1. Turmeric

Turmeric is a potent spice commonly used in Indian cooking. However, it is most known for its health benefits and medicinal properties, which help boost the immune system, fight off inflammation, and even help maintain the heart’s health. 

This spice has an intense golden yellow color and an earthy and mildly spicy flavor that resembles that of mustard seeds.  It is a great substitute to use in place of mustard seeds as it delivers the same spicy kick. 

It also works well in the same kinds of dishes mustard seeds are typically used for. You can use the powdered form or the freshly ground paste to get a stronger flavor.

How To Substitute

Use a 1:1 ratio when substituting turmeric for mustard seeds.

However, keep in mind that turmeric has the tendency to slightly change the color of some dishes, so it may be best to only use it in making sauces and soups.

2. Wasabi

Wasabi is a root plant of the Brassicaceae family of plants. With its distinct green color and pungent aroma, wasabi is a common condiment used in many Japanese cuisines. In fact, it is sometimes called Japanese horseradish. 

It has a flavor profile similar to mustard seeds, and it is spicy but not so hot that it overwhelms the palate. Instead, its flavor fills the nose with a sharp aroma and kick of flavor, making it an ideal mustard seed substitute. 

Since it often comes in a grounded paste, wasabi is a great ingredient to add to dishes like soup and stews or as a condiment for sushi.

How To Substitute

Use half a tablespoon of wasabi for every tablespoon of mustard seeds.

3. Mustard Powder

Mustard powder is a spice made from ground mustard seeds. Since its majorly composed of mustard seeds, it is probably one of the best substitutes for the seeds.

Mustard powder possesses a sharp, spicy, and pungent flavor that is identical to that of seeds, so you can use it in any dish that calls for mustard seeds. 

Just like seeds, you can use mustard powder in making savory soups, stews, and salad dressing or use it as a dry rub for meats.

Mustard powder is a common staple in Indian cuisines, but its distinctive flavor can be incorporated into dishes from all around the world.

How To Substitute

When replacing mustard seeds with mustard powder, use half a teaspoon of mustard powder for every teaspoon of mustard seeds required.

If the recipe calls for more than that, simply divide whatever amount is needed by half and use that amount of mustard powder.

4. Horseradish

Horseradish is another root vegetable from the same Brassicaceae family that wasabi belongs to. It is known for its many health benefits. It is rich in Vitamin C and antioxidants and has been shown to have cancer-fighting properties. 

Horseradish has a pungent and spicy flavor that matches that of mustard seeds. It also leaves a slight mustard-like taste on the palate, so it is an excellent substitute for mustard seeds. 

Eating horseradish raw might leave you overwhelmed with a sensation of heat, but incorporate it with other ingredients, and you’ll get a truly worthy replica of mustard seeds. 

While it is commonly used as a condiment, horseradish can actually be used for a wide variety of different dishes.

How To Substitute

5. Whole Grain Mustard

Whole grain mustard is a type of prepared mustard made from mustard seeds that have ground to form a paste.

Since the seeds are not ground into a completely smooth texture, this prepared mustard is much thicker and grittier than regular mustard. 

In terms of flavor, whole grain mustard is a great substitute for mustard seeds as it packs the same strong nutty, and spicy flavor of mustard seeds. 

It is commonly used as a condiment, but as a mustard seed substitute, you can use it for just about anything, from pickling to sauces and even salad dressing.

How To Substitute

Although you can find whole-grain mustard at your local grocery store, you can also make them from scratch if you prefer. Here’s a video to help you with the steps-

6. Caraway Seeds

Caraway seeds are the dried fruit of the aromatic caraway plant. They have been used in many parts of the world throughout the years for their medicinal properties, but they also make a great addition to different cuisines.

The flavor of these seeds intensifies during cooking, so they are an excellent substitute for mustard seeds if you’re looking for something to add to sauces and soups.

How To Substitute

Use a 1:1 ratio when substituting caraway seeds for mustard seeds. However, if you find that the seeds alone do not deliver the right amount of heat and pungent flavor, then combine them with some freshly ground cumin.

7. Prepared Mustard

If you’ve ever looked at the bottle of your favorite store-bought mustard, you’ll notice it is made from mustard seeds, vinegar, and a few other ingredients.

This makes it a great substitute to use in place of mustard seeds when you run out of options. 

Prepared mustard has a mildly spicy and pungent aroma similar to that of mustard seeds and could easily impart the same flavors into any dish.

How To Substitute

The amount of prepared mustard needed will depend on the recipe. However, a good rule of thumb is to use two teaspoons of prepared mustard for each teaspoon of mustard seeds.

Since they are combined with other ingredients, most prepared mustards are often quite mild in comparison to mustard seeds. So, if you want to get the same strong flavor of mustard seeds, a little modification will be required. That might mean combining it with some horseradish or wasabi.

8. Nigella Seeds

Also known as black seeds, nigella seeds are another group of seeds known for their medicinal and culinary properties.

They are rich in antioxidants and have been shown to reduce inflammation in the body, regulate blood sugar, and have potential cancer-fighting properties.

 They also bring a rich flavor to curries and soups, so if you’re making an Indian dish that requires mustard seeds, nigella seeds are the perfect alternative to try.

How To Substitute

Use a 1:1 ratio when replacing mustard seeds with nigella seeds.

9. Mustard Oil

Mustard oil is a pressed cooking oil derived from mustard seeds. It is rich in omega-3 fatty acids, antioxidants, and other nutrients that are essential to the body. 

This oil also has the same pungent flavor and spicy aroma that mustard seeds possess, making it an excellent substitute for mustard seeds.

It is an ideal replacement to use when you can’t get your hand on any other spices we’ve mentioned, as cooking with this oil will ensure the main base of your dish has a robust mustardy flavor.

It is commonly used in Asian cuisines but can be incorporated into any kind of cuisine as long as you add it in moderation.

How To Substitute

Use two tablespoons of mustard oil for each tablespoon of mustard seeds required when substituting.

10. Harissa Paste

Harissa paste is a North African chili paste made from a blend of chilis, caraway seeds, and a host of other different species. It has a smoky, peppery flavor that adds a lovely kick of spice to different foods. 

If all you’re looking for is something to deliver that spicy mustard seed flavor, harissa is a great substitute to try. This paste works best as a marinade for meats and veggies, but it can also be added to sauces and stews.

How To Substitute

Use half a tablespoon of harissa for each teaspoon of mustard seeds.
