Ingredients

Main Ingredients

  • 1 loaf French bread (10 cups, cut into 1-inch cubes)
  • 1 ½ cups fresh or frozen blueberries
  • 8 large eggs
  • 2 ¼ cups whole milk
  • 1 teaspoon cinnamon
  • ½ teaspoon ground nutmeg
  • ¾ cup packed brown sugar
  • 1 tablespoon vanilla extract

Topping

  • 1/3 cup brown sugar
  • 1/3 cup all-purpose flour
  • 1 teaspoon cinnamon
  • 6 tablespoons cold butter, cut into small pieces
  • ½ cup chopped pecans

Instructions

  1. Prepare the Baking Dish: Grease a 9×13-inch baking dish thoroughly with non-stick cooking spray to ensure easy release after baking.
  2. Cut and Layer Bread: Slice the French bread into 1-inch cubes and evenly spread them in the greased baking dish.
  3. Add Blueberries: Scatter fresh or frozen blueberries evenly over the bread cubes for bursts of fruit flavor.
  4. Make Custard Mixture: In a medium bowl, whisk together the eggs, whole milk, cinnamon, ground nutmeg, brown sugar, and vanilla extract until fully combined.
  5. Soak Bread: Pour the egg mixture over the bread and blueberries, gently tossing or pressing down to ensure all pieces are coated.
  6. Chill: Cover the dish with plastic wrap and refrigerate for at least 3 hours or overnight to allow the bread to soak up the custard fully.
  7. Preheat Oven: Remove the casserole from the refrigerator and preheat your oven to 350°F (175°C).
  8. Prepare Topping: In a small bowl, combine brown sugar, all-purpose flour, and cinnamon. Cut in the cold butter pieces using a pastry cutter or fork until the mixture becomes crumbly.
  9. Add Pecans: Stir chopped pecans into the crumbly topping mix evenly.
  10. Top Casserole: Sprinkle the pecan streusel mixture uniformly over the soaked bread base.
  11. Bake: Place the casserole in the preheated oven and bake for 50 to 55 minutes, or until the top is golden brown and the custard is set.
  12. Finish and Serve: Once baked, optionally sprinkle powdered sugar on top before serving to add a touch of sweetness and visual appeal.

Notes

  • For best results, soak the casserole overnight to enhance flavor and texture.
  • Use day-old French bread for a sturdier texture that absorbs the custard without becoming mushy.
  • Fresh or frozen blueberries both work well; if using frozen, do not thaw before adding.
  • If pecans are unavailable or undesired, walnuts or almonds make great substitutes.
  • Ensure butter is cold when making the topping for optimal crumbly texture.
  • Leftovers can be refrigerated and reheated in the oven or microwave.
