how many calories are in green beans

A typical serving of plain green beans is quite low in calories: about 30–35 calories per 100 grams (3.5 oz) , or roughly 30–40 calories per cup cooked.

Quick Scoop

• 100 g raw green beans: about 31 calories.

• 100 g cooked (boiled, drained, no salt): about 35 calories.

• Roughly 1 cup cooked: usually lands in the 30–40 calorie range, depending on how tightly it’s packed and exact variety.

In everyday terms, a good mental estimate is “around 30 calories per 100 g,” which makes green beans a very low‑calorie side, especially compared with heavier sides like potatoes or creamy casseroles.

Small example

If you have a 150 g portion of plain steamed green beans (about a generous cup), you’re looking at roughly:

• 150 g × ~31–35 calories per 100 g ≈ 45–55 calories total.
