Vegan Scallops & Garlic Butter Sauce

Vegan Scallops & Lemon Garlic SauceThese vegan scallops are made of king oyster mushrooms marinated with a vegan garlic butter sauce! Marinate ahead of time and cook them up in 10 mins!

A king oyster mushroom stem sliced looks like a scallop, and so all you really need to do is whip up my tasty marinade that the mushrooms can absorb and then fry it to become a vegan scallop! You can serve as an appetizer or add to one of my easy vegan pasta dishes.

king oyster mushroom scallopsNow, to get the best scallop taste, I highly recommend marinating the sliced mushrooms (aka vegan scallops) in a container the night before you fry them up alongside my quick garlic butter sauce. This allows the scallops to marinate for hours and absorb all the flavours. If you don’t want them too flavourful, you can just marinate for a minimum of 1 hour.

This is an original vegan recipe based on the one in my vegan cookbook that I’ve tweaked a little and is served with this new buttery garlic sauce.Vegan scallops

Lemon Butter Sauce
  1. With a vegetable brush, remove any dirt or debris from mushrooms and slice off the woody ends and mushrooms caps. Save the caps to use for another recipe like a stirfry.
  2. Slice the stems into 1 inch (2.5 cm) long pieces.
  3. In a large mixing bowl or Tupperware, whisk together hot vegetable broth, white miso, soy sauce or gluten-free tamari, kelp, and olive oil. Whisk until the miso has dissolved in the hot broth.
  4. Add the mushrooms and marinate for 15 mins to 2 hrs. Overnight is preferred.
  5. After your mushrooms have marinated, melt 1 tbsp vegan butter in a large skillet over medium-high heat.
  6. Working in batches, place marinated mushrooms, flat side down, and brown for 6-8 mins on each side. Set aside and keep warm.
  7. You can save time by making the garlic butter sauce in a seperate pan at the same time as frying the mushrooms, or save on dishes by using the same pan once all your mushrooms have cooked and are set aside.
  8. To make the garlic butter sauce, melt 2 tbsp vegan butter in the same skillet.
  9. Add garlic and cook, stirring frequently for 1 minute, or until fragrant.
  10. Stir in the lemon juice; season with salt and pepper, to taste.
  11. Serve mushroom scallops in a bowl or serving dish and pour the garlic butter sauce.
  12. Garnish with parsley.
  13. Enjoy as appetizer or add to a vegan creamy pasta dish

    I have just marinated my mushrooms! So excited to try it out. While not vegan, I added honey and some ghee to the marinade to try and replicate that sweet buttery profile of scallops. Will keep marinating for 5 hours. Can’t wait for the results!

  • Nancy says:

    King oysters are very hard to find around here. Is there any other mushroom that could be substituted?

  • Lisa says:

    made this for my 26 year anniversary tonight. Put “scallops” on top of vegan creamy polenta…it was amazing. Thank you for this lovely recipe. (Yummy)

  • Jackie says:

    My non-veg partner, who never gives out 10s, rated this an 8.5/10! He said it was suspiciously close to the real thing. I started the marinade before work one morning and we cooked it that evening so ~8hrs of sitting in the broth. I LOVED it and the lemon butter sauce was insanely good. I’m gonna make this whenever I see king oyster mushrooms at the store now.

  • Jared says:

    OMGosh. Fabulous! Sorry to say they didn’t make it as far as the appetizer stage of our vegan Labor Day cookout. The Hub ate most of them. Terrific recipe. Luckily, we have a wonderful Korean grocery where I can get king oysters. You rock. I’m making your vegan lobster rolls next.

    • EdgyVeg says:

      YAY! thanks so much Cat for this comment and 5-star review! Makes me so happy to hear they were a hit at your Labor Day cookout! It made me chuckle to hear your hubby ate most of them! I hope they were worth making again! Can’t wait to hear what you think of my lobster roll recipe 🙂
