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

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.

Great recipe, but more like a super sweet bread pudding to me than a fluffy French Toast. Be sure to generously butter your pan, and consider removing it from said pan while still warm. (I have it cooling in pieces on parchment right now.) The butter and brown sugar on the bottom caramelize and bubble into the bread, and it also sets up as caramel as it cools. I had half a loaf of homemade white bread that was too firm and dry for sandwiches and used it, as it made the 8 ounce requirement. Added a couple of homemade bagels as there was enough custard (my eggs were very large.) However I think adding the bread to the custard and then placing over the sugar would have been the way to go. Would I make it again? Yes, but for a special dessert, and i would use 6 well buttered ramekins. Its very good and I rated it 5*, but “too much” sugar and caramel for me as a breakfast item.
My family loved this. I toasted the bread cubes for two minutes in the preheated oven while spreading the brown sugar butter mixture in the pan, and they worked well. Thank you!
I made 1 1/2 times the recipe. I used 8 French Steak Rolls that we had left over, and added left over cinnamon honey butter to make up the butter.
My babies were craving French toast and this seemed so much better than cooking individual slices of toast. So glad I tried it! We were out of vanilla and we definitely didn’t have a loaf of French bread lying around, but we did have a package of leftover hotdog buns and some maple syrup to substitute. I toasted the buns in the air fryer and they worked great. The top baked nice and crispy, while the center was nice and custardy. Absolutely loved the brown sugar butter mixture on the bottom.
I used French bread. I followed it except used 1-1/2c milk and added 1 cup fresh blueberries. Baked at 400 degrees first 20 minutes , placed foil over it and then 425 degrees last 20 minutes. I made sausage patties too. I brought it to a brunch with friends and all was gone. Everyone loved! This recipe is a keeper!!
