How Many Calories In Onion

When it comes to preparing healthy meals, onions are a go-to ingredient for adding flavor and nutrition. But how many calories are in an onion? The answer depends on the size of the onion and its type. Let’s break it down.

A typical medium-sized raw onion (about 110 grams) contains approximately 44 calories, making it a low-calorie option for enhancing your favorite dishes. Onions are also rich in nutrients, contributing essential vitamins, minerals, and antioxidants without adding significant calories. These versatile veggies are high in vitamin C, potassium, and dietary fiber, all while being naturally low in fat.

If you're looking at other sizes or types of onions, the calorie count can vary slightly. A small onion (about 70 grams) comes in at around 28 calories, while a larger onion (about 150 grams) contains approximately 60 calories. Red, white, and yellow onions have similar calorie counts, so the choice of type often comes down to flavor preferences or recipe requirements.

Whether you’re sautéing onions for a stir-fry, roasting them as a side dish, or incorporating them into salads and sandwiches, their low-calorie nature makes them an easy addition to any meal plan. Plus, the natural sugars in onions also caramelize beautifully, adding a touch of sweetness without the need for extra sauces or high-calorie seasonings.
