Frequently Asked Questions

What size air fryer is best to use?

I made this chicken fried rice in my smallish 6qt basket air fryer. The dish I used meant that I had to remove the basket and place it directly into the basket base, but it still came out great. This recipe will easily serve four for breakfast.

What dish do you cook the casserole in?

Any dish that you would put in the oven can be used in the air fryer, to be safe, use one that is oven proof up to 420F. I used my 7.5 inch Staub casserole dish which worked perfectly.

Small metal tins and pans will also work well, but you may need to grease them or line them so that the eggs don't stick.

Can you oven bake it?

If you don't have an air fryer, you can easily bake this in the oven instead. Saute the veggies and sausage on the stovetop before adding to a casserole dish and baking in the oven at 380F for around 40 minutes.

Serving Suggestions

This air fryer breakfast casserole is perfect by itself for breakfast, but you can easily serve it for brunch, lunch or dinner with veggie, salad or potato sides for a fuller meal. Try it with these favorites:

Make ahead, Storage and Reheating

Make this cheesy sausage casserole once and enjoy it throughout the week! Once baked, let it cool completely before covering and storing in the fridge. It will keep well for up to 4 days. You can eat it cold, or reheat it in the air fryer at 360F for 3 to 5 minutes to serve.

This is also freezer friendly and will keep well for up to 3 months. Reheat right from frozen at 320F for 10 to 15 minutes.

Recipe Notes and Tips

Don't be tempted to try and cook this quicker on a high heat. If you do this, the top will get super hard and crispy and the bottom will not be set- learn from my mistakes!
Depending on what you cook the egg casserole in, you may need to lightly oil the surface of it so that the eggs don't stick.
As it is, this recipe is super tasty, but feel free to mix up the ingredients to suit your tastes!
For best results, let the air fried casserole sit for 5 minutes before cutting into it. This will allow any liquid egg to set.
