About onion powder
Onion powder is a dehydrated and finely ground spice made from dried onions, delivering a concentrated savoury flavour without the moisture or texture of fresh onions. It is a pantry staple used to season spice rubs, marinades, soups, sauces, and baked goods where a smooth, consistent onion flavour is desired. Its fine texture allows it to blend seamlessly into dry mixes and coatings, making it particularly useful in applications where raw onion would be unsuitable.
Best substitute
Dehydrated onion flakes are essentially the same product as onion powder but in a coarser form. They rehydrate well in moist dishes but should be ground in a spice grinder or mortar and pestle if a smooth texture is needed.
Alternative
Finely minced or grated fresh onion can replicate the flavour of onion powder but adds significant moisture and texture. It works best in cooked dishes, sauces, and marinades where the liquid content can be absorbed.

Garlic powder shares a similar pungent, allium character to onion powder and can stand in when onion powder is unavailable. The flavour profile is distinctly different — sharper and more intense — so use a smaller amount and expect a different but complementary result.
Alternative
Shallot powder is made from dehydrated shallots and offers a subtler, slightly sweeter allium flavour that is very close to onion powder. It can be used as a direct one-to-one swap and works well in delicate sauces and seasoning blends.
Alternative
Leek powder is a less common but effective substitute, offering a mild, slightly sweet onion-like flavour. It works well in soups, stocks, and seasoning blends where a gentler allium presence is acceptable.
