How long does it take to deep fry fish in a deep fryer? Fry the fish, two or three pieces at a time, in the hot oil until the coating is golden and fish begins to flake when tested with a fork, turning once. This takes about 3 or 4 minutes per batch. Drain the deep-fried fish on paper towels, flipping the fillets to drain both sides.
