This French Toast Casserole is a delightful dish that combines the rich flavors of challah or brioche bread with a creamy custard, making it the perfect breakfast or brunch option. It’s simple to prepare and can even be made ahead of time, allowing you to enjoy a leisurely morning without the fuss. This dish is rich, indulgent, and can be served with your favorite toppings like fresh fruit, maple syrup, or whipped cream.
Step 1: Prepare the Caramel Sauce
Melt the Butter: In a saucepan over medium heat, melt the unsalted butter.
Add Sugar and Corn Syrup: Stir in the packed brown sugar and light corn syrup. Continue stirring until the mixture is bubbly and smooth.
Pour into Baking Dish: Remove from heat and pour the caramel mixture into the bottom of a greased 9x13 inch baking dish, spreading it evenly.
Step 2: Assemble the Casserole
Layer the Bread: Arrange the sliced challah or brioche bread in a single layer on top of the caramel sauce in the baking dish. You can overlap the slices slightly if needed.
Make the Custard Mixture: In a large mixing bowl, whisk together the eggs, half-and-half cream, vanilla extract, Grand Marnier (if using), and salt until well combined.
Pour Custard Over Bread: Pour the custard mixture evenly over the bread slices, ensuring all the pieces are coated.
Step 3: Chill and Bake
Chill (Optional): If you have time, cover the dish with plastic wrap and refrigerate for at least 1 hour or overnight. This allows the bread to soak up the custard mixture.
Preheat the Oven: When you’re ready to bake, preheat the oven to 350°F (175°C).
Bake the Casserole: Remove the casserole from the refrigerator (if chilled) and bake for 30-35 minutes or until the top is golden brown and the custard is set.
Step 4: Serve
Optional Caramelizing: If you want a crispy topping, sprinkle the granulated sugar over the top of the casserole and use a kitchen torch to caramelize it until golden.
Slice and Serve: Let the casserole cool for a few minutes before slicing. Serve warm with your favorite toppings, such as fresh fruit, maple syrup, or whipped cream.
Make-Ahead: This casserole is great for meal prep. You can prepare it the night before and bake it in the morning for a hassle-free breakfast.
Flavor Variations: Feel free to add mix-ins like chocolate chips, nuts, or berries for added flavor and texture.
Leftovers: Store any leftovers in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
