Pro Tips
Use slightly stale bread for the best results. It absorbs the custard better and helps prevent the casserole from becoming too soft.
Cut the bread into evenly sized cubes so they soak evenly. This helps create a consistent texture throughout the dish.
Whisk the custard thoroughly to ensure all ingredients are well combined. This helps distribute the flavors evenly.
Press the bread gently into the custard after pouring it over. This ensures all pieces are coated and absorb the mixture.
Cover and refrigerate overnight for the best texture and flavor. This allows the bread to fully soak.
Add the optional topping just before baking to create a slightly crisp, caramelized finish.
Tools You’ll Need
- Large mixing bowl
- Whisk
- 9×13-inch baking dish
- Measuring cups and spoons
- Knife and cutting board
- Spatula
- Plastic wrap or foil
Substitutions and Variations
If you don’t have brioche or challah, you can use French bread or another sturdy loaf. Slightly dried bread works best for soaking up the custard.
For a lighter version, you can reduce the cream and use more milk instead. This will slightly reduce the richness but still taste great.
You can add fruits like berries, apples, or bananas for extra flavor and texture. This adds natural sweetness and variety.
For a dairy-free option, use plant-based milk and a dairy-free cream alternative. The dish will still be delicious.
If you want to make it more indulgent, consider adding a streusel topping or a drizzle of maple syrup after baking. This adds a special touch.
Make Ahead Tips
Overnight prep French toast casserole is designed to make mornings easier, and a few thoughtful steps can help you get the best results. After assembling the casserole, cover it tightly with plastic wrap or foil and place it in the refrigerator overnight. This ensures the bread fully absorbs the custard and develops a rich, even texture.
If you’re planning for a busy morning, you can also prepare the optional topping ahead of time. Store it separately so it’s ready to sprinkle on just before baking. This keeps the topping fresh and helps it form a slightly crisp layer.
You can even bake the casserole ahead of time and reheat it when needed. While it’s best served fresh, reheating works well if done properly. This flexibility makes it a great option for meal prep or gatherings.
Instructions
Step 1: Prepare the Baking Dish
Lightly grease a 9×13-inch baking dish with butter or cooking spray. This helps prevent sticking and makes serving easier. Set the dish aside.
Step 2: Arrange the Bread
Place the cubed bread evenly into the prepared baking dish. Spread the pieces out so they are evenly distributed. This helps the custard soak in properly.
Step 3: Make the Custard
In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt. Continue whisking until the mixture is smooth and fully combined. This creates a rich custard base.
Step 4: Combine and Soak
Pour the custard evenly over the bread cubes. Gently press the bread down with a spoon or spatula to ensure all pieces are coated. Cover the dish and refrigerate overnight.
Step 5: Preheat the Oven
When ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for about 20 minutes. Preheat your oven to 350°F. This helps ensure even baking.
Step 6: Add the Topping
If using the optional topping, mix the brown sugar, cinnamon, and melted butter in a small bowl. Sprinkle it evenly over the casserole. This creates a slightly crisp and caramelized layer.
Step 7: Bake the Casserole
Place the dish in the preheated oven and bake for 40–45 minutes. The top should be golden brown, and the center should be set but still soft. If it browns too quickly, cover loosely with foil.
Step 8: Cool and Serve
Remove the casserole from the oven and let it cool for a few minutes before serving. This allows it to set and makes it easier to portion. Serve warm for the best flavor.
Serving Suggestions
Overnight prep French toast casserole pairs beautifully with a drizzle of maple syrup. The sweetness enhances the rich custard and warm spices. It’s a simple and classic option.
Fresh fruit such as berries, sliced bananas, or apples adds brightness and balance. The natural sweetness complements the dish without overpowering it. It also adds a fresh element.
For a more indulgent option, top with whipped cream or a dusting of powdered sugar. This creates a dessert-like experience that’s perfect for special occasions. A drizzle of caramel sauce can add even more richness.
You can also serve it with a side of bacon or sausage. The savory contrast balances the sweetness and makes the meal more filling. It’s a great addition for brunch.
Leftovers and Storage
Allow any leftover casserole to cool completely before storing. Cover the dish tightly or transfer portions to an airtight container. Store in the refrigerator for up to three days.
To reheat, place portions in a 300°F oven until warmed through. This helps maintain the texture and prevents the casserole from becoming too soft. You can also reheat individual portions in a skillet.
For longer storage, this casserole can be frozen. Cut it into portions and place them in a freezer-safe container. It can be stored for up to two months.
When ready to eat, thaw overnight in the refrigerator and reheat in the oven. This helps preserve both flavor and texture. Avoid microwaving if possible.
