Instructions

1. Step 1: Preheat oven to 400°F (200°C). In a small bowl, whisk together 2 tbsp miso paste, 2 tbsp soy sauce, 1 tbsp mirin, and 1 tbsp honey. Set aside.
2. Step 2: Place salmon fillets on a baking sheet lined with parchment paper. Brush the miso glaze generously over the top and sides of each fillet. Bake for 12-15 minutes until the glaze is caramelized and the salmon is flaky and cooked through.
3. Step 3: While the salmon bakes, peel and cube 2 large sweet potatoes. In a large pot, boil the sweet potatoes with 1/2 tsp salt until tender, about 15-20 minutes. Drain and mash with 4 tbsp butter, 2 minced garlic cloves, 1/4 tsp black pepper, and additional salt to taste.
4. Step 4: Serve the salmon with the mashed sweet potatoes, garnished with a drizzle of glaze and a sprinkle of sesame seeds if desired.
