⭐ Soy Sauce (Best Fat-Free Option)
1 tablespoon soy sauce per 1 tablespoon fish sauceSoy sauce contains fermented soybeans that provide a rich umami flavor similar to fish sauce, making it an effective substitute in meatloaf where depth of flavor is key. The saltiness helps season the meat evenly.
When using soy sauce, choose a naturally brewed variety for better flavor and avoid low-sodium versions unless adjusting salt elsewhere. Monitor salt levels since soy sauce can be slightly less salty than fish sauce.
Compared to fish sauce, soy sauce results in a slightly milder aroma and flavor, which can be preferable in meatloaf to maintain a balanced taste without fishy notes.
