Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Prepare Compound Butter
In a medium bowl, combine the softened unsalted butter, white miso paste, brown sugar, grated ginger, minced garlic, and sliced green onions. Mix this delightful compound until all ingredients are well incorporated, creating a smooth and creamy texture. You can utilize a fork or a spatula for easier blending, and make sure it’s thoroughly mixed so every bite of your Miso Butter Salmon is flavorful.
Step 2: Top Salmon
Next, take your salmon fillets and place them skin-side down on a lined baking sheet or in a baking dish. Evenly distribute the miso butter mixture over each salmon fillet, ensuring to cover the fish completely for an irresistible glaze. This generous layer not only adds flavor but will also create a beautiful caramelized crust while cooking.
Step 3: Oven Method
Preheat your oven to 375°F (190°C) while you prepare your salmon. Place the baking dish with your topped salmon fillets in the oven and bake for 12-15 minutes. You’ll know it’s done when the salmon turns opaque and flakes easily with a fork. For an added touch, switch your oven to broil for an additional 1-2 minutes to achieve a perfectly caramelized top.
Step 4: Air Fryer Method
If you prefer using an air fryer, start by preheating it to 400°F (200°C). Once heated, line the air fryer basket with parchment paper and place the salmon fillets inside—without any need to flip them. Cook for about 9-10 minutes, keeping an eye on them until they are flaky and cooked through while maintaining that rich miso flavor.
Step 5: Serve
After cooking, remove the Miso Butter Salmon from the oven or air fryer and transfer it to a serving platter. Drizzle any remaining melted miso butter over the top and garnish with extra green onions or sesame seeds for a pop of color. Pair your salmon with steamed rice and vegetables to create a wholesome and stylish meal that’s both comforting and gourmet!

Miso Butter Salmon Recipe FAQs
What type of salmon should I use for the best results?
I recommend using wild-caught salmon fillets for the best flavor and texture. The richness of wild-caught salmon pairs perfectly with the miso butter, enhancing the overall dish.
How should I store leftover Miso Butter Salmon?
Store leftover Miso Butter Salmon in an airtight container in the refrigerator for up to 3 days. Make sure to cover it well to avoid drying out. When you’re ready to enjoy it again, gently reheat in the oven at 300°F (150°C) for about 10-15 minutes.
Can I freeze Miso Butter Salmon?
Absolutely! To freeze, place the cooled salmon in a tightly sealed freezer bag or container. It’s best to do this as soon as it’s cooked. Miso Butter Salmon can be kept in the freezer for up to 2 months. When you’re ready to enjoy, thaw in the fridge overnight and reheat gently.
What to do if my salmon is overcooked?
If your salmon has turned out dry, don’t worry! Try serving it with a drizzle of fresh sauce or butter to add moisture. You can also flake it into a salad or into rice, where added ingredients will help balance the dryness.
Is Miso safe for pets or those with allergies?
Miso contains soy, which may trigger allergies in some individuals, and it is not recommended for pets. If you have a soy allergy, you can experiment with tahini (sesame seed paste) as an alternative to miso, though it will have a different flavor profile.
How can I tell when my salmon is perfectly cooked?
To check for perfect doneness, look for an opaque color and flakiness. If you insert a fork gently, it should flake easily but still have a moist appearance inside. Using a food thermometer is even better – aiming for 145°F (63°C) ensures your Miso Butter Salmon is safe and delicious!
