours. Overnight is best.
  • Preheat oven to 350°F (177°C). Remove pan from the refrigerator.
  • Prepare the topping: Whisk the brown sugar, flour, and cinnamon together in a medium bowl. Cut in the cubed butter with a pastry blender or two forks. Sprinkle the topping over the soaked bread.
  • Bake for 45–55 minutes or until golden-brown on top.
  • Serve warm. Cover leftovers tightly and store in the refrigerator for 2–3 days.

Notes

Optional: extra blueberries, maple syrup, and/or confectioners’ sugar for topping.
