How to Make King Oyster Mushroom Scallops (Vegan Scallops) Recipe
Step 1: Make the Garlic Herb Butter
Start by combining softened vegan butter with freshly minced garlic and chopped parsley. This simple mix will become the decadent sauce that brings everything together at the end. The garlic imparts a warm punch while the parsley keeps it fresh and vibrant.
Step 2: Marinate the King Oyster Mushrooms
Next, mix hot water with oil, kelp flakes, and salt in a shallow dish to create a marinade that infuses those unmistakable umami and sea-inspired flavors. Clean your king oyster mushrooms under cool water, then carefully trim off the tough ends and slice the stems into rounds about a quarter-inch thick. Scoring each round with diagonal cuts allows the marinade to soak in deeply, ensuring every bite bursts with flavor. Pop the mushroom slices into the marinade for at least 15 minutes, or up to 3 hours in the fridge if you want to prep ahead.
Step 3: Cook the Scallops
Heat a skillet over medium-high heat and add a tablespoon of oil. Drain the mushrooms from their marinade and place them carefully into the hot pan. Let them cook undisturbed for about 3 to 4 minutes so they develop a gorgeous golden crust before flipping to cook the other side equally. Once both sides are perfectly seared, turn off the heat and add the garlic herb butter along with a squeeze of fresh lemon juice to the pan. This last touch not only dissolves the butter into a silky sauce but also brightens the dish with citrusy freshness.

Side Dishes

Creative Ways to Present
For a dinner party, serve these scallops atop a bed of vibrant sautéed greens or nestle them alongside roasted seasonal vegetables for a colorful and nutritious plate. You could even skewer the mushroom rounds and grill them lightly for a unique presentation. Drizzle extra garlic herb butter right before serving to impress your guests with that glossy finish.
Make Ahead and Storage
Storing Leftovers
Store any leftover King Oyster Mushroom Scallops (Vegan Scallops) in an airtight container in the refrigerator for up to 3 days. Keep the garlic herb butter separate if possible, and add it fresh when reheating to preserve the vibrant flavors.
Freezing
While these vegan scallops are best enjoyed fresh for maximum texture, you can freeze cooked mushrooms in a freezer-safe container for up to one month. Thaw overnight in the fridge before reheating gently.
Reheating
Reheat gently in a skillet over medium-low heat to preserve that tender bite and avoid drying out. Add a little vegan butter or oil if needed, and freshen with a squeeze of lemon to revive the bright flavors after reheating.
FAQs
Can I use other mushrooms for vegan scallops?
King oyster mushrooms are ideal because of their thick, meaty texture that holds up well when cooked, but you can experiment with large portobello or trumpet mushrooms. Just keep in mind the texture and size will vary.
What if I don’t have kelp flakes?
If you don’t have kelp flakes on hand, a splash of soy sauce or tamari can provide some umami depth, though it won’t quite replicate the oceanic hint of kelp.
Is this recipe gluten-free?
Yes! All the ingredients in this King Oyster Mushroom Scallops (Vegan Scallops) Recipe are naturally gluten-free, just double-check any packaged items like vegan butter or kelp flakes to be sure.
Can I prepare the mushrooms in advance?
Absolutely. You can marinate the mushroom slices up to 3 hours ahead and keep them refrigerated. This makes day-of preparation quick and easy.
What’s the best oil to use?
Choose a neutral oil like canola or light olive oil to get a nice sear without adding extra flavor that competes with the delicate scallop notes.

Ingredients
For the Mushroom Scallops
- 2 large king oyster mushrooms (aka trumpet mushrooms)
- 2 tablespoons neutral flavored oil (like canola or light olive oil), divided
- 1 teaspoon kelp flakes
- ¼ teaspoon sea salt
- ¼ teaspoon garlic powder
- 2 tablespoons hot water
For the Garlic Herb Butter
- 4 tablespoons vegan butter, softened
- 2 cloves garlic, minced
- 1 tablespoon fresh parsley, chopped
- 1 tablespoon lemon juice
Instructions
- Make the garlic herb butter: In a bowl, mix 4 tablespoons of softened vegan butter with 2 cloves of minced garlic and 1 tablespoon of fresh chopped parsley until well combined. Set aside for later use.
- Prepare the marinade: In a shallow dish, combine 2 tablespoons of hot water with 1 tablespoon of oil, 1 teaspoon of kelp flakes, and ¼ teaspoon of sea salt. Stir to dissolve the salt and distribute the kelp flakes evenly.
- Prepare the mushrooms: Rinse the king oyster mushrooms under cool running water to remove dirt or debris. Using a sharp knife, cut off the brown top section of the mushroom stem and remove the tough bottom part. Slice the stem into approximately ¼-inch thick rounds. Score the rounds by cutting crisscross diagonal lines about halfway through each piece to allow the marinade to penetrate better.
- Marinate the mushroom scallops: Place the sliced mushrooms into the prepared marinade, ensuring they are well coated. Let them sit for at least 15 minutes; they can be refrigerated and marinated for up to 3 hours prior to cooking.
- Cook the scallops: Heat a large skillet over medium-high heat and add the remaining 1 tablespoon of oil. Remove the mushroom slices from the marinade, draining off excess liquid. When the pan is hot, add the mushrooms and cook for 3 to 4 minutes on each side until nicely browned and tender.
- Add finishing touches: Once the mushrooms are cooked, turn off the heat and add the prepared garlic herb butter and the juice of ¼ lemon to the pan. Toss gently to coat the mushrooms with the flavorful butter sauce.
- Season and serve: Season with additional salt and pepper to taste. Garnish with fresh parsley and lemon wedges. Serve the vegan scallops over your favorite base such as rice, quinoa, mashed potatoes, risotto, or pasta for a satisfying meal.
