These Chinese Buffet-style Mushrooms are one of my favorite side dishes at the Chinese buffet. They are plump, juicy, and so fun to eat. My mom used to get mad at me for filling myself up with them because she said they were cheap and easy to make.
In a small bowl, combine the oyster sauce, water, soy sauce, dark soy sauce, and cornstarch. Set it aside for later.
In a large skillet, heat one tablespoon of oil over high heat. Add the mushrooms and cook for 3 minutes until they reduce in volume by about 20%.
Reduce the heat to medium. Push the mushrooms to one side of the pan and add another tablespoon of oil to the empty space. Add the garlic and cook for 20-30 seconds.
Give the sauce mixture a stir then pour it into the skillet. Mix everything to coat in the sauce and keep cooking it until the sauce thickens. If the sauce is too thick, you can add extra water to thin it out. Transfer to a serving dish and serve!
