by Raksha Hegde last updated -

If you are on a ketogenic diet and looking for the best low-carbohydrate condiments, mustard certainly tops the list. Yellow mustard, made mainly with mustard powder and vinegar, is an all-American classic and can be your best bet to get rid of the pounds that you are aiming for. However, there are many mustard brands in the market and for a keto diet, it is essential to understand the carbohydrate content to make the best choices.

Is Mustard Keto-friendly?

Most mustard brands are keto-friendly condiments that don’t contain any carbohydrates. They can be made a part of your keto meal plan as a condiment, a base for salad dressings, and used in marinades as well as dips. However, certain brands may contain added sweeteners like honey or dried fruits as flavorings that can add to your carbohydrate intake. The standard ingredients in mustard are mustard seeds, distilled vinegar, salt, turmeric, water, garlic, and paprika. [1]

  • 3/4 cup yellow dry mustard powder
  • 1 cup water filtered
  • 3/4 tsp salt
  • 1/2 cup white distilled vinegar
  • 1/2 tsp turmeric powder
  • 1/8 tsp paprika
  • 1/8 tsp garlic powder


  • To make the mustard, warm water in a stainless steel saucepan and add dry mustard powder, water, salt, garlic powder, turmeric powder, and paprika. 
  • Keep stirring for 30-45 minutes on low heat till it becomes a thick, bubbly mixture. Make sure you open your windows and keep the area well-ventilated as the pungency can cause you to cough. 
  • Now, whisk the vinegar into the thick mixture little by little till it comes to the consistency that you prefer. This may take about 7-10 minutes. Take it off the heat. 
  • Let the prepared mustard mixture come to room temperature. Transfer it to a clean glass jar and refrigerate. You can use it for up to three months. 


It is important to use a stainless steel pot to make the mustard as aluminum or copper can cause it to have an off-color. You can also use glass or ceramic pots.
