Ingredients
- 3 loaves of day-old French bread or brioche, sliced into 1-inch thick pieces (about 12 pounds)
- 24 large eggs
- 4 quarts (16 cups) whole milk
- 2 cups granulated sugar
- 1 cup brown sugar, packed
- 1 tablespoon vanilla extract
- 2 teaspoons ground cinnamon
- 1 teaspoon ground nutmeg
- 1/2 teaspoon salt
- 1 cup unsalted butter, melted
- Optional toppings: powdered sugar, maple syrup, fresh berries, whipped cream
Instructions
- Prepare the bread: Slice the bread into 1-inch thick slices. If using slightly stale bread, that helps it absorb the custard better. Arrange the slices in a large greased 9×13-inch baking dish or a large roasting pan, layering as needed to fit all the bread pieces.
- Make the custard: In a large mixing bowl, whisk together the eggs, milk, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until fully combined.
- Assemble the casserole: Pour the custard evenly over the bread slices, ensuring all pieces are soaked. Use a spatula or spoon to gently press down the bread to help it absorb the custard. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 4 hours, preferably overnight, to allow the flavors to meld.
- Preheat the oven: About 30 minutes before baking, remove the casserole from the refrigerator and preheat the oven to 350°F (175°C). Remove the plastic wrap or foil.
- Bake the casserole: Drizzle the melted butter evenly over the top of the casserole. Bake uncovered for 45-50 minutes, or until the edges are golden brown and the center is set. If you prefer a crisper top, you can broil for an additional 2-3 minutes, watching carefully to prevent burning.
- Serve: Let the casserole rest for 5 minutes before serving. Top with powdered sugar, fresh berries, whipped cream, or a drizzle of maple syrup as desired.
Tips
- Substitutions: For a dairy-free version, use almond or coconut milk and dairy-free butter. Whole wheat or gluten-free bread can be used if needed, but keep in mind that the texture may vary slightly.
- Storage: The assembled casserole can be refrigerated for up to 24 hours before baking. After baking, it’s best enjoyed within 2 days for optimal freshness.
- Common mistakes: Avoid over-soaking the bread, which can make the casserole soggy. Also, ensure the custard is evenly poured to prevent dry spots.
- Additional toppings: Consider adding chopped nuts, coconut flakes, or a sprinkle of cinnamon sugar on top before baking for extra flavor and texture.
Serving Suggestions
This French toast casserole pairs beautifully with fresh fruit, such as sliced strawberries or blueberries. Serve it alongside a side of crispy bacon or sausage for a hearty breakfast. For a more decadent touch, top with whipped cream or a dusting of powdered sugar.
Variations
- Nutella or fruit-filled: Spread Nutella or fruit preserves between layers of bread before assembling for a sweet surprise.
- Apple cinnamon: Add sautéed apples and extra cinnamon to the custard for a warm, fall-inspired flavor.
- Savory version: Skip the sugar and vanilla, add cheese, herbs, and cooked bacon for a savory breakfast casserole.
- Vegan adaptation: Use plant-based milk, vegan bread, and a flaxseed or chia seed mixture as an egg substitute.
Storage and Reheating
Leftover baked casserole can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, slice into portions and microwave on high for 1-2 minutes, or until heated through. For a crisper top, reheat in the oven at 350°F (175°C) for about 10 minutes. If reheating from frozen, allow to thaw overnight in the fridge before warming.
Frequently Asked Questions
Can I prepare this casserole the night before?
Yes, assembling the casserole the night before and refrigerating it overnight is ideal. This allows the bread to soak up the custard fully, resulting in a richer flavor and better texture. Just cover tightly and bake in the morning.
Can I make this recipe gluten-free?
Absolutely. Use a gluten-free bread that is sturdy enough to absorb the custard without falling apart. Some gluten-free bread options work better than others, so choose a dense or slightly stale loaf for best results.
Is it possible to reduce the sweetness?
Yes, you can cut back on the sugar in the custard if you prefer a less sweet dish. Reducing the granulated and brown sugar by half still yields a delicious casserole, especially if topped with sweet toppings like syrup or berries.
How do I keep the casserole moist?
The key is to ensure the bread is fully soaked in the custard and to bake it covered initially if needed. Avoid over-baking, as this can dry it out. Adding a bit more custard before baking can also help if it seems dry.
Can I add other ingredients?
Yes, feel free to customize with chopped nuts, chocolate chips, or dried fruit. Just be mindful of added ingredients that might affect baking time or texture.
What if I don’t have a large dish?
If your dish isn’t large enough, you can split the casserole into two smaller pans or bake in batches. Alternatively, use a larger roasting pan or sheet pan to accommodate all the bread and custard.
