Ingredients

- Multigrain bread: I use multigrain bread to create a healthier version of the classic French toast with a nutrient-packed alternative to challah or brioche bread. Enjoy all the benefits of fiber and vitamins.
- Eggs and egg whites: This recipe uses a combination of both eggs and liquid egg whites to keep it heart healthy and lower on fat. For convenience, try using liquid egg whites from the carton for easy preparation.
- Milk: I used skim milk to get the creaminess flavor without the excess calories. Feel free to use any milk you like, including dairy free alternatives!
- Greek yogurt: I used the brand Oikos Triple Zero (vanilla flavor) to pump up the protein content! It blends in so well and adds to the creamy flavor.
- Blueberries: The blueberries add a nice pop of color to the french toast, as well as nutritional benefits of antioxidants! You can swap for whatever fruit you prefer.
- Baking ingredients and spices- I always use vanilla extract, cinnamon, and nutmeg when I make french toast to elevate the taste!
- Maple syrup: I used sugar free maple syrup to drizzle when ready to eat!

How to Make Blueberry French Toast Casserole
- Enjoy the deliciousness of french toast with none of the fuss! French toast casserole is your go-to breakfast treat that's unbelievably easy to make and eat.
- Spray a 9×13 baking dish with cooking spray. Arrange the bread pieces in a single layer in the baking dish. Sprinkle 1/2 of the blueberries, then add the remaining bread on top.
- In a large bowl, whisk together the eggs, egg whites, milk, greek yogurt, syrup, vanilla, cinnamon, and nutmeg. Pour the egg mixture over the bread in the baking dish, spreading it around so the liquid saturates the bread. Sprinkle the remaining blueberries over the top. Cover and refrigerate overnight.
- When ready to bake: Preheat the oven to 350 degrees F. Uncover the baking dish and bake for 35-45 minutes or until baked throughout. Cover with aluminum foil if it still needs longer and you wish to not brown the top anymore.
- Slice into 8 servings and serve warm drizzled with syrup, if desired. Enjoy!






Swaps or Alternatives
If you're avoiding dairy but still want to enjoy this delicious recipe, simply swap out the milk and yogurt for your preferred alternative products like soymilk, almond milk, oatmilk, etc. To make this casserole gluten free, substitute your favorite gluten free bread! Keep in mind that nutrition information may vary based on your selection.
Quick Tip(s)
To make the perfect French toast, it’s helpful to use day-old bread to prevent it from being soggy. The main benefit of this is that the dryer bread will more easily soak up the custard mix for a delicious casserole! If you only have fresh bread, it may be beneficial to dry it out yourself. You can do this by placing your cubed bread on a sheet pan and baking at 350 for 10 minutes until lightly dried. Then use it in the recipe as directed!
Want to bring this casserole to your next brunch get together? Instead of a 9×13 dish, try making this recipe in a muffin tin. Each person will have their own individual french toast cup, plus you can more easily change up the toppings! Prepare the recipe as directed, place in muffin tins, and bake at 350 for 25-30 minutes!
FAQs
Can I use frozen berries?
Absolutely! Frozen berries are a great, inexpensive item to keep stocked in your freezer when it’s not summertime. If using frozen berries, you don't even have to thaw them- just brush off any extra ice and use as directed in the recipe.
What other toppings can I use?
No worries if you don’t like blueberries, this recipe can work with any other fruit or topping! Try using diced apples or pears for a fall themed casserole, or knix the fruit and use chocolate chips instead for a dessert style casserole!
What should I serve with the casserole?
I love pairing this casserole with even more fresh berries, chicken sausage, bacon, or greek yogurt!
How do I store Blueberry French Toast Casserole?
To store your casserole, refrigerate in an airtight container for up to 4 days. When ready to eat, you can reheat leftovers in the oven at 350 degrees F till warmed through. You may also reheat in the microwave if in a rush!
