Tasty Keto Stir Fry Sauce

Here’s my go-to keto stir fry sauce recipe that I’ve been using for the past year. It’s a simple mix of coconut aminos, sesame oil, ginger, and a few other low-carb ingredients that come together in just minutes.

This sauce has become my family’s favorite way to dress up any weeknight stir fry. I like to make a double batch and keep it in the fridge – it makes throwing together quick keto-friendly dinners so much easier. Nothing better than having a ready-made sauce when you’re hungry and short on time, right?

What Kind of Soy Sauce Should I Use?

For a keto stir fry sauce, the type of soy sauce you choose really matters since some varieties pack in hidden sugars. Traditional Chinese light soy sauce (not to be confused with low-sodium) is a great choice for stir-fries because it adds plenty of flavor without being too overpowering. If you’re watching your sodium intake, tamari or coconut aminos make good substitutes, though coconut aminos tend to be a bit sweeter so you might want to adjust your sweetener accordingly. Just be sure to check the label when shopping – you’ll want to avoid soy sauces with added sugar or corn syrup to keep things keto-friendly.

Options for Substitutions

This keto stir fry sauce is pretty easy to customize with what you have in your pantry:

• Chicken stock: Any stock works great here – beef, vegetable, or even plain water with a bouillon cube. For a richer sauce, try using bone broth.
• Soy sauce: For a gluten-free option, use tamari or coconut aminos. Keep in mind coconut aminos are slightly sweeter, so you might want to reduce the sweetener.
• Fish sauce: If you’re not a fan of fish sauce, you can leave it out and add an extra tablespoon of soy sauce plus a pinch of salt. The flavor won’t be exactly the same, but it’ll still taste good.
• White vinegar: Rice vinegar or apple cider vinegar work just as well. Each brings its own subtle flavor, but they all add that needed tang.
• Keto sweetener: Any sugar-free sweetener works here – monk fruit, erythritol, or allulose. Just make sure to adjust the amount based on your sweetener’s strength.
• Xanthan gum: This is important for thickening while keeping it keto. If you don’t need it to be strictly keto, you could use 1 tablespoon of cornstarch mixed with cold water instead.

Watch Out for These Mistakes While Cooking

The biggest challenge when making keto stir fry sauce is achieving the right thickness without using traditional cornstarch – adding too much xanthan gum can quickly turn your sauce into an unappetizing, gummy mess. Start with just a tiny pinch of xanthan gum (less than the recipe calls for) and gradually add more while whisking constantly until you reach your desired consistency. Another common mistake is adding the sweetener too early in the cooking process, which can lead to a bitter taste – instead, add it towards the end of cooking and adjust the amount to your taste. To prevent your sauce from becoming too salty, remember that both soy sauce and fish sauce are high in sodium, so taste as you go and consider using low-sodium soy sauce if you’re sensitive to salt. For the smoothest results, always combine your sauce ingredients in a separate bowl before adding to the pan, and keep the heat at medium-low while the sauce thickens to prevent any separation.

What to Serve With Keto Stir Fry Sauce?

This keto-friendly sauce works great with so many low-carb ingredients, making it perfect for your weekly meal prep! The sauce pairs wonderfully with cauliflower rice and your choice of protein – try it with chicken, shrimp, beef, or tofu. For extra flavor and crunch, throw in some keto-friendly vegetables like broccoli, bell peppers, mushrooms, and snap peas. You can also use this sauce to dress up simple zucchini noodles or shirataki noodles when you’re craving an Asian-inspired noodle dish without the carbs.

Storage Instructions

Keep: This keto stir fry sauce stays good in the fridge for up to 2 weeks when stored in an airtight jar or container. Give it a good shake or stir before each use, as the ingredients might naturally separate over time.

Make Ahead: You can whip up a double batch of this sauce and keep it ready to go! It’s such a time-saver for busy weeknight dinners – just pull it out whenever you need to jazz up your stir-fries or vegetables.

Note: If you notice the sauce has thickened too much in the fridge (thanks to the xanthan gum), just thin it out with a splash of chicken stock or water. The sauce isn’t suitable for freezing as it might affect the texture and consistency.

Ingredients

• 2 tbsp keto-friendly brown sweetener
• 1/2 tsp xanthan gum (for thickening, sifted to prevent lumps)
• 1 tbsp fish sauce (Red Boat is a good option)
• 1 tbsp white vinegar
• 3 tbsp soy sauce
• 1/2 cup chicken stock (low sodium preferred)

Step 1: Prepare the Sauce

In a large mixing bowl, combine the following ingredients to make your flavorful stir fry sauce: chicken broth, soy sauce, fish sauce, white vinegar, keto brown sugar, and xanthan gum.

Whisk these ingredients together until they are thoroughly mixed and the xanthan gum is fully dissolved.

This mixture will provide a rich and tangy base for your stir fry.

Step 2: Add the Sauce to the Stir Fry

Once your vegetables and protein are mostly cooked to your liking in your favorite stir fry recipe, pour the prepared sauce into the pan.

Ensure the pan is on medium heat to help the sauce thicken and coat the ingredients evenly.

Stir continuously as the sauce blends with the other ingredients, allowing the flavors to meld and creating a delicious glaze over your stir fry.

Cook for an additional few minutes until everything is well-coated and heated through.
