Mackerel fish is widely available, relatively inexpensive and very quick to cook. This flavorful mackerel fillet with a beautifully crisp skin make a delicious and quick meal.

When choosing this Mackerel fish, you want to buy fresh fillets with skin on. Leaving the skin on not only provides the crispiness, but also helps to hold the fillet together as well as adding good fats.
