If you have a gluten intolerance or follow a gluten-free diet, you can still indulge in the flavors of Mongolian Beef with this gluten-free recipe. The traditional soy sauce is replaced with gluten-free tamari or coconut aminos, and the cornstarch is substituted with a gluten-free alternative like arrowroot powder or tapioca starch. The result is a gluten-free Mongolian Beef that is just as delicious as the original, without any gluten-containing ingredients.
