Air Fryer Breakfast Casserole. How to make a delicious breakfast casserole in the air fryer that is loaded with sausages, bread, cheese, and peppers. Ideal for a make ahead breakfast casserole that is easy to prep, cook in the air fryer and then reheat in the air fryer later.
Air Fryer Breakfast Casserole
I just started writing about this air fryer breakfast casserole and I am starving hungry, wishing that I had some more of it to eat right now!
To my surprise Dominic shouted me to let me know lunch was ready and he had made a breakfast casserole for us all. Talk about my guardian angel.
What I love about an air fryer breakfast casserole is that it can be loaded with whatever foods you want.
As long as you avoid watery vegetables such as pumpkin or zucchini you are good.
- Don’t want sausages then add bacon
- Want a vegetarian version then add more vegetables
- Go low carb by focusing on meats and low carb seasonal vegetables
- Got some spare stale bread, then add it in
- Keep it Paleo by avoiding cheese and bread
What I love about a breakfast casserole is that it can also be used to get rid of spare and unwanted vegetables, bread, and eggs making it great for food waste.
While a breakfast casserole is often associated with family gatherings and Thanksgiving or Christmas, I love it as one of those great fridge or pantry clear outs.
Or even better, if you are having it for Christmas, then use up all those foods you bought in for Christmas that is not going to get used. Or make one the day after Christmas with some of your spare slow cooker stuffing for turkey.
The possibilities when it comes to a breakfast casserole are endless.
What Is A Breakfast Casserole?
If you are not American the chances are, you will not have heard of a breakfast casserole. In fact, I only heard of it after being introduced to it by one of our readers.
My first thought when he described a breakfast casserole to me, is that it is similar to our air fryer frittata.
Air fryer frittata, egg casserole, breakfast casserole, or even the Spanish potato omelette are all similar meals that you can make in the air fryer.
The breakfast casserole ingredients are:
If you were British would probably call it a sausage and cheese frittata or a crustless sausage quiche. Just like the Spanish potato omelette it is very heavy on eggs and this keeps you full for hours. Plus, this is excellent for saving you money because you would only need to serve one small slice to each guest for breakfast or brunch.
There are about a zillion variations of a breakfast casserole and many go beyond eggs, cheese, sausage, and onion.
For example, I see many with peppers, bread, sweet potatoes and hash browns.
Can You Cook Casseroles In An Air Fryer?
Yes you can. Casseroles are FANTASTIC in the air fryer, if you use the air fryer to its full potential.
The way I see air fryer casseroles being cooked wrong is that they start on the stove and then end in the air fryer. Essentially meaning the air fryer is ONLY used as a grill and not for the whole casserole.
You want to sauté your casserole filling in the air fryer, mix in eggs and then finish the breakfast casserole in an air fryer friendly baking pan.
Reheat Breakfast Casserole
As well as sautéing the casserole and baking the casserole in the air fryer, you can also reheat the breakfast casserole.
What I recommend for reheating a breakfast casserole in the air fryer is chopping it into casserole slices and then loading up to 3 at a time in your air fryer basket.
The ideal reheating cook time is JUST 4 minutes at a 160c/320f temperature.
Add your favourite sauce and you have warm breakfast casserole.
Breakfast Casserole In An Air Fryer
The quick version of air fryer breakfast casserole goes as follows:
- Prep sausages and vegetables and air fry.
- Load air fryer ingredients into air fryer casserole dishes.
- Toss in egg and other ingredients.
- Load dishes into the air fryer.
- Air fry until fully cooked.
There is a little more to it than that, but those are the simple basics!
Make Ahead Breakfast Casserole
You can of course make ahead your breakfast casserole and store it in the fridge for up to 5 days, or 7 days if it is meat free.
You have three options:
- Sauté your vegetables and mix with eggs and then fridge for the main air fryer bake when you need it.
- Fully cook your breakfast casserole then reheat when you want to eat the slices.
- Make ahead and then slice up and freeze. Then you can reheat from the freezer whenever you need some.
When Do You Know When Breakfast Casserole Is Done?
Place a cocktail stick into the centre of the breakfast casserole and if it comes out clean it is DONE.
Then if in doubt, slice a knife through the centre and if it slices well without any water coming away it is DONE.
Can You Freeze Breakfast Casserole?
Yes you can freeze breakfast casserole. Slice it up ready for how you would reheat it and then load the slices onto a flat tray or chopping board.
Lay in the freeze like this for about an hour.
Then transfer your breakfast casserole slices into a freezer bag.
It will now keep its shape without the breakfast casserole slices sticking together and take up less room in your freezer.
Air Fryer Breakfast Casserole
- Peel and dice a sweet potato into cubes. Toss in a bowl in extra virgin olive oil with salt, pepper, garlic, and oregano.
- Place the sweet potatoes in the air fryer. Diced mixed peppers, chop sausages into quarters and dice your bacon.
- Add the sausages, peppers, and bacon over your sweet potatoes. Air fry for 15 minutes at 160c/320f.
- Slice and cube your bread while the air fryer is cooking and beat in a mixing jug your eggs with a little extra salt and pepper and some parsley. Dice your spring onion.
- When the air fryer beeps check on the potatoes. You need to get a fork through them. If you can’t, cook for another 2-3 minutes. Stir the air fryer basket, add in your spring onions, and cook for a further 5 minutes on the same cooking time and temp.
- Using your planned baking pans, load the contents of the air fryer over two of them. Add cheese and bread and mix. Pour egg mixture over them and they are now ready for the final air fry.
- Load your baking pan into the air fryer and cook for 160c/320f for 25 minutes. If you are cooking two, cook one first, then the other. Put a cocktail stick through the centre and if it comes out clean, then it is done.
Can’t make it now? Then pin it for later!
