Overnight Apple Streusel French Toast Casserole

It's that time of year when the hustle and bustle of the school year begins and we try get back into school mode. If you're a parent of school-age children, you likely know what I mean. This year I will be shuffling all three of my children to school five days each week. That’s a lot of shuffling!

So when it comes to morning routines, I will do anything to save time in the morning. Besides picking out clothes the night before and packing lunches, I will often prep breakfast ahead of time.

That’s when make-ahead recipes like this Overnight Apple Streusel French Toast Casserole come in handy. I will typically make this over the weekend and just reheat it in the morning for a delicious warm breakfast. Of course, this casserole would also be the perfect dish to serve for a holiday brunch as well.

The addition of cubed apples in this recipe is the perfect addition to the French toast casserole. I love adding Michigan apples to tons of baked recipes since they complement just about any dish quite nicely. Here are a few of my other favorite baked apple dishes: Rhubarb Apple Cinnamon Muffins, Baked Apple Cinnamon Dumplings, and these Apple and Cranberry Scones. Now time to get baking!
