French Toast Casserole

One of my favorite breakfasts to this day is French Toast! It is so easy to make and filled with so much flavor. The problem with traditional French Toast is that by the time you make enough for everyone the first person to get theirs is done by the time you sit down. 

That is why I am a huge fan of French Toast Casserole. It is loaded with flavor and is the perfect meal to all sit-down and enjoy together. Not only that, but you can easily prepare it the night before for a stress-free morning.

What will I need to make French Toast Casserole

You will need the following ingredients:

• Brioche bread: I used Sara Lee Artisan Brioche bread however you can use any Brioche bread you like. I do recommend a thick-cut bread or it may not hold up well to the liquid. 
• Lemon curd: I used a store-bought lemon curd but if you have a lemon curd recipe that you love you can certainly use that instead. 
• Dark brown sugar: You can use light brown sugar in a pinch, though it is a little sweeter so the flavor will change slightly. 
• Cinnamon
• Large eggs
• Half and half: You can use 1 cup whole milk and 1 cup heavy cream or replace all of the half and half with a milk of your choice, but be aware the final consistency of the casserole may be a little different. 
• Vanilla

How to Make French Toast Casserole

• Preheat the oven to 350 degrees Fahrenheit and grease a 9×13 inch baking dish with cooking spray.
• Take out the bread slices and use a butter knife to spread 1 Tablespoon of lemon curd on each of 7 of the slices.

• Top each slice with one of the slices that does not have lemon curd, making 7 “lemon curd sandwiches”. 

• Use a cutting board and sharp knife to cut the sandwiches into cubes and place them in the prepared baking dish. 

• In a medium-sized mixing bowl whisk together the eggs and then add in the half and half vanilla, cinnamon, and 3 Tablespoons of the dark brown sugar. Whisk until you have a smooth mixture. 

• Pour the egg mixture over the cubes in the baking dish making sure the bread is evenly soaked with liquid. 

• Sprinkle the remaining dark brown sugar evenly over the top of the casserole. 

• Bake for 55-65 minutes or until the casserole begins to get golden brown on top, has puffed up and the center is firm to the touch.  

• Remove from the oven and allow to cool 10-15 minutes before cutting and serving warm with fresh fruit and syrup, optional.

Tips Tricks and FAQs

• Be sure you use stale bread to help soak up the egg mixture. 
• Heavy bakery bread works best for this recipe.          
• Feel free to add toppings. Try orange zest or craisins to the top!      
• You can use non-dairy milk if you prefer. 

Reheating

You will want to reheat your casserole at 350 degrees in the oven for about 20 to 30 minutes or until warm. This helps keep the crispy top that we all love. 

You can reheat this in the microwave, but it becomes very soft.
