1 1/3 cup applesauce (or mashed banana)
2/3 cup milk (of choice)
2/3 cup egg whites (or additional milk of choice)
1/4 cup pure maple syrup (or agave or honey)
1 tsp pure vanilla extract (optional)

Gluten-Free Option: Use gluten-free bread or a hearty grain-free bread for a gluten-free version of this casserole.
Add Nuts or Seeds: Sprinkle in some chopped nuts or seeds (such as almonds or chia seeds) for added crunch and nutrition.
Dairy-Free Version: Use a plant-based milk, such as almond or oat milk, and ensure the bread is dairy-free if needed.

How to Make the Recipe

Step 1: Prepare the Bread

Cut the thick bread into cubes and layer it in the bottom of a baking dish. Ensure the bread covers the bottom evenly.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the applesauce (or mashed banana), milk, egg whites (or additional milk), maple syrup, and vanilla extract (if using). Stir well to combine.

Step 3: Add the Berries

Gently fold in the berries into the wet mixture. You can choose to reserve a handful of berries for topping later if you’d like.

Step 4: Combine and Soak

Pour the wet mixture over the bread cubes in the baking dish, making sure the bread is well-coated. Gently press the bread down to help it absorb the liquid. Cover the dish with plastic wrap or foil and refrigerate it overnight (or for at least 6 hours).

Step 5: Bake the Casserole

In the morning, preheat the oven to 350°F (175°C). Remove the casserole from the fridge and bake for 40-45 minutes, or until the casserole is golden brown and the top is slightly crispy. If you reserved berries for topping, sprinkle them over the casserole in the last 10 minutes of baking.

Step 6: Serve

Allow the casserole to cool slightly before serving. Enjoy it warm as a delicious, hearty breakfast or brunch option!

Tips for Making the Recipe

Use Stale Bread: If you have leftover bread or bread that’s getting stale, it’s perfect for this casserole! Stale bread absorbs the liquid better, resulting in a creamier casserole.
Customize Sweetness: Adjust the amount of maple syrup or sweetener according to your taste. You can also use a sugar-free option if you prefer.
Top with Whipped Cream or Yogurt: For extra indulgence, top each serving with a dollop of whipped cream or a scoop of yogurt.
Use a Larger Dish: If you need to make more servings, simply double the recipe and use a larger baking dish. Just make sure to adjust the baking time accordingly.

How to Serve

As a Brunch Dish: Serve this casserole as part of a hearty brunch, alongside eggs, bacon, or fresh juice for a complete meal.
With Fresh Toppings: Add a drizzle of maple syrup, a handful of nuts, or a scoop of yogurt to elevate the dish further.
As a Sweet Breakfast: Enjoy this casserole as a sweet breakfast option that’s filling and nutritious. Pair it with a hot cup of coffee or tea for the perfect start to your day.
