French Toast Casserole Ingredients
• The secret to this delightful dish lies in the simple yet essential ingredients that create a comforting breakfast experience.
For the Casserole

- Eggs (8 large) – The backbone of the custard; essential for binding and adding richness to your French Toast Casserole.
- Milk (2 cups) – Adds creaminess; substitute with almond or oat milk for a lactose-free option.
- Heavy cream (½ cup) – For that extra richness in the custard; replace with additional milk for a lighter variation.
- Vanilla extract (1½ teaspoons) – Elevates the flavor; using pure extract will achieve the best results.
- Sugar (1 cup) – Sweetens your casserole nicely; brown sugar can provide a deeper flavor if you’re looking for something special.
- Ground cinnamon (½ teaspoon) – Brings warmth and aromatic spice; adjust according to your taste preferences or swap with nutmeg for a different twist.
For the Topping
- All-purpose flour (½ cup) – Used to create a crumbly topping; for a gluten-free option, swap with a gluten-free flour blend.
- Brown sugar (½ cup, packed) – Works with flour to create that satisfying crunch; adds a hint of molasses flavor.
- Ground cinnamon (1½ teaspoons) – Reinforces the cinnamon flavor in the topping; feel free to adjust based on your personal taste.
- Pinch of salt – Enhances the sweetness and balances the flavors.
- Butter (1 stick, cut into small dice) – Provides richness and helps create that delightful crumble on top.

Step‑by‑Step Instructions for French Toast Casserole
Step 1: Prepare the Custard Mixture
In a large mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, and ground cinnamon until well combined. This mixture should be smooth and creamy, taking about 2-3 minutes. Set it aside while you prepare the bread, ensuring every ingredient is evenly incorporated to create a rich custard for the French Toast Casserole.
Step 2: Cube the Bread
Cut your chosen bread into 1-inch squares and place them in a separate large bowl. Gently fold the bread pieces into the prepared custard mixture, making sure that each piece is well-soaked. This process should take about 5 minutes. You want the bread to absorb the custard thoroughly, which will ensure a soft, custardy texture once baked.
Step 3: Refrigerate the Mixture
Once the bread is evenly coated, cover the bowl with plastic wrap and refrigerate the mixture for at least 3 hours, though overnight is preferred. This allows the flavors to meld and the bread to soak up even more custard, enhancing the overall taste and texture of the French Toast Casserole.
Step 4: Preheat the Oven
About 30 minutes before you’re ready to bake, preheat your oven to 350°F (175°C). This will ensure that your oven is hot enough to create that golden, crispy top. While the oven warms up, you can prepare your topping mixture and casserole dish, making the transition to baking seamless.
Step 5: Make the Topping
In a small bowl, combine the all-purpose flour, packed brown sugar, ground cinnamon, and a pinch of salt. Mix these dry ingredients together using a fork or pastry cutter, then cut in the cold, diced butter until the mixture resembles coarse sand. This crumbly topping will add a delightful crunch to your French Toast Casserole.
Step 6: Assemble the Casserole
Grease a 9×13-inch casserole dish with non-stick spray or butter and pour the soaked bread mixture into it, spreading it evenly. Ensure the bread is well-distributed in the dish, then sprinkle the prepared topping mixture generously over the top. This step adds the perfect crunchy layer to your comforting dish.
Step 7: Bake the Casserole
Place the casserole in the preheated oven and bake for about 50 minutes, or until the top is golden brown and a knife inserted in the center comes out clean. Keep an eye on the casserole, and consider covering it with aluminum foil for the first 25 minutes to prevent over-browning while ensuring it cooks evenly.
Step 8: Glaze and Serve
Once fully baked, remove the French Toast Casserole from the oven and let it cool for about 10 minutes. While it cools, whisk together the powdered sugar and milk to create a smooth glaze. Drizzle the glaze over the warm casserole for a sweet finishing touch, and serve hot, enjoying the deliciousness of this homemade breakfast masterpiece!
