Vegan Scallops (King Oyster Mushroom Scallops)
Being vegan does not mean you cannot enjoy sea-flavors using plant-based ingredients. Besides my recipes for carrot lox, chickpea tuna salad and vegan fish nuggets, these mushroom scallops are again proof of how easy and simple it is to make amazing cruelty-free alternatives at home!

When sliced and aromatically marinated, the stems of oyster mushrooms will look and feel amazingly similar to the famous scallops after frying. The marinade mixture of tamari, miso paste, maple syrup and nori seaweed will give the mushrooms a great salty, culinary and fresh sea flavor that is absolutely delicious.
Slathered in a rich vegan lemon garlic butter sauce that further elevates the dish into something you would expect from restaurants rather than just your kitchen. These vegan scallops are made to impress and easy to plate up for a fancy dinner party or date night. Everyone will love them, vegans, vegetarians and non-vegans alike!


Ingredients Needed
Vegan Scallops
- King oyster mushrooms: this low-carb superfood vegetable is also called king trumpet mushrooms, and they are loaded with fiber, vitamins, and minerals. They are ideal because their stems are thick and round and look exactly like scallops when sliced. They cook to look, feel, and taste so much like scallops; you’ve got to try it to believe it!
- Vegetable broth: I recommend using high quality, organic and low-sodium variety to keep this recipe as healthy as possible.
- Tamari: adds a savory and umami flavor to the mushrooms. You can also use soy sauce or sub coconut aminos for a soy-free alternative.
- Miso paste: This condiment has that quintessential umami flavoring and salty-sweet richness that makes this dish so flavorful! In case you cannot find any, you can sub with vegan Worcestershire sauce or more tamari or soy sauce.
- Maple syrup: adds a tone of sweetness to cut through all the savoriness of the marinade. You can also use agave, date syrup, or regular sugar.
- Nori: this is responsible for the briny, fish-like flavor of the mushrooms. Some great alternatives for this would be dulse or kelp flakes.

Lemon Garlic Butter
- Vegan butter: You can use canola or olive oil, but butter gives the sauce a richer, unbeatable taste.
- Garlic cloves: provide a sharp, savory punch of flavor to the sauce.
- Lemon juice: adds a bright and tangy tone to the garlic butter sauce.
- Salt and pepper: to taste.
- Fresh parsley: for garnishing.

How to make Vegan Scallops
As always, I recommend checking out this step-by-step instruction and the recipe video first. Then you’ll find the full recipe with exact measurements in the recipe card below!
Step 1: Cut and marinate mushrooms
Cut the stems of the oyster mushrooms into about 1-inch (2.5 cm) thick slices. Optionally, score the cut-sides crosswise with a sharp knife. Next, mix together all the ingredients for the marinade. Then pour it over the mushrooms and toss to coat. Leave to marinate, covered, for at least 30 minutes (or refrigerate overnight).
Note: You can use the caps of the mushrooms for another recipe like mushroom risotto or mushroom wellington.

Step 2: Cook vegan scallops and lemon garlic butter
Heat a tablespoon of vegan butter in a skillet or non-stick pan. Add the marinated mushrooms and sauté for about 6-8 minutes per side until golden brown.
Meanwhile, melt the remaining vegan butter in another pan. Press in the garlic and sauté for a minute. Season with lemon juice, a little salt and pepper. Drizzle the lemon garlic butter over your king oyster mushroom scallops and garnish with fresh parsley. Serve over pasta, mashed potatoes, bruschetta or avocado toast as desired!

Tips when making Vegan Scallops
- Do not throw away the caps of the mushrooms. Put them to good use to make other recipes like Creamy Mushroom Risotto or Mushroom Wellington.
- Scoring the sliced mushrooms will allow the marinade to seep right through, so do not forget to do this.
- Marinate the mushrooms overnight to give them more time to absorb all the flavors. All you have to do is saute and make the sauce the next day.
- Use a cast-iron skillet if possible. The even, consistent heat from the pan will give you that perfect seared surfaces that will deliver tons of smoky flavor to your king oyster scallops.
- You can use other vegan sauces than lemon garlic butter, such as creamy white Alfredo sauce, or a simple balsamic vinaigrette.
How to store leftovers?
Leftover scallops can be stored in a sealed container in the refrigerator for up to 5 days. However, you can also freeze them for up to 3 months. When ready to serve, simply reheat in a skillet, pan or microwave.

Wow these were amazing and so easy. Maybe a little too much lemon but it could have been just a juicy lemon. I used coriander instead of Parsley.
Awesome! Glad you enjoyed them! Thank you! 🙂
Didn’t have the nori but even without this is sooooo good! I haven’t eaten scallops before so can’t speak as to how scallopy they are, but they are DELICIOUS.
I’m so glad you liked them! 🙂 Thank you so much for the great feedback! ♡
