Dijon Mustard Substitute
Out of mustard, dislike the flavor or cooking for someone who's allergic to it? Use one of these mustard substitutes to get dinner on the table.
Make Your Own Mustard
If you have dry mustard (also referred to as ground mustard) in your pantry, making your own mustard is a cinch. Just combine one teaspoon of dry mustard with one teaspoon of vinegar and one teaspoon of water. Allow the flavors to develop for 15 minutes. Then, use in place of one Tablespoon of prepared mustard.
This basic, no-frills mustard recipe works well as a stand in for yellow mustard, and will work for spicier mustards (dijon/spicy brown mustard) in a pinch.
Out of dry mustard, too? Grind mustard seeds to create the dry mustard that you need for this substitute. White or yellow mustard seeds have a mild flavor (they're used to make yellow mustard). Brown mustard seeds have more of a bite. Black mustard seeds have a strong flavor, and make the hottest mustards. Be sure to consider heat, when choosing which mustard seeds to use.
If you don't have the ingredients you need to make your own mustard, or you need to omit the mustard from a recipe to accommodate dietary restrictions or personal tastes, there are other ingredients that you can use in its place. To make a successful substitute, it's important to consider how the mustard is being used in the recipe. Mustard adds flavor to a dish, certainly, but it may also be used as a thickener or emulsifying agent (something that helps to hold oil and vinegar together).
The type of mustard called for is also important to consider. Yellow mustard is fairly mild in flavor, while Dijon or whole seed mustard is far spicier. Taking this into account, allows you to pick a substitute with the closest flavor match.
With that said, here are some substitutes to consider:
For Yellow Mustard - Try an equal amount of mayonnaise. This won't give you the same flavor, but it will maintain the thickness.
For Dijon Mustard or Spicy Brown Mustard - Use a small amount of prepared horseradish or Wasabi in its place. Both pack a lot of heat, so just a dab will do it (definitely don't replace it measure for measure). If mustard allergies are a concern, check the label before using Wasabi. It's sometimes made with ground mustard.
For Salad Dressings/Vinaigrettes - Omit the mustard from vinaigrettes. The oil and vinegar won't hold together as well, but it'll still taste good. For salad dressings, where mustard is a main ingredient, it's best to choose another recipe.
For Cooked Dishes - If the recipe only calls for a small amount of mustard, you can usually get away with skipping it. This is especially true, when there are other herbs and spices in the dish.
