Instructions

  1. Step 1

    Make the miso butter: In a small bowl, whisk together the white miso paste, softened butter, sake, mirin, and lemon juice until smooth and fully combined. Set aside at room temperature.

  2. Step 2

    Prepare the fish: Pat the white fish fillets dry with paper towels, then brush both sides lightly with olive oil. Season generously with kosher salt and black pepper on both sides, about 2 minutes before grilling.

  3. Step 3

    Heat your grill to medium-high heat (about 400°F). Oil the grates well using a folded paper towel dipped in oil to prevent sticking.

  4. Step 4

    Grill the fish: Place the fillets on the grill, skin-side up if skin is attached, and cook for 4-5 minutes without moving them. You should see light char marks forming on the bottom.

  5. Step 5

    Flip the fillets carefully using a thin spatula and grill the other side for 3-4 minutes until the fish is opaque throughout and flakes easily when gently pressed with a fork. Internal temperature should reach 145°F.

  6. Step 6

    Transfer the grilled fish to a warm serving plate. Top each fillet generously with a spoonful of the miso butter, which will begin to melt into the warm fish.

  7. Step 7

    Garnish immediately with sliced scallions and sesame seeds, then serve warm. The residual heat will help the miso butter coat the fish beautifully.
