Ingredient Breakdown

King oyster mushrooms take the spotlight in this dish with their firm, chewy texture that mimics meat. When torn into strips or thickly sliced, they develop a beautiful sear and a savory depth that anchors the entire stir-fry.

Garlic and ginger work in tandem as aromatics, adding pungency and warmth that balance the umami-rich sauce. While ginger is optional, it brings a brightness that contrasts the earthiness of the mushrooms.

For a pop of color and a mild bite, bell peppers or Anaheim chilies are a welcome addition. They contribute visual appeal and a subtle sweetness that lifts the savory notes.

The sauce is a blend of oyster sauce (or a vegan substitute), soy sauce, and a touch of sugar. This trio creates the classic sweet-salty-umami foundation that clings to each mushroom piece. A hint of black pepper adds depth, while cornstarch ensures the sauce thickens into a glossy, cohesive coating.

To finish, chili oil or flakes bring optional heat, and a drizzle of sesame oil adds nutty fragrance just before serving.

Step-by-Step Preparation Guide

Start by thoroughly cleaning the mushrooms and choosing your preferred shape—slicing them into coins, tearing them into pieces, or shredding them for a pulled texture. This versatility allows you to play with how the mushrooms cook and absorb flavor.

In a small bowl, whisk together all sauce components: oyster sauce, soy sauce, sugar, pepper, and cornstarch slurry if desired. Preparing this in advance ensures a smooth and efficient cooking flow.

Heat your pan over medium-high heat until the oil shimmers. Begin with the aromatics—garlic and ginger—letting them sizzle until golden and fragrant. This creates a base layer of flavor that permeates the dish.

Add the mushrooms and allow them to sear undisturbed for a moment before tossing. This encourages caramelization and prevents sogginess. Stir-fry for several minutes until they’ve softened and developed color.

If including bell peppers or similar vegetables, add them now and stir-fry briefly. They should remain vibrant and crisp, bringing contrast to the softened mushrooms.

Pour the sauce into the pan and stir constantly, coating everything evenly. In a minute or two, the sauce should thicken and begin to cling to each piece, creating a luscious glaze.

Remove from heat, sprinkle with fresh scallions, and, if desired, drizzle sesame oil or chili oil to finish. Serve hot for the best texture and flavor.

Recipe Tips

Best slicing technique for the meatiest texture:
Tear or slice mushrooms into thick pieces rather than thin ones to encourage a hearty bite.

How to prevent mushrooms from becoming soggy:
Use high heat and avoid overcrowding the pan; this helps them brown instead of steam.

When to add cornstarch slurry for ideal consistency:
Add the slurry at the end once the mushrooms are fully cooked, allowing it to thicken the sauce in under two minutes.

Tips for adjusting spice levels based on preference:
Add chili oil at the end for control, or use sliced fresh chili during cooking for stronger heat.

Timing your stir-fry to keep all ingredients crisp and flavorful:
Cook mushrooms until browned first, then add vegetables briefly to keep them crisp-tender.

What to Serve With This Recipe

Pair this mushroom stir-fry with a bowl of steamed jasmine or brown rice to soak up the rich sauce. For a heartier option, toss it with rice noodles or serve it over sesame-oil-dressed soba.

A side of crisp cucumber salad or cabbage slaw dressed in sesame vinaigrette adds a cool, crunchy contrast. For a multi-course meal, serve with a simple miso or clear broth soup to balance the richness.

Frequently Asked Questions

Can I make this completely vegan?
Yes. Use mushroom-based soy sauce instead of oyster sauce, and ensure any broth used is vegetable-based.

Do I need to use cornstarch in the sauce?
Not necessarily. It helps create a thick, glossy finish but can be skipped for a lighter consistency.

What other vegetables work well in this stir-fry?
Try adding snow peas, broccoli florets, shredded cabbage, or baby corn for more texture and color.

Can I store leftovers and reheat later?
Yes, though the texture is best fresh. Store in an airtight container in the fridge and reheat quickly in a skillet to retain some crispness.

Is there a substitute for oyster sauce?
Use mushroom sauce, hoisin sauce, or a mix of soy sauce and a touch of molasses or miso paste for similar depth.

Creative Variations

For added protein, toss in cubes of tofu or tempeh alongside the mushrooms. If you’re aiming for more crunch, snow peas or water chestnuts offer excellent contrast. You can also use chili crisp instead of plain chili oil for more intense, layered heat.
To transform this stir-fry into a noodle topping, double the sauce ingredients and toss everything with freshly cooked noodles for a saucy, umami-packed dish.

Ingredients

4 King Oyster Mushrooms, cleaned and sliced, shredded, or torn into bite-sized pieces
4 cloves garlic, finely chopped or minced
½ to 1 inch piece of ginger, minced (optional)
1–2 tablespoons cooking oil (vegetable, sesame, or peanut oil)
Red bell pepper or Anaheim pepper, thinly sliced (optional, for color and mild heat)
Spring onions or scallions, chopped (for garnish)

Sauce Mix

1–2 tablespoons oyster sauce (or mushroom-based soy sauce for a vegan option)
1 tablespoon soy sauce (light or dark, adjust to taste)
1 teaspoon sugar
¼ teaspoon black pepper (optional)
1 teaspoon cornstarch mixed with a splash of water or chicken broth (optional, for thickening)
Chili oil or red chili flakes (optional, for added heat)

Instructions

Start by preparing the king oyster mushrooms. Rinse them under cold water and pat dry. Slice them into ¼-inch rounds or strips, or use a fork to create a shredded texture by scoring and pulling them into strands.

In a small mixing bowl, whisk together the oyster sauce, soy sauce, sugar, black pepper (if using), and the cornstarch slurry (if using). Stir until the mixture is smooth and set aside.

Heat a large skillet or wok over medium-high heat. Add the cooking oil and let it heat until shimmering. Toss in the garlic and ginger and stir-fry for about 30 seconds to 1 minute, or until aromatic and just beginning to turn golden.

Add the mushrooms to the pan and stir-fry for 3 to 5 minutes. Keep the heat high to drive off moisture quickly and encourage browning and caramelization. The mushrooms should soften and reduce slightly in size, developing a golden exterior.

If using bell peppers or other vegetables, stir them in at this point and cook for another 1 to 2 minutes until they’re vibrant and slightly tender.

Pour the sauce mixture into the pan, stirring continuously to ensure the mushrooms are evenly coated. Let it cook for another 1 to 2 minutes, allowing the sauce to thicken and glaze the mushrooms.

Turn off the heat. Finish the dish with a garnish of fresh spring onions or scallions and, if desired, a light drizzle of sesame oil for extra aroma. Serve immediately with a bowl of steamed rice for a delicious, satisfying meal.
