Rinse and pat dry the fish fillets with a piece of paper towel.

Beat the egg with a fork in a deep plate.

Pour breadcrumbs onto a flat plate and season with salt and pepper.

Dip the fish fillets first in the beaten egg and then in the breadcrumbs. Make sure the fish is completely covered, and feel free to sprinkle a little extra breadcrumbs over the fish.

Heat butter and oil in a pan, let it sizzle and fry the fish for 2-3 minutes on each side over medium heat.

Turn the fillets only once during frying, so you don't damage the delicious breading.

Also, do not fry the fish for too long, as it can easily become boring and dry.

Serve the fried fish fillets with boiled potatoes, lemon wedges, and some melted butter.

A fresh raw salad of grated carrots and apples with a dressing of orange juice also tastes really good with the fish.
