Pat the fillets dry with paper towels and season both sides with the salt and pepper.
Spread the flour on a plate, press each fillet into it on both sides and shake off the excess.
Heat the oil in a large frying pan over medium-high heat until it shimmers.
Lay the fillets in the pan and fry for 3-4 minutes without moving them, until the underside is golden.
Turn the fillets, add the butter and fry for 2-3 minutes more, spooning the foaming butter over the fish, until it flakes easily.
Drain briefly on paper towels, scatter with the parsley and serve with lemon wedges.
