Overnight Cinnamon Apple French Toast Casserole

Overnight Cinnamon Apple French Toast Casserole is the perfect autumn breakfast to wake the family up to! 

Hey! Melanie here again from Garnish & Glaze. Fall is in the air! It’s getting cooler here on Long Island and the leaves are already turning and falling to the ground. I sure love this time of year and not just the because it’s the perfect sweater layering and boot wearing weather but there are also so many yummy comforting food to eat, like this Overnight Cinnamon Apple French Toast Casserole.

Guys, this is my new favorite French Toast Casserole, followed closely by my Overnight Coconut Almond French Toast Casserole! Seriously, your weekend weekend can’t get much better than wearing your jammies and eating a slice of this Overnight Cinnamon Apple French Toast Casserole soaked in maple syrup. Mmmmm! I just feel all warm and cozy inside just thinking about it.

This breakfast casserole is a cinch to make. Just cut up some day old challah bread and your favorite apples, pour a custard mixture over the top and let it all soak into the bread while you sleep. The next morning all you have to do is turn on the oven, mix 4 ingredients together to make the yummy streusel for the top and then bake. While it bakes you can snuggle back in bed, binge on Netflix, get ready for the day,… whatever.


When the the streusel is golden brown on top and middle is set, it’s breakfast time! Break out the powdered sugar and maple syrup for a scrumptious breakfast with the fam. The apples in this are perfectly cooked, just soft enough without being mushy. I used gala apples but you can really use any variety.

This is casserole is rather large so be prepared to feed many mouths or eat a lot… which you much might do because it’s that yummy. Enjoy!
