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.
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.
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.
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.
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.
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.
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.
