Wash the fish fillets and pat dry, drizzle with a little lemon juice. Salt and pepper on both sides.
Put the olive oil in an ovenproof dish, put the fish in it and sprinkle with chopped garlic and parsley. Place a few flakes of butter on top and cook in the oven preheated to 180 ° C for about 15 minutes. The time and temperature information is of course dependent on the size of the fish fillet and your oven.
Tastes good with rosemary potatoes and green salad
