How many calories is in 1 cup of roasted broccoli?

Broccoli is a nutritious vegetable that is low in calories but high in vitamins, minerals, and fiber. Understanding the calorie content of roasted broccoli can help you make informed choices when building a healthy, balanced diet.

The Calorie Content of Roasted Broccoli

According to the USDA National Nutrient Database, 1 cup of chopped broccoli that has been roasted contains approximately 51 calories.

This is based on broccoli that has been roasted either in the oven or on the stovetop using a small amount of oil. Roasting brings out the natural sweetness of broccoli and caramelizes it slightly.

The calorie count may vary slightly depending on the exact preparation method, as well as how finely the broccoli is chopped after roasting.

Nutritional Breakdown of Roasted Broccoli

In addition to being low in calories, roasted broccoli is packed with beneficial nutrients:

  • Fiber – 2.4g per cup
  • Vitamin C – 70% DV
  • Vitamin K – 116% DV
  • Folate – 14% DV
  • Manganese – 7% DV
  • Potassium – 8% DV

The fiber, vitamins, and minerals in broccoli provide a range of health benefits. Fiber supports digestive and heart health. Vitamin C boosts immunity and promotes healthy skin. Vitamin K is important for blood clotting, and folate is critical for cell growth and DNA production.

In addition, broccoli contains beneficial plant compounds like sulforaphane and indoles, which have antioxidant and anti-cancer effects.

Comparing Roasted Broccoli to Raw

Roasting broccoli does result in some changes to its nutritional profile compared to eating it raw. Here is how the numbers compare:

Nutrient 1 Cup Raw Broccoli 1 Cup Roasted Broccoli
Calories 31 51
Fiber 2.4g 2.4g
Vitamin C 81% DV 70% DV
Vitamin K 92% DV 116% DV
Folate 11% DV 14% DV

As you can see, roasting slightly increases the calorie and vitamin K content of broccoli, while decreasing the vitamin C content. However, the differences are relatively minor.

Both raw and roasted broccoli are healthy, low-calorie options that provide important vitamins, minerals, fiber, and antioxidants.
