Onion Flakes Vs. Onion Powder – Quick Guide

Fresh onions are an essential ingredient in the kitchen, providing flavor and aroma to various aromatic combinations. Although fresh vegetables can’t always be replaced in cooking, there are plenty of recipes that benefit from the taste of onion but don’t require them to be freshly chopped. Stews, meatloaf, dressings, dips, and burgers are all perfect examples. Onion flakes or onion powder both offer delicious onion flavor and are super-convenient to use. There is no need for time-consuming chopping, and you can say goodbye to the onion tears!

A commonly asked question is what’s the difference between onion flakes and onion powder? Do they taste the same, offering similar levels of potency? Can they be used interchangeably in cooking? Let’s dive in and compare these two seasonings.

What is the difference between onion flakes and powder?

Onion flakes and onion powder are both seasonings used in cooking for adding onion flavor to food. Onion flakes are made by mincing fresh onions then dehydrating; onion powder takes fresh onions and dehydrates, air dries, or freeze-dries the vegetables before crushing into a powder. Whichever option you choose they both offer a subtle taste of onion and most brands use 100% onions with no additional ingredients added.

Key points

  • Both seasonings can usually be found in the spice aisle of the grocery store
  • They are a convenient, hassle-free replacement for fresh onions and are perfect as a lightweight option for camping.
  • Onion powder is ground finer than onion flakes and can be used in smaller quantities as it has a more potent flavor.
  • Both can be made from white, yellow, or red onions. Learn more about onion varieties here.


Onion flakes and onion powder can be used interchangeably; however, keep in mind that they have different levels of potency. To replace one teaspoon of onion powder use one tablespoon of onion flakes.

Onion flakes are sold in jars or bags containing small wispy pieces of onions that are easily re-hydrated once added to liquid. The consistency can vary from small bits through to larger chunks depending on the brand. Onion powder is also sold in jars or bags and can range from a fine to chunky powder.

Culinary uses

Onion flakes: During processing, onion flakes take on richer, sweeter, toastier flavor than fresh onions. Add them to casseroles, burgers, stews, soups, dips, eggs, and any other food that benefits from punchy onion taste. It is best to use the flakes in food that has moisture to help reconstitute the dried onions.

Onion powder: Use onion powder in much the same way that you would use onion flakes. They also work well as a seasoning sprinkled over pizza, chicken, and pasta. Onion flakes are ideal for use as a meat rub and are a primary ingredient in beau monde seasoning.

Keep in mind that flavor intensity and texture are the two factors that set onion flakes and powder apart. Onion powder carries a stronger flavor than flakes so if you’re looking to substitute one for the other, consider the quantities. Also, onion flakes will add texture to your food which may not always be ideal. For example, do you want to add chunky bits to your onion dip? If not, onion powder is your best option.


Storing onion flakes or onion powder properly will help extend their shelf life and keep their flavor and quality for longer. They should be stored in a cool, dark, dry place such as a pantry or cupboard. Never store seasonings near heat such as a conventional oven.

Try to avoid shaking onion powder or flakes into your food as steam from the pan can get into the container, causing the seasoning to clump and lose quality. Instead, shake the spice into a spoon away from the stove-top.

Summing up

Onion powder and flakes are both convenient options for adding onion flavor to food without the hassle of having to chop, slice, or dice. Although they’ll never replace fresh onions next time you make a mirepoix or sofrito, they can be kept in the spice rack for any recipe requiring a burst of onion flavor.

They are similar ingredients, both made from 100% fresh onions. The powder provides a stronger oniony taste and should be used in smaller doses than flakes.
