How to Make Overnight French Toast Casserole Recipe
Step 1: Prepare the Baking Dish and Arrange the Bread
Begin by generously buttering or spraying your 9-inch by 13-inch baking dish to ensure nothing sticks. Next, slice your French bread or Texas toast into thick, even pieces. Arrange these slices snugly in the dish, layering them to create a sturdy base that will soak up all that delicious custard.
Step 2: Whisk Together the Custard Mixture
In a large bowl, combine the eggs, half and half, milk, granulated sugar, pure vanilla extract, ground cinnamon, nutmeg, and salt. Whisk thoroughly until everything is perfectly blended into a smooth, creamy custard. This mixture is what transforms your bread into a tender, flavorful dream.
Step 3: Pour Custard Over Bread and Refrigerate Overnight
Pour the custard mixture evenly over the arranged bread slices, making sure each piece gets soaked well. Cover the dish tightly with plastic wrap or foil and pop it into the refrigerator. This overnight soak is the magic moment where the bread absorbs all the custardy goodness, setting the stage for a delicious bake.
Step 4: Preheat Oven and Flip Bread Slices
When you’re ready to bake, preheat your oven to 350°F. Carefully flip each bread slice in the dish to ensure even cooking and better topping adhesion later. This simple step helps create a perfectly golden crust and an even texture throughout the casserole.
Step 5: Prepare and Spread the Topping
Mix together the softened butter, packed light brown sugar, light corn syrup if using, ground cinnamon, and nutmeg until you have a spreadable, fragrant topping. Dollop and gently spread this mixture evenly over the flipped bread slices, promising a crunchy, sweet finish that perfectly complements the soft custard.
Step 6: Bake Until Golden and Puffy
Bake your casserole for 35 to 40 minutes, or until it’s puffed up and glowing golden brown on top. The aroma will fill your kitchen with irresistible warmth, signaling that your Overnight French Toast Casserole Recipe is ready to delight.
How to Serve Overnight French Toast Casserole Recipe
Garnishes
To make each serving shine, consider topping your casserole with fresh berries, a dusting of powdered sugar, or a drizzle of maple syrup. These simple garnishes add bursts of color, fresh flavor, and just the right touch of sweetness or tartness that elevates the experience.
Side Dishes
This casserole pairs beautifully with crispy bacon or savory sausages for a well-rounded breakfast, but don’t stop there—fresh fruit salad or a light yogurt parfait can offer bright, fresh contrasts that balance the richness perfectly.
Creative Ways to Present
Serve the casserole in rustic individual ramekins for an inviting, personal touch at your brunch table. Alternatively, present it as a big family-style dish to encourage sharing and conversation. Either way, the comforting look and smell will draw everyone in eagerly.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (though that might be a challenge), store them tightly covered in the fridge for up to 3 days. Reheating will bring back that delicious warmth without drying out the dish.
Freezing
You can freeze baked casserole portions wrapped well in foil or plastic wrap for up to 2 months. Thaw overnight in the refrigerator before reheating for best texture and flavor.
Reheating
Reheat leftovers in a 350°F oven for about 10-15 minutes until warmed through and crisp on top. Avoid microwaving to keep the topping delightfully crunchy and the custard creamy.
FAQs
Can I use other types of bread for this casserole?
Absolutely! While French bread or Texas toast works best for texture, you can experiment with challah, brioche, or even sturdy sandwich bread. Just avoid soft or crumbly breads that might fall apart during soaking.
Is it possible to make this recipe dairy-free?
Yes, substitute the half and half and milk with your favorite plant-based milk alternatives like almond or oat milk, and use dairy-free butter for the topping. The result will still be deliciously satisfying.
How long can I soak the bread in custard?
Overnight soak is ideal to achieve maximum flavor and custard absorption, but you can soak it for as little as 4 hours if you’re short on time. The texture will be slightly less rich but still tasty.
What makes the topping so special?
The combination of brown sugar, butter, cinnamon, and nutmeg caramelizes beautifully in the oven, adding a perfect sweet crunch that contrasts the soft, creamy custard underneath. Light corn syrup is optional but adds a glossy shine and extra stickiness.
Can I double the recipe for a larger crowd?
Yes, just double all the ingredients and bake in a larger dish or two separate 9×13 pans. Keep an eye on baking time—it may need a few extra minutes depending on thickness.
Final Thoughts
You really can’t go wrong with this Overnight French Toast Casserole Recipe.

- 1 Tbsp light corn syrup (optional)
- 1 teaspoon ground cinnamon

Instructions
- Prepare the baking dish and bread: Coat a 9×13-inch baking dish thoroughly with butter or cooking spray to prevent sticking. Slice the French bread into even pieces and arrange them neatly in the baking dish.

- Bake the casserole: Place the dish in the preheated oven and bake for 35 to 40 minutes, or until the casserole is puffed up and the topping is golden and bubbly. Remove from oven and let it cool slightly before serving.
Notes
- For best results, use day-old French bread or Texas toast as it soaks up the custard better without becoming too mushy.

- You can enhance flavor by adding a pinch of ground cloves or a splash of bourbon to the custard mixture for a festive twist.
- This casserole can be prepared up to 24 hours in advance, making it perfect for busy mornings or holiday brunches.
- Serve with maple syrup, fresh berries, or whipped cream for added indulgence.
