Blueberry French Toast Casserole is what your family wants for breakfast! This easy-to-make overnight french toast bake can be prepared the night before and bakes in about an hour. Serve it for brunch this weekend.
I love breakfast casseroles. They are easy to make and can be prepped in advance. This sweet blueberry breakfast casserole is so decadent that you might think it's a dessert. But it's filled with wholesome fresh ingredients including eggs and blueberries.
The crumb topping elevates this French toast bake and I couldn't think of a better dish to serve for a special occasion brunch. Mother's Day, a special Saturday breakfast, Easter brunch or really anytime is perfect to make and serve this French toast recipe!
Ingredients/ Variations for Blueberry French Toast Casserole
- Bread - I often use cubed white or potato bread because we usually have these on hand. Brioche, challah, ciabatta, or whatever you have on hand will be tasty.
- Blueberries - Fresh fruit is what I prefer but you can use frozen blueberries (see paragraph below). You can also substitute another berry in season. Try pitted cherries, blackberries, or strawberries.
- Milk - We use whole milk but you can use 2%, half and half or even a combination of milk and cream. I wouldn't recommend 1% or skim milk for this oven french toast recipe because it won't be as decadent.
- Eggs - large eggs are the perfect size
- Bourbon - Optional but it adds a nice flavor and the alcohol is cooked out.
- Sugar - White sugar is added to the custard and brown sugar makes a lovely crumb topping.
- Flour - This helps to form the luscious crumbs on the French toast casserole.
- Butter - Gives the crumb topping a buttery flavor and holds the crumbs together.
- Salt - A pinch of salt can really elevate the flavor of the crumb topping and blueberry casserole.
How To Make Overnight French Toast Bake
- Mix together milk, eggs, vanilla, bourbon and white sugar in a bowl.
- Grease a baking dish and fill it with cubed bread and fresh blueberries.
- Gently mix to combine and pour the egg mixture over the bread then cover and refrigerate overnight.
- Mix together butter, flour, brown sugar and salt and sprinkle the mixture over the top of the casserole.
- Bake and serve. (See recipe card below for full instructions.)
I love making this overnight Blueberry French Toast Bake for brunch because it can be put together the night before. The bread soaks up the milk and egg liquid, giving it a firm custard texture after it is baked. I mix the crumb topping up right before the casserole goes in the oven but besides that there is very little work in the morning.
My secret ingredient that gives the casserole an extra burst of flavor is 2 tablespoons of Bourbon. It can be left out if you prefer not to use alcohol.
Fresh or Frozen Blueberries?
NJ is the Blueberry capital of the world so of course I prefer fresh blueberries. But if it's that time of year when I can't get them, I will substitute frozen berries. Since there will be a bit more liquid from the frozen berries you might need to bake the casserole 5 to 10 minutes longer.
Storing and Reheating Leftovers
The leftovers can be stored in the refrigerator for 2 to 3 days and reheated. Make sure to keep them in an air tight container.
Reheate any leftover French toast casserole in a baking dish in a 350 degrees heated oven until the Blueberry French toast is piping hot. You could also reheat pieces quickly in the microwave for 40 to 60 seconds or untuil hot. But the texture will not have a crisp outside.
I don't recommend freezing this breakfast casserole as the texture will be very soggy when reheated.
