Oyster Sauce Substitutes:

Don’t have the sauce at home or readily at hand? Can’t go out or don’t have the time to drop by the grocery store? Here are some oyster sauce alternatives to help you with the dish.

  • Hoisin sauce vs oyster sauce – Is hoisin sauce the same as oyster sauce? No, the “oyster” sauce is as the name states it, is a sauce made from oysters simmered and mixed with salt and sugar till its caramelized, adding cornstarch as a thickener to create a thick buttery brown to black-brown colored sauce. While Hoisin sauce is not made of animals, it is plant based made of fermented soybeans, with a similar coloring to the first sauce. Both have a similar consistency but hoisin sauce is not as sweet and is saltier. The best alternative to use, some just add more sugar to make it slightly more similar.
  • Oyster sauce vs soy sauce – the easiest to find alternative, can be vegetarian or vegan though the texture is less thick so if one were to make a sauce with it and would like to thicken it, try simmering it with potato starch or cornstarch, adding some sugar to get that sweetness to make a bit it more similar.
  • Oyster sauce vs Fish sauce – similarly to soy sauce it is not at all thick, and is the saltiest out of the 3 alternatives.
