This Overnight Blueberry Crumble French Toast is an easy, make-ahead summer breakfast casserole. Gooey french toast packed full of fresh blueberries and topped with an irresistible brown sugar crumb topping! 



Blueberry French Toast

1 loaf brioche bread

1 pint blueberries

2 cups whole milk

6 eggs

1 tsp vanilla extract

pinch of salt

Crumble Topping

1/4 cup white all-purpose flour

1/3 cup rolled oats

2/3 cup brown sugar

4 tbsp unsalted butter, soft but not melted

pinch of salt


Blueberry French Toast

Slice the bread into cubes

Add the bread and the blueberries to a large bowl

In a small bowl whisk together the milk, eggs, vanilla extract and salt

Pour the egg mixture over the bread and blueberries in the large bowl, mix until all the bread is saturated

Spray an 8 1/2″ X 11″ baking dish with non-stick spray

Transfer the bread mixture to the baking dish

Cover and place in the refrigerator overnight*

In the morning, take the french toast out of the refrigerator

Pre-heat oven to 350°F

In a small bowl add the flour, oats, brown sugar and salt, mix to combine

Add the butter and use a fork to incorporate it with the sugar mixture

Using clean hands, crumble the mixture evenly over top of the french toast

Bake for 35-40 minutes**

Let set 5 minutes before serving with maple syrup


*overnight is best, but a minimum of 4 hours will work

**the longer you bake the drier the french toast will be, so adjust time depending on how “gooey” you like your french toast
