Perfect for feeding 30 people, it combines the comforting flavors of classic French toast with the convenience of a baked casserole.
Ingredients
- 2 loaves of day-old French bread or brioche, cut into 1-inch cubes (about 24 cups)
- 12 large eggs
- 4 cups whole milk
- 2 cups heavy cream
- 1 1/2 cups granulated sugar
- 1 tablespoon vanilla extract
- 2 teaspoons ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, melted
- 1 cup brown sugar (for topping)
- 1/2 cup all-purpose flour (for topping)
- 1/2 cup chopped pecans or walnuts (optional, for topping)
- Powdered sugar and maple syrup, for serving
Instructions
- Preheat your oven to 350°F (175°C). Grease a large 9×13-inch baking dish or a similar-sized casserole dish. If preparing for a large crowd, consider using two dishes or a large commercial-sized baking pan.
- Place the bread cubes evenly in the prepared baking dish, spreading them out to create an even layer.
- In a large mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla, cinnamon, nutmeg, and salt until well combined.
- Pour the egg mixture evenly over the bread cubes, pressing down gently to ensure the bread absorbs the custard. Cover the dish with plastic wrap or foil and refrigerate for at least 2 hours, preferably overnight. This allows the bread to soak up the custard fully.
- In a small bowl, combine the brown sugar, flour, and chopped nuts (if using). Add the melted butter and mix until crumbly. This will be your topping.
- Remove the casserole from the refrigerator and sprinkle the topping evenly over the soaked bread.
- Bake uncovered in the preheated oven for 45-50 minutes, or until the top is golden brown and the custard is set. To check for doneness, insert a toothpick into the center; it should come out clean.
- Allow the casserole to cool slightly for 10 minutes before serving. Dust with powdered sugar and serve with warm maple syrup for an extra touch of sweetness.
Tips
- Substitutions: Use gluten-free bread if needed, or swap heavy cream for half-and-half for a lighter version. You can also add berries or sliced bananas into the casserole before baking for added flavor.
- Storage: Keep leftovers covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 1-2 minutes or in the oven at 350°F until warmed through.
- Common mistakes: Ensure the bread is slightly stale or day-old to absorb the custard better; fresh bread may turn mushy. Also, do not skip refrigerating; it helps the bread soak fully.
- Cooking time: If your casserole is larger or thicker, add extra baking time in 5-minute increments. Use a thermometer to confirm the custard reaches 160°F for safety.
Serving Suggestions
Serve this French toast casserole warm, topped with a dusting of powdered sugar and a drizzle of pure maple syrup. Complement with fresh fruit like strawberries, blueberries, or sliced bananas. A side of crispy bacon or sausage links pairs beautifully for a hearty breakfast.
Variations
For a decadent twist, swirl in cream cheese or mascarpone into the custard before baking. You can also add chocolate chips or dried fruit into the bread layers for extra flavor. To make it more festive, sprinkle festive spices like ginger or cloves into the custard mixture. For a healthier option, use whole wheat bread and reduce the sugar slightly, or top with Greek yogurt instead of syrup.
Storage and Reheating
Leftover French toast casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F oven for 15-20 minutes until heated through. Alternatively, individual portions can be microwaved on high for 1-2 minutes, checking for even warming. For longer storage, you can freeze individual servings wrapped tightly in plastic wrap and foil for up to 1 month. Reheat directly from frozen in the oven or microwave.
Frequently Asked Questions
Can I prepare this casserole the night before?
Absolutely. Assemble the casserole, cover tightly, and refrigerate overnight. Baking in the morning will result in a fully soaked, flavorful dish that’s ready to serve.
Can I make this gluten-free?
Yes, simply substitute the bread with gluten-free bread slices. Ensure the bread is slightly stale to absorb the custard well. The rest of the ingredients are naturally gluten-free.
How do I know when it’s done baking?
Look for a golden-brown top and a custard that is set and no longer liquid in the center. You can insert a toothpick into the middle; if it comes out clean, it’s ready. The internal temperature should reach 160°F for safety.
Can I add fruit or nuts?
Yes, adding fresh or dried fruit like berries, sliced apples, or bananas enhances flavor. Nuts such as pecans or walnuts add crunch. Sprinkle them on top before baking or mix into the bread layers.
Is it suitable for dietary restrictions?
This recipe can be adapted for certain dietary needs. Use plant-based milk and egg substitutes for a vegan version, or gluten-free bread for gluten intolerance. Adjust sugar and toppings accordingly.
Can I freeze leftovers?
Yes, freeze individual portions in airtight containers or freezer bags for up to a month. Reheat in the oven or microwave for a quick breakfast or brunch.
