Fry the cod fillets in the oven. It's as fast as baked cod with vegetables (recipe HERE). But if we usually fry in vegetable oil, then cook the cod in the oven may be in the melted butter. This will give the fish a very different taste.
Also, the taste of cod fillet, baked in the oven,It will depend on the spices that you choose to cook. I propose to use white pepper and sweet paprika powder. If desired, add black pepper and a little chopped parsley (do not put a lot of it, otherwise it can burn slightly in the oven).
