Miso-Glazed Trumpet Mushroom “Scallops”
Miranda | The Herby Eater
These miso-glazed trumpet mushroom “scallops” are a flavorful, plant-based twist on a seafood classic. Marinated in white miso, soy sauce, nori, and maple syrup, then pan-seared and served over creamy edamame purée—they’re fancy enough for date night but simple enough for a weeknight.

For the Trumpet “Scallops”
- 3 large trumpet mushrooms aka king oyster, stems only
- 1 tablespoon white miso paste
- 1 tablespoon soy sauce or tamari
- 1 teaspoon maple syrup
- 1 sheet nori finely crumbled or torn
- ¼ cup hot vegetable stock or hot water
- Neutral oil for searing (e.g., avocado or grapeseed)
For the Edamame Purée
- 1½ cups shelled edamame thawed if frozen
- 1 clove garlic minced
- Juice of ½ lemon
- 1 –2 tablespoons olive oil
- Salt to taste
- Water or additional olive oil as needed to blend
For Garnish
- Fresh parsley or microgreens
- Extra drizzle of the miso marinade reduced (optional)
Wipe the trumpet mushrooms clean. Slice the stems into 1-inch thick rounds.
On one flat side of each round, score a shallow “X” about ¼ inch deep—this helps the marinade soak in and gives a scallop-like texture.
In a shallow bowl, whisk together white miso, soy sauce, maple syrup, nori, and hot vegetable stock. The heat from the stock helps dissolve the miso and activates the umami.
Place the mushrooms cut-side down into the marinade. Let them soak for 30 minutes, flipping once halfway through if needed.
While the mushrooms marinate, steam or simmer the edamame until tender (about 5 minutes).
Transfer to a blender or food processor with garlic, lemon juice, olive oil, and a pinch of salt. Blend until smooth, adding a splash of water or more oil if needed for consistency.
Taste and adjust seasoning. Set aside.
Heat a pan over medium-high heat with a little oil.
Remove mushrooms from the marinade (reserve it if you’d like to reduce and drizzle later).
Sear mushrooms, scored side down first, for about 2–3 minutes per side until golden and caramelized.
Spread a generous swipe of edamame purée on each plate.
Top with 3–4 mushroom "scallops" per plate.
Garnish with parsley or microgreens, and optionally drizzle with reduced marinade.
Nori tip: If you don’t have sheets, you can use furikake seasoning or a sprinkle of seaweed flakes.
Leftovers: Store mushrooms and purée separately in airtight containers in the fridge.
Reheat mushrooms in a hot pan to maintain texture.
