Step‑by‑Step Instructions for Best-Ever Overnight French Toast Casserole

Step 1: Prepare Bread
Start by preheating your oven to 350°F. Cut the sourdough bread into 1-inch cubes and spread them evenly in a greased 9×13-inch baking dish. Make sure each piece is well-placed, allowing for optimal soaking later. This sturdy structure helps prevent a soggy French toast casserole, setting the stage for a delightful breakfast treat.

Step 2: Mix Custard
In a medium bowl, whisk together the eggs, milk, heavy cream, vanilla extract, and sugar until the mixture is smooth and well blended. This rich custard will soak into the bread, creating that wonderful soft texture. Pour the custard evenly over the bread cubes, ensuring each piece is soaked, then gently press down the bread to immerse it fully in the liquid.

Step 3: Refrigerate
Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours, or ideally overnight. This step allows flavors to meld and ensures that the bread absorbs the custard thoroughly, resulting in a moist and flavorful French toast casserole. Once it’s ready to bake, you’ll be amazed at how beautifully plumped the bread will look!

Step 4: Make Topping
While your casserole is chilling, prepare the topping by mixing the all-purpose flour, light brown sugar, ground cinnamon, and salt in a bowl. Cut in the cold, unsalted butter using a pastry cutter or your fingertips until the mixture resembles coarse crumbs. Refrigerate this topping until you’re ready to bake, keeping it nice and cold for a delightful crunch.

Step 5: Preheat Oven
Before baking the casserole, make sure your oven is preheated to 350°F. This temperature ensures that the French toast casserole cooks evenly, allowing the custard to set beautifully and the topping to become golden and crispy. The tantalizing aroma filling your kitchen will set everyone’s expectations high for what’s to come!

Step 6: Bake
Remove the plastic wrap and sprinkle the crumbly topping generously over the soaked bread mixture. Place the baking dish in the preheated oven and bake for 45-60 minutes, or until the top is golden brown and the custard is fully set. You’re looking for a golden crust with a soft yet firm center, a perfect combination for your French toast casserole to shine!
