Miso Butter Salmon Ingredients
• Get ready to savor the goodness!
For the Salmon
- Salmon fillets (6 oz each) – Choose wild-caught for the best flavor and texture; skin-on helps lock in moisture.
For the Miso Butter
- Unsalted butter (6 tbsp, softened) – This rich base provides creaminess and depth to the overall dish.
- White miso paste (3 tbsp) – Delivers a savory umami flavor; other miso types can be used but adjust for saltiness.
- Brown sugar (1 tbsp) – Adds a touch of sweetness that beautifully balances the miso; honey works in a pinch for a different twist.
- Fresh ginger (2 tsp, grated) – Brings warmth and zest; fresh is preferable, but powdered ginger will do if needed.

- Green onions (2 tbsp, sliced thin) – Offers a refreshing crunch and a pop of color; any mild onion makes a good substitute.
You’re on your way to crafting a delightful Miso Butter Salmon meal!
Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Prepare 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 to 2 cloves of minced garlic. Mix these ingredients together until they form a smooth and cohesive compound butter. As you combine them, let the aroma of miso and ginger fill your kitchen, setting the stage for your flavorful Miso Butter Salmon.
Step 2: Top Salmon
Take your salmon fillets (6 oz each) and place them on a clean surface or baking sheet. Using a butter knife or spatula, evenly spread the prepared miso butter over the top of each salmon fillet, ensuring they are well coated. This step is crucial as it ensures every bite of your Miso Butter Salmon is infused with that delicious umami flavor from the butter.
Step 3: Cook (Oven Method)
Preheat your oven to 375°F (190°C). Once heated, place the salmon fillets in a baking dish, ensuring they’re spaced apart for even cooking. Bake for 12 to 15 minutes, or until the salmon is opaque and flakes easily with a fork. For a beautiful caramelized top, switch the oven to broil and cook for an additional 1 to 2 minutes, keeping a close eye to prevent burning.
Step 4: Cook (Air Fryer Method)
If you prefer the air fryer, preheat it to 400°F (200°C). Line the air fryer basket with parchment paper to prevent sticking and enhance cleanup. Carefully place the coated salmon fillets into the basket, ensuring they don’t touch. Cook for 9 to 10 minutes without flipping until the salmon is tender and the surface is slightly crispy. This method results in a juicy Miso Butter Salmon with a quickly cooked top.
Step 5: Serve
Once cooked, transfer the salmon fillets to a serving platter. For an extra burst of flavor, drizzle any remaining miso butter over the top. Garnish with thinly sliced green onions and, if you like, sprinkle some sesame seeds for added crunch. Serve this delightful Miso Butter Salmon alongside steamed rice or sautéed vegetables for a complete meal that tantalizes your taste buds.
