Fish Sticks are pretty quick to deep fry and cook.
Cooking and deep frying fish sticks takes at most 3 minutes to cook fully.
Bring your deep fryer up to temperature and get the cooking oil up to 350 F degrees and then allow the fish sticks to be in the deep fryer for 3 minutes.
If the fish sticks are not done enough for you then you can cook them for another minute or so but any longer than 4 minutes then the fish sticks will burn.
I cook my fish sticks for 3 minutes in the deep fryer and that's long enough for me.
