The Protein in Cooked Broccoli: A Detailed Look
For those tracking macronutrients or following a plant-based diet, understanding the protein content of various foods is crucial. While not a primary protein source like meat or legumes, broccoli is a surprisingly good contributor for a non-starchy vegetable. The amount of protein in 1 cup of cooked broccoli can vary slightly depending on how it's prepared, primarily due to changes in moisture content.
A cup of chopped, boiled, and drained broccoli contains about 1.9 grams of protein. This is a standard measure, representing a common cooking method. Interestingly, a cup of chopped raw broccoli has a slightly higher protein content at roughly 2.6 grams, because its water content hasn't been reduced through boiling. For frozen, chopped, and cooked broccoli, the protein content can be significantly higher—around 5.7 grams per cup. This is not because the broccoli gained protein, but because the freezing and cooking process concentrates the nutrients in a smaller volume by removing more water.
How Cooking Affects Nutrient Concentration
When you boil broccoli, the vegetable absorbs some water and loses some water-soluble vitamins, such as Vitamin C, into the cooking water. However, the protein itself is not destroyed by heat. In fact, some cooking methods, like steaming or roasting, can result in a more nutrient-dense product per cup because less water is retained. This concentration effect is most pronounced in frozen vegetables, where a higher degree of water loss occurs during processing and cooking, leading to a denser, more protein-packed serving by volume. Steaming is often recommended as a gentle way to cook broccoli to preserve more of its heat-sensitive nutrients.
More Than Just Protein: Broccoli's Complete Nutritional Profile
Broccoli's reputation as a "superfood" is well-deserved, and its benefits extend far beyond its protein content. It is a nutritional powerhouse packed with a wide array of vitamins, minerals, and bioactive compounds essential for health. Here's a quick look at some of the other key nutrients you get from a cup of cooked broccoli:
- Vitamin C: A single serving can provide a significant portion of your daily vitamin C needs, supporting immune function and skin health.
- Vitamin K: Crucial for bone health and proper blood clotting.
- Folate (Vitamin B9): An important nutrient for cell growth and metabolism.
- Fiber: Aids digestion, promotes gut health, and helps you feel full longer.
- Antioxidants: Contains powerful antioxidants like sulforaphane, which helps combat oxidative stress and inflammation.
- Minerals: A good source of potassium, magnesium, and iron.
Comparative Protein Content: Broccoli vs. Other Vegetables
To put broccoli's protein content into perspective, let's compare it to a few other common vegetables. This helps illustrate its role in a varied plant-based diet, where different vegetables contribute protein in varying amounts.
| Vegetable (per 1 cup cooked) | Protein (approx. grams) |
|---|---|
| Broccoli (boiled) | ~1.9g |
| Broccoli (frozen, cooked) | ~5.7g |
| Spinach (cooked) | ~5.3g |
| Green Peas | ~8.6g |
| Edamame (shelled) | ~18.5g |
As the table shows, while broccoli contributes protein, it is not on par with legumes like edamame or green peas. This emphasizes the importance of eating a variety of plant-based foods to meet daily protein goals. Combining broccoli with legumes or nuts creates a more complete protein meal. For example, pairing roasted broccoli with lentils or a handful of almonds dramatically increases the overall protein content of your meal.
Incorporating Cooked Broccoli into Your Diet
There are countless delicious ways to enjoy cooked broccoli and integrate it into your meals. Here are some ideas:
- Roasted Broccoli: Toss florets with olive oil, garlic powder, salt, and pepper and roast until tender-crisp. You can add a sprinkle of parmesan cheese for extra flavor and protein.
- Stir-fries: Add steamed or blanched broccoli to your favorite stir-fry. It pairs well with tofu or chicken for a complete protein meal.
- Soups and Salads: Cooked broccoli florets are a great addition to soups, like a hearty chicken and vegetable soup, or a chilled broccoli salad with a creamy dressing.
- Pasta Dishes: Mix cooked broccoli into your pasta with a light sauce and grilled chicken or chickpeas.

Conclusion: Broccoli's Place in a Balanced Diet
In summary, 1 cup of cooked broccoli provides a modest but beneficial amount of protein, typically ranging from 1.9 to 2.4 grams depending on the cooking method. While it should not be relied upon as a primary protein source, it is a valuable contributor to your daily intake, especially when paired with other plant-based protein sources like legumes and nuts. Broccoli's true strength lies in its comprehensive nutritional profile, offering high levels of vitamins C and K, fiber, and potent antioxidants. By including cooked broccoli in your meals, you are adding a low-calorie, nutrient-dense ingredient that supports overall health, immune function, and digestive wellness.
