Apple Cinnamon Bun Breakfast Casserole
Apple Cinnamon Bun Breakfast Casserole is the perfect sweet breakfast treat! Its cinnamon roll crust is covered with apple pie filling and topped with creamy eggs for the best start to your day.
Nothing makes me happier than an easy breakfast casserole. Meet the Apple Cinnamon Bun Breakfast Casserole: part sweet treat, part breakfast dream. This casserole is super filling and great to serve when you have company. I’ve made many varieties of breakfast casseroles in the past, but this was my first time using cinnamon buns as a base.
Now that I’ve got you thinking about dessert, try this Apple Cake with Butterscotch Sauce for an authentic apple dessert that’s rich and decadent with a homemade sauce!
Save time and use refrigerated cinnamon buns. I also used canned apple pie filling to keep things easy peasy. It’s bound together by a creamy egg mixture and bakes to a perfect golden brown. You don’t even need any extra toppings because it’s sweet enough on its own!

Yes, it’s almost like a dessert! If you wanted to serve it as dessert, you could. I prefer it first thing in the morning, though, as a sweet treat to wake up to. It smells so good while it’s baking in the oven!
How to Make Apple Cinnamon Bun Breakfast Casserole
- First, let’s prep! Preheat your oven to 350°F, and spray a 1.5-quart baking dish with cooking spray.
- Next, cut up your cinnamon rolls into bite-size pieces and spread them evenly across the bottom of the greased dish.
- Now, spread the apple pie filling over the cinnamon roll base. Make sure it’s even!
- Then, whisk your milk, eggs, salt, vanilla extract, and cinnamon in a large mixing bowl. Pour this mixture over the apple filling.
- For the topping, stir your brown sugar and cinnamon in a small bowl. Sprinkle it evenly over the egg mixture and cover the dish with foil.
- Finally, bake for half an hour, covered. Then, remove the foil and cook for about 30 minutes more or until the eggs have set. Serve immediately. Enjoy!
The easier the recipe, the better, at least in my books! Breakfast casseroles are one of my favorite recipes to wake up to. You can start the prep work the night before and finish the next day.
How to Make Ahead
No one wants to wake up and spend hours in the kitchen BEFORE breakfast. That’s just cruel.
To do this in advance, you want to keep the parts separate until baking time. If you have space in the fridge, you can cut the cinnamon rolls, finish the bottom layer in the baking dish, and leave it to chill. Let it sit out a little before baking to bring the dish back to room temperature.
You can whip the egg mixture together and refrigerate it overnight. If you’re using canned apple pie filling, you can leave it or refrigerate it if it’s opened. Assemble, bake, and you’re done!
How to Freeze
This recipe can be frozen, whether as a whole casserole or in one piece! It will last about 4 or 5 days in your refrigerator, but if you want to keep any leftovers longer than that, freeze them before then.
Make sure your casserole is in an airtight container with as little space as possible for freezer burn to develop. You can make individual servings for easy weekday breakfasts or a whole recipe for a surprise brunch.
This will last about 3 months in the freezer.
How to Reheat
Assuming you even have leftovers, you’ll want to eat this again soon. Because of the egg mixture, it can only safely sit out for about 2 hours, so make sure to refrigerate or freeze any leftovers ASAP.
I prefer reheating this in the oven over the microwave because the egg texture can get gummy. Set your oven to 350°F, cover, and reheat for about 15 minutes, then check the temperature. If you’re doing one piece, it will be faster than an entire dish.

Hi Stacie,
Do you think I can use my homemade cooked apples in place of canned apples? I really don’t like the texture of canned apples. Thanks
Yes, definitely!
I have to triple this dish for firemen. Could I bake it tonight & reheat since it has to be there very early in the morning….& will the taste & texture still taste good?
Thank you!
It should be fine!
Is it possible to make this the night before and refrigerate?
Yes, you can do that!
Here in Australia we can not get the Pillsbury Cinnamon Rolls, or any preformed dough like it, what else could you suggest we use?
I didn’t realize that! What about if you made your own homemade cinnamon rolls and used them in the recipe? It would be more work than the already ready to bake rolls, but it should work.
Hi there! Is it assumed that the cinnamon buns are already baked or will they still cook with the apple pie and egg ingredients? It just says to cut the buns into bite sized pieces…thanks!
No, it’s the Pillsbury Cinnamon Roll cans. You cut up the dough and it all bakes with the apple pie and the eggs. Sorry it wasn’t more clear!
What eggs?
If I want to make a bigger batch in a 9×13 glass dish how long should I bake for?
I would still do for an hour and then check it to see if it’s set or not. If not, then check every 10 minutes until it’s fully baked.
