Introduction
Experience the savory delight of Miso Soy King Oyster Mushrooms, a perfect vegan alternative to scallops. These tender, flavorful mushrooms are marinated in a rich miso soy blend and seared to caramelized perfection, making them an impressive yet simple dish to prepare at home.

Ingredients
- 3 king oyster mushrooms
- 1 inch ginger, minced
- 2 cloves garlic, minced
- 2 tbsp white miso paste
- 1 tbsp soy sauce
- 1 tbsp rice vinegar
- ½ tbsp sesame oil
- 1 tbsp sugar
- 1 tbsp olive oil (or vegan butter)
- 1 clove garlic, minced
- ¼ cup low sodium vegetable broth
- 1 stalk scallion, chopped
- ½ tbsp white sesame seeds (optional)
Instructions
- Step 1: Slice the king oyster mushrooms into 1-inch thick rounds. Score a criss-cross pattern on the top surface of each slice to help absorb the marinade.
- Step 2: In a bowl, whisk together the white miso paste, soy sauce, sesame oil, sugar, rice vinegar, minced ginger, and 2 cloves minced garlic. Pour this marinade over the mushroom slices and let them soak for 15 minutes to an hour to develop flavor.
- Step 3: Heat a pan over medium heat and add olive oil or vegan butter. Sauté 1 minced clove of garlic for about 30 seconds until fragrant.
- Step 4: Place the marinated mushroom rounds in the pan and cook the first side for 5 minutes or until nicely seared and caramelized.
- Step 5: Flip the mushrooms and cook the other side for 3 to 5 minutes. Add ¼ cup of vegetable broth to deglaze the pan, then allow it to simmer until the liquid evaporates.
- Step 6: Stir in the chopped scallions and cook for about 20 seconds. Remove from heat and serve immediately, garnished with extra scallions and a sprinkle of white sesame seeds if desired.
Tips & Variations
- For a richer taste, substitute olive oil with vegan butter for cooking.
- Adjust the marinating time depending on how intense you want the flavor; longer marinating yields a deeper taste.
- Add a splash of toasted sesame oil at the end for extra nutty aroma.
- Serve over rice or alongside steamed vegetables for a complete meal.
Storage
Store leftover cooked mushrooms in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat to maintain their texture and flavor. Avoid microwaving as it can make them rubbery.

FAQs
Can I use a different type of mushroom for this recipe?
King oyster mushrooms have a meaty texture that mimics scallops well, but you can try using large portobello or shiitake mushrooms. Keep in mind the texture and flavor will be different.
Is the miso paste important for flavor?
Yes, miso paste adds a savory umami depth that is key to the overall taste. If you don’t have white miso, you can use yellow miso, but avoid darker miso as it can overpower the dish.

Ingredients
Mushrooms
- 3 king oyster mushrooms
Marinade
- 1 inch ginger, minced
- 2 cloves garlic, minced
- 2 tbsp white miso paste
- 1 tbsp soy sauce
- 1 tbsp rice vinegar
- ½ tbsp sesame oil
- 1 tbsp sugar
Cooking
- 1 tbsp olive oil (or vegan butter)
- 2 cloves garlic, minced
- ¼ cup low sodium vegetable broth
- 1 stalk scallion, chopped
- ½ tbsp white sesame seeds (optional)
Instructions
- Prepare Mushrooms: Slice the king oyster mushrooms into 1-inch thick rounds and create a criss-cross pattern on the top of each slice to help the marinade penetrate.
- Make Marinade and Marinate: Whisk together white miso paste, soy sauce, sesame oil, sugar, rice vinegar, minced ginger, and 2 cloves minced garlic to form the marinade. Pour this marinade over the mushroom rounds and let them soak for at least 15 minutes, up to one hour, to absorb the flavors.
- Heat Pan and Sauté Garlic: Heat a pan over medium heat and add olive oil or vegan butter. Add 2 cloves minced garlic and sauté for about 30 seconds until fragrant, being careful not to burn it.
- Sear Mushrooms: Place the marinated mushroom slices in the pan, cooking the first side for approximately 5 minutes until nicely seared and caramelized.
- Flip and Simmer: Flip the mushrooms and cook the other side for another 3 to 5 minutes. Then add ¼ cup of low sodium vegetable broth to the pan to deglaze and let the mushrooms simmer until the liquid evaporates, allowing the mushrooms to soak up the savory sauce.
- Add Scallions: Stir in the chopped scallions and cook down for about 20 seconds to soften and meld the flavors.
- Serve: Serve the vegan scallops garnished with extra scallions and a sprinkle of white sesame seeds for a finishing touch.
Notes
- Marinating longer intensifies the miso and soy flavor in the mushrooms.
- The criss-cross pattern helps the marinade penetrate deeper and ensures even cooking.
- Use low sodium soy sauce and vegetable broth to control saltiness.
- For added richness, substitute olive oil with vegan butter.
- These vegan scallops pair well with rice, noodles, or a fresh salad.
