    This recipe is near and dear to me. Back in the day, I learned how to make baked french toast casserole in my high school foods class and I have been making it for Christmas morning ever since! You don't necessarily need to wait until Christmas to make this recipe! This delicious gluten-free french toast casserole would be great for a weekend brunch or any morning you want an extra special treat.

    What I Love About This Casserole

    • You make it ahead, as in the night before! Get the mess out of the way and wake up to a delicious breakfast ready for the oven!
    • It has the most delicious cinnamon streusel topping, which is obviously the best part!
    • Topped with frozen blueberries before baking, the tart fruit adds just the right touch.
    • It is a great use for leftover bread that you've been storing up in the freezer!

    Ingredients Needed

    Ingredients for the breakfast casserole measured out.  Toasted bread cubes in a white casserole dish.
    • Gluten-free Bread: Use any kind of gluten-free bread you prefer. I used Canyon Bakehouse in the recipe. You need about 1 loaf's worth. Save up all your leftover bread in the freezer and then use it for this casserole!
    • Eggs, milk, sugar, vanilla, and cinnamon: this makes the french toast base.
    • For the streusel topping, you will need a gluten-free flour blend, brown sugar, cinnamon, and butter.
    • Frozen blueberries

    How to Make It

    The egg mixture is whisked together and poured over the bread cubes.

    Step 1: Toast the bread cubes and place in a casserole dish.
    Step 2: Whisk the eggs, milk, sugar, vanilla, and cinnamon together and pour over the bread cubes. Cover and set aside.

    The topping ingredients are cut together with a pastry knife in a bowl.

    Step 3: Combine the ingredients for the streusel topping with a pastry blender.
    Step 4: Refrigerate the casserole and topping separately, overnight or let sit for at least 30 minutes.

    The streusel topping is sprinkled on top of the casserole.  Then the blueberries are also sprinkled on top.

    In the morning: top the casserole with the streusel topping and blueberries, then bake. Serve warm with a drizzle of maple syrup!

    Maple syrup is drizzled on top of a slice of the casserole.

    Ingredients
      

    • 1 loaf Gluten-free Bread,, about 16oz
    • 6 eggs
    • 2 cups milk
    • 3 tablespoon sugar
    • ½ teaspoon vanilla

    • 6 tablespoons brown sugar

    Instructions
     

    • One Day Ahead:
