Instructions

  1. Step 1: Preheat oven to 400°F. Whisk 3 tablespoons white miso paste, 2 tablespoons mirin, 1 tablespoon rice vinegar, and 1 teaspoon honey in a small bowl. Place salmon skin-side down on parchment-lined baking sheet. Brush miso glaze evenly over salmon.
  2. Step 2: Bring a pot of salted water to boil. Add 4 cut sweet potatoes and cook until fork-tender, about 15 minutes. Drain, return to pot, and add 2 tablespoons unsalted butter, 1 teaspoon wasabi powder, and salt to taste. Mash until smooth.
  3. Step 3: Bake salmon for 12–15 minutes until glaze bubbles and salmon is opaque in center. Serve with wasabi mashed sweet potatoes, drizzling any pan juices over salmon.
