Soy Sauce with Lime Juice (Best Option)
1 tablespoon soy sauce + 1 teaspoon lime juice per 1 tablespoon fish sauceSoy sauce provides the salty and umami base similar to fish sauce, while lime juice adds the bright acidity that fish sauce naturally contains. This combination balances the savory and tangy notes essential in fried rice.
For best results, add lime juice gradually and taste as you go to avoid excessive sourness. Use a light or low-sodium soy sauce to prevent overwhelming saltiness.
Compared to fish sauce, this substitute yields a slightly less pungent but well-rounded flavor, preserving the authentic taste profile of fried rice without fish-derived ingredients.
