Step‑by‑Step Instructions for French Toast Casserole
Step 1: Prep the Baking Dish
Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish generously with unsalted butter or nonstick spray, ensuring every corner is well-coated. This will prevent the French Toast Casserole from sticking and help it achieve that perfect golden exterior.
Step 2: Bread Base
Take your day-old brioche, challah, or French bread and cut it into 1-inch cubes. Evenly distribute the bread cubes in the prepared baking dish, creating a cozy and hearty base. Make sure to arrange them in a single layer for optimal absorption of the custard, allowing for even cooking.
Step 3: Custard Mixture
In a large mixing bowl, whisk together 6 eggs, 2 cups of whole milk, ¼ cup of granulated sugar, 1 tablespoon of vanilla extract, a sprinkle of ground cinnamon, and a pinch of nutmeg. Blend until well combined, creating a smooth custard mixture. This is the heart of your French Toast Casserole, adding richness and flavor.
Step 4: Combine & Soak
Pour the custard mixture evenly over the bread cubes in the baking dish. Gently press down on the bread to ensure every piece absorbs the custard, promoting a moist and flavorful result. Let it sit for about 10 minutes if making the Classic version, or cover and refrigerate overnight for the Overnight variation.
Step 5: Butter Drizzle
For the Classic French Toast Casserole, melt ½ cup of unsalted butter and drizzle it evenly over the top before baking. If you’re preparing the Overnight version, mix ½ cup of brown sugar with the melted butter and pour this mixture over the casserole just before it goes into the oven to add extra sweetness and a caramelized edge.
Step 6: Bake
Place the baking dish in the preheated oven and bake uncovered for 30 to 45 minutes. You’ll know it’s ready when the top is golden brown and the center is set, creating a beautiful contrast with a slightly soft and custardy texture beneath. Keep an eye on it after 30 minutes to prevent over-browning.
Step 7: Serve
Once baked, remove the French Toast Casserole from the oven and let it cool slightly for about 10 minutes. This resting time helps firm up the casserole. Serve it warm with a drizzle of maple syrup, a dusting of powdered sugar, or fresh berries for a delightful topping that enhances the cozy flavors.
