📝 Editor's Notes
Bulgogi-flavored king oyster mushroom stir-fry is a sweet and savory side dish that everyone, young and old, loves, thanks to the chewy king oyster mushrooms coated in bulgogi (불고기) seasoning.
It's simple to make without complicated steps, making it easy for even beginner cooks to try.
The key to this dish is ensuring the mushrooms' moisture is fully evaporated to achieve a chewy texture.
It's perfect for a busy weeknight dinner or as a packed lunch side dish, and an excellent choice when you want a hearty vegetable dish instead of meat.
🛒 Ingredient Tips
For this dish, choose plump, firm, and glossy king oyster mushrooms.
Look for clean, rounded caps and stems that are not dry at the ends, indicating freshness.
Since mushrooms absorb too much water when washed, which can make them mushy, prepare them by gently wiping with a damp towel.
Select onions with dry, firm skins that are not soft, and green onions that are vibrant in color and not wilted, as fresh ingredients will enhance the flavor of your dish.
🔄 Substitution Guide
You can use other mushrooms instead of king oyster mushrooms.
Enoki mushrooms or oyster mushrooms will result in a softer texture than king oyster mushrooms, but you'll still enjoy their distinct aromatic flavor.
However, enoki mushrooms have a high water content, so adjust the cooking time to be shorter.
If green onions are unavailable, you can use diagonally sliced white or green parts of a large green onion as suggested in the recipe.
Large green onions have a stronger aroma and sweetness than green onions, offering a different appeal.
If you don't have oyster sauce, you can add an additional 1/2 tbsp soy sauce and 1/4 tbsp sugar, and a little dashi (다시마) stock to compensate for the umami.
The depth of flavor might be slightly different, but it will still be delicious.
🥘 Ingredients
👨🍳 Cooking Points
There are two key cooking points for this bulgogi-flavored king oyster mushroom stir-fry.
First, when stir-frying the mushrooms, ensure you thoroughly evaporate the moisture over medium-low heat.
After quickly searing the surface over high heat, reduce to medium-low and gently stir-fry to allow the moisture inside the mushrooms to escape, resulting in a chewy and elastic texture.
Second, after adding the seasoning, stir-fry the onion and green onions very briefly over high heat to maintain their crisp texture.
If you stir-fry them for too long, they will become soggy and lose their appealing texture, so turn the heat to high for only 30 seconds to 1 minute.
Keeping these two points in mind will help you make delicious mushroom stir-fry every time.
👨🍳 Directions
Gently wipe the king oyster mushrooms with a damp towel. Be careful not to wash the mushrooms with water.
Slice the king oyster mushrooms lengthwise into thin strips.
Thinly slice 1/4 of an onion into strips.
Cut 5-6 stalks of green onions into 2 to 2.5-inch (5-6 cm) lengths. (If green onions are unavailable, you can use about half a stalk of a large green onion instead.)
Combine 2 tbsp soy sauce, 1 tbsp white sugar, 1/2 tbsp oyster sauce, and 1/2 tbsp minced garlic to make the seasoning sauce.
Heat 1 tbsp cooking oil in a pan over high heat, then add the sliced king oyster mushrooms.
Lightly flip the mushrooms, then reduce the heat to medium-low and stir-fry until the moisture from the mushrooms evaporates.
Once the mushrooms become tender, slightly shrunken, chewy, and begin to develop a glossy sheen, add all of the prepared seasoning sauce.
Stir-fry well over medium-low heat until the sauce is evenly absorbed by the mushrooms.
Once the mushrooms are well-seasoned and beautifully colored, raise the heat back to high, then add the sliced onion and green onions.
Stir-fry the onion and green onions briefly.
Drizzle with 1/2 tbsp sesame oil, add about 3 shakes of black pepper, then sprinkle with 1/2 tbsp toasted sesame seeds. Stir quickly and turn off the heat. It's done.
💡 Tips
