Ingredients

  • 1 loaf whole wheat French bread cut into 1-inch cubes
  • 2 cups liquid egg whites or 8 whole eggs
  • 2 cups unsweetened almond milk
  • 1/4 cup pure maple syrup
  • 1 Tbsp vanilla
  • 2 tsp cinnamon
  • 1/4 tsp nutmeg
  • 1 pinch salt
  • 1 cup fresh or frozen blueberries
  • Optional toppings powdered sugar, maple syrup, extra blueberries

Instructions

  • Step 1: Prepare the Bread
    Begin by cutting your whole wheat French bread into 1-inch cubes. This will allow the bread to soak up all the delicious custard mixture. Place the cubes in your baking dish, spreading them out evenly.
  • Step 2: Make the Custard Mixture
    In a large mixing bowl, whisk together the liquid egg whites (or whole eggs), unsweetened almond milk, pure maple syrup, vanilla, cinnamon, nutmeg, and a pinch of salt. Make sure everything is well combined and smooth.
  • Step 3: Combine and Soak
    Pour the custard mixture over the bread cubes, ensuring all pieces are coated. Gently fold in the blueberries, distributing them evenly throughout the bread mixture. Cover the baking dish with plastic wrap and refrigerate overnight.
  • Step 4: Bake the Casserole
    The next morning, preheat your oven to 350°F (175°C). Remove the plastic wrap from the baking dish and bake the casserole for 45-50 minutes, or until the top is golden brown and the center is set.
  • Step 5: Serve and Enjoy
    Once baked, let the casserole cool for a few minutes. Serve warm, topped with powdered sugar, a drizzle of maple syrup, and additional blueberries if desired. Enjoy your delicious Overnight Blueberry French Toast Casserole!
