French Toast Casserole
Make your mornings special with this easy French Toast Casserole. It has everything you love about traditional French Toast, and is baked all in one pan!
When I was growing up, my older sisters did a lot of the cooking. They each had their own specialties, and my younger brother and I always looked forward to their meals.
One of our favorites is French Toast, and to this day my sister makes it better than anyone I know. Since we are separated by lots of land, I don’t get to scarf down her French Toast as much as I would like.
But I have found that no matter if you’re missing your family or simply just the food of your memories, sometimes the only solution is to head to the kitchen and get a little creative.
I’m telling you right now that this French Toast Casserole is so good, you may find yourself wanting it for not only breakfast, but also for your lunch, midday snack, dinner, and dessert as well!
You will make the bottom layer with brown sugar and melted butter, and it is just absolutely swoon-worthy!
Ingredients to make French Toast Casserole
- french bread
- butter
- brown sugar
- eggs
- milk
- vanilla extract
- cinnamon
- powdered sugar
How to Make French Toast Casserole – Step by Step
- You’ll start out with half a loaf of French Bread and then cut it into cubes. I am going to be a stickler for this one, because while you could substitute other breads, it really just won’t have that perfect flavor and texture. After you chop up the bread, then next melt some butter in a small sauce pan and stir in a cup of brown sugar. This is the bottom layer of your French Toast Casserole and it gives it an amazing caramelly flavor once it’s been baked.
- Next you’ll add in your bread cubes, then pour a mixture of eggs, milk, cinnamon, and vanilla over the top.
- Pop it into the oven and bake for about 30 minutes, and you are on your way to one of the most yummy breakfasts you’ll ever sink a fork in to! Really, I mean it!
Tips and Notes
Which bread is best for French Toast Casserole?
I prefer to use french bread, and it’s best if the bread is dry and not too soft. This allows it to soak up the yummy sauce from the casserole better and prevents the the french toast from becoming too soggy. If time allows, cut your french bread into cubes and place in a single layer on a cookie sheet over-night or for around 12 hours to help the bread dry out before baking.
You could also use sourdough, brioche, or Italian bread in this recipe, but like I said french bread is my favorite!
Can French Toast Casserole be Frozen?
Yes! Make the casserole in a freezer safe baking dish (such as a disposable aluminum foil pan) and bake as directed, then allow it to cool completely. Wrap in both plastic wrap and aluminum foil and freeze for up to three months. Allow the casserole to defrost completely in the refrigerator for roughly 24 hours before baking. Reheat the casserole, uncovered, at 350 degrees for about 30 minutes.
Can this be Made Ahead of Time?
Yes, and that’s one reason why I love it for the holidays! It makes a great Christmas morning breakfast because you can prepare it in advance and pop it in the oven to bake while you open presents! Simply prepare as directed up until the final baking step. Cover the unbaked casserole with plastic wrap and place in the refrigerator overnight, then bake as directed in the morning!
Gluten Free and Dairy Free Options
This recipe can be made with gluten free french bread, and can also be made dairy-free by substituting the butter and milk. You can replace the butter with either coconut oil or dairy free butter, and the milk with your favorite dairy free substitute like almond milk, coconut milk, or soy milk. All of these substitutions would be a 1:1 ratio.

I’m wondering if I can use 3 day old cinnamon raisin bagels
Super simple and tasty! I used unsalted butter (because that’s what I had), used up a 1/2 cup of leftover ricotta + whey and counted it as part of the dairy, and added a 1/4 tsp of almond extract. It was a solid B+ result, but just a little flat flavor-wise. I think using salted butter would have made a big difference.
Next time I could see adding a pinch or two of salt to the milk/egg mix, sliced almonds, and fruit (like diced dried apricots) to give it a pop. Maybe adding half and half in place of some of the milk or cubed cream cheese to up the “creaminess” factor?
Seriously, though, you will not be disappointed if you try this as written!
I’ve tried to read all the reviews but can’t seem to find an answer. Can I bake this then reheat it to serve the next day or possibly two days after originally baking it without compromising too much of the texture? I’d like to make this for a wedding brunch but would like to get it all ready and just be able to reheat it the next day (day after the wedding).
I appreciate any guidance, this looks delicious I just know it will be a busy wedding day and a late night. Not sure I’ll be able to get up early enough to prepare from start to bake, plus I need to transport to another location where ideally I can reheat this..
Thank you!
Hi! Yes you can definitely do that. I’d reheat it in the oven at a lower temp, around 300, until it’s warm.
Made this recently for family on our beach trip. Everyone loved it, even the picky uncle! Followed the directions exactly. Made the night before and just popped in the oven in the morning. Some added maple syrup others loved it just as is. I will make this again for sure
My granddaughter’s eyes lit up when she saw the casserole. Delicious french toast casserole recipe! I made it exactly as written. Thank you for this fantastic recipe.
This is amazing and so easy. Made with gluten free bread and almond milk. I might sub coconut milk next time for higher fat content but this was incredible. Will be making again and again!
Best French Toast Casserole recipe I have tried! It was delicious, came out perfectly, and was a big hit with our family. I made it the night before and used a little less than half of a 24-oz loaf of crusty sour dough bread (so it was about 12 oz of bread). I did set the bread slices out to dry for a few hours in the afternoon before assembling the casserole. This recipe is a keeper!
Sounds yummy but not sure the macros are right- I don’t believe that there are 48 G protein per serving
Rave reviews from our family! It’s now on regular rotation for events
So good!! And so nice I didn’t have to stand at a cooktop I could visit while it cooks. Thanks
Just made this for breakfast. I used a few days old cinnamon raisin bagels. Came out really good. I left out the last cinnamon and brown sugar toppings because I didn’t want it to be that sweet. Thank you for the recipe.
Can I freeze this before cooking?.& cook the day I thaw it
Yes, you can freeze it!
Amazing! My whole family loves this easy, sweet, French toast.
Dear Ashlyn, this was so delicious and easy! I made it for family that was visiting and every bit of it was eaten. I was dubious at what seemed to be such a small amount of bread (1/2 loaf of 1-lb. french bread) in a 13×9 pan but with the eggs and milk, the recipe puffs up like a giant souffle so if you want more, make another half recipe or so in a different baking dish.
I made the recipe exactly as written, including letting the bread pieces sit out overnight. Fabulous. Thank you for sharing this recipe.
Not sure where I made a mistake. Followed directions exactly. Mine turned out very tasty but the bread was a complete soggy mush.
Will try again. I really want this recipe to work for my family! I have 4 teen boys to feed every morning!
