Apple Brioche French Toast Casserole


Sharing is caring!

Make this Apple Brioche French Toast Casserole for your next brunch at home! Packed with apples and delicious brioche bread, this recipe will be an instant family favorite. 

I'm kicking 2021 off by sharing two recipes I've been making for a LONG time. First, these easy Baked Fish Tacos. And today, this incredibly delicious, simple, Apple Brioche French Toast Casserole!

Apple Brioche French Toast Casserole

This Apple Brioche French Toast uses my favorite bread; brioche! But, you don't have to use brioche. You can use french bread, challah, or sourdough. This overnight french toast casserole recipe is GREAT for using up slightly stale bread, so use whatever bread you have!

The bread that you use in this recipe is versatile, and so is the fruit! I love using apples because I almost always have them on hand, but you can use this recipe as the base and substitute many other kinds of fruit. Blueberries, raspberries, blackberries, pears and even bananas are all fair game as substitutes!

If you're able to, prep this Apple Brioche French Toast Casserole the night before and pop it in the fridge. Having it sit overnight is ideal, as it gives the bread time to soak up all the flavors! If you can't let it sit overnight, allow it to sit at least one hour before baking!

I love serving this overnight french toast casserole to guests. They love it! Pair with a simple egg casserole like this Tator Tot Breakfast Casserole or Breakfast Casserole with Bacon! You could also make these easy little Mini Egg Muffins with Bacon and Cheddar or a simple pan of scrambled eggs.
