Whether pasta, curry or soup – onions are an indispensable ingredient in a variety of recipes. The quantities given usually refer to half an onion, a whole onion, etc., but they can easily be replaced by onion powder. Especially for people with intolerances, it is worth trying out the powder.

Of course, the products from different manufacturers differ. To help you find the right onion powder for you, we have compared several suppliers and listed the most important criteria that you should consider when buying.


  • Onion powder consists of dried onions and can be used excellently as an onion substitute in the kitchen. It is particularly suitable for people with intolerances or allergies, as the onions are powdered.
  • There are various suppliers of onion powder, the most important criteria for purchase are the quantity, the ingredients, the grain size and also the origin of the onions used.
  • The only difference between onion powder and onion granules is that onion powder is ground finer than onion granules. With the powdered variety, care should therefore be taken that no lumps form during cooking.

Buying and evaluation criteria for onion powder

You are still unsure which onion powder is best suited for your purposes? We have compiled the decisive criteria for you so that you don’t make a mistake:

In the following, we will take a detailed look at these aspects to help you make the best possible decision.


You can buy onion powder in different quantities, from 50 grams to a kilo. The right packaging size for you depends on how often you use the powder and in what quantities.

It is also good to know that onion powder will keep for about a year as long as it is stored in a dry, light-protected and airtight place – for example, in a spice tin. So if you are thinking about buying a larger quantity, there is no time pressure.


Onions contain a lot of different minerals and trace elements, which are not lost during the drying process, but are even present in increased form in the onion powder. These are potassium, manganese, calcium and phosphorus.

In addition, almost all vitamins are present (with the exception of vitamin B12, A and E). However, onion powder is also richer in carbohydrates than fresh onions. This is because all the liquid is removed from the onion in the drying process.


Onion powder is not always coarsely or finely ground. The degree of granulation depends entirely on the different manufacturers. Again, it depends on what you intend to do with your powder. For example, some manufacturers make sure that the onion powder is not too fine so that it does not clump together when added to sauces.


Often the onions are both grown in Germany and processed into powder. However, it is also worth taking a look at the organic seal. If this is present, you also have the guarantee that the product comes from controlled organic cultivation and is free of additives.

Guide: Frequently asked questions about onion powder answered in detail

In the following you will find a summary of frequently asked questions about onion powder.

What is onion powder?

Onion powder is produced when the moisture is removed from onions in a drying process (for example, using a dehydrator). The flavour remains largely unchanged, the dried version just has a slightly sweeter note. This is why it is an excellent substitute for fresh onions in all recipes.

Who is onion powder suitable for?

Many people have an intolerance or even an allergy to onions. If you also belong to this group of people, but still don’t want to miss out on the spice of onions, onion powder may be the solution for you.

Since the body reacts allergically to large pieces of onion, it is often the case that the reaction is much weaker or non-existent with onion powder.

The powder will also be a great help to those who regularly get teary-eyed when chopping onions in the kitchen.

What is the difference between onion powder and onion granules?

Onion powder and onion granulate are often used colloquially as synonyms, but this is not entirely correct. Granules and powder are nevertheless very similar, because both types of processing involve dried onions – onion granules are just not as finely ground as onion powder. They can therefore be used identically in cooking.

How is onion powder dosed?

When using onion powder, you should always remember that you are using onions in granulated or powdered form. As onion powder is therefore much more flavour-intensive than fresh onions, you should feel your way through the dosage at first. As a rule of thumb, however, you can remember that one tablespoon of onion powder is roughly equivalent to one medium-sized onion.


So you see, onion powder is a wonderful substitute for those who cannot or do not want to use fresh onions. Once you have found the right powder and the perfect dosage for you, you can always use it for cooking as well as for seasoning cold dishes.

Of course, fresh ingredients are the best option if possible, but the powder can also be beneficial from a health point of view, as the proportion of vitamins and trace elements is higher in onion powder and granulated onions. Not to be neglected, of course, is the time saving offered by the compressed variant.
