French toast casserole is a crowd-pleasing breakfast dish that combines the comforting flavors of classic French toast with the convenience of baking it all together in a casserole. Perfect for large gatherings, brunches, or weekend family breakfasts, this dish allows you to prepare ahead of time and serve warm, fluffy, and flavorful slices that everyone will love.
Ingredients
- 2 large loaves of day-old brioche bread (about 2 pounds total)
- 12 large eggs
- 4 cups whole milk
- 2 cups heavy cream
- 1 ½ cups granulated sugar
- 1 tablespoon vanilla extract
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ½ teaspoon salt
- ½ cup unsalted butter, melted
- Optional toppings: powdered sugar, maple syrup, fresh berries
Instructions
- Preheat your oven to 350°F (175°C). Grease a large 9×13-inch baking dish or a similarly sized casserole dish that can serve 25 people.
- Cut the brioche bread into 1-inch cubes. Arrange the bread cubes evenly in the prepared baking dish, spreading them out to create a uniform layer.
- In a large mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
- Pour the egg mixture evenly over the bread cubes, ensuring all pieces are soaked. Gently press down on the bread to help it absorb the custard. Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight for best results.
- When ready to bake, remove the casserole from the fridge and let it sit at room temperature for 15-20 minutes. Drizzle the melted butter evenly over the top.
- 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 rest for 5 minutes before serving. Serve warm with your favorite toppings such as powdered sugar, maple syrup, or fresh berries.
Tips
- Substitutions: Use challah or Texas toast if brioche isn’t available. For a dairy-free version, substitute coconut milk and dairy-free butter.
- Storage: Keep leftovers covered in the refrigerator for up to 3 days. Reheat in the microwave or oven until warm.
- Prevent sogginess: Do not soak the bread for too long if you prefer a firmer texture. Also, baking uncovered helps the casserole develop a crispy top.
- Consistency: For a richer custard, add a splash of bourbon or bourbon extract for an adult twist.
Serving Suggestions
Serve the casserole hot from the oven topped with a dusting of powdered sugar, a drizzle of maple syrup, and fresh berries or sliced bananas for a colorful, flavorful presentation. Pair it with crispy bacon or sausage links for a hearty breakfast spread. For an elegant brunch, add a dollop of whipped cream or a side of Greek yogurt.
Variations
Experiment with different flavor profiles by adding ingredients like chopped nuts, raisins, or chocolate chips into the bread layers. You can also swirl in fruit preserves or cream cheese before baking for added richness. For a savory twist, omit the sugar and vanilla, and add cooked breakfast sausage, cheese, and herbs to make a savory baked French toast casserole.
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 bake at 350°F (175°C) for 15-20 minutes or until warmed through. Alternatively, reheat individual portions in the microwave on high for 1-2 minutes, checking for even heating. For best texture, avoid reheating multiple times, as this can cause the bread to become soggy or dry out.
Frequently Asked Questions
Can I prepare this casserole the night before?
Yes, assembling the casserole the night before and refrigerating it overnight is highly recommended. It allows the bread to soak up the custard thoroughly, resulting in a more flavorful and cohesive dish. Just be sure to add the melted butter before baking in the morning.
How do I scale this recipe for fewer or more people?
This recipe is designed for approximately 25 servings. To adjust for fewer guests, halve the ingredients and use a smaller baking dish. For larger crowds, you may need to double the ingredients and use a larger or multiple dishes. Always ensure the bread layer is evenly distributed for consistent cooking.
Can I make this gluten-free?
Yes, substitute the bread with gluten-free bread slices or cubes. Be sure to choose a sturdy gluten-free bread that can absorb the custard without falling apart. The custard mixture remains the same, but baking times may vary slightly based on the bread used.
What toppings go best with this casserole?
Classic toppings include powdered sugar, maple syrup, and fresh berries. You can also add whipped cream, sliced bananas, toasted nuts, or a drizzle of caramel sauce for extra indulgence. For a savory variation, top with cooked bacon and a sprinkle of cheese.
Is this dish suitable for freezing?
Yes, you can freeze cooked and cooled casserole slices in airtight containers for up to 2 months. To reheat, thaw overnight in the refrigerator and bake at 350°F (175°C) for 20-25 minutes until heated through. Freezing is best done before baking if you want to prepare it in advance for later use.
What is the best bread to use for this recipe?
Day-old brioche is ideal because of its rich, buttery texture and ability to soak up custard without falling apart. However, challah, Texas toast, or French bread also work well. Avoid soft, fresh bread that hasn’t dried out, as it may become too soggy or not absorb enough custard.
