Step‑by‑Step Instructions for Overnight Breakfast Casserole

Step 1: Prepare the Bread
Start by drying out your bread for the Overnight Breakfast Casserole. If it’s not slightly stale, preheat your oven to 300°F and arrange the thick bread slices on a baking sheet. Bake for about 15 minutes, or until the bread is dry to the touch, ensuring a perfect texture to soak up the delicious custard later on.

Step 2: Grease the Baking Pan
While the bread is drying, generously grease a 9×13 inch baking pan with butter or cooking spray. Once the bread is ready, cut it into 1-inch cubes and layer them evenly in the pan, allowing them to create a sturdy base that will hold all the wonderful flavors of the Overnight Breakfast Casserole.

Step 3: Mix the Custard Ingredients
In a large measuring cup, whisk together the applesauce, your choice of milk, and egg whites if you’re using them. Add in pure maple syrup and vanilla extract for added flavor. This mixture is essential for creating a creamy, luscious filling that will soak into the bread, so mix well until everything is thoroughly combined.

Step 4: Pour the Custard Over the Bread
Carefully pour the custard mixture evenly over the layered bread cubes, ensuring that all pieces are well-coated. Gently press down on the bread with a spatula to help it absorb the liquid. Once soaked, scatter your choice of berries on top, adding a burst of sweetness that’s perfect for your Overnight Breakfast Casserole.

Step 5: Refrigerate or Bake Immediately
Cover the baking pan with plastic wrap or aluminum foil. At this stage, you can either refrigerate the casserole overnight to allow the flavors to meld or choose to bake it immediately if you’re craving it right away. If you refrigerate, aim to let it sit for at least 8 hours for optimal results.

Step 6: Preheat and Bake
The next morning, preheat your oven to 350°F. Once heated, remove the cover from your Overnight Breakfast Casserole and bake for about 1 hour, or until the top is golden brown and slightly crispy. You’ll know it’s done when the casserole has puffed slightly and a toothpick inserted in the center comes out clean.

Step 7: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes. This resting period allows it to set up a bit further. Serve warm, with a drizzle of maple syrup or a dollop of whipped cream, making your Overnight Breakfast Casserole a delightful start to any morning!

Make Ahead Options

These Overnight Breakfast Casserole recipes are perfect for busy mornings and meal prep! You can prepare the casserole up to 24 hours in advance by following the initial steps and then covering it to refrigerate overnight, which allows the flavors to meld beautifully. If you’re short on time, you can also combine the bread and custard mixture, cover it, and refrigerate for up to 3 days before baking – just remember to let it sit at room temperature for about 20 minutes prior to baking to ensure even cooking. For best quality, don’t add the berries until just before baking to prevent excess moisture. Simply preheat your oven to 350°F the next morning, bake for about 1 hour, and enjoy this scrumptious Overnight Breakfast Casserole with your loved ones!
