This Overnight French Toast Casserole is the perfect, easy, make-ahead breakfast that has all of the flavors of your favorite French toast!

Overnight French Toast Casserole
I love French toast. I always have. And I love to make it, but it can be time consuming. Until now of course. Enter The Greek Yogurt Cookbook...
The Greek yogurt not only adds some protein but it also makes it creamy without all of the extra fat and calories. This overnight French toast casserole is lightened up and simple to make.
When I was writing the "Breakfast and Brunch" chapter for The Greek Yogurt Cookbook, I knew I had to make some type of French toast. Well I did, and not only is it ridiculously delicious, but it's so easy to make. Who doesn't love a dish that you can make ahead? This casserole recipe will be one that you make many times. And everyone you make it for will thank you.
I have made this for almost every special occasion in the Kelly house because it's one of those rare dishes that everyone loves!
If you are looking for some other healthy breakfast recipes, you will love these Low Carb Blueberry Scones, Chocolate Peppermint Muffins and this Cranberry Biscotti.They would be even more yummy with some Low Carb Bulletproof Hot Chocolate, Apple Chai Latte or this Chamomile Latte!
Also, my cookbooks are both on sale now and would make a great gift! The Everything Wheat Free Diet Cookbook and The Greek Yogurt Cookbook are both the lowest prices I have seen!

Overnight French Toast Casserole
Ingredients
- 1 loaf stale bread
- 5 whole organic cage-free eggs

Instructions
- Spray a 9" × 13" casserole dish with organic nonstick cooking spray.
- 2. Tear bread into pieces and spread them throughout the casserole dish in an even layer.
- 3. In a large bowl, mix eggs, egg whites, Greek yogurt, milk, and maple syrup. Mix very well until smooth and thoroughly combined. Pour egg mixture completely over bread.
- 4. In a small bowl, mix butter, brown sugar, cinnamon, flour, and pecans, if using. Mix until all ingredients are combined, even if still lumpy.
- 5. Sprinkle the butter mixture on top of the bread. Cover and refrigerate overnight. If cooking the same day, make sure to refrigerate at least 30 minutes before baking.
- 6. In the morning, preheat the oven to 350°F. Bake for 45 minutes until golden brown and the middle of the dish is set. Serve immediately with maple syrup, if desired.

Erin @ The Spiffy Cookie says
I love Greek yogurt in all things! Great idea to use it in this casserole. What a yummy breakfast.
Sandy says
Can you use regular brown sugar?
lauren says
Instead of the maple syrup? It might have a different texture, I've never tried it. I am sure it would still taste great, let me know how you like it 🙂 Thanks Sandy!
Judith says
Flour? What am I missing here? I went to this site for wheat-free recipes.
lauren says
Hi Judith! I did write a wheat-free cookbook, but not all my recipes are wheat-free. This recipe is actually from another cookbook I wrote, The Greek Yogurt Cookbook. You can easily make this gluten and whet free by using gluten free AP flour and gluten free bread. Thanks for stopping by!
Kathy O'Neill says
I bought several copies of The Greek Yogurt Cookbooks to give as Christmas gifts and my husband made the Overnight French Toast Casserole on Christmas Eve. On Christmas morning he baked it and it was a hit with my family!! The only downside was there were NO leftovers. I am looking forward to trying more recipes this week.
lauren says
YAY!! I also made the Overnight French Toast Casserole for Christmas morning and no leftovers here either 😉 Thanks os much for letting me know Kathy, you made my day!
