Miso Butter Salmon Ingredients
For the Salmon
• Salmon fillets (6 oz each) – The main protein providing healthful omega-3 fatty acids; wild-caught salmon offers the best flavor and texture.
For the Miso Butter
• Unsalted butter (6 tablespoons, softened) – Adds richness and creaminess essential for the compound butter; substitute with olive oil for a dairy-free version.
• White miso paste (3 tablespoons) – Infuses umami and subtle sweetness into the butter; regular miso can be used but reduce the amount to avoid too much saltiness.
• Brown sugar (1 tablespoon) – Enhances sweetness and aids in caramelizing the salmon during cooking.
• Fresh ginger (2 teaspoons, grated) – Adds a refreshing zest and aromatic quality to the dish.
• Garlic (1-2 cloves, minced) – Contributes depth with a slight sharpness in flavor.
• Green onions (2 tablespoons, sliced thin) – Fresh garnish adding a mild bite and brightness to the dish.
With these Miso Butter Salmon ingredients, you’re all set to create something truly special!
Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Make 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, and 1-2 cloves of minced garlic. Use a fork to mash everything together until well blended and creamy. This flavorful miso butter mixture will serve as a delightful topping for your salmon, enhancing its savory charm.
Step 2: Prepare the Salmon
Pat the salmon fillets dry with a paper towel to remove excess moisture, then let them sit at room temperature for about 15 minutes. This helps ensure even cooking. Meanwhile, preheat your oven to 375°F if you plan to bake, or your air fryer to 400°F if you’re going that route. The salmon will be ready for the delicious miso butter topping shortly!
Step 3: Top the Salmon Fillets
Evenly divide the prepared miso butter over each salmon fillet, ensuring they are generously coated. Use a spatula or the back of a spoon to spread the mixture on top, covering the surface completely. This will give your salmon a flavor-packed crust that caramelizes beautifully during cooking, bringing the essence of Miso Butter Salmon to life.
Step 4: Cook in the Oven
Place the salmon fillets in a lightly greased baking dish, ensuring they are spaced apart. Bake in the preheated oven for 12-15 minutes until the salmon is opaque and flakes easily with a fork. For an added touch, switch to broil for the last 1-2 minutes to achieve a beautifully caramelized surface, enhancing the deliciousness of your Miso Butter Salmon.
Step 5: Cook in the Air Fryer
If you prefer using the air fryer, line the basket with parchment for easy cleanup. Arrange the salmon fillets inside without flipping them. Cook at 400°F for 9-10 minutes, checking occasionally for doneness. The air fryer method will give you tender, perfectly cooked salmon with slightly crispy edges that beautifully showcase the miso butter.
Step 6: Serve the Miso Butter Salmon
Once cooked, carefully transfer the salmon to a platter, drizzling any remaining miso butter from the baking dish on top. Garnish with thinly sliced green onions and sesame seeds for a touch of freshness and color. Serve your delightful Miso Butter Salmon with steamed rice and vegetables for a wholesome meal that will impress everyone at your table!
