The Average Weight of a Single Broccoli Stalk
The most widely cited average for a single, raw broccoli stalk, based on data from sources like the USDA, is 114 grams, or about 4 ounces. This measurement represents a typical portion, but it's important to understand that this is an average, and the actual weight of the produce you find at a supermarket can differ. A single head of broccoli, which consists of the florets and the attached stalks, typically weighs between 300 and 500 grams, or approximately 9 to 18 ounces, depending on its size. For more precise calorie counting or recipe formulation, relying on a scale is the most accurate method.
Factors Influencing Broccoli Stalk Weight
Several elements beyond just the visible size can contribute to the weight of a broccoli stalk.
Variety and Cultivation
Different varieties of broccoli are cultivated to produce varying characteristics, including yield and head size. Research has shown that certain varieties and specific cultivation methods, such as the use of organic fertilizers, can lead to different crop weights and head sizes. The thickness and sturdiness of the central stem, which makes up a large portion of the stalk's weight, can also be influenced by the growing environment.
Growing Conditions
Environmental factors play a significant role in a plant's growth. Optimal conditions, including adequate moisture and balanced nutrients in the soil, will produce healthier and heavier plants. For example, the use of certain organic or inorganic fertilizers at specific doses can directly impact the wet weight of the broccoli crop. Temperature is another critical factor; studies have shown warmer temperatures during the later stages of growth can result in heavier heads and thicker stems.
The Whole Head vs. The Trimmed Stalk
When people refer to a 'stalk' of broccoli, they are sometimes thinking of the whole head, which includes the florets, while others mean just the thick, central stem. The weight of the stalk alone is considerably less than the weight of the entire head. A 9-ounce medium head of broccoli can contain several individual stalks and florets, with the trimmed stalk being a significant but not majority portion of the total weight. A typical head contains a main central stalk from which smaller spears and florets branch off.
Measuring Broccoli for Recipes and Nutrition
For culinary and nutritional accuracy, measuring vegetables by weight is almost always superior to measuring by volume. Volume measurements, such as using a measuring cup for chopped broccoli, are inherently inconsistent due to how tightly or loosely the pieces are packed. A digital kitchen scale provides the most reliable data for portioning ingredients, whether you're counting calories or following a recipe precisely.
A Comparison of Broccoli Weights
| Item | Average Weight (grams) | Average Weight (ounces) |
|---|---|---|
| 1 raw stalk (USDA) | 114 g | 4 oz |
| 1 raw spear (5” long) | ~31 g | 1.1 oz |
| 1 raw floret | ~11 g | <1 oz |
| 1 cup chopped broccoli | ~91 g | 3.2 oz |
| 1 medium head (approx.) | ~255 g | 9 oz |
Practical Tips for Using Broccoli Stalks
Contrary to popular belief, the stalk of the broccoli plant is completely edible and quite nutritious. It is rich in fiber and has a slightly sweeter, milder flavor than the florets. Here are some ideas for incorporating it into your cooking:
- Slicing and Stir-Frying: Peel the outer, tougher layer of the stalk and slice the tender inner part into thin coins or matchsticks. They cook up quickly and add a great texture to stir-fries.
- Salads and Slaws: Grate the peeled stalk and add it raw to salads for extra crunch. It makes a fantastic, low-carb base for a coleslaw.
- Pureed Soups: Dice the stalks and add them to soups or sauces to create a thicker consistency. The stalk will soften beautifully when cooked down.
- Roasted Vegetables: Cut the stalks into bite-sized chunks and roast them along with your florets. They will caramelize and become sweet and tender.

Conclusion
While an average figure of 114 grams or 4 ounces provides a useful baseline for one raw stalk, the actual weight of the broccoli you purchase will vary. To ensure accuracy for both recipes and nutrition tracking, relying on a kitchen scale is the most dependable approach. Furthermore, remember that the stalk is a nutritious and versatile part of the plant that should not be overlooked in your culinary creations. By utilizing both the florets and the stalks, you can maximize your vegetable's nutritional value and reduce food waste.
