Dijon mustard is usually easy to budget in a small portion using this estimate of 1.8g net carbs per 100 g. A 10 g serving contributes about 0.2g within a 20–25 g daily budget. The estimate is generic; check the actual jar rather than assuming a Dijon-style sauce has the same recipe.

WHY IT'S KETO-FRIENDLY
- Use Dijon as an ingredient in a dressing, then count oil, juice and any sweetener separately. A finished mustard dressing is not nutritionally identical to its mustard component.
- Compare plain Dijon with honey Dijon and sandwich sauces. The word Dijon may describe the flavor even when the product includes substantial ingredients beyond mustard.
- When brushing it onto meat before cooking, measure the amount used on that portion. Mustard left in a mixing dish does not have to be treated as an eaten serving.
PREPARATION SUGGESTIONS
MAKE A MEASURED MUSTARD SAUCE
Weigh a small Dijon portion into the sauce bowl before mixing. Divide the sauce according to how it is served, and include anything sweet added to balance the flavor.
Better keto swaps
- Spicy Brown Mustard — 1.8g net carbs per 100 g (reference). A related mustard choice when a more textured condiment suits the dish; use its own label rather than assuming the recipes match.
- Garlic Mayo — 0.6g net carbs per 100 g (estimate). For a creamy sandwich spread, garlic mayo serves a different flavor role. Its estimate does not represent a mustard-and-mayo blend.
