This miso butter foil-baked salmon is a simple Japanese-inspired seafood dinner with rich umami flavor and plenty of tender vegetables. The salmon is lightly marinated, wrapped in foil, and gently steam-baked until juicy, making it an easy meal that feels both comforting and elegant.
In a small bowl, stir together the miso, soy sauce, and sake until smooth. Divide the mixture into 5 equal portions. Check the salmon fillets and remove any pin bones.

Rub 1 portion of the miso mixture over each salmon fillet, using 4 portions total. Wrap or cover the fillets tightly and refrigerate for at least 1 hour, or up to half a day, to let the flavor absorb.

About 10 minutes before cooking, let the butter soften at room temperature. Mix the remaining 1 portion of miso sauce with the softened butter until evenly combined.

Rinse the bean sprouts and trim the roots if desired. Cut the carrot into thin matchsticks and separate the shimeji mushrooms into small clusters.

Cut 4 large sheets of foil. Lightly grease the center of each sheet with a little butter. Gently scrape off any excess marinade from the salmon, then place 1 fillet skin-side down on each sheet.

Divide the bean sprouts, carrot, and shimeji mushrooms evenly over the 4 salmon fillets. Spoon the miso butter mixture evenly over the vegetables.

Fold and seal each foil packet well so the steam stays inside while cooking.

Place the foil packets in a large skillet or sauté pan and cover with a lid. Cook over medium heat for about 10 minutes, or until the salmon is just cooked through and the vegetables are tender. Serve immediately.

If you do not have sake, use a small splash of water or dry white wine. Avoid overcooking the salmon, since it will continue to steam briefly after you remove it from the pan. Leftovers can be refrigerated in an airtight container for up to 2 days.
