The Calorie Breakdown of Rocket Leaves
For anyone counting calories, rocket leaves are an excellent choice due to their incredibly low energy density. A standard 100-gram serving of raw rocket contains just 25 calories. To put this into perspective, you would need to eat a very large amount of rocket to significantly impact your daily caloric intake. The minimal energy comes from its macronutrient composition, which is primarily carbohydrates and protein, with very little fat. This high water content is a key reason for its low-calorie status, as water contains zero calories and helps to add volume to your meals without the added energy.
When looking at the macronutrient breakdown for 100g of raw rocket leaves, the numbers are as follows:
- Carbohydrates: Approximately 3.7 grams
- Protein: Approximately 2.6 grams
- Fat: Approximately 0.7 grams
- Fiber: Approximately 1.6 grams
This distribution highlights why rocket leaves are a smart choice for maintaining a healthy weight. The combination of low calories and low fat, coupled with a good amount of fiber, helps promote satiety and prevent overeating. Furthermore, eating the leaves raw, as they are typically consumed, ensures you get the full nutritional benefit, as cooking can sometimes degrade sensitive vitamins.
Beyond Calories: A Nutritional Powerhouse
Rocket leaves are far more than just a low-calorie food; they are packed with a wide array of vitamins and minerals. The nutritional content of 100g of raw rocket provides significant percentages of the recommended daily intake for several key micronutrients:
- Vitamin K: Essential for bone health and blood clotting. Rocket is an excellent source of this nutrient.
- Vitamin C: A powerful antioxidant that boosts the immune system and aids in collagen production.
- Vitamin A: Important for vision, immune function, and cellular growth, often present as beta-carotene.
- Folate (Vitamin B9): Crucial for cell growth and metabolism, particularly important during pregnancy.
- Calcium: A mineral vital for strong bones and teeth.
- Potassium: Helps regulate blood pressure and fluid balance.
- Magnesium: Involved in hundreds of bodily processes, including muscle and nerve function.
In addition to these vitamins and minerals, rocket leaves also contain phytochemicals, such as glucosinolates, flavonoids, and carotenoids. These compounds are responsible for some of the vegetable's health-protective properties, including antioxidant and anti-inflammatory effects.

How to Cook and Serve Rocket Leaves
Preparing Raw Rocket for Salads
To prepare raw rocket for salads, start by washing the leaves thoroughly under cool water to remove any dirt or grit. Pat them dry gently with a paper towel or use a salad spinner to prevent sogginess. For a simple and delicious salad, toss the rocket with a light vinaigrette, some cherry tomatoes, and a sprinkle of parmesan cheese. The bitterness of the rocket balances the sweetness of the tomatoes and the saltiness of the cheese perfectly.

Because of its distinct, peppery flavor, rocket pairs well with ingredients that can either complement or contrast it. It goes exceptionally well with sweet and savory flavors alike. Consider adding it to a salad with sliced pears, walnuts, and a blue cheese dressing. For a savory application, serve it alongside roasted chicken or fish, drizzled with a balsamic glaze. Its versatility is what makes it a chef's favorite ingredient for adding a burst of flavor to many dishes.
