Miso Butter Salmon Ingredients
For the Salmon
• Salmon fillets (6 oz each) – This is your main protein source, adding rich flavor and texture; using skin-on ensures moisture retention.
For the Miso Butter
• Unsalted butter (6 tablespoons, softened) – It adds richness and helps create the compound butter; vegan butter can be used for a dairy-free option.
• White miso paste (3 tablespoons) – Contributes an umami and sweet flavor to the dish; if using regular miso, reduce the amount slightly to avoid excessive saltiness.
• Brown sugar (1 tablespoon) – Enhances sweetness and aids in caramelization; substitute with coconut sugar for a healthier choice.
• Fresh ginger (2 teaspoons, grated) – Introduces warmth and spice; fresh ginger is preferred for its flavor compared to ground ginger.
• Garlic (1-2 cloves, minced) – Provides aromatic complexity; fresh garlic is always best, but garlic powder can be a substitute in a pinch.
• Green onions (2 tablespoons, sliced thin) – Adds freshness and a mild onion flavor; feel free to use chives if desired.

Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Prepare Miso 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 thinly sliced green onions. Mash all the ingredients together using a fork or spatula until well blended and creamy, ensuring the flavors meld together beautifully.
Step 2: Top Salmon
Take your salmon fillets and place them skin-side down on a lined baking sheet or in an oven-safe skillet. Evenly spread the prepared miso butter mixture over each salmon fillet using a butter knife or spatula, ensuring each piece is generously coated to achieve that sweet and savory goodness in every bite.
Step 3: Cooking Method – Oven
Preheat your oven to 375°F (190°C). Once heated, place the baking sheet or skillet in the oven and bake the salmon for 12-15 minutes, or until the fish is opaque and flakes easily with a fork. For an additional touch, switch the oven to broil mode and broil the salmon on high for 1-2 minutes to develop a beautifully caramelized top—keep a close eye to avoid burning.
Step 4: Cooking Method – Air Fryer
If using an air fryer, preheat it to 400°F (200°C). Line the air fryer basket with parchment paper to prevent sticking, then carefully place the salmon fillets inside. Cook for 9-10 minutes without flipping, until the salmon is cooked through and has developed a slightly crisp exterior, perfectly embodying the essence of miso butter salmon.
Step 5: Serve
Once cooked, carefully transfer the salmon fillets to a serving platter. Drizzle any remaining miso butter on top and garnish with additional green onions and sesame seeds for a burst of flavor and visual appeal. Serve your miso butter salmon with steamed jasmine rice or sautéed vegetables to complete this delightful dish.

Miso Butter Salmon Recipe FAQs
How do I choose ripe salmon fillets?
When selecting salmon, look for vibrant color and a fresh ocean smell. The flesh should be firm to the touch, not mushy, and avoid any fillets with dark spots or a dull appearance. If possible, opt for skin-on fillets, as they retain moisture better during cooking.
How do I store leftover miso butter salmon?
You can refrigerate leftover miso butter salmon in an airtight container for up to 3 days. Allow the salmon to cool completely before sealing it to maintain moisture and flavor.
Can I freeze miso butter salmon?
Absolutely! To freeze, wrap the cooled salmon tightly in plastic wrap, then in aluminum foil, making sure it’s well-sealed. You can keep it in the freezer for up to 2 months. When you’re ready to enjoy it, simply thaw in the refrigerator overnight and reheat gently.
What should I do if my salmon is dry after cooking?
If your salmon turns out dry, it could be due to overcooking. Always keep an eye on the salmon as it cooks, relying on visual cues like the color change and flakiness. Adding a drizzle of extra miso butter or a splash of soy sauce can also help restore some moisture when serving.
Is miso paste safe for my pets?
While miso paste itself isn’t toxic to pets, it’s best to avoid giving it to them due to its high sodium content. Always check with your veterinarian before introducing new foods into your pet’s diet, and keep this delicious miso butter salmon just for your own enjoyment!
What can I substitute for miso paste in this recipe?
If you need to substitute miso paste, using tahini can work in a pinch, but you may want to add a bit more sugar for sweetness. Alternatively, blending equal parts soy sauce and almond butter can also create a similar savory profile without compromising your dish’s flavor too much.
