How to Make Vegan King Oyster Mushroom Scallops with Garlic Lemon Butter Recipe

Step 1: Prepare the Mushroom Scallops

Begin by trimming the ends off your King Oyster mushrooms. Then, slice the stems into thick, 1-inch discs—these will be your “scallops.” Their thick, firm texture is perfect for mimicking the delightful bite of real scallops.

Step 2: Season and Oil the Mushrooms

Place the mushroom discs on a baking tray and brush both sides generously with olive oil. This step not only helps achieve that gorgeous sear but also prevents them from sticking while cooking. Sprinkle sea salt, ground black pepper, and paprika lightly over the top to build a savory and slightly smoky crust.

Step 3: Sear the Scallops

Heat a cast iron skillet over medium-low heat and add a thin layer of olive oil. Carefully place the mushroom “scallops” into the hot pan, seasoned side down—you should hear a satisfying sizzle that signals proper searing. While the first side cooks for around 2 minutes, season the other side with a bit more salt, pepper, and paprika. Flip the mushrooms once the bottoms turn golden brown and cook the other side for another 2 minutes. Repeat this process in batches until all the mushroom scallops are beautifully seared.

Step 4: Create the Garlic Lemon Butter Sauce

With the mushrooms finished and resting on the tray, add the vegan butter and crushed garlic to the same skillet used for searing (this is packed with flavor!). Let the butter melt and garlic cook gently for about a minute until fragrant and lightly golden—be careful not to let it burn. Stir in the freshly squeezed lemon juice and chopped parsley, then remove the pan from heat to retain the vibrant freshness.

Step 5: Coat the Mushroom Scallops

Return all the golden mushroom scallops to the skillet—it's perfectly fine to crowd them since you're just coating them in the sauce now. Gently move the scallops around to coat them evenly and spoon any extra garlic lemon butter over the top. This final step infuses every bite with rich, tangy flavor, tying together the whole dish beautifully.

Garnishes

To really make your dish pop, sprinkle a little fresh ground black pepper and chopped parsley over the top just before serving. Adding fresh lemon slices on the side not only brightens the plate visually but also offers guests a chance to add an extra burst of citrus zing if they desire.

Side Dishes

These vegan scallops pair wonderfully with light, fresh sides such as garlic sautéed greens, herbed quinoa, or creamy mashed potatoes. You could also serve them atop a bed of buttery pasta or alongside roasted asparagus to create an elegant and balanced meal.

Creative Ways to Present

For a stunning presentation that impresses, consider arranging the scallops in a circle or fan shape on the plate, drizzling extra garlic lemon butter sauce artistically around them. Garnish with a few microgreens or edible flowers to elevate the dining experience and bring a touch of sophistication to your vegan seafood feast.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers of this Vegan King Oyster Mushroom Scallops with Garlic Lemon Butter Recipe, store them in an airtight container in the refrigerator. They will stay fresh for up to 3 days, making for a quick and delicious meal later on.

Freezing

While freezing is possible, it’s best to freeze the mushroom scallops separately from the sauce to maintain optimal texture and flavor. Wrap the seared scallops tightly and freeze for up to 2 months. The sauce freezes well in a small airtight container or ice cube trays.

Reheating

To reheat, gently warm the scallops in a skillet over low heat, adding a touch of olive oil if needed. Pour the thawed garlic lemon butter sauce over the scallops and heat just until warmed through. Avoid microwaving to preserve that perfect texture and flavor.

FAQs
