My keto stir fry sauce recipe is sweet, savory, and umami-forward. It ticks all the boxes, and my whole family loves using it on everything! 2 grams of net carbs.

My keto stir fry recipe is a regular player in our weekly dinner rotation, and if you know anything about stir fries, you know the trick comes down to having the perfect sauce.
Now, most stir fry sauces are either flavor-lacking or sugar-laden. But it doesn’t have to be that way. My homemade stir fry sauce has the same complex, savory, umami flavors as an authentic Asian sauce, but with a fraction of the carbs and calories!

Why I love this recipe
- Made with 6 simple ingredients. I made sure there were no overly complicated or niche ingredients required.
- Incredible taste. It’s sweet yet salty, with savory and umami notes–like an authentic Asian sauce should be.
- It’s fast. The xanthan gum thickens the sauce, so you don’t even have to simmer it.
- Versatile. Don’t let ‘stir fry’ fool you; we routinely use this sauce as salad dressing and as a marinade for our favorite proteins!
Key Ingredients
- Chicken or vegetable broth. I tried using both broth and water, and I preferred the added flavor of broth.
- Soy sauce. Use any gluten-free soy sauce, tamari, or coconut aminos.
- Fish sauce. This gives the sauce its umami flavor. Since we’re using such a small amount, it will have zero ‘fishy’ flavor whatsoever.
- White vinegar. Adds tanginess and helps the sauce stick to the protein and vegetables. Apple cider vinegar or unsweetened rice vinegar also works.
- Granulated sweetener. For essential sweetness and to balance the other flavors. I like to use keto brown sugar, but allulose is another good option as it dissolves exactly like sugar.
- Xanthan gum. Optional, but adding a dash of xanthan gum thickens the sauce while adding very few extra carbs.

Arman’s recipe tips
- Salad dressing. If you want to use this sauce as a dressing, I suggest skipping the xanthan gum and adding a splash of sesame oil to thin it out.
- Enhance the aromatics. Whisk freshly minced garlic, ginger, and green onions for a fresher flavor.
- Spice it up. Whisk in ¼ teaspoon of red pepper flakes.

If I don’t use keto brown sugar, what amount of traditional brown sugar should I use?
The same amount, Tom 🙂 It’s an equal substitution 🙂
