Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Prepare the Miso Butter
In a mixing bowl, combine softened unsalted butter, white miso paste, brown sugar, grated fresh ginger, and minced garlic. Use a spatula to mix these ingredients until they are thoroughly integrated and creamy, about 2-3 minutes of vigorous mixing. This rich miso butter will be the star of your Miso Butter Salmon dish, so make sure it’s well-blended!
Step 2: Spread the Butter on Salmon
Take your salmon fillets and place them skin-side down on a baking dish or a lined air fryer basket. Using a knife or spatula, generously spread the miso butter mixture over the top of each fillet, ensuring even coverage from edge to edge. This creates a flavorful crust that will caramelize beautifully while cooking.
Step 3: Oven Cooking
Preheat your oven to 375°F (190°C). Once the oven is ready, place the salmon in a skillet or a baking dish and bake for 12-15 minutes. The salmon should turn opaque and flake easily with a fork; if desired, broil on high for 1-2 minutes to achieve a golden caramelized top, enhancing the flavors of your Miso Butter Salmon.
Step 4: Air Fry Cooking
For the air fryer method, preheat the air fryer to 400°F (200°C). Line the air fryer basket with parchment paper to prevent sticking, then place the salmon fillets inside. Cook for 9-10 minutes without flipping, allowing the hot air to create a crispy texture while keeping the fish tender and juicy. Your Miso Butter Salmon will be perfectly cooked and ready to serve!
Step 5: Serve and Garnish
Once cooked, carefully transfer the salmon onto a serving platter. Drizzle any remaining miso butter over the top for an extra boost of flavor. To finish, garnish with freshly sliced green onions and sesame seeds, if desired. Serve your Miso Butter Salmon alongside steamed rice and vegetables for a complete and delightful meal!

Miso Butter Salmon Recipe FAQs
What type of salmon should I use for Miso Butter Salmon?
Absolutely! For the best flavor and texture, I highly recommend using wild-caught salmon. Skin-on fillets help maintain moisture while cooking, resulting in a tender, flaky dish.
How long can I store leftover Miso Butter Salmon?
Leftover Miso Butter Salmon can be stored in an airtight container in the fridge for up to 3 days. Make sure to keep it well-sealed to prevent any unwanted odors from mingling with other foods in your refrigerator.
Can I freeze Miso Butter Salmon, and if so, how?

What can I do if the miso butter is too salty?
If you find the miso butter too salty, it’s happening mostly from the type of miso you chose. I recommend using a milder, white miso paste. If you’ve already mixed it, you can balance the saltiness by adding more unsalted butter and a little sugar to the mix. This will create a smoother, less salty flavor profile.

Very! If you choose a gluten-free miso paste, this dish is perfect for those avoiding gluten. Always check the labels on your miso paste and other ingredients for any hidden gluten sources to keep your meal safe.
How should I reheat leftover Miso Butter Salmon to keep it moist?
To maintain the delicious, flaky texture when reheating, preheat your oven to 300°F (150°C) and place the salmon on a baking sheet. Cover it with foil to lock in moisture and heat for about 15 minutes, or until warmed through. This gentle method helps it stay tender and avoids drying out.
