Whether it is steak or lasagna, onion salt can make them super tasty and even better than green onions. But what happens if you run out of this ingredient?

What Does Onion Salt Taste Like?

So, what is onion salt? What does onion salt taste like?

Onion salt is a combination of onion powder, salt, and an anti-caking agent keeping the mixture smooth for a long time. Therefore, the flavor of onion salt is a mixture of sweetness, sulfur, and pungency of the touch of onion powder and the savory coming from the salt.

5 Ingredients Can Used As An Onion Salt Substitute

Onion salt can improve the flavor of your dish more than regular salt. With this ingredient, you don’t even need to take your time to prepare onions. However, you might run out of it while working on a savory dish. Here are some substitutes for onion salt for your recipe:

1. Onion Powder – The Best Choice

You may wonder, can you substitute onion salt for onion powder? This is probably the perfect substitution for onion salt as it is the main component of onion salt!

Onion salt is basically a combination of onion powder, salt, and anti-caking ingredients. Therefore, onion powder can completely grasp the flavor that onion salt brings to your recipe.

Onion powder is one of the common kinds of spices made from dehydrated and ground onion bulbs. This ground spice has a pungent flavor of sweetness, garlic, and sulfur, bringing the natural taste of onion to your dish.

This ingredient is popular for dishes that require the taste of onion but not too strong such as dry rubbing on chicken breast, steaks or lean pork chops, soups, tomato sauce, and salad dressing.

To substitute for onion salt, you need to make some adjustments to the onion powder to have a similar taste. Firstly, you need to check how much onion salt the recipe is asking in order to measure properly.

Then take a mixing bowl and put in onion powder in this ratio:

For every teaspoon of onion salt, you will take ¼ teaspoon of onion powder. Then, add a fair amount of salt corresponding to the teaspoon of onion powder. Normally, I would take around ¾ teaspoon of salt for each ¼ teaspoon of onion powder.

2. Onion Flakes – Similar Ingredient

Another great substitution for onion salt is onion flakes. Similar to onion powder, onion flakes are produced from minced and dehydrated fresh onions. To make onion flakes, the fresh onions are chopped and dried in the sun or a dehydrator.

The difference is onion flakes are in a thin oval shape instead of powder form. They can be used as an onion salt replacement in stews, soups, and other dishes. Once they are dried, their size shrinks tremendously into small flakes. Then people will store them for six months before use in order to achieve a tasty flavor.

You can use them for marinating meat, salad dressings, or soups. There are two ways for you to use onion flakes instead of onion salt. You can use them in a recipe in normal form or grind them into onion powder.

If you’re using them directly in your dish, you need to note that ½ teaspoon of onion flakes combined with ½ teaspoon of salt equals one teaspoon of onion salt.

3. Grated onion – Same Flavor

Onion salt is just a dehydrated fresh batch of onion combined with salt to save more time from chopping onions. Therefore, it is completely understandable to substitute onion salt with real grated onion and salt.

This mixture can also help you control the flavor of your ingredients and the level of sodium intake, which can cause high blood pressure if you overuse it.

With the finely grated onions, you can easily replicate the flavor of onion salt in many recipes. However, grating fresh onion can have small bulks, which is not preferable for thin soups and salad dressings.

When adding onions, there will be more moisture to your dish, so you need to modify the amount of the liquid in your recipes.

Furthermore, the fresh onions can have a stronger taste and odor than onion salt, so you need to keep in mind the amount of grated onion usage.

In order to substitute onion salt with grated onions, you can grate 1/4 of a medium-sized onion and add ½ teaspoon of salt for one teaspoon of onion salt

4. Homemade Onion Salt Using Onion Powder

If a processed ingredient is short in our storage, we can buy more of the ingredient or make our ingredient at home. With onion salt, it would be easy to do it because you only need simple ingredients that are already available in your kitchen. Here are two ways you can make onion salt.


  • One tablespoon of salt
  • One tablespoon of onion powder


  1. Take a mixing bowl and add salt and onion powder inside.
  2. Mix and put them all in an airtight container.
  3. Store the container in a cool and dark place.

If you don’t have onion powder in your kitchen, you can always use the fresh onions. However, it is better if you use dry ingredients such as dried onion flakes and dehydrated onions.

5. Homemade Onion Salt Using Chopped Onions

Here is how you can make a homemade onion salt recipe from chopped onions:


  • One medium-size onion
  • 2 ½ teaspoon of salt
  • ½ teaspoon of peppercorns


  1. Cut the onion to slices with ¼ inches thick.
  2. Put the slices on a dehydrating sheet and dry them at 125 degrees Fahrenheit for 6-8 hours. This would dry out all of their water content completely.
  3. Once they are dry, take out a coffee grinder or a spice grinder for grounding dry onion slices. Put the slices, salt, and peppercorns inside and grind them until you achieve a smooth texture. There can still be clumps after you have grounded them.
  4. Pour the mixture of onion into an airtight container and store it for a week. Then you can use it on your recipes.

If you love making homemade onion salt, you can actually make a large batch of dry onions and store them for months. Whenever you need to use onion salt, you just need to take them out and grind the mixture as instructed above.


1. How To Store Onion Salt?

For a home cook, storing food is as necessary as buying and making the food. When you store your ingredients properly, you will be able to reuse them for a long time without paying excessive money for new ingredients after one cooking section.

For storing onion salt, you can pour the mixture inside a glass jar or an airtight container. Then, store them in dark storage with cool temperatures, such as in the fridge. When stored properly, the onion salt can last up to three years.

2. What Goes With Onion Salt?

Onion salt is a seasoning ingredient so that it can go with many types of dishes and food. For example, you can give a great taste to vegetables like mild potato recipes.

You can sprinkle them on baking potato or mix into the sour cream for potato chips. Feel free to whisk it with mashed potatoes or potato soup.

Roasting meat can even taste better when you sprinkle some onion salt before putting them in the oven. You can combine this great ingredient with paprika and garlic powder when seasoning them.
