Step‑by‑Step Instructions for Overnight French Toast Casserole
Step 1: Prepare the Bread
Spread the cubed bread evenly on a large cookie sheet and allow it to dry out for about an hour. This step is crucial for achieving a perfectly textured Overnight French Toast Casserole, ensuring the bread can absorb the custard without becoming soggy.
Step 2: Make the Custard
In a large mixing bowl, whisk together the eggs, milk, salt, granulated sugar, vanilla extract, cinnamon, and nutmeg until well combined. Aim for a smooth and creamy consistency. This will form the rich custard that envelops the bread, enhancing the flavor of your casserole.
Step 3: Assemble Casserole
Grease a 9" x 13" baking dish with butter or cooking spray. Layer half of the dried bread cubes evenly on the bottom. If you are using bacon or breakfast sausage, sprinkle half over the bread before adding the remaining bread to create delicious layers throughout your Overnight French Toast Casserole.
Step 4: Pour Custard
Carefully pour the prepared custard mixture over the layered bread, making sure every piece is fully submerged. This ensures that each bite of your Overnight French Toast Casserole is infused with its flavor. Gently press the bread down using a spatula to ensure even soaking.
Step 5: Refrigerate
Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours or, ideally, overnight. This resting period allows the bread to soak up the custard thoroughly, enhancing the flavors and ensuring a delightful texture when baked.
Step 6: Bake
Preheat your oven to 350°F (175°C). Remove the cover from the casserole and bake for 60–70 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The top should be lightly crisp while the inside remains custardy—just perfect for your Overnight French Toast Casserole.
Step 7: Serve
Once baked, let the casserole cool for a few minutes. If desired, dust the top with cinnamon sugar for an extra sweet crunch, and serve warm with a drizzle of maple syrup, whipped cream, or fresh fruit to elevate your delicious Overnight French Toast Casserole!
