Step‑by‑Step Instructions for French Toast Casserole
Step 1: Prep the Egg Mixture
In a large mixing bowl, whisk together 8 large eggs, 2 cups of milk, ½ cup heavy cream, 1 cup granulated sugar, 1½ teaspoons vanilla extract, and ½ teaspoon ground cinnamon. Ensure the mixture becomes smooth and homogeneous, with a creamy texture reflecting the custard’s richness. This is a crucial step for your French Toast Casserole, allowing all flavors to blend beautifully.
Step 2: Soak the Bread
Cut your choice of bread (sourdough, brioche, or French) into 1-inch squares, and add them to the egg mixture. Gently fold until all pieces are soaked, ensuring thorough coverage for a custard-like texture. Once fully combined, cover the bowl with plastic wrap and refrigerate for at least 3 hours or ideally overnight. This soaking process deepens the flavors and enhances the casserole’s fluffiness.
Step 3: Make the Topping
Preheat your oven to 350°F (175°C) to prepare for baking. In a small bowl, combine ½ cup all-purpose flour, ½ cup packed brown sugar, 1½ teaspoons ground cinnamon, and a pinch of salt for the topping. Cut in 1 stick of diced butter using a pastry blender or your fingers until the mixture resembles coarse sand. This crunchy topping will provide a delightful contrast to the soft custard below.
Step 4: Assemble and Bake
Grease a 9×13-inch casserole dish with butter or cooking spray to prevent sticking. Transfer the soaked bread mixture evenly into the dish, spreading it out to ensure even cooking. Generously sprinkle the prepared topping over the bread mixture. Bake in the preheated oven for 50 minutes or until the topping is golden brown and the egg mixture is fully set in the center, achieving that perfect balance of textures.
Step 5: Glaze and Serve
Once baked, allow the French Toast Casserole to cool for a few minutes before slicing. In the meantime, create a glaze by mixing ½ cup powdered sugar with 2 tablespoons of milk until smooth. Drizzle this sweet glaze over the warm casserole, enhancing its charm. Serve each slice warm, and watch as those delightful aromas fill the room!

Make Ahead Options
This Easy Overnight French Toast Casserole is a fantastic choice for busy mornings, as it can be prepared up to 24 hours in advance. Begin by soaking the bread cubes in the egg mixture and covering it tightly with plastic wrap before placing it in the refrigerator overnight. This allows the flavors to meld beautifully while preventing the bread from becoming soggy. For the best results, assemble the casserole right before baking; simply sprinkle the topping over the soaked bread and pop it in the oven when ready to serve. This way, you’ll enjoy a warm, delicious breakfast without any morning hustle, making it perfect for weekend gatherings or holiday brunches!
