Marinated mackerel with sweet and sour onions

Mackerel is a fatty fish that’s packed with omega-3 fatty acids, which can help reduce the risk of heart disease and stroke. It’s also a great source of vitamin D, vitamin B12, and selenium. Mackerel has a rich and distinctive flavor that pairs well with all sorts of different ingredients, from citrus fruits to bold spices. One of the best ways to enjoy mackerel is marinated in a flavorful mixture of seasonings and served with sweet and sour onions.

To make marinated mackerel with sweet and sour onions, start by preparing the marinade. Combine olive oil, lemon juice, soy sauce, honey, and a pinch of red pepper flakes in a small bowl. Whisk the ingredients together until they’re fully blended. This marinade has a great balance of sweet and sour flavors, with a bit of heat from the red pepper flakes.

Next, prepare the mackerel fillets by rinsing them under cold water and patting them dry with a paper towel. Place the fillets in a shallow dish and pour the marinade over them. Use a spoon to coat the fish evenly with the marinade. Cover the dish with plastic wrap and refrigerate for at least an hour, or up to four hours if you have the time.

While the mackerel is marinating, you can prepare the sweet and sour onions. Start by heating a tablespoon of olive oil in a large skillet over medium heat. Add sliced onions, a pinch of salt, and a tablespoon of balsamic vinegar to the skillet. Cook the onions for about ten minutes, stirring occasionally, until they’re lightly caramelized. Add a tablespoon of brown sugar and a splash of red wine vinegar to the skillet. Continue cooking the onions for another five minutes, until they’re soft and tender.

When the mackerel has finished marinating, preheat a grill or grill pan to medium-high heat. Remove the fish from the marinade, shaking off any excess liquid. Grill the mackerel fillets for about three minutes on each side, or until they’re cooked through and slightly charred.

To serve, arrange the grilled mackerel fillets on a platter and top with the sweet and sour onions. The onions add a nice contrast to the rich flavor of the mackerel, and the combination of sweet and sour flavors is absolutely delicious. This dish is perfect for a summer barbecue or a weeknight dinner when you want something healthy and flavorful.

In conclusion, marinated mackerel with sweet and sour onions is a delicious and healthy dish that’s perfect for any occasion. It’s packed with omega-3 fatty acids, vitamin D, and other important nutrients, and the sweet and sour onions are a delicious complement to the rich flavor of the mackerel. This dish is easy to prepare and sure to impress your guests. So next time you’re looking for a new recipe to try, give marinated mackerel with sweet and sour onions a try. You won’t be disappointed!
