Depending on the desired taste and texture, a mackerel fillet can be quickly pan fried, grilled or oven baked. Cooking mackerel is easy using one of these three simple methods, explains the Food Network.
To fry mackerel, add a small amount of cooking oil or butter to a pan over medium heat. Place the mackerel fillet skin side down, and season the facing side to taste. Cook for 5 minutes. Flip the fillet and cook for an additional 5 minutes until done.
To grill mackerel, coat the fillet with melted butter or cooking oil. Place the mackerel skin side down on a hot grill, and season the facing side to taste. Cook the fillet for approximately 5 minutes, or until the fish easily flakes.
To bake mackerel, coat a baking dish with cooking oil. Coat the fillet with melted butter to maintain moisture, and season the fish to taste. Cook the fillet in the oven at 325 degrees for 10 minutes.
