How Many Calories in an Onion?

Onions are a staple in many dishes around the world and are known for their distinct flavor and versatility in cooking. While they may not be the most calorie-dense food, it’s important to understand the nutritional value of onions if you’re trying to watch your caloric intake or maintain a healthy diet.

So, how many calories are in an onion? It depends on the size and type of onion you’re consuming. On average, a medium onion contains about 45-60 calories. This may vary slightly based on the specific variety of onion, as some types may be larger or smaller than others.

One medium onion is roughly equivalent to about 1 cup of chopped onions. If you’re consuming onions raw or adding them to a dish in smaller quantities, the calorie count will be lower.
