Looking for a fast, simple, and incredibly tasty way to elevate salmon night? Meet miso butter salmon: a savory glaze of miso and butter brushed over pan-seared salmon fillets, served with quick stir-fried vegetables and a bed of rice for a complete dinner in about 20 minutes.
We cook salmon regularly at home, so I’m always searching for new, delicious preparations. Miso can feel mysterious if you’ve never used it, but it’s an easy pantry staple that lends deep umami and pairs beautifully with salmon.
What is miso?
Miso is a paste made from fermented soybeans, often combined with rice or barley. It brings a rich, savory umami flavor common in Japanese cooking and helps thicken sauces and glazes. In this recipe, white miso is mixed with butter, brown sugar, mirin, soy sauce, and fresh garlic to create a glossy, flavorful glaze that complements the flaky salmon.

Ingredients
Miso butter salmon
- 4 tablespoons unsalted butter, softened
- 2 tablespoons white miso paste (white or red miso works)
- 3 cloves garlic, minced
- 2 teaspoons mirin
- 1 1/2 tablespoons brown sugar
- 2 tablespoons low-sodium soy sauce (or coconut aminos/tamari for gluten-free)
- Swish of avocado or other high-heat oil
- 3–4 salmon fillets (about 6 oz each)
- Pinch of fine sea salt and black pepper
The rest
- 8 oz sugar snap peas
- 8 oz shiitake mushrooms (or other mushrooms like cremini)
- 1 avocado, thinly sliced
- Green onions, chopped
- Furikake seasoning or sesame seeds
- Rice, quinoa, or grain of your choice (optional)
How to make miso butter salmon
1. Prep the veg: slice shiitake mushrooms and trim the ends of the snap peas.
2. Make the miso butter: mash together softened butter, miso, minced garlic, mirin, soy sauce, and brown sugar until combined. The mixture may look slightly separated at first—don’t worry; it comes together when heated.
3. Sear the salmon: pat fillets very dry and season with salt and pepper. Heat a tablespoon of high-heat oil in a large skillet over medium-high heat. Place fillets flesh-side down and cook for about 4 minutes to develop a good sear.
4. Flip and glaze: carefully flip fillets so the skin is down, add a heaping spoonful of miso butter to each fillet, cover the pan, and cook 4–6 more minutes depending on thickness. The salmon is done when opaque and flakey—internal temperature around 140–145°F (it will rise slightly after removing from heat).
5. Stir-fry the veg: remove the salmon and add mushrooms and snap peas to the hot pan. There should be enough fat and glaze left to cook them; use the vegetables’ moisture to loosen browned bits. Stir-fry over high heat until mushrooms caramelize and snap peas are crisp-tender. Toss with an extra spoonful of miso butter to coat.
6. Assemble: plate rice or grain, top with miso butter salmon, add stir-fried veggies, sliced avocado, chopped green onions, and a sprinkle of furikake or sesame seeds. Serve immediately.
Tips and variations
- If you have leftover miso butter, toss it with pasta, spread it on roasted vegetables, or use it as a sauce for chicken, pork, tofu, or more fish.
- To make this gluten-free, swap soy sauce for tamari or coconut aminos.
- Adjust cooking time based on fillet thickness; thinner fillets will finish faster.
- Swap mushrooms for other quick-cooking vegetables like bok choy, snap peas, or baby kale.
FAQs
Often yes—this recipe makes a generous amount of sauce. Extra miso butter stores well and is delicious repurposed.
Keep leftover miso butter in an airtight container in the fridge for up to 5 days. Store salmon and vegetables separately in airtight containers; add avocado just before serving.
Use an instant-read thermometer: 145°F is the USDA-recommended temperature, though many cooks pull salmon at 140–142°F to account for carryover cooking. The fish should be opaque and flake easily.
