Oyster sauce can be found in a variety of Chinese and Asian recipes, including many of the recipes on this site. It’s also included in our list of 10 Essential Chinese Pantry Ingredients, for good reason.
A sauce made from oysters may sound a little bit scary, but it is actually quite mild, and adds a blast of flavor and umami to dishes.
As Bill’s father, a chef, used to say, “if you want to make any dish taste better, just add oyster sauce.”
What is Oyster Sauce? What Does It Taste Like?
Oyster sauce (háo yóu, 蚝油) is a savory sauce including oyster extracts and other seasonings like sugar and sometimes soy sauce.
Traditionally, the sauce was made by simmering oysters in water until the liquid caramelized and reduced into a flavorful sauce. Today, manufactured versions include sugar, salt, and cornstarch thickeners, with oyster flavoring and sometimes MSG (though you can find MSG-free versions).
As for the taste, it doesn’t actually taste strongly of oysters. It’s much less funky than say, fish sauce. Instead, it’s salty, sweet, and savory. It’s a dark brown color and quite thick, with a viscosity and texture similar to ketchup or barbecue sauce.
How Is It Used?
Oyster sauce features primarily in Cantonese cooking, but Chinese chefs in other regions also prize it for its umami-enhancing capabilities. It can essentially serve as an all-purpose seasoning for tofu, meat, vegetable, and seafood dishes. Add a teaspoon or two to just about anything, and you won’t be disappointed with the result.
We’ll often add a teaspoon or two of oyster sauce to meat marinades for stir-fries, and add a tablespoon to sauces and braises.
One vegetable side dish, common in dim sum and other Cantonese restaurants, is as simple as it gets. It features blanched leafy greens like Chinese broccoli or choy sum, drizzled with oil, perhaps a dash of sesame oil, and of course, oyster sauce. Check out our recipe here.
This ingredient is also a heavy hitter in one of Sarah’s favorite dishes: our Ultimate Braised Tofu, adding umami and richness to an otherwise vegetarian dish.
To really get an idea of how great this stuff is, though, try our Sticky Oyster Sauce Chicken. This condiment/seasoning is the true star of this incredibly simple dish. When you’ve tasted the chicken and rich sauce over a bed of steamed rice, you’ll understand why Chinese cooks love it.
Buying & Storing Oyster Sauce
You’ll see different brands at different price points in the Chinese grocery store. Avoid any products that are less than $2 or any found in the “ethnic” section of a local mega mart. They likely have artificial flavorings.
It’s best to buy a higher quality, more expensive product in your local Chinese market or online. Even an expensive bottle should be less than $5 or $6. One bottle will last you a long time, even if you cook our recipes a few times a week!
We generally use Lee Kum Kee’s Premium Oyster Sauce. (Lee Kum Kee’s founder, Lee Kum Sheung, is said to have accidentally invented the stuff when he left a pot of oysters boiling for too long.)
In the photo below, you’ll see Lee Kum Kee’s standard product on the left, and their premium product on the right. The standard stuff usually costs between $2-3, while the price of a premium bottle is usually around $5.
Refrigerate after opening. It will last in the fridge for 1 year, as long as you don’t dirty the bottle or cross contaminate with other ingredients. (In our experience, we’ve kept it even longer without a problem. Use your best judgment).
If you don’t have an Asian grocery store near you, you can find it online. It’s important to note, however, that purchasing online is generally significantly more expensive. If you do have access to a Chinese grocery store, we highly recommend venturing in for all the ingredients you need!
Gluten-Free & Vegetarian Versions
Gluten-free: Regular versions often contain wheat flour, but luckily, Lee Kum Kee makes a gluten-free version. Look for the Lee Kum Kee Panda Brand Oyster Sauce with the green label. It’s also MSG-free!
Vegetarian: For vegans and vegetarians, some brands offer an “oyster sauce” flavored with mushrooms instead of oysters. Find out more about the vegetarian version here.
Substitutions for Oyster Sauce
If you don’t have oyster sauce or its vegetarian equivalent, and it isn’t the main flavor agent of the dish, you can substitute a vegetarian stir-fry sauce:
