If your oyster mushroom stir-fry tends to release a lot of liquid or turns soft and soggy, removing excess moisture before stir-frying is the key.
For this recipe, the oyster mushrooms are not blanched. Instead, they are first dry-cooked in a skillet with a pinch of salt to release excess moisture, then quickly stir-fried over high heat with aromatics and seasonings. This method helps reduce the amount of liquid that collects even after the dish sits and keeps the mushrooms pleasantly chewy.
The savory depth of oyster sauce and soy sauce pairs with the gentle sweetness of onion and green onion for a clean, flavorful Korean side dish.

✓ How to Make Oyster Mushroom Stir-Fry
- Prepare the mushrooms: Trim off any dirty ends from 200 g (7.1 oz) oyster mushrooms, then tear them into bite-size strips.
- Rinse and drain the mushrooms: Gently swish the mushrooms in water to clean them, then immediately transfer them to a colander and shake off the excess water.
- Prepare the vegetables: Cut 1/3 stalk green onion into 2–3 cm (about 1 inch) pieces. Slice 1 onion into thick strips. Remove the seeds from 1 red chili pepper and cut it into thin strips about the same length as the mushrooms.
- Dry-cook the mushrooms: Heat a skillet without adding oil. Add the oyster mushrooms and 1 pinch of salt, then stir continuously with a spatula until the mushrooms release their moisture.
- Set the mushrooms aside: Once the excess moisture has cooked off and the mushrooms become chewy, transfer them to a plate and let them cool slightly.
- Sauté the aromatics: Add 45 ml (3 tbsp) cooking oil to the skillet. Add 1/3 tbsp minced garlic, the green onion, and the onion. Sauté over medium heat until the onion becomes translucent.
- Season and finish over high heat: Once the onion is translucent, add the dry-cooked oyster mushrooms, red chili pepper, 15 ml (1 tbsp) soy sauce, 15 ml (1 tbsp) oyster sauce, a few shakes of black pepper, and 7.5 ml (1/2 tbsp) corn syrup. Stir-fry quickly over high heat for about 1 minute, then serve.
✓ Key Tips for Success
- Dry-cook instead of blanching in salted water: Blanching mushrooms in boiling salted water can cause them to hold onto more moisture, which may make them soft and watery after stir-frying. Dry-cooking them first with a pinch of salt helps draw out excess moisture and keeps the texture pleasantly chewy.
- Finish over high heat for about 1 minute: If the mushrooms and vegetables are cooked too long over low heat after the seasonings are added, they can release more liquid. Once everything is combined, stir-fry quickly over high heat for about 1 minute so the sauce coats the ingredients evenly and develops a glossy finish.
✓ Serving Tips
- Serve the stir-fried oyster mushrooms over warm rice with a fried egg, then add a small amount of gochujang or sesame oil for a simple bibimbap-style meal.
- The gentle heat from the red chili pepper helps keep the dish from tasting heavy, making it a clean and savory everyday side dish.
✓ How to Choose Good Oyster Mushrooms
- Cap surface and color: Choose mushrooms with smooth, intact caps and an even light gray color.
- Gills underneath the caps: The gills should be clearly defined rather than crushed or flattened, with a clean white color.
- Stem firmness and thickness: Choose mushrooms with stems that feel firm and springy rather than soft when touched.

✓ Frequently Asked Questions (FAQ)
Q1. Should I avoid washing oyster mushrooms for too long?
Yes. Oyster mushrooms absorb moisture quickly, so rinse them briefly under running water or gently swish them in water, then drain them immediately to help preserve their chewy texture.
Q2. Why does oyster mushroom stir-fry become watery after cooking?
This usually happens when the mushrooms are not dry-cooked first to release excess moisture or when they are stir-fried too long over low heat after adding the sauce. Dry-cook them first with a pinch of salt, then finish quickly over high heat to minimize excess liquid.
Q3. Can I season the dish with only soy sauce if I do not have oyster sauce?
Yes, you can make it with soy sauce alone. However, if you want to make up for the deeper savory flavor and glossy finish of oyster sauce, you can add a small amount of fish sauce or tuna extract sauce to the soy sauce.
Following this recipe and dry-cooking the oyster mushrooms with a pinch of salt before adding the seasonings helped them stay pleasantly chewy without releasing excess liquid. The savory oyster sauce and soy sauce coated the mushrooms evenly, while the onion and green onion added a gentle sweetness that made the dish especially good with rice.
I usually prefer mushroom stir-fries with a firm, chewy bite rather than a soft and watery texture, and this version held onto that springy texture until the end. My family also enjoyed serving the well-seasoned mushrooms over rice because the dish stayed flavorful without becoming soggy.
If you want to make a clean, chewy oyster mushroom stir-fry without excess moisture, dry-cook the mushrooms first and finish everything over high heat for about 1 minute. The ingredients and cooking process are simple, making this an easy Korean side dish to add to your regular meal rotation.
