Worcestershire Sauce
3.30g net carbs per 1 tbsp
Splashed into marinades or pan sauces, one tablespoon brings 3.3 g net carbs, mostly from the molasses and sugar used to make it. Measure it rather than free-pouring, since a couple of careless splashes can add up fast in a strict day.

Good to Know
The carbs here come mostly from sugar and molasses, so check the label closely. Lea & Perrins lists high fructose corn syrup, while some brands use plain sugar. A few low-sugar versions exist (Primal Kitchen makes a no-added-sugar Worcestershire-style sauce), and those can cut the carb count meaningfully. Watch the anchovy and tamarind base too, since a teaspoon often delivers plenty of savory depth, meaning you rarely need a full tablespoon to season a dish.
Is Worcestershire Sauce Keto? The Full Answer
Worcestershire Sauce contains 3.30g net carbs per 1 tbsp (3.30g total carbs minus 0.00g fiber). Splashed into marinades or pan sauces, one tablespoon brings 3.3 g net carbs, mostly from the molasses and sugar used to make it. Measure it rather than free-pouring, since a couple of careless splashes can add up fast in a strict day.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 16% of a 20g daily carb limit. Track your portions carefully and account for other carbs in your meals.
Better Keto Swaps
Coconut aminos taste close to that savory, slightly sweet tang, but watch the pour since they still run about 1 g net carbs per teaspoon. A splash of regular soy sauce or tamari gives you the salty umami depth for roughly 0.5 g net carbs per tablespoon, much lower than the 3.3 g here. For a near-zero option, try a few dashes of fish sauce (Red Boat is a clean pick) at about 0.2 g net carbs per teaspoon. It brings the same funky savoriness to marinades and pan sauces.
