Top 10 Substitutes
Don’t have onion powder to hand? No problem! Here are some of the best onion powder substitutes to use:
Fresh Onion
Onion powder is literally just dehydrated onions ground into powder, so fresh onion is often the next best alternative for onion powder.
However, there are several factors to keep in mind when using fresh ones as a substitute for powdered.
Onion powder is much more concentrated in terms of flavor, so you’ll have to use a lot more of the fresh stuff for it to adequately substitute for the powdered version. This means that for every teaspoon required in the recipe, you’ll have to substitute it with three tablespoons of freshly chopped onion.
Furthermore, fresh onion contains 86% water, while the powdered variety contains near zero. If the recipe specifically calls for onion powder, like in fried chicken, for example, fresh onion might not work unless you mince it finely.
You’ll also have to dry the onion out as much as possible before adding it to the dish so as to not impact the liquid content of the recipe. If you don’t, the onions might turn mushy and ruin your dish.
Recipes using fresh onions: Beef and Kale Soup, Hash brown Quiche Cups or Tomato Cucumber Onion Salad.
Onion Flakes
Onion flakes are another fantastic alternative to onion powder, as onion flakes are dehydrated onions that haven’t been ground fine. You can use the flakes as is or grind them with a mortar and pestle.
If you’re planning to use the flakes as is, use a 2:1 flakes-to-powder ratio. So, for every teaspoon required in the dish, substitute it with two teaspoons of onion flakes.
If you’re grinding the flakes into powder, it is just a simple 1:1 substitute.
Recipes using Onion Flakes: Slow Cooker BBQ Chicken, Black Bean Taco Stuffed Sweet Potatoes and Air Fryer Sweet Asian Chili Wings.
Minced Onion
In terms of texture, minced onion falls in between onion flakes and onion powder. It isn’t as coarse as the flakes, but it isn’t as fine as the powder.
It is made by dehydrating pre-minced onion. So, if a recipe calls for a cup of fresh onions, you can easily rehydrate them by soaking about three tablespoons of minced onions with three tablespoons of boiling hot water.
To replace onion powder with minced onion, use a 2:1 substitute. For every teaspoon of onion powder required, use two teaspoons of minced onion.

Onion Salt
Onion salt is another excellent substitute that packs just as much flavor as onion powder.
It is simply onion powder that has salt added to it, making it a near-perfect substitute. It’s great for fried chicken, soups, marinades, stews, tomato dishes, and a bunch of other recipes.
On average, onion salt has about 450 milligrams of sodium as opposed to 575 milligrams in the same size serving of table salt. As such, you’ll have to reduce the salt content in your dish when using it.
To substitute onion salt with onion powder, use a 1:1 measurement and adjust the salt in your dish accordingly.
Recipes to use Onion Salt: Air Fryer Chicken Livers, Air Fryer Jerk Chicken, Air Fryer Hush Puppies
Onion Paste
Onion paste is usually my go-to alternative for onion powder because it packs a lot of flavors and adds a bit of freshness to the dish.
Onion paste is made by pureeing fresh onion until it turns into a smooth paste. It’s then stored in the fridge. Some people add cloves, black peppercorns, cinnamon, salt, and other seasonings to further enhance the onion flavor.
Use a 2:1 substitute when using onion paste in place of onion powder. This means for every teaspoon of onion powder required, use two teaspoons of onion paste. You’ll also have to reduce the liquid content of your dish just slightly.
If you’re using pre-seasoned onion paste, make sure to reduce the overall seasoning in your dish so as to not overpower the flavor.
Recipes to use Onion Paste: Smoked Chicken Thighs, Smoked Chuck Roast, Grilled Sausage Breakfast Casserole.
Garlic Powder
Garlic powder tastes different than onion powder, but it is close and won’t compromise the overall flavor profile of the final dish.
Moreover, they share the same texture, making garlic powder an easy substitute.
Since garlic powder is slightly more robust in flavor, use half a teaspoon for every teaspoon of onion powder required, and gradually increase to your taste.
Recipes to use Garlic Powder: Jamaican Swordfish, Lamb Chops, Smoked Turkey Breast.
Garlic Salt
Just like onion salt, garlic salt is a mixture of garlic powder and salt. It’s not as fine as the powders, but it still makes for a great substitute in most recipes; particularly in casseroles, pastas, soups, and stocks.
Garlic salt contains about 320 milligrams of sodium per quarter of a teaspoon, which is almost three times the amount found in onion salt. As such, if you’re planning to use garlic salt, adjust the other salt in your dish.
Use half a teaspoon for every teaspoon of onion powder—and take note of the salt content it’ll add to the dish.
If you’re following a specific diet that requires you to cut back on sodium, it’s best to skip this alternative. The same goes for onion salt; replace it with a different substitute from this list.

Fennel Bulb
Fennel bulb is just as flavorful and aromatic as onions, so it’s not surprising that you can use it in lieu of onion powder.
It has a bit of anise-like taste to it, which might turn off some people, but as long as you use it sparingly until you know you like it, it will be just fine!
Fennel bulb is also a great way to add a bit of texture to your recipe, which is particularly welcome in stews, meat dishes, and selected soups.
When using fennel bulbs as a substitute, follow the same instructions as fresh onions. Fennel bulbs have more or less the same amount of water, so you’ll have to dehydrate or dry the bulbs as much as you can before using them. If you want to skip the dehydration process and get straight to cooking, you might need to reduce the water content of your dish.
Celery Stalk
Celery adds a welcome aromatic flavor to your dish. It doesn’t taste as pungent as onion powder, so you might want to increase the vegetables or seasonings of the recipe to achieve a more layered and complex flavor. You can never go wrong with more veggies, right?
If you’re using it in a stew, reduce the liquid to compensate for the high moisture content.
For every teaspoon of onion powder required, use about three to four tablespoons of finely chopped celery.
Celery Seed
Celery seed adds a similar note to a dish without greatly compromising the texture or flavor. You can use the seeds “as is”, or you can use a mortar and pestle to grind them into a powder.
As you might expect, celery seeds taste a lot like celery. It has a savory, earthy, and slightly bitter flavor that’s amplified when used in powdered form.
Use a 2:1 substitute when using whole celery seeds, or a 1:1 substitute when using ground celery seeds.
How to Make it from Scratch at Home
Nothing can truly replace the taste and texture of onion powder, so if you have a bit of time in your hands, consider making onion powder from scratch. It’s cheap, safe, and tastes significantly better than store-bought versions.
Here’s how to make it:
- Peel the onion and chop it as small as you can.
- If you have a dehydrator, place the chopped onions inside and let them dry for about 3 to 9 hours at 125˚F. If you don’t have one, spread the chopped onions on a baking sheet and place them in the oven for one to three hours at 150˚F. You’ll know the onions are ready when they crumble easily in your hands.
- Remove the onions from the dehydrator/oven and let them cool for about 15 minutes.
- Transfer the dried onions into a spice mill, a food processor, or a coffee grinder and grind them up into a powdered form. You can also use a mortar and pestle if you don’t have the other options available.
- Store the freshly-made onion powder in an air-tight container and place it in a cool, dry place.
