Broccoli offers a modest amount of protein per serving while bringing fiber, vitamins, and low calories to your plate.
Does Broccoli Contain Protein? Nutritional Overview
Short answer: yes, broccoli does contain protein. It is not in the same league as meat, eggs, or legumes, yet every bite adds to your daily total. That matters when you eat broccoli often or pair it with other plant foods across the day.
Data taken from detailed nutrient tables for raw broccoli show that 100 grams provide about 2.8 grams of protein and only around 34 calories, along with water, fiber, and a long list of vitamins and minerals.
Cooked broccoli changes a little because water content shifts with heat. Once boiled or steamed and drained, USDA-based data for cooked broccoli show that 100 grams sit closer to 2.3 grams of protein, with calories still in the mid-30s. So the vegetable keeps its role as a light, nutrient-dense side dish that still brings a small protein boost.
How Much Protein You Get From Common Broccoli Portions
Most people do not weigh broccoli on a scale. You think in cups, florets, spears, or stems. To judge how much protein you actually get, it helps to translate the numbers from 100-gram charts into everyday servings.
Raw Broccoli Protein Per Cup Or Florets
One cup of chopped raw broccoli, roughly 90 to 95 grams, lands near 2.5 to 2.7 grams of protein. A single raw spear has less than a gram. A full stalk with leaves and florets can reach 4 grams or so, depending on size.
Those numbers may look small beside a chicken breast, yet the calories are tiny as well. That means you can pile broccoli high on the plate and gain fiber and micronutrients along with a little extra protein without blowing through your energy budget.
Cooked Broccoli Protein After Boiling Or Steaming
Cooking softens the stems, shrinks the florets, and makes the vegetable easier to eat in large portions. A half-cup of cooked, drained broccoli, about 80 to 90 grams, usually carries around 2 grams of protein.
Because cooked pieces pack more tightly into a cup, a full cup of cooked broccoli can climb to 3 to 4 grams of protein. If you eat a generous side portion at dinner, or toss a cup into a pasta dish or grain bowl, that serving quietly adds a few grams to your daily protein tally.
Table 1: Protein In Different Broccoli Forms And Servings
The table below pulls common serving sizes together so you can scan them at a glance.
| Broccoli Form | Approximate Serving Size | Protein (grams) |
|---|---|---|
| Raw, chopped | 100 g | 2.8 g |
| Raw, chopped | 1 cup (91 g) | 2.5–2.7 g |
| Raw, single spear | 31 g | 0.8 g |
| Cooked, boiled, drained | 100 g | 2.3–2.4 g |
| Cooked, boiled, drained | 1/2 cup | 2 g |
| Cooked, boiled, drained | 1 cup | 3–4 g |
| Frozen, cooked | 1 cup | 3–4 g |
How Broccoli Protein Fits Into Daily Needs
Nutritional agencies often describe protein needs in grams per kilogram of body weight. Advisory groups in Europe and global bodies tied to the United Nations widely use a baseline of about 0.8 grams of protein per kilogram of body weight per day for healthy adults. That equals roughly 54 grams of protein for a 150-pound person and around 65 grams for someone at 180 pounds.
Some people, such as older adults or strength athletes, may aim higher within a safe range, especially when they want to preserve or build muscle. Plant foods such as broccoli usually serve as one piece of the puzzle alongside beans, lentils, tofu, nuts, seeds, eggs, fish, or meat.
If you eat two full cups of cooked broccoli in a day, you might bring in 6 to 8 grams of protein from the vegetable alone. That covers only a slice of the daily target, yet it still counts, and it arrives packaged with fiber, vitamin C, vitamin K, folate, and potassium.
Take a sample day: breakfast with oats, yogurt, and a handful of nuts might land near 20 grams of protein; lunch with a bean salad, whole grains, and a side of broccoli could add another 25 grams; dinner with fish, tofu, or lean meat plus steamed broccoli often supplies the remaining grams with room to spare.
Broccoli And Protein Quality
Broccoli protein comes from many different amino acids. Like most vegetables, it does not provide all of the indispensable amino acids in the proportions found in animal foods. Even so, research on plant-forward eating patterns shows that when people combine a range of plant sources across the day, total protein and amino acid intake match or exceed baseline needs.
Dark green vegetables play a helpful role here because they tend to deliver more protein than lighter salad greens. Broccoli sits in that group along with Brussels sprouts, kale, and similar vegetables, which together nudge overall protein intake upward while keeping calorie density low.
