Simple homemade Chinese-style black bean sauce – made with fermented black beans (sometimes known as salted black beans).
The beans just need a short 30-60 minute soak, then they’re ready to be made into a quick, rich, umami stir fry sauce.

The jar is on a dark surface and there are ingredients scattered around.

I love making stir fry sauces, as they’re usually so simple – calling for little more than a splash of various ingredients from a number of bottles, plus a little garlic and ginger.

Black bean sauce always intrigued me though, as it contains something I’d never used before. Black beans of course.
Now we’re not talking tinned or dried black beans. Black bean sauce calls for fermented black beans, also known as douchi. These are black soy beans that have been fermented and salted.

I’ve got to admit, I didn’t really want to go to the (6 month+) effort of fermenting black beans myself, but fortunately you can buy them in packs, ready fermented!

📋 Ingredients?

Ingredients for homemade black bean sauce on a wooden board.

Most of the ingredients for black bean sauce are very easy to source from practically any mid-size supermarket. It’s just the beans which may be a little more difficult to find.

You should be able to pick them up at any Asian supermarket, or if you don’t have one nearby, then Amazon also sells them.

We only need 4 tablespoons of fermented black beans to make a cup of black bean sauce (which should serve about 4 people), so I’d advise going with the smaller packet, unless you’re looking to make LOTS of black bean sauce.

  • The red packet (<–affiliate link) shown below is a 100g pack. I use about a third of this pack to make a jar of black bean sauce.
  • The white pack (<–affiliate link) is 500g! I bought a big pack because I knew I’d be doing lots of testing.

Fortunately they last for ages. An opened pack should be stored in a sealed container in the fridge. They should happily last for a year in there.

Full recipe with detailed steps in the recipe card at the end of this post.

  1. First we soak the fermented black beans in cold water for about an hour. After this time, drain and rinse the beans. The beans are very salty, to be sure to rinse well.
  2. Squish the beans up a bit with the back of a fork. Leave roughly a quarter of the beans whole, the rest can be squashed to a lumpy paste.
  3. Fry garlic and ginger in oil with the black beans. Then add rice wine, soy sauce, rice vinegar, sugar, pepper and stock.
  4. Simmer together for about 5 minutes. Thicken the sauce with a little cornflour slurry, then turn off the heat and it’s ready to use.

👩‍🍳PRO TIP The sauce will be on the salty side, but once you’ve fried it up with meat and vegetables, it will taste perfectly balanced. You can use reduced sodium stock if you’re worried about it being too salty for your taste.

🍽️ How to use it

  • Stir fried with chicken, tofu or vegetables
  • Stir fried with beef and vegetables for a tasty beef in black bean sauce ⬇️

If you don’t want to use the sauce right away, you can cool it, then store in a sealed container/jar in the fridge for 2 weeks.
