How Many Calories Are in 10 Chestnuts?

Despite their modest size, chestnuts are a surprisingly nutritious snack, especially when roasted. If you're munching on a handful—about 10 kernels, which weighs roughly 84 grams—you're consuming around 206 calories. That makes them a more calorie-dense nut than some might expect, but what sets chestnuts apart is their unique nutritional profile.

Unlike most other nuts, chestnuts are lower in fat and higher in carbohydrates, making them more similar to a starchy vegetable like a sweet potato than a typical nut. They’re also a decent source of fiber and provide a modest amount of protein—about 2.7 grams per serving. This makes them a satisfying option for sustained energy, particularly during colder months when they’re in season.

What’s more, chestnuts are rich in vitamin C—a rarity among nuts—which helps support immune function and skin health. They also contain potassium, magnesium, and antioxidants like gallic acid, which may help reduce inflammation.

Of course, how you prepare them matters. Roasted chestnuts, the classic street-food treat, are usually prepared with minimal added fat, keeping them relatively wholesome. But if they’re boiled in sugar water or cooked with butter, the calorie count and sugar content can climb quickly.

So, while 10 roasted chestnuts clock in at just over 200 calories, they offer more than just energy—they bring flavor, texture, and a host of micronutrients. Whether enjoyed on their own or tossed into salads and stuffings, chestnuts are a seasonal delight worth savoring.
