What is onion powder?

Onion powder is a potent spice made from onions that have been either dehydrated, air dried or freeze dried, then ground into a fine powder. Onion powder typically has a sharp smell with just a hint of sweetness similar to that of fresh onions.

Uses of onion powder

Onion powder has many uses including:

  • It is used in many savory recipes as a way to enhance the flavor.
  • Used to season seafoods, meats, vegetables, casseroles, soups, stews, eggs
  • Use to add to dressings, sauces, marinades, vinaigrettes

So, if you’re in the middle of making a recipe and you’ve just realized that you have no onion powder on hand, the best onion powder substitute I’ve used are fresh onions, onion flakes, minced onions, onion juice, shallots, garlic powder, celery seeds and celery salt just to name a few.

I go into the details of each of these below.


10 easy ways to substitute for onion powder

Dehydrated minced onions

One of the best substitutes for onion powder is minced onions. Made by mincing, then dehydrating fresh onions, minced onions are just as flavorful as onion powder.

It can be used to replace powdered onion in recipes such as beef stew, gumbo, salad dressings, dips, dry rubs, burgers, roast meats and just about any other recipe that would call for onion powder.

In sauces, you may come across some pieces of the minced onions that are harder to dissolve.

Or, you can simply use a coffee grinder or food processor to grind the minced onions into a powder form and use in equal amounts.

Substitution ratio: 1 tablespoon onion powder = 1 tablespoon minced onions


Dehydrated onion flakes

Onion flakes are another great way to replace onion powder in cooking. Onion flakes are coarsely chopped fresh onion that have been dehydrated to form flakes.

Onion flakes have less potency than you would find in onion powder, but, in a pinch it can be used as a substitute on a 1:3 ratio.

Substitution ratio: 1 teaspoon onion powder = 3 teaspoon onion flakes


Fresh onions

Fresh onions are a great onion powder alternative in certain dishes. While onion powder has more concentrated flavors than fresh onions, they can definitely work in a crunch for recipes like certain sauces, soups, stews or chowders.

Note that onions have lots of water, in fact they are 89% water, so you will likely need to adjust the other liquids in your recipe to reflect that extra water.

Also, fresh onions will add more substance and texture to the recipe that the onion powder would not have, so keep that in mind as well.  

Substitution ratio: 1 tablespoon onion powder = 1/2 medium chopped onion


Onion juice

Can’t find onion powder? Why not try out onion juice as a replacement? Onion juice is the juice extracted from fresh onions. You can buy onion juice to replace both onion powder or fresh onions easily. 

Onion juice can be used to enhance the flavors of many recipes including marinades, soups, stews, salads, sauces, meats and so much more. 

However, because it is a liquid, onion juice cannot be used in seasoning mixes.

Also, because it is a liquid, it can add more moisture to certain recipes so use and make adjustments to reflect that extra liquid added to the original recipe from the onion juice.

Substitution ratio: 1 tablespoon onion powder = 1/2 teaspoon onion juice 


Onion salt

Onion salt is a mixture of table salt and onion powder sold in many retail stores. Typically the ratio of table-salt to onion powder is roughly about 3:1.

This means that there is less onion powder found in onion salt and so you must make the adjustments to your recipe with this in mind. This may mean cutting back on the other sources of salt in the recipe.

Besides the salt, onion salt has 3 times less onion powder than 1 tablespoon of plain onion powder.

So, it is important to recognize that the flavor of onion may not be as strong as you may expect when using onion salt vs onion powder.

This ingredient is best used to replace onion powder in marinades, dips and dry rubs. 

Substitution ratio: 1 tablespoon onion powder = 1 tablespoon onion salt


Garlic powder

Can I substitute onion powder for garlic powder? Yes you can! While each of these powders has a different flavor profile, it is possible to substitute one for the other in some recipes such as soups, stocks, stews and other such recipes.

Especially since naturally, the flavor of onion powder does have hints of garlic. 

Substitution ratio: 1 tablespoon onion powder = 1/2 tablespoon garlic powder



If you’re looking to impart a bit of onion flavor to a dish, chives are a great way to do so. They’re a member of the onion family and work well to substitute onion powder or onions in dishes like stir fries, added to vegetables, added to eggs, used to make creamy pasta sauces or simply as a garnish for soups.

While chives have somewhat of a milder oniony flavor, in a pinch they can be used as a worthy substitute. 

Substitution ratio: 1 tablespoon onion powder = 1/2 cup finely minced chives



Chives and leeks have very similar flavors. Therefore, in a pinch, you can also use leeks as a substitute for onion powder. 

Leeks are related to garlic, chives, shallots, and onions and have a sweet, oniony flavor.

So, if you ran out of onion powder, and the recipe will not be altered too much with the added texture or added bulk from the leeks, then finely mince up some leeks and add it to your dish for that sweet pungent onion like flavoring.

Some recipes in which leeks can replace onion powder include soups, stews, casserole dishes, eggs, stir fries and more.

Substitution ratio: 1 tablespoon onion powder = 1/2 cup finely minced leeks



alternatives for onion powder

Shallots can also act as a great alternative to onion powder. They have a mid onion like flavor that can be used in dressings, stews, soups, stir-fries, sautés and even marinades.

Substitution ratio: 1 tablespoon onion powder = 1/2 cup chopped shallots


Green onions

Another great substitute for onion powder are fresh minced green onions. They can both be used to add onion flavor to food.

Green onions can be used in recipes where some extra texture and bulk is not an issue like omelettes, dips, stews, soups, stir fried vegetables, meat dishes etc.

Substitution ratio: 1 tablespoon onion powder = 1/2 cup finely minced green onions
