Fish can be cooked in a deep fryer.
You can cook fish in a skillet or deep fryer and either way the fish will turn out just fine.
I have always cooked fish in my deep fryer and it makes for great deep fried fish.
I like to bread the fish and then cook it in the deep fryer like you can bread chicken and deep fry the breaded chicken you can deep fry the breaded fish.
Although you can cook fish in the deep fryer without breading it if you want too.
Cooking fish in a deep fryer takes between 5 to 8 minutes depending on the size of fish you're cooking.
Get the oil hot and then lower the basket of fish into the hot oil slowly and cook it for 5 to 8 minutes.
For me cooking the fish in the deep fryer for 5 minutes is good enough.
