- shredded cheddar cheese - you can also add in some mozzarella and a little cream cheese.

I also used the casserole/cake pan that comes in the Cosori accessories package you can find here. You can also use any deep dish oven-safe pan that will fit into your air fryer.

I make this but I use a chicken instead of beef. To me it taste better. Just take out the sour cream and use cream of chicken soup. Roltel Doritos I use the spicy cheese ones lol milk or heavy cream and shredded cheese mmmm

Can this be made directly in the basket of the air fryer if I don’t have a casserole pan?
You will need to have some sort of dish to place in the air fryer for this recipe. Otherwise it will seep through the grates.
