Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Make Miso Butter
In a medium bowl, combine softened unsalted butter, white miso paste, brown sugar, freshly grated ginger, minced garlic, and thinly sliced green onions. Mix together using a fork or spatula until everything is well incorporated and creamy. This rich miso butter will provide a delicious glaze for your Miso Butter Salmon, so ensure it is thoroughly combined before moving on to the next step.
Step 2: Prepare Salmon
Preheat your oven to 375°F or your air fryer to 400°F, while you prepare the salmon fillets. Pat the salmon dry with paper towels for better searing, then place them skin-side down on a baking sheet or air fryer basket lined with parchment paper. Generously spread the prepared miso butter over each fillet, ensuring an even coating that covers the surface for maximum flavor.
Step 3: Cook (Oven Method)
For the oven method, place the baking dish with the prepared Miso Butter Salmon in the preheated oven. Bake for 12-15 minutes until the salmon is opaque and flakes easily with a fork. To achieve a beautifully caramelized top, switch to broil for an additional 1-2 minutes at the end, keeping a close eye to prevent burning.
Step 4: Cook (Air Fryer Method)
If using the air fryer, place the coated salmon fillets in the basket skin-side down, making sure they don’t overlap. Cook for 9-10 minutes until the salmon is cooked through and flakes easily. The air fryer creates a satisfying crispy texture on the edges, making your Miso Butter Salmon absolutely divine.
Step 5: Serve
Once either cooking method is complete, carefully remove the Miso Butter Salmon from the oven or air fryer and transfer to a serving platter. Drizzle some extra miso butter over the top for added richness, and garnish with additional sliced green onions. This lovely dish pairs beautifully with steamed rice and seasonal vegetables for a complete meal.

Expert Tips for Miso Butter Salmon
• Room Temperature: Let salmon sit out for 15 minutes before cooking; this ensures even cooking throughout each fillet.
• Broiling Caution: Keep a close watch while broiling the salmon to avoid any burning; that caramelized topping should be golden, not charred!
• Prep Ahead: Make your miso butter in advance and store it in the refrigerator for up to 5 days; it softens quickly at room temperature or in the microwave.
• Cooking Time: Since salmon thickness varies, check for doneness a minute early; perfectly cooked Miso Butter Salmon should flake easily and be opaque throughout.
• Optional Heat: For an added kick, mix in 1 teaspoon of sriracha into the miso butter; this elevates your dish to a whole new savory level!

Miso Butter Salmon Recipe FAQs
How do I choose the right salmon fillets?
Absolutely! When selecting salmon fillets, look for high-quality, wild-caught options for the best flavor. The skin-on variety is ideal because it helps retain moisture during cooking. Fresh fillets should have a vibrant color without any dark spots or an overly fishy smell.
How should I store leftover Miso Butter Salmon?
Very good question! Store any leftover Miso Butter Salmon in an airtight container in the refrigerator for up to 3 days. This keeps the salmon flavorful and moist. Reheat it gently at 300°F to ensure it remains tender and doesn’t dry out—just enough time to restore its luscious texture!
Can I freeze Miso Butter Salmon?
Of course! If you’d like to freeze your Miso Butter Salmon, wrap the cooked fillets tightly in plastic wrap or place them in a heavy-duty freezer bag. They can be stored in the freezer for up to 2 months. When you’re ready to enjoy, thaw overnight in the refrigerator, and for the best results, reheat at 300°F to avoid drying it out.
What if my salmon is cooking unevenly?
Sometimes this can happen, but it’s easily fixable! Ensure that your salmon is at room temperature before cooking—let it sit out for about 15 minutes. Also, check your oven or air fryer temperature; they should be preheated correctly to 375°F or 400°F, respectively. If one end cooks faster, you might want to rotate the pan halfway through for even cooking.
Is Miso Butter Salmon suitable for special diets?
Very much so! As noted, you can make it gluten-free by using gluten-free miso paste. If someone has a seafood allergy, consider using chicken or tofu instead, adjusting the cooking times accordingly to ensure they’re fully cooked. Additionally, it’s a healthy dish packed with omega-3 fatty acids, making it a great choice for health-conscious eaters.
How do I enhance the flavors of Miso Butter Salmon?
Oh, the more the merrier! For an extra flavor boost, consider adding a teaspoon of sriracha to your miso butter mixture for a spicy kick or sprinkle sesame seeds on top before serving.
