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 had to use brioche because they were out of French bread, and I used vegan butter but it turned out delicious and I don’t like French toast. Great recipe!
Made this for a special brunch this morning – and it was a hit! Absolutely delicious. My only issue is that the brown sugar/butter bottom stuck. I buttered the glass dish well – but the bottom won’t come up. It’s like candy, though – delish (once you scrape it up)! Can you offer any advice for that issue? TIA
I have a question – instead of freezing what is left of the entire casserole in a pan – can you make up individual plastic bags and freeze them – this way you can have individual servings whenever you want them for breakfast – lunch or dinner – instead of reheating in oven – would a microwave work – recipe looks great – cannot wait to try it
Yes that is a great idea! I would thaw them overnight in the fridge and then heat in the microwave.
This is the most delicious breakfast! The whole family loves it.
This casserole was such a big hit this morning for breakfast! The family loved how delicious and yummy this recipe was. I’ll definitely make this again!
This is such an amazing day starter!! Everyone at my house loved it!
This looks SO good! Are there any other toppings that can be added?
This French Toast Casserole is most definitely an EPIC breakfast!
I didn’t think I could like french toast anymore. This casserole is amazing, and our go to for holidays.
I made this while on vacation at the beach. It was so easy and everyone raved about it.
Just wondering about the making the night before option! I was planning to make this for Father’s Day brunch and wanted to confirm: am I supposed to bake it then let it cool and refrigerate overnight and reheat in morning or have the first time I bake it be in the morning??
Thank you in advance!
Only bake it the one time!
I only have a baguette but it is still pretty soft and wider than most. Used this and will see how it turns out tomorrow. Do you think this will be ok?
Thanks!
Though you encourage using French loaf, can I use day old croissant instead?
I haven’t made this with croissants before so I’m not sure how it would turn out!
This was the best french toast casserole! I had 17 people for Mother’s Day brunch and this was a hit. I never made this before but it is now my go to for breakfast, brunch or even dinner, when we do breakfast for dinner. When I offered to do brunch this year I started googling for ideas and recipes and came across yours and I tested it out beforehand and we loved it. My daughter (13 yrs old) ate the leftovers for days and said it was even better. My guests raved. It was excellent. I used two loaves of french bread( and adjusted the other ingredients accordingly) because I wanted to make more. I had so many more other things but this was a favorite. The brown sugar and melted butter mixture made the dish! That was so yummy. It was this sweet, gooey, goodness. And it wasn’t too sweet. It was perfect. Some of us didn’t even use syrup. We added amaretto to the egg mixture too! We are definitely making this again when we have guests.
I added a few drops of almond extract to the butter and brown sugar..
Wow!
I made this, this morning for my son’s sleep over. I really didn’t want to share it with anyone. I wanted it all to myself!! It really is one of the most amazing breakfasts I’ve ever made! The brown sugar and butter on the bottom put it over the top good. Delicious! Thank you!
