Tag: Cooked onion calories

A medium cooked onion, drained after boiling, contains only about 39 calories, making it an exceptionally low-calorie addition to meals. To determine exactly how many calories are in a whole cooked onion, one must consider factors like the onion's size and preparation method, which can greatly impact the overall nutritional value.

According to the USDA, a medium-sized raw onion (around 110 grams) contains approximately 44 calories, making it a very low-calorie ingredient. This low energy density is just one part of the picture when considering how many calories are in a white onion, as cooking methods can significantly alter the final count.
