Blueberry Overnight French Toast Casserole

 Makes 12 Servings - easily halved, see below for details.


Ingredients:
  • 1 large crusty loaf of bread such as french bread or sourdough bread (stale, not fresh - slice and leave out to dry)
  • 1 cup fresh or frozen blueberries
  • 8 large eggs
  • 2 and 1/4 cups (540ml) Full cream milk
  • 1/2 teaspoon ground cinnamon
  • 3/4 cup packed brown sugar
  • 1 Tablespoon  vanilla essence
Streusel Topping
  • 1/3 cup  packed brown sugar
  • 1/3 cup (42g) plain flour (spoon & leveled)
  • 1/2 teaspoon ground cinnamon
  • 86g unsalted butter, cold and cubed
  • Optional: extra blueberries, fresh fruit, maple syrup, and/or icing sugar for topping

Directions:
  1. Grease a 23x33cm pan to prevent sticking
  2. Slice then cut the bread into cubes, about 2.5cm in size. You will need about 12 cups of cubes. Spread cubes into the prepared baking dish and top with the blueberries. Set aside.
  3. Whisk the eggs, milk, cinnamon, brown sugar, and vanilla together until no brown sugar lumps remain. Pour over the bread. Cover the pan tightly with Gladwrap and stick in the refrigerator for 3 hours - overnight. Preferably overnight.

  4. Preheat oven to 180C. Remove pan from the refrigerator.

  5. Prepare the streusel topping: Whisk the brown sugar, flour, and cinnamon together in a medium bowl. Cut in the cubed butter with a food processor or two forks - Grating works well but work fast! Sprinkle the topping over the soaked bread. (Streusel Topping can be made ahead of time and stored in the fridge.)
  6. Bake for 45-55 minutes or until golden brown on top. If you prefer the casserole less 'custardy' cover with foil after 45 minutes and cook for up to 20 minutes longer depending upon your preference.
  7.  Dust with Icing sugar and serve immediately with extra blueberries, fresh fruit, maple syrup and bacon if you wish!
  8. Cover leftovers tightly and store in the refrigerator for 2-3 days.
