🍳 What You'll Need for This Recipe
Essential tools to make this recipe perfectly
This recipe isn’t just about throwing ingredients together; it’s about building layers of flavor. Here’s why it works so well:
- Fermented Black Beans: The star of the show! These beans provide that signature salty, pungent, and slightly sweet flavor that defines black bean sauce. We’ll show you how to properly prepare them to maximize their deliciousness.
- Aromatic Base: Garlic, ginger, and scallions create a fragrant foundation that complements the black beans perfectly. Sautéing them in oil releases their essential oils, infusing the sauce with depth.
- Balanced Flavors: A touch of sugar, soy sauce, and rice wine vinegar balances the saltiness of the black beans, creating a harmonious flavor profile.
- Thickening Power: Cornstarch slurry provides the perfect consistency, coating your ingredients in a glossy, flavorful sauce.
- Customizable Heat: A pinch of red pepper flakes (or a dash of chili oil) adds a touch of heat, which you can adjust to your preference.
Ingredients
- 2 tablespoons fermented black beans, rinsed and coarsely chopped
- 2 tablespoons vegetable oil
- 4 cloves garlic, minced
- 1 tablespoon ginger, minced
- 2 scallions, thinly sliced, white and green parts separated
- 2 tablespoons soy sauce
- 1 tablespoon rice wine vinegar
- 1 tablespoon sugar
- 1 teaspoon cornstarch
- 2 tablespoons water
- Pinch of red pepper flakes (optional)

Instructions
- Prepare the Black Beans: Rinse the fermented black beans thoroughly under cold water to remove excess salt. Coarsely chop them and set aside. Rinsing is crucial; otherwise, the sauce will be overwhelmingly salty.
- Sauté the Aromatics: Heat the vegetable oil in a wok or large skillet over medium heat. Add the minced garlic, ginger, and white parts of the scallions. Sauté for about 1 minute, or until fragrant, being careful not to burn the garlic.
- Add Black Beans: Add the chopped black beans to the skillet and sauté for another minute, stirring constantly. This step helps to release their flavor.
- Create the Sauce: In a small bowl, whisk together the soy sauce, rice wine vinegar, and sugar. Pour this mixture into the skillet with the black beans and aromatics.
- Thicken the Sauce: In another small bowl, whisk together the cornstarch and water to create a slurry. Pour the cornstarch slurry into the skillet and stir constantly until the sauce thickens, about 1-2 minutes. The sauce should be glossy and coat the back of a spoon.
- Add Finishing Touches: Remove the skillet from the heat. Stir in the green parts of the scallions and red pepper flakes (if using).
- Taste and Adjust: Taste the sauce and adjust the seasoning as needed. You may want to add a pinch more sugar for sweetness, a splash more rice wine vinegar for acidity, or a dash of soy sauce for saltiness.
- Use Immediately: Use the black bean sauce immediately in your favorite stir-fry, noodle dish, or other recipe.
Tips for Success
- Quality of Black Beans: The quality of your fermented black beans will greatly impact the flavor of your sauce. Look for black beans that are plump and fragrant.
- Don’t Overcook the Garlic: Burnt garlic can make the sauce bitter. Keep a close eye on it and reduce the heat if necessary.
- Adjust the Sweetness and Acidity: Everyone has different preferences. Don’t be afraid to adjust the amount of sugar and rice wine vinegar to suit your taste.
- Control the Heat: If you’re sensitive to spice, start with a very small pinch of red pepper flakes or omit them altogether. You can always add more later. Chili oil is another great option for adding heat.
- Use a Wok (If You Have One): A wok is ideal for stir-frying because its sloped sides allow for even cooking and prevent ingredients from sticking. However, a large skillet will also work well.
- Prepare Ingredients in Advance: This sauce comes together quickly, so it’s best to have all your ingredients prepped and ready to go before you start cooking. This is called “mise en place” and is a key to successful cooking.
Storage Instructions
Store leftover black bean sauce in an airtight container in the refrigerator for up to 5 days. The sauce may thicken slightly in the refrigerator, so you may need to add a splash of water when reheating. You can also freeze the sauce for up to 2 months. Thaw it in the refrigerator overnight before using.

FAQ
- Can I use dried black beans instead of fermented black beans? No, dried black beans are not a suitable substitute. Fermented black beans have a unique flavor and texture that is essential to the sauce.
- Where can I find fermented black beans? Fermented black beans can be found in most Asian grocery stores. They are usually sold in small bags or jars. You may also be able to find them online.
- Can I make this sauce without sugar? While the sugar balances the saltiness, you can reduce or omit it if desired. Consider using a natural sweetener like honey or agave nectar in a smaller quantity.
- My sauce is too salty. What can I do? If your sauce is too salty, try adding a little more sugar and rice wine vinegar to balance the flavors. You can also add a splash of water to dilute the saltiness. Next time, make sure you rinse the black beans very thoroughly.
- What dishes can I use this black bean sauce in? The possibilities are endless! Use it in stir-fries with vegetables and protein, as a sauce for noodles, as a marinade for meat, or as a dipping sauce for dumplings.
