What is the difference between hoisin sauce and oyster sauce?
Although both sauces are used in Asian cuisine, hoisin sauce is a rich, reddish-brown sauce that has a sweet-salty flavor and can be used as an ingredient or dipping sauce. Oyster sauce is more commonly used for adding salty umami flavor to food with a subtle taste of oysters. Oyster sauce is saltier and fishier than hoisin sauce but is also less sweet.
For both sauces, consistency will vary depending on the brand. Most hoisin sauces will have a thicker texture than oyster sauces.
Hoisin: soybeans, sesame seeds, chili, garlic, vinegar, sugar, spices, salt, starches, and water.
Oyster: oyster extract, water, sugar, salt, thickeners, flavors, starches.
Taste and Texture
Hoisin is a rich, reddish-brown sauce that’s packed with a combination of spicy, sweet, and salty flavors. It has a shiny smooth texture, similar to American barbecue sauce. Hoisin sauce is much less salty than fish sauce or soy sauce.
Oyster sauce offers a mix of salty, sweet, and umami flavors with a mild oyster undertone. This oyster taste may not be noticeable in better-quality brands. Although oyster sauce is salty, it is still a lot less so than soy sauce.
Fun fact: Although the word “hoisin” can be translated to mean “seafood” in Cantonese, there is no seafood in the sauce.

Can I use hoisin or oyster sauce interchangeably?
Although hoisin and oyster sauce have a distinctive flavor and color, you can swap one for the other in most recipes. Oyster sauce is saltier so we suggest using less or reduce the other salty ingredients in the dish. To replace oyster sauce with hoisin, you can use a similar quantity and then increase the saltiness with a splash of fish sauce. Keep in mind that hoisin sauce will add extra spicy, sweetness to your food. In most recipes, this change won’t be a deal-breaker.
As a dipping sauce, oyster sauce doesn’t make a good replacement for hoisin. It is very salty, so if you have to use it, try diluting with another milder sauce.
