Instructions

Preparation Steps:

  • Step 1: Prepare the Bread - Begin by cutting your whole wheat French bread into 1-inch cubes. Place the cubes in a large mixing bowl and set aside.
  • Step 2: Whisk the Custard - In a separate large mixing bowl, whisk together the liquid egg whites (or whole eggs), unsweetened almond milk, pure maple syrup, vanilla extract, cinnamon, nutmeg, and a pinch of salt until well combined.
  • Step 3: Combine Bread and Custard - Pour the custard mixture over the bread cubes and gently fold until all pieces are evenly coated.

  • Step 5: Refrigerate Overnight - Transfer the mixture into a greased 9x13-inch baking dish. Cover with plastic wrap and refrigerate overnight.
  • Step 6: Bake the Casserole - Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake for 45-50 minutes, or until golden brown.
  • Step 7: Serve and Enjoy - Allow to cool slightly before serving. Dust with powdered sugar, drizzle with maple syrup, or add extra blueberries.
