Ingredients
- 2 loaves of French bread or brioche, sliced into 1-inch thick pieces (about 3 pounds)
- 12 cups whole milk or heavy cream (can mix for richer flavor)
- 24 large eggs
- 2 cups granulated sugar
- 1 cup brown sugar, packed
- 4 teaspoons vanilla extract
- 2 teaspoons ground cinnamon
- 1/2 teaspoon ground nutmeg (optional)
- 1/2 teaspoon salt
- 1 cup unsalted butter, melted
- Powdered sugar, for dusting (optional)
- Maple syrup, for serving
Instructions
- Preheat your oven to 350°F (175°C). Grease a large baking dish or multiple smaller dishes that total approximately 9×13 inches or larger, enough to hold all the bread slices comfortably.
- Arrange the sliced bread in the prepared baking dish(s), overlapping slightly if needed, to create a single layer. For a richer flavor, you can layer the slices to fill the dish completely.
- In a large mixing bowl, whisk together the eggs, milk or cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg (if using), and salt until well combined.
- Pour the egg mixture evenly over the bread slices, making sure to cover all the pieces. Use a spatula or spoon to gently press the bread down so it absorbs the custard mixture.
- Cover the dish tightly with plastic wrap or foil and refrigerate for at least 4 hours, ideally overnight. This allows the bread to soak up the custard fully, resulting in a moist, flavorful casserole.
- When ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for about 20 minutes. Meanwhile, melt the butter and drizzle it evenly over the top of the casserole.
- Bake uncovered in the preheated oven for 45-50 minutes, or until the top is golden brown and a knife inserted into the center comes out clean.
- Remove from oven and let it rest for 5 minutes. Dust with powdered sugar if desired, and serve warm with maple syrup.
Tips
- Substitutions: Use challah or Texas toast for a different flavor and texture. For a dairy-free version, substitute coconut milk or almond milk, though it may alter the richness.
- Storage: Cover and refrigerate leftovers for up to 3 days. Reheat in the oven at 350°F for 15-20 minutes or until warmed through. For longer storage, freeze individual portions and reheat in the microwave.
- Common mistakes: Avoid over-soaking the bread, which can make the casserole soggy. Also, ensure the casserole is baked until the top is golden and the custard is set for the best texture.
- For a crunchier topping, sprinkle chopped nuts or a streusel topping over the casserole before baking.
Serving Suggestions
Serve the French toast casserole warm, topped with a dusting of powdered sugar and a drizzle of pure maple syrup. Complement it with fresh fruit such as berries, sliced bananas, or apple slices for added freshness. A dollop of whipped cream or a side of crispy bacon can also elevate the breakfast experience for your guests.
Variations
For a decadent twist, swirl cream cheese or fruit preserves between layers of bread before baking. You can also add chocolate chips or dried fruits like raisins or cranberries for extra flavor. To make a savory version, omit the sugar and vanilla, and add cooked sausage, cheese, and herbs before baking.
Storage and Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for 1-2 minutes or reheat the entire casserole in a 350°F oven for 15-20 minutes until warmed through. For best results, cover with foil during reheating to prevent drying out.
Frequently Asked Questions
Can I prepare this casserole the night before?
Yes, assembling the casserole the night before and refrigerating it overnight allows the bread to soak up the custard fully. Just take it out of the fridge about 20 minutes before baking to bring it to room temperature.
What type of bread is best for this recipe?
Thick-cut, slightly stale bread like French bread, brioche, challah, or Texas toast works best. Stale bread absorbs the custard better and results in a more flavorful, less soggy casserole.
How do I know when the casserole is fully baked?
Look for a golden-brown top and a custard that is set in the center. Insert a knife or toothpick into the middle—if it comes out clean, the casserole is done. Baking typically takes 45-50 minutes at 350°F.
Can I make this gluten-free?
Yes, substitute gluten-free bread slices for the regular bread. Be sure the bread is sturdy enough to hold the custard and avoid overly soft or crumbly varieties for best results.
Is it suitable for vegan guests?
To make a vegan version, use plant-based milk (like almond or soy), replace eggs with a vegan egg substitute or silken tofu blended smooth, and use vegan butter or coconut oil. Adjust the recipe accordingly for flavor and texture.
Can I add fruit or toppings before baking?
Absolutely! Fresh or dried fruits, nuts, or chocolate chips can be layered or sprinkled on top before baking to add extra flavor and texture.
Enjoy this versatile, crowd-pleasing French toast casserole that’s perfect for large gatherings, holidays, or weekend brunches. Its make-ahead nature and delicious taste make it a go-to recipe for feeding a big group effortlessly.