Health Upsides Beyond Broccoli Protein
When you decide whether the protein in broccoli makes the vegetable worth your time, it helps to zoom out to the rest of the nutrient package. Broccoli brings substantial vitamin C, vitamin K, folate, carotenoids, and fiber. That mix ties in with better long-term cardiovascular and metabolic health when it shows up regularly on the plate.
Public health organizations that study diet patterns, including findings summarized in the healthy diet fact sheet from the World Health Organization, link higher intake of vegetables such as broccoli with lower risk of chronic disease. Guidance on healthy eating from leading schools of public health and global agencies consistently points people toward plant-rich plates that leave plenty of room for dark green vegetables.
Research groups that follow large cohorts often note that diets rich in broccoli and other cruciferous vegetables appear linked with lower inflammation markers and healthier body weight trends.
Broccoli also gives meals volume and texture. A bowl that includes broccoli along with a grain and a higher-protein item such as beans, fish, or tofu tends to feel more filling than the same ingredients without the vegetable. That can help appetite control and make balanced eating feel more satisfying.
Comparing Protein In Broccoli To Other Foods
To place broccoli protein in context, it helps to see how it stacks up next to other familiar foods. Animal products such as chicken, turkey, fish, and Greek yogurt have far more protein per serving. Plant foods such as lentils, chickpeas, tempeh, and firm tofu also deliver much more protein per cup than broccoli.
At the same time, broccoli can still bring value inside mixed meals. It fills space on the plate with minimal calories and adds a couple of grams of protein that pair well with denser sources. That mix makes it easier to reach daily protein needs without relying solely on meat or protein powders.

Use this table to scan how broccoli compares with several other foods that show up often in meals.
| Food | Typical Serving | Protein (grams) |
|---|---|---|
| Broccoli, cooked | 1 cup | 3–4 g |
| Chicken breast, cooked | 3 oz | 25–27 g |
| Firm tofu | 1/2 cup | 10–12 g |
| Lentils, cooked | 1 cup | 17–18 g |
| Greek yogurt, plain | 3/4 cup | 15–17 g |
| Almonds | 1 oz (about 23 nuts) | 6 g |
Ways To Add More Broccoli Protein To Your Day
Since each serving carries only a few grams of protein, the trick is to eat broccoli often and pair it with other protein-rich foods. Small changes across meals can move the needle.
Boosting Breakfast, Lunch, And Dinner
At breakfast, you might toss leftover roasted broccoli into an egg scramble or fold it into a savory oatmeal bowl with cheese and seeds. For lunch, chopped raw florets can bulk up a grain salad with chickpeas, quinoa, or canned tuna. At dinner, broccoli works in stir-fries, pasta dishes, sheet-pan meals with salmon or tofu, and hearty soups.
When you repeat those small additions, you can easily reach two or more cups of broccoli over the day. That habit might add 6 to 10 grams of protein plus fiber and micronutrients without asking you to chew through large amounts of meat.
Pairing Broccoli With Other Plant Proteins
Broccoli pairs well with beans, lentils, tempeh, and tofu in grain bowls, curries, and casseroles. Combining those ingredients means your plate delivers both quantity and quality of protein while staying rich in fiber and micronutrients.
Sprinkling nuts or seeds over cooked broccoli also raises the protein content of the dish. Slivered almonds, toasted pumpkin seeds, or sesame seeds bring crunch, healthy fats, and several extra grams of protein, all in a small handful.
Is Broccoli A Good Protein Source On Its Own?
On its own, broccoli does not compete with classic protein foods. You would need to eat very large portions to cover your entire daily requirement from this vegetable alone. That would be hard for most people and would crowd out other helpful foods.
Broccoli works best as a steady background player. When you place it next to higher-protein items at several meals, its contribution becomes meaningful over the full day. The vegetable helps you eat more plants, trim excess calories, and still nudge your protein intake upward.
Anyone with kidney disease, diabetes, or other medical conditions should work with a qualified health professional on overall protein targets, including how much to rely on plant sources such as broccoli versus animal foods.
So if you enjoy the taste and texture, treat broccoli as a reliable sidekick rather than the star of your protein plan. Use it often, heap it generously on the plate, and let it do quiet work in the background while beans, lentils, tofu, fish, eggs, or meat carry the heavier load.
