Main Ingredients

  • 2 whole mackerel fillets (or 4 smaller fillets)
  • 1½ teaspoons sea salt

Garnishes

  • 1 cup grated daikon radish
  • Lemon or sudachi wedges
  • Thinly sliced green onions
  • Fresh parsley (optional)

For Serving

  • Steamed Japanese short-grain rice

Kitchen Equipment

  • Grill, grill pan, or broiler
  • Baking tray (if using an oven)
  • Wire rack
  • Paper towels
  • Tongs
  • Serving plates

Instructions

Step 1: Prepare the Fish

Pat the mackerel fillets dry with paper towels.

Sprinkle both sides evenly with sea salt.

Let the fish rest for 20–30 minutes. This helps remove excess moisture and enhances the flavor.

Pat the fillets dry once more before grilling.

Step 2: Preheat the Grill

Heat a grill, grill pan, or broiler to medium-high heat.

Lightly oil the grill grate if needed to prevent sticking.

Step 3: Grill the Mackerel

Place the fillets skin-side down.

Grill for 5–7 minutes, depending on thickness.

Carefully turn the fillets over and cook for another 3–5 minutes until the flesh is opaque and flakes easily with a fork.

If using a broiler, cook until the skin is crisp and lightly browned.

Step 4: Prepare the Garnishes

Grate the daikon radish and gently squeeze out excess liquid.

Slice the green onions and prepare the lemon wedges.

Step 5: Serve

Transfer the grilled mackerel to serving plates.

Serve with:

  • Grated daikon radish
  • Lemon or sudachi wedges
  • Steamed rice
  • Miso soup
  • Pickled vegetables

A squeeze of citrus over the fish adds a refreshing finish.

Tips for Perfect Grilled Mackerel

Salt the Fish Ahead

Allowing the fish to rest after salting removes excess moisture and intensifies its natural flavor.

Cook Skin-Side First

Starting with the skin-side down helps create a crispy texture while protecting the delicate flesh.

Avoid Overcooking

Mackerel is naturally rich in oils, but overcooking can dry it out. Remove it from the heat as soon as it flakes easily.

Use Fresh Fish

Fresh mackerel offers the best flavor, texture, and aroma.

Serve Immediately

Grilled mackerel is at its best when served hot, with crisp skin and juicy flesh.

Delicious Variations

Miso-Grilled Mackerel

Marinate the fillets in a mixture of white miso, mirin, and sake before grilling for a sweet and savory twist.

Teriyaki Mackerel

Brush the fish with a homemade teriyaki sauce during the final minutes of grilling for a glossy glaze.

Spicy Grilled Mackerel

Season with:

  • Shichimi togarashi
  • Chili flakes
  • Black pepper

for extra heat.

Citrus Mackerel

Finish with freshly grated yuzu zest or a squeeze of sudachi juice for a bright, aromatic flavor.

Charcoal-Grilled Saba

Cook the fish over charcoal for a smoky aroma that complements the rich flesh.

What to Serve with Grilled Mackerel
