PRO TIPS FOR MAKING BLUEBERRY FRENCH TOAST CASSEROLE

  • The secret to a great blueberry French toast bake is the right ratio of bread to custard mixture so that you can get the perfect texture. Follow the instructions below to get the right ratio.
  • If you don’t bake the assembled casserole right away and leave it in the refrigerator, you need to add 5-10 more baking time.
  • If you love cream cheese as much as I do, you can easily turn this recipe into French toast baked with cream cheese. Just swap out the butter for the same amount of cream cheese and you will get a creamier consistency!
  • Can I Use Frozen Blueberries for this Recipe? Yes, absolutely! Just defrost and drain them first before adding to your casserole.
    What’s the Best Way to Reheat this Casserole? Bake it in the oven at 350°F for 10-15 minutes until cooked through.

HOW TO MAKE BLUEBERRY FRENCH TOAST 

  • Cut bread into 1-inch cubes and add them into a baking dish.
  • Sprinkle blueberries on top.
  • Mix together eggs, milk, melted butter, cinnamon, vanilla, sugar and salt.
  • Pour the mixture evenly over the cubed bread and blueberries.
  • Bake for 35-40 minutes.
  • Remove from the oven and cool for 5 minutes.

You can assemble everything the night before and bake the French toast breakfast casserole the next morning!

WHAT KIND OF BREAD TO USE FOR FRENCH TOAST CASSEROLE

Since the bread is the base of this overnight French toast, it’s important to use high-quality bread that can stand up well and doesn’t get mushy! Bread such as brioche, challah, French loaf, and sourdough works well for this recipe. 

MAKE AHEAD FRENCH TOAST CASSEROLE

Although you can bake it right away, I prefer to cover it tightly with plastic wrap and refrigerate it overnight. The bread cube will soak up the mixture, resulting in a more custardy and delicious blueberry breakfast casserole!

OVERNIGHT FRENCH TOAST BAKED IN THE OVEN

Heat the oven to 350°F. If you bake it immediately after assembling them, it will take about 35-45 minutes. If you leave it overnight in the refrigerator and bake it the next morning, you need to bake it for about 40-50 minutes until the center is firm and the surface is lightly brown. 

Blueberry French toast casserole can be served warm or at room temperature. For leftovers, you can cover it tightly and store it in your refrigerator for up to 3 days. You can also freeze your French toast casserole for up to 3 months.

    This recipe was so yummy! I did make some alternative adjustments because of dairy and substituted Almond milk . I made it and immediately baked it. My leftovers I will have tomorrow morning after it has sat overnight and top with a spoonful of Vanilla Greek yogurt and Turkey bacon on the side.
