Miso Butter Salmon Ingredients
For the Salmon
• Salmon fillets (6 oz each) – Main protein source. Opt for wild-caught varieties for better flavor and quality.
For the Miso Butter
• Unsalted butter (6 tbsp, softened) – Adds fat and richness. Use salted butter with caution, as it alters the salt level.
• White miso paste (3 tbsp) – Introduces umami flavor. Regular miso can be used; adjust quantity for saltiness.
• Brown sugar (1 tbsp) – Balances the savory elements with sweetness. Can substitute with honey or maple syrup for different flavor profiles.
• Fresh ginger (2 tsp, grated) – Adds warmth and spice. Use powdered ginger as a substitute in lesser amounts.
• Garlic (1-2 cloves, minced) – Contributes aromatic depth. Ensure it’s finely minced for even distribution.
• Green onions (2 tbsp, sliced thin) – Provides freshness and color. Chives can be a substitute for a similar taste.
Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Prepare the Compound Butter
In a medium bowl, combine 6 tablespoons of softened unsalted butter, 3 tablespoons of white miso paste, 1 tablespoon of brown sugar, 2 teaspoons of grated fresh ginger, 1-2 minced garlic cloves, and 2 tablespoons of sliced green onions. Using a fork, mash and mix everything until smooth and well combined, resulting in a flavorful miso butter that will elevate your salmon.
Step 2: Top the Salmon
Take your fresh salmon fillets and place them skin-side down on a lined baking sheet. With a spatula or the back of a spoon, evenly spread the prepared miso butter over the top of each fillet, ensuring all surfaces are covered. This will create a delicious glaze as the salmon cooks, infusing it with rich, umami flavors.
Step 3: Cook in the Oven
Preheat your oven to 375°F (190°C). Once it’s hot, place the baking sheet with the salmon in the oven and bake for 12 to 15 minutes. You’ll know your Miso Butter Salmon is done when it appears opaque and flakes easily with a fork. For an extra touch, broil the salmon on high for 1-2 minutes to caramelize the tops slightly.
Step 4: Cook in the Air Fryer
If you prefer a quicker method, preheat your air fryer to 400°F (200°C). Line the air fryer basket with parchment paper to prevent sticking. Carefully place the salmon fillets inside the basket, ensuring they’re not touching. Cook for about 9 to 10 minutes without flipping, checking for doneness; it should be opaque and flaky as well.
Step 5: Serve
Once your Miso Butter Salmon is perfectly cooked, transfer the fillets to a serving platter. Drizzle any remaining miso butter from the baking sheet over the salmon, and garnish with additional sliced green onions and sesame seeds for extra flavor and visual appeal. Pair this delightful dish with steamed rice and vegetables for a satisfying meal.
