I live in Europe but use many US recipes. These often call for onion powder which is hard to find here. Diced or minced onion is often not a good alternative and whilst garlic powder is easier to obtain, I find it complements rather than replaces onion powder. What could I use as (an easy to obtain) substitute for onion powder?

    It won't work if the recipe actually needs onion powder (because it's dry and concentrated) but if it's just for lazy seasoning you could just saute some finely minced onion and get it thoroughly browned.

    I'm in the UK. I never see onion powder in the shops, but it's not hard to find on the internet. Google is your friend...

    In the UK Tesco sell it. Also the Asian markets usually stock it.

Well, you could make your own onion powder. It isn't that difficult.

  1. Peel and finely chop your onions.

  2. Then, spread the onion pieces out on a tray and heat in a 150°F degree oven or in a food dehydrator until dry.

Tip: The onions are dry when you can easily crumble the chopped pieces in your hand.

  1. Allow the onions to cool. Then, grind with a coffee grinder, spice mill, food processor or mortar and pestle until you reach your desired consistency.

  2. Store your finished onion powder in an air-tight container in a cool, dry spot or freeze.

  • Oven temperature of 150 °C or °F?
