Melt the butter in a frying pan.

Add in half the minced garlic to the pan.

Place the cod filets into the pan and cook on medium to high heat. Sprinkle with salt and pepper.

As the fish cooks, it’ll turn from translucent to a solid white color. Wait for the white color to creep half-way up the side of the fish and then flip the fish and add the rest of the minced garlic. Cook until the whole filet turns a solid white color (it should also flake easily).
