Tips and Tricks To Make The Perfect Oven Roasted Spanish Mackerel:

  • To make the cooking process even easier, ask the guy at the fish counter to clean the fish and discard the head and tail.
  • When shopping for fresh mackerel make sure is does not have a strong odor, the eyes should be bright and clear, moist skin and shiny scales, to ensure you are getting the freshest fish.
  • The marinade in this recipe can be used either if you have a whole fish, fish filets or fish steaks.
  • I swear by marinades, no matter how good a fish is the marinade will make it a hundred times better, I and hubby use a very simple marinade, yet it tastes so fresh and it has the right amount of spiciness.
  • I prefer to use fresh fish over frozen, but frozen fish that has been thawed will work as well in this recipe.
  • Using fresh produce is key, fresh lemon juice, grape tomatoes etc and don’t skip the capers!
  • Do not discard the marinade, you want to use it for roasting the fish.
  • Make sure you don’t over-bake the fish, you want it juicy not dry, once the meat is white and tender it is ready to serve.
