Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Make the 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 1-2 minced garlic cloves. Mix vigorously with a spatula until the ingredients are well blended and creamy, creating a flavorful miso butter. Set this aside while you prepare the salmon.
Step 2: Prep the Salmon
Place your 6 oz salmon fillets on a baking sheet lined with parchment paper. Using a spatula, spread the prepared miso butter evenly over the top of each fillet, ensuring they are generously covered. This layer will not only enhance flavor but will also help create a deliciously caramelized crust as they cook.
Step 3: Cook (Oven Method)
Preheat your oven to 375°F (190°C). Once heated, place the baking sheet with the salmon in the oven and bake for about 12-15 minutes. The salmon should become opaque and flake easily with a fork. For a finishing touch, switch your oven to broil for an additional 1-2 minutes to caramelize the top of the miso butter beautifully.
Step 4: Cook (Air Fryer Method)
If you choose the air fryer option, preheat it to 400°F (200°C). Line the basket with parchment or foil to prevent sticking, then carefully arrange the prepared salmon fillets inside. Cook for 9-10 minutes without flipping. The air fryer will give the salmon a nice, crispy exterior while ensuring the inside remains tender and juicy.
Step 5: Serve
Once cooked, transfer the Miso Butter Salmon to a serving platter. Drizzle any remaining miso butter over the fillets for an extra burst of flavor. Garnish with the thinly sliced green onions for a fresh finish. For a complete meal, consider serving it alongside steamed rice and colorful vegetables to complement this savory dish.

How to Store and Freeze Miso Butter Salmon
Fridge: Store leftover Miso Butter Salmon in an airtight container for up to 3 days. Make sure to cover the salmon with a little extra miso butter to keep it moist.
Freezer: Wrap individual fillets tightly in plastic wrap, then place them in a freezer bag. They can be frozen for up to 2 months; remember to label the bags for easy identification.
Reheating: To reheat, thaw the salmon overnight in the fridge. Reheat in a preheated oven at 300°F (150°C) for about 15 minutes to maintain moisture and tenderness.
Enjoying Leftovers: Use any remaining miso butter to enhance other meals or drizzle over steamed vegetables for added flavor!
Make Ahead Options
These Miso Butter Salmon fillets are perfect for meal prep enthusiasts! You can prepare the miso compound butter up to 3 days in advance; simply mix together the softened butter, miso paste, brown sugar, grated ginger, minced garlic, and sliced green onions, then store it in an airtight container in the refrigerator. When you’re ready to cook, spread the miso butter on the salmon fillets, which you can also season in advance and refrigerate for up to 24 hours. Just remember to let the salmon reach room temperature before baking or air frying to ensure even cooking. Follow the cooking instructions, and you’ll enjoy a stunning dinner that’s just as delicious as if it were freshly made!

Miso Butter Salmon Recipe FAQs
What type of salmon should I use for this recipe?
Absolutely! For the best flavor and texture, I recommend using wild-caught salmon fillets of about 6 oz each. This will ensure a rich taste and flaky, moist interior. Farmed salmon can also work but may have a different flavor profile.
How should I store leftover Miso Butter Salmon?
Store your leftover Miso Butter Salmon in an airtight container in the fridge for up to 3 days. To keep it moist, cover the salmon with a little extra miso butter before sealing. Just remember to let it cool completely before refrigeration!
Can I freeze Miso Butter Salmon?
Yes, you can! For freezing, wrap each individual fillet tightly in plastic wrap, then place them in a freezer bag. Make sure to label the bags. They can stay in the freezer for up to 2 months. When you’re ready to enjoy them, simply thaw in the refrigerator overnight before reheating.
What should I do if the salmon is dry after cooking?
If you find your salmon is a bit dry, it might be due to overcooking. To prevent this, use a meat thermometer; salmon is perfectly cooked when it reaches an internal temperature of 145°F (63°C). Also, make sure to let it rest for a few minutes after cooking so the juices redistribute for a tender bite.
Is Miso Butter Salmon suitable for dietary restrictions?
If you have dietary restrictions, you can make some adjustments! For a dairy-free option, substitute the unsalted butter with olive oil or dairy-free margarine, but keep in mind, it may alter the flavor slightly. Always check for any allergies related to fish and miso paste, especially if dining with others who may have specific food sensitivities.
How long can I keep miso paste in the fridge?
Unopened miso paste can last in the refrigerator for up to a year, while opened miso should be used within 3 months for the best flavor. Make sure to store it in an airtight container to keep it fresh!
