How to Make Traditional French Toast Casserole

Making this French Toast Casserole is simple! Below are the ingredients you will need to gather and easy-to-follow steps to create this delicious dish.

Ingredients:

1 loaf brioche (challah, or French bread, cut into 1-inch cubes)
6 large eggs
2 cups whole milk
1/2 cup granulated sugar
1 tablespoon vanilla extract
1 teaspoon ground cinnamon
1/4 teaspoon salt
1/2 cup unsalted butter (melted)

Directions:

Preheat Oven: Start by preheating your oven to 350°F. This step is important to ensure even cooking and a perfect golden brown top.
Prepare Baking Dish: Take a 9×13-inch baking dish and grease it using butter or nonstick spray. This will prevent the casserole from sticking and make for easy serving later.
Add Bread Cubes: Spread the bread cubes evenly in the prepared baking dish. Make sure the pieces are closely packed but not too tightly to allow for even soaking.
Combine Wet Ingredients: In a large mixing bowl, whisk together the eggs, whole milk, granulated sugar, vanilla extract, ground cinnamon, and salt. Mix it well until everything is combined and smooth. This mixture forms the custard that gives the casserole its rich flavor.
Pour Over Bread: Pour the egg mixture evenly over the bread cubes. Use a spatula or your hands to press down lightly on the bread cubes. This will help them absorb the custard mixture thoroughly.
Drizzle Butter: Next, take the melted butter and drizzle it over the top of the bread and custard mixture. This will create a nice, crispy, and flavorful topping when baked.
Let it Soak: Allow the casserole to sit for about 10 minutes. This waiting time lets the bread soak up the custard mixture, ensuring every bite is flavorful and moist.
Bake: Place the dish in the preheated oven and bake uncovered for about 40 minutes. Keep an eye on it; the casserole is done when the top is golden brown and the center is set.
Cool and Serve: Once baked, remove from the oven and let it cool slightly before serving. This allows it to firm up a bit, making it easier to cut into squares. Serve warm with maple syrup, a dusting of powdered sugar, or fresh berries for a delicious finishing touch.

How to Serve Traditional French Toast Casserole

Serving this French toast casserole is incredibly easy. You can cut it into squares or large rectangles and place them onto individual plates. Drizzle warm maple syrup over each piece for a classic touch. You might also sprinkle some powdered sugar on top for a sweet finishing touch.

If you want to add color and freshness to the dish, serve it with fresh berries like strawberries, blueberries, or raspberries on the side. These add a burst of flavor and a lovely presentation to your breakfast table. For a fun twist, consider adding whipped cream or even a scoop of ice cream on the side for a special treat!

How to Store Traditional French Toast Casserole

If you have leftovers, storing them is quite simple. Once the casserole has cooled down, you can cover the baking dish with plastic wrap or transfer the individual pieces to an airtight container.

Keep it in the refrigerator for up to 3 days. When you’re ready to enjoy it again, simply reheat individual portions in the microwave or warm the entire casserole in the oven at 350°F until heated through. For best results, cover the dish with foil to avoid over-browning the top.

Tips to Make Traditional French Toast Casserole

Use Stale Bread: For the best texture, use bread that is a day or two old. Stale bread absorbs the custard better than fresh bread, resulting in a richer dish.
Mix-Ins: Feel free to customize the recipe by adding chocolate chips, nuts, or dried fruit into the bread mixture before pouring the custard. This adds flavor and texture to the casserole.
Flavors: Consider adding a pinch of nutmeg or a splash of orange zest to enhance the flavors of the custard mixture.
Make Ahead: To save time, prepare the casserole the night before. You can cover it and leave it in the fridge overnight, then bake it in the morning.

Variation

While the traditional French Toast Casserole recipe is delightful on its own, you can try a few variations to switch things up.

Berry French Toast Casserole: Add a layer of fresh or frozen mixed berries between the bread layers for a fruity twist.
Chocolate Chip Casserole: Include chocolate chips in the mixture for a dessert-like breakfast.
Savory Version: For a savory option, use cheese and add cooked bacon or sausage, substituting some seasoning to reflect a more savory profile.
