Oyster Sauce Substitute

If you’re halfway through a stir-fry or dipping sauce and realize you’re out of oyster sauce—don’t panic. You probably have a solid substitute already in your pantry. Whether you’re vegetarian, gluten-free, or just ran out, this guide will walk you through the best oyster sauce substitutes and when to use each one.

What is Oyster Sauce?

Oyster sauce is a thick, dark, savory sauce made from oyster extracts, sugar, salt, and cornstarch. It’s slightly sweet, deeply umami, and adds that rich, glossy finish to stir-fries, marinades, and dipping sauces. Common in Chinese, Thai, and Vietnamese cooking, it’s a go-to for quick flavor.

Think of it as the secret behind that savory depth in dishes like beef and broccoli, pad see ew, or Vietnamese thịt bò xào cải.

10 Best Substitutes for Oyster Sauce

These swaps will get you close to that signature flavor. Some are closer matches than others, but all work in a pinch depending on what you’re cooking.

1. Vegetarian Oyster Sauce (Best Overall Match)

If you’re looking for a one-to-one substitute, this is it. Made with mushrooms instead of oysters, it has the same thick texture and rich umami flavor. Great for stir-fries, noodle dishes, or any recipe that calls for oyster sauce.

Use 1:1 in any recipe.
Try the Lee Kum Kee Vegetarian Oyster Sauce—it’s widely available and tastes close to the real thing.

2. Mushroom Soy Sauce

Another great plant-based option. It’s thinner than oyster sauce but packs a strong umami punch from mushroom extract.

Start with a smaller amount and adjust to taste.
Add a pinch of sugar or a drop of cornstarch slurry if you want to mimic the thickness and sweetness.

3. Soy Sauce + Hoisin Sauce

This combo gets you pretty close! Soy sauce brings the salt and umami, while hoisin adds sweetness and body.

Mix 1 tablespoon soy sauce + ½ tablespoon hoisin sauce.

4. Tamari Sauce

Tamari is like soy sauce but usually gluten-free and a little less salty. It doesn’t have the sweetness of oyster sauce, but you can add a pinch of sugar to round it out.

Use as a 1:1 substitute.
Add sugar if your recipe leans sweet.

5. Dark Soy Sauce

This one’s thick and rich like oyster sauce but more intense and less sweet. It works well in darker sauces or glazes.

Use sparingly and adjust with a bit of sugar.
Best for recipes where color and depth of flavor matter.

6. Sweet Soy Sauce (Kecap Manis)

Popular in Indonesian cooking, this thick soy sauce is sweet and syrupy. It’s a good substitute for oyster sauce in Southeast Asian dishes.

Use as a 1:1 substitute, but watch the sugar content in your dish.

7. Hoisin Sauce

Hoisin sauce is thicker and sweeter than oyster sauce with notes of garlic and five spice. Not a perfect match, but works well in stir-fries and glazes.

Use 1:1 but expect a slightly different flavor profile.

8. Fish Sauce

Fish sauce is much saltier and thinner than oyster sauce. It’s not a great 1:1 swap on its own, but works if you just need a hit of umami.

Use sparingly (½ teaspoon at a time), and add sugar to balance.

9. Soy Sauce + Brown Sugar

Quick and easy pantry substitute. Mix soy sauce with brown sugar to mimic oyster sauce’s balance of salty and sweet.

Mix 1 tablespoon soy sauce + ½ teaspoon brown sugar.
Thicken with cornstarch if needed.

10. Anchovy Paste

Anchovy paste adds a big umami punch like oyster sauce, but it’s very strong and salty. Use it only in small amounts and pair with soy sauce or hoisin to balance the flavor.

Start with ¼ teaspoon and build from there.
