Step‑by‑Step Instructions for Overnight Breakfast Casserole
Step 1: Prep the Bread
Begin by preparing your bread for the Healthy Overnight Breakfast Casserole. If it’s not slightly stale, slice it and bake at 300°F for 15 minutes until dried out, allowing it to absorb the custard nicely. Ensure your thick bread—like brioche or sourdough—is cut into 1-inch pieces for even layering.
Step 2: Grease the Baking Pan
Grease a 9×13 inch baking pan with cooking spray or a light coating of olive oil. This simple step prevents any sticking during baking and ensures your casserole comes out beautifully. Once greased, evenly distribute the prepared bread pieces in the pan, creating a sturdy base for your casserole.
Step 3: Mix the Wet Ingredients
In a large mixing bowl or measuring cup, whisk together the applesauce, milk, egg whites, maple syrup, and vanilla extract. This liquid mixture will bind the casserole and create a delightful custard texture. Blend until smooth and everything is well combined, ensuring there are no clumps.
Step 4: Assemble the Casserole
Pour the creamy wet mixture evenly over the layered bread in your baking pan. Gently ensure every piece is soaked for maximum flavor. Next, scatter the berries on top, making sure they’re evenly distributed to burst with sweetness as they cook. Cover the pan tightly with plastic wrap and refrigerate it overnight.
Step 5: Bake the Casserole
The following morning, preheat your oven to 350°F. Once the oven is ready, uncover the baking pan and slide it into the middle rack. Bake for about 1 hour or until the top is lightly golden brown and the interior is set, giving it that perfect custardy texture that defines this Overnight Breakfast Casserole.
Step 6: Serve and Enjoy
Once baked, allow the casserole to cool for about 10 minutes. Slice into portions and serve it warm, or refrigerate it to enjoy later. You can top it with additional fresh sliced fruits, maple syrup, or a drizzle of cream cheese glaze for an extra touch of delight—whichever way you choose, relish in the comforting flavors of your homemade dish!
