What is Black Bean Sauce?
Chinese black bean sauce, also known as Chinese black bean paste, is a savory and pungent condiment made from fermented black beans, also known as douchi. Black bean sauce is a staple ingredient in Cantonese and Sichuan cuisine and is used in a wide variety of dishes, including stir-fries, braises, and marinades.

Black Bean Sauce Ingredients
This DIY black bean sauce uses just a handful of ingredients but they’re all key in delivering flavor and balance. Here’s what you’ll need:
- Fermented black beans: This is where the real magic happens with their incredibly deep, umami-rich flavor.
- Garlic: This deliver pungency, umami, subtle sweetness and tremendous depth.
- Ginger: With its spicy flavor and invigorating fragrance, it contributes a warming kick.
- Green onions: These add a mild onion flavor.
- Chinese rice wine: Very fragrant with a slightly sweet and briny flavor.
- Soy sauce: This provides the needed salt along with a bold umami flavor.
- Rice Vinegar: Less acidic than white vinegar, it’s adds a delicate and somewhat sweet flavor along with its balancing tang.
- Hot pepper sauce: For some contrasting kick to tie it all together.
What Are Fermented Black Beans?
Let’s talk about the central ingredient in black beans sauce: Fermented black beans. No, they’re not your typical black beans, aka turtle beans, that you find in dishes like Black Beans and Rice or in South American cuisine. Fermented black beans are actually black soybeans. These fermented black soybeans, called douchi in Chinese, are created through a process of boiling the beans, then inoculating them with a special mold spore (commonly aspergillus oryzae) as they dry in the sun. Then they’re typically either stored dry or in brine. This same mold variety is used in miso and soy sauce which are also both fermented products. Because of their strong flavor, fermented black beans are frequently paired with other strong flavors like, most commonly garlic and also chilies for heat. You can find fermented black beans in well-stocked Asian grocery stores or you can buy them online. They usually come in a large quantity and at a good price. They’ll keep for a long time, several months, and you can also freeze them in ziplock bags and they’ll last even longer.

Black Bean Sauce Recipe
Let’s get started!
Place the fermented black beans in a small bowl, cover with water and soak for an hour or so. Then rinse and drain them. Mash the beans up with a fork and set them aside.

Heat the oil in a small sauce pan over medium-high heat and cook the garlic and ginger for a minute or two until softened and very fragrant.
Add the green onions and cook for another minute.

Add the mashed fermented black beans and cook for another minute.

Add the remaining ingredients, except for the cornstarch, and bring to a boil. Reduce the heat to medium and simmer for 10-12 minutes or until the liquid has been reduced by half.

Stir in the cornstarch mixture and simmer for another minute or until thickened.

Let the black bean sauce cool and then store it in the fridge in an airtight container, preferably a glass jar. Will keep for up to 2 weeks.

How To Use Black Bean Sauce
Black bean sauce is used any time you want to add a unique and powerful flavor boost to your dishes along with a punch of umami. Sharp, pungent, salty and spicy with a hint of sweet, it contributes flavor Chinese food like nothing else. And it’s potent, so a little goes a long way. For a flavor boost try adding a little to your favorite Chinese dishes like Chinese Beef and Broccoli, Mongolian Beef, Mongolian Chicken, Kung Pao Chicken, and Shanghai Noodles. Some other great ways to use it include:
- Stir-fries, fried rice, noodles, and tofu
- Eggs and omelettes (including Egg Foo Young)
- Chinese long beans or green beans
- Chicken, pork, beef, fish and seafood
- Asian eggplant dishes
- Steamed vegetables such as bok choy or broccoli
- Asian wraps (check out my Thai Lettuce Wraps)
- Grain salads like my Asian Wheat Berry Salad
I especially love including it in the base for most any stir-fry. Just select your protein, throw in some veggies, and add some black bean sauce with your other sauce ingredients.

This was a very tasty sauce and it was even better when I tried it the following day. I used it in a stir fry the first day and used the leftover black bean sauce in some Chinese noodles.
Thank you, Tina, I’m so glad you enjoyed it and I agree with it tasting even better the following day!
This is an excellent black bean sauce. It took some time to find the fermented black beans but it was well worth it.
Thank you, Natalie, I’m so glad you enjoyed it!
I’ve made this twice already, this time also using it to make your hoisin sauce. Both of these sauces are truly excellent.
I’m so glad you made and enjoyed both of them, thank you Nathan!
Hey, if I was to make a stir fry for two, how much of this sauce would you use? Look forward to trying it.
Hi Steve, I would aim for 2 tablespoons or so. Give the stir a fry a taste and then determine if you want to add even more. Happy cooking!
I pre make this sauce, usually multiplying X6 to feed a crowd. I use brown sugar and since I like a hint of sweet, I triple the called-for amount of sugar. This gets rave reviews by my friends. Thank you!
Awesome, Tracey, thank you so much!
Excellent
Hi can you freeze it
Hi Wayne, yes you can. Cornstarch breaks down though when thawed so you might have to reheat and re-thicken it.
Thank you for answering Wayne. I was just wondering the same thing.
Great recipe! I was planning to use arrowroot instead of cornstarch (usually works about the same) but I found after cooking down the liquid that the sauce was plenty thick without adding it. Tastes fantastic!
Awesome, thank you so much, Jimmy!
