Blueberry French toast casserole is the best brunch recipe! It’s topped with a crunchy streusel topping and homemade blueberry syrup.


  • 1 loaf unsliced sourdough or French bread (about 1 pound), cut into cubes
  • 1 cup blueberries
  • 8 eggs
  • 1 3/4 cups 2% milk
  • 3/4 cup heavy cream
  • 6 tablespoons light brown sugar
  • 1 tablespoon vanilla extract
  • ½ tablespoon + 1 teaspoon cinnamon, divided
  • ½ teaspoon nutmeg
  • ¼ teaspoon kosher salt
  • ¼ cup rolled oats
  • ¼ cup crushed pecans
  • ¼ cup turbinado or demerara sugar*
  • 2 tablespoons all-purpose flour
  • 6 tablespoons salted butter, cold and cut into small pieces
  • 1 recipe Blueberry Syrup* (required!)


  1. Preheat oven to 375°F.
  2. Grease a 9 x 13″ baking dish. Add half the torn bread to the dish then 1/2 cup of the blueberries, then more bread.
  3. In a large bowl, whisk the eggs until fully incorporated and frothy. Whisk in the milk, cream, sugar, vanilla extract, ½ tablespoon cinnamon, nutmeg and kosher salt. Pour the custard over the bread pieces and use your fingers to submerge the tops of the bread to ensure it is all coated. Top with the remaining 1/2 cup blueberries. Rest 30 minutes at room temperature (or refrigerate overnight and bring to room temperature for 30 minutes before baking).
  4. Meanwhile, in a medium bowl, add the rolled oats, pecans, turbinado sugar, flour, and 1 teaspoon cinnamon. Cut the butter into the other ingredients using a pastry cutter or fork until evenly combined and a crumbly streusel topping forms. Refrigerate until baking.
  5. Just before baking, sprinkle the streusel topping over the French toast. Bake 40 to 45 minutes until browned and set. Rest 10 minutes before serving.
  6. While the casserole bakes, make the Blueberry Syrup. Scoop out pieces and top with a drizzle of the berry syrup.


*The Blueberry Syrup really adds the blueberry flavor to this casserole. If desired, you can make 1/2 recipe of the syrup, which makes 3/4 cup.
