Step‑by‑Step Instructions for Miso Butter Salmon
Step 1: Prepare Miso Butter
In a medium bowl, combine 6 tablespoons of softened unsalted butter with 3 tablespoons of white miso paste, 1 tablespoon of brown sugar, 2 teaspoons of grated fresh ginger, and 1-2 cloves of minced garlic. Mix everything together using a fork or spatula until the ingredients are well blended. You want a smooth, creamy consistency that’s packed with flavor, ideal for coating the salmon.
Step 2: Apply Miso Butter
Using a butter knife or spatula, evenly spread the prepared miso butter mixture over each salmon fillet, allowing it to coat the fish thoroughly. Ensure the butter mixture reaches all corners of the fillet to maximize flavor. You should see a thick, glossy layer on top, ready to create that delightful crust while cooking.
Step 3: Cook Salmon in Oven
Preheat your oven to 375°F (190°C). Place the coated salmon fillets on a baking sheet lined with parchment paper. Bake the salmon for 12-15 minutes, or until the fish is opaque and flakes easily with a fork. For an extra touch, switch to broil for an additional 1-2 minutes to achieve a beautifully caramelized topping on the Miso Butter Salmon.
Step 4: Cook Salmon in Air Fryer
Preheat your air fryer to 400°F (200°C). Carefully arrange the salmon fillets in the air fryer basket, ensuring they are not overcrowded. Cook for about 9-10 minutes without flipping, until the salmon is flaky and has a delightful crust. The air fryer gives a wonderfully crispy texture without any added oil, enhancing the rich flavors of the miso butter.
Step 5: Serve
Once cooked, transfer the delicious Miso Butter Salmon to a serving platter. Drizzle any remaining miso butter over the top and garnish with thinly sliced green onions and a sprinkle of sesame seeds for added flavor and crunch. Pair with steamed rice or vegetables to complete your meal, allowing the rich umami to shine through with every bite.

How to Store and Freeze Miso Butter Salmon
Fridge: Store cooked Miso Butter Salmon in an airtight container for up to 3 days. Ensure it cools to room temperature before sealing to minimize moisture buildup.
Freezer: For longer storage, freeze cooked salmon up to 2 months. Wrap each fillet tightly in plastic wrap, followed by aluminum foil, to prevent freezer burn.
Reheating: To reheat, place the salmon in a preheated oven at 300°F (150°C) for 10-15 minutes until heated through. This helps retain moisture and flavor.
Leftover Miso Butter: Any leftover miso butter can be refrigerated in a separate container for up to 5 days. Allow it to soften before spreading over dishes.

Expert Tips for Miso Butter Salmon
-
Fresh Ingredients: Use freshly grated ginger and minced garlic for the best flavor; dried or powdered versions won’t provide the same aromatic depth.
-
Even Cooking: Let the salmon sit at room temperature for about 15 minutes before cooking. This ensures even cooking and prevents the center from being too cold.
-
Broiling Caution: Keep a close eye while broiling. The goal is a lightly caramelized top, but it can quickly turn from perfectly golden to burnt.
-
Cooking Time Accuracy: Every oven and air fryer differs slightly, so keep an eye on the cooking process. Salmon should be flaky and opaque but not dry.
-
Miso Paste Storage: Miso can be found in the refrigerated section; seal and store it properly to keep it fresh for future recipes, ensuring you always have it on hand for your Miso Butter Salmon.

Miso Butter Salmon Recipe FAQs
How do I select the best salmon for this recipe?
When choosing salmon, opt for wild-caught if possible, as it tends to be fresher and has more flavor. Look for vibrant, moist fillets with a bright color and minimal dark spots or browning. If you notice any dark spots all over the fish, it indicates that it may not be fresh.
What’s the best way to store leftover Miso Butter Salmon?
You can store any cooked Miso Butter Salmon in an airtight container in the fridge for up to 3 days. Ensure the salmon cools to room temperature before sealing to prevent excess moisture buildup, which can make the fish soggy.
Can I freeze Miso Butter Salmon? What’s the process?
Absolutely! You can freeze the cooked salmon for up to 2 months. To freeze, wrap each fillet tightly in plastic wrap and then in aluminum foil to protect against freezer burn. When ready to eat, thaw overnight in the fridge and reheat gently in a preheated oven at 300°F (150°C) for 10-15 minutes.
What should I do if my salmon is overcooked?
If your salmon turns out overcooked, don’t fret! The best way to salvage it is to make a quick sauce or topping, like a yogurt dressing or an herb pesto, to drizzle over the salmon; this can reintroduce moisture and flavor. Another trick is to flake the salmon into a salad to repurpose it and enjoy it in another dish.
Are there any dietary considerations for this recipe?
Yes! If you have a soy allergy, you should avoid using miso altogether, as it is fermented soy. A great alternative would be to create a similar flavor profile using tahini or a combination of sunflower seed butter mixed with some umami-rich additions, like nutritional yeast. Always check the specific ingredients to accommodate any other dietary restrictions you might have.
What if I don’t have miso paste?
In a pinch, you can substitute miso paste with tahini or almond butter mixed with a splash of soy sauce or tamari for that savory flavor. Just remember to adjust seasonings accordingly, as these will have different salt levels compared to miso. It’s a great way to keep that umami flavor alive even without the traditional ingredient!
