From the Sichuan Province of China, Szechuan sauce is a sweet and spicy combination of soy sauce, vinegar, sugar, garlic, and spiciness!
This sauce gets its name from the Szechuan region of China, where Sichuan peppercorns are generously used.
These special peppercorns can be best described as having a spicy flavor and a mouth-numbing effect. This sauce is intended to be used in a stir-fry that uses Sichuan peppercorns and does not contain any on its own. We made this optional.
Because of this unique, and to many unpleasant, feeling, most American Szechuan dishes do not include the famed peppercorn. I do highly encourage you to try them — it is a unique feeling that is numbing, but not in heat or spice. You can find them online, in an Asian grocery store, and in the Asian section of many large grocery stores.
What is Szechuan Sauce?
Hailing from the Sichuan Province of China, this Szechuan sauce is a sweet and spicy sauce. It’s a combination of soy sauce, vinegar, sugar, garlic, and an element of heat which can be added using Sichuan peppercorns or other ingredients. This recipe calls for red pepper flakes with the option of using the peppercorns.
Ingredients
You may already have most of these simple ingredients in your pantry, which means you can easily whip this sauce up whenever you want!
- Low-Sodium Soy Sauce – Using a low-sodium sauce lets you better control the saltiness of the Szechuan sauce. If you prefer for it to be more salty, you can add more salt after combining the ingredients. Be sure to check the label if you’re trying to make your sauce gluten-free.
- Black Vinegar or Rice Vinegar – Either of these types of vinegar will balance the sauce with its acidity. Black vinegar adds another layer of umami flavor, but since it can be challenging to find sometimes, you can substitute rice vinegar instead.
- Brown Sugar – You can use either light or dark brown sugar. Dark brown sugar will give the sauce a more molasses-style flavor.
- Fresh Garlic – You can either mince or grate the garlic but be sure that it’s in very small pieces so that it combines well with the other ingredients.
- Crushed Red Pepper Flakes – Red pepper gives the sauce its spiciness. You may want to adjust based on your palate, and if you’re using the peppercorns.
- Sichuan Peppercorns – While optional, these peppercorns give the sauce its signature flavor.
- Cornstarch – Cornstarch is used in this recipe to thicken the sauce.
- Water – You’ll need to mix the cornstarch with water before you add it to the sauce.
