Health Benefits & Risks

Buying & Preparing
Mackerel is a flavorful, oily fish best enjoyed fresh due to its high oil content, which causes it to spoil quickly. Its rich, pronounced flavor makes it a favorite for those who appreciate bold seafood tastes.
Look for firm, shiny fish with clear eyes and a fresh ocean scent. Mackerel is excellent when fried, baked, grilled, or smoked. To mellow its strong flavor, remove the dark outer bands of meat along the midline before cooking. Its oily flesh lends itself well to robust preparations like smoking or grilling with marinades.
