This is one of my favorite weeknight dinners because it comes together in under an hour and tastes like you spent all day cooking. Fresh mackerel is packed with omega 3 fatty acids that are wonderful for your heart and brain, plus it's incredibly affordable. The grilled fish pairs beautifully with caramelized plantains, and that bright cilantro lime sauce ties everything together perfectly. The best part? You only need basic equipment and ingredients you probably already have in your kitchen. Trust me, this dish will become a regular rotation at your dinner table.

Instructions
- 1
Pat the mackerel fillets dry with paper towels and season both sides generously with sea salt, black pepper, and smoked paprika. Let sit for 10 minutes to allow flavors to penetrate.
Tip: Dry fish prevents sticking on the grill and helps achieve a better crust.
- 2
Preheat your grill to medium-high heat (around 400°F). Brush the grates lightly with oil to prevent sticking.
Tip: A properly oiled grill is essential for getting those beautiful char marks.

In a small blender or food processor, combine chopped cilantro, minced garlic, minced jalapeño, lime juice, 2 tablespoons of olive oil, and water. Blend until smooth. Season with salt and pepper to taste. Transfer to a serving bowl and set aside.
Tip: Make the sauce while the grill heats up to save time.
- 4
Brush the plantain rounds on both sides with the remaining olive oil and season lightly with salt and pepper. Place on the grill and cook for 3-4 minutes per side until golden brown and caramelized. Transfer to a platter.
Tip: Don't flip the plantains too early; let them develop a nice caramelized crust for better flavor.
- 5
Place mackerel fillets skin-side down on the hot grill. Cook for 5-6 minutes without moving them, allowing the skin to crisp up.
Tip: Resist the urge to move the fish around; it will release naturally when ready to flip.
- 6
Carefully flip the mackerel fillets and cook the other side for 3-4 minutes until the flesh is opaque and flakes easily with a fork.
Tip: Mackerel is a delicate fish, so handle gently to avoid breaking the fillets.
- 7
Assemble the plates by arranging plantain rounds and red onion slices as a base. Top with a grilled mackerel fillet, skin-side up.
Tip: The crispy skin is the best part—keep it facing up for visual appeal.
- 8
Drizzle the cilantro-lime sauce generously over each mackerel fillet and plantains. Serve immediately while everything is warm and the skin is still crispy.
Tip: Serve immediately after plating for the best texture contrast between crispy skin and tender flesh.
