Instructions

  1. Step 1: Preheat oven to 425°F. Place 2 large sweet potatoes, peeled and cut into 1/2-inch thick slices, on a baking sheet, drizzle with 1 tbsp olive oil, and season with salt and pepper. Toss to coat and spread in a single layer. Roast for 20 minutes until tender and golden at the edges.
  2. Step 2: In a small bowl, whisk together 2 tbsp white miso paste, 1 tbsp rice vinegar, 1 tbsp honey, and 1 tbsp sesame oil until smooth. Pat 4 salmon fillets (6 oz each) dry with paper towels and season lightly with salt and pepper. Brush each fillet evenly with the miso glaze.
  3. Step 3: Place the salmon fillets on the baking sheet with the sweet potatoes, then add 1 lb asparagus, woody ends snapped off, around the edges. Brush asparagus with a little olive oil and season with salt and pepper.
  4. Step 4: Roast for 12-15 minutes until the salmon is cooked through (internal temperature 145°F) and the asparagus is tender-crisp, with the glaze bubbling and slightly caramelized.
  5. Step 5: Remove from oven and let rest for 5 minutes. Serve immediately with the roasted vegetables.

How do I store leftover Miso-Glazed Salmon with Roasted Sweet Potatoes and Asparagus?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).

How do I scale Miso-Glazed Salmon with Roasted Sweet Potatoes and Asparagus for a different number of people?
