What is Peanut Sauce?

Peanut sauce is also known as satay sauce and has its origins in Indonesia, located in Southeast Asia (the peanut being a Mexican crop introduced to the region by the Spanish and Portuguese merchants), however other countries including Thailand, Malaysia, and even China have their versions of satay. The authentic method for making a satay is by grinding up peanuts that have been roasted and salted and adding them to coconut milk, tamarind, soy sauce, galangal, garlic, and other spices. Sometimes sugar, chilis, and lemongrass are used in the sauce recipe. This sauce is often served with vegetables, meats, and chicken skewers called “satay.” The consistency (thickness) of the peanut sauce depends upon the amount of water added to the recipe, which is up to the discretion and a matter of one’s taste.
Is Peanut Sauce Keto-Friendly?
It depends on the recipe, however, peanut sauce is typically not keto-friendly – especially if it is pre-packaged. Ingredients like tamarind and brown sugar are very high in carbohydrates. The peanut butter and coconut milk may also have added sugars. Here is the breakdown of the authentic, high carb Thai peanut sauce ingredients:
Ingredient | Carbohydrates (grams) |
coconut milk (sweetened) | 6.5 |
brown sugar | 18 |
tamarind paste | 2.2 |
These ingredients add an additional 6.6 grams of carbohydrates per serving (not including the peanut butter).
Tamarind paste is a key ingredient in authentic Thai peanut sauce with a sour/citrus/molasses flavor. Equal parts lime juice and brown sugar (or golden erythritol, for a keto recipe) is a good substitute.

- Measuring Set – to ensure the flavors are correctly balanced by measuring each ingredient
- Whisk – by properly mixing the ingredients, the texture of the sauce will be smooth and creamy
Ingredients
- Peanut butter – choose a creamy texture with only peanuts and salt listed in the ingredients
- Soy sauce – gives the peanut sauce its rich salty flavor (see below for gluten-free alternatives)
- Golden erythritol – this brown sugar substitute will give the sauce a sweet, deep molasses flavor without the carbs
- Lime juice – adds the acidic and sour element to this recipe: fresh or bottled works fine
- Chili flakes – the amount of heat may be adjusted according to taste
- Hot water* – add as much necessary to achieve the desired consistency for the peanut sauce

What Kind Of Peanut Butter Is Keto-Friendly?

Only Packaged peanut butter that contains peanuts, and sometimes, salt, is keto-friendly. These brands are often labeled “all-natural” or “no added sugars,” however, you should always read the label to be sure. Peanuts are keto-friendly at 8.6 net carbs per cup and can be consumed in moderation on the keto diet.
Peanut Butter With Added Sugars | 22 grams |
Peanut Butter With No Added Sugar | 14 grams |
Of course, you can always make your own peanut butter by placing roasted peanuts into a food processor and blending until your desired consistency is achieved.
Is Keto Peanut Sauce Gluten-Free?
This keto peanut sauce recipe contains soy sauce, which also contains wheat, and therefore it contains gluten. However, substitutes like Tamari (100% soy) or coconut aminos made from coconut blossom nectar (both wheat and soy-free) may be used in place of regular soy sauce in this recipe to make it gluten-free.

How To Store The Low-Carb Peanut Sauce
If making this keto peanut sauce ahead of time or will store leftovers, refrigerate in an air-tight container for up to a week. The sauce will thicken in the cold temperature, you will need to “loosen” the sauce by reheating it on a stovetop or in a microwave-safe container on low heat, taking care not to boil the peanut sauce as it will have the opposite effect (thicken) through evaporation. Add more water or lime juice if needed to thin out the sauce.
