 In the world of cooking, onions are a staple ingredient, adding flavor, depth, and aroma to countless dishes. However, there are times when using fresh onions may not be practical or convenient. That’s where onion powder comes in as a versatile and flavorful substitute.

Onion powder is a dehydrated and ground form of onion commonly used as a seasoning in cooking. It has a strong, pungent flavor and aroma similar to fresh onions but is much more concentrated and has a longer shelf life. It’s better to know the right amount when using onion powder instead of onion because adding more powder can intensify the flavor and make the recipe bitter.

But how much onion powder do you need to replace one fresh onion? This guide will provide a comprehensive conversion table and detailed explanations of how much onion powder equals one onion to help you master the art of onion powder substitution. 

What is Onion Powder

As said above, onion powder is a finely ground seasoning made from dehydrated onions. It is a convenient and long-lasting way to add onion flavor to your dishes without the hassle of chopping and peeling fresh onions. Onion powder is concentrated, so a small amount can enhance the flavor of soups, stews, sauces, marinades, and even dry rubs. It is a key ingredient in seasoned salt and spice mixes, such as Old Bay seasoning and ranch dressing.

Onion powder is made by thinly slicing onions and then drying them in a low oven or dehydrator. The dried onions are then ground into a fine powder. Onion powder can be made from white, yellow, or red onions, but white onions are the most common type because they have a milder flavor.

How Much Onion Powder Equals One Onion?

The general rule of thumb is that 1 tablespoon of onion powder is equal to one medium onion. However, the exact amount of onion powder you will need will vary depending on the size and type of onion and the desired level of onion flavor. 

If you want a more intense onion flavor, use up to 1½ teaspoons of onion powder per medium onion. However, remember that too much onion powder can make your dish taste bitter.
