HOW TO MAKE OVERNIGHT BLUEBERRY CRUMBLE FRENCH TOAST 

The secret to great french toast is in the bread. I love brioche because it’s the perfect amount of sweet and buttery, making it perfect for french toast! Cut the brioche into cubes and add it to a big mixing bowl. Then add a full pint of fresh blueberries and mix it together with the brioche. The bigger and sweeter the blueberries the better! 

Next, whisk together, eggs, milk vanilla and salt. Pour the egg mixture over the bread and blueberries and mix until all the bread is saturated. Transfer the mixture to a greased baking dish. Cover the dish and put it in the refrigerator overnight. This allows time for the bread time to soak up the creamy egg mixture.

The next morning, take the french toast out of the fridge. Then preheat the oven while you make the crumble topping. The topping is made with flour, oats, brown sugar and softened butter. Combine the flour, oats and brown sugar in a small bowl, then add the soften butter, use a fork to mix until the butter is fully incorporated. Sprinkle the crumble evenly over the french toast. Put the casserole in the oven to bake for about 35 minutes. 

Let set for about 5 minutes and then serve the french toast warm. It’s delicious on it’s own or with some warm maple syrup!
