One cup of chopped raw broccoli has about 31 calories and 2.6 g of protein.
Broccoli gets talked about as a “free food,” then someone logs it and gets surprised by the entry they picked. It’s not mystery, it’s math. Calories and protein shift with weight, cooking, and what counts as a “cup.” Once you lock those down, the numbers stop bouncing around.
This article gives you practical serving conversions, shows where most broccoli calories come from, and helps you use broccoli’s protein in real meals without turning your plate into a chore.
What You’re Measuring When You Count Broccoli
“Broccoli” can mean a tight head with thick stems, a bag of florets, or a frozen mix. Each one has a different water content and different packing density in a measuring cup. That’s why two “cups” can land far apart on a tracker.
Weight beats volume for clean tracking
If you can, weigh broccoli in grams. Nutrition databases report values per 100 g, so your log stays consistent across raw, steamed, and roasted. A food scale also removes the “how hard did I pack the cup” problem.
Cooking changes weight more than it changes nutrients
Broccoli starts out water-rich. Cooking can drive off water, and draining can remove some water that clings to the florets. When water changes, weight changes, so calories per cup can swing even if calories per 100 g stay close.
Why “raw” and “cooked” entries look different
Databases often list separate items for raw broccoli and boiled, drained broccoli. You’ll see small differences in calories and protein per 100 g. The bigger day-to-day difference comes from your portion size and the cooking method you used.
Calories In Broccoli Come From Carbs With A Dash Of Protein
Broccoli is low in calories because it’s mostly water and fiber-rich carbohydrate. The rest is a small amount of protein plus traces of fat. That mix is why you can eat a big bowl and still land in a modest calorie range.
Raw broccoli calories, per 100 g
USDA FoodData Central lists raw broccoli at 34 calories per 100 g, with 2.82 g of protein in that same 100 g portion. Those numbers are the anchor for any serving conversion you do at home.
Cooked broccoli calories, per 100 g
For broccoli that’s cooked and drained, FoodData Central shows a similar calorie level per 100 g. Your “per cup” calories can rise after cooking because cooked florets often pack tighter and a cup can weigh more.
When you’re eyeballing a portion, ask one question: “How heavy is this serving?” Answer that, and the calorie math becomes plain.
Calories And Protein In Broccoli For Common Servings
Below are calorie and protein estimates built from FoodData Central values and typical serving weights used in nutrition databases. Use them as a tracking shortcut, then swap to grams when you want tighter control.
These numbers assume plain broccoli with no oil, cheese, sauces, or breading. Add-ins change the whole story fast.
Mid-article note on sources: FoodData Central is the USDA’s public nutrition database, and it’s the backbone for many trackers. You can learn how the database works and how the data are structured on the USDA FoodData Central API guide.
Daily Value context helps too. On U.S. labels, protein %DV is based on a 50 g reference amount listed by the FDA on its Daily Value table for Nutrition Facts labels.
| Serving (Plain Broccoli) | Calories | Protein (g) |
|---|---|---|
| 100 g raw (about 1 cup chopped) | 34 | 2.8 |
| 1 cup chopped raw (about 90 g) | 31 | 2.5 |
| 1 cup florets raw (loose pack, about 70 g) | 24 | 2.0 |
| 1 medium stalk (about 150 g) | 51 | 4.2 |
| 85 g raw (common “side” portion) | 29 | 2.4 |
| 100 g cooked, drained | 35 | 2.4 |
| 1 cup chopped cooked (about 155 g) | 54 | 3.7 |
| 2 cups cooked (about 310 g) | 109 | 7.4 |
Why Your Tracker Might Show Higher Numbers
If you’ve ever logged broccoli and seen a triple-digit calorie count, it usually comes from one of three things: a heavier cooked cup, a “with sauce” entry, or a branded frozen blend with added ingredients.
Cooked cups weigh more than you think
A cup of chopped cooked broccoli can weigh far more than a cup of chopped raw broccoli. If you log “1 cup” using a raw entry, you undercount. If you log “1 cup” using a cooked entry for a small pile of roasted florets, you overcount. Grams keep you honest.
Oil is the quiet calorie multiplier
Roasting often uses oil. One tablespoon of oil can add over 100 calories. That single step can turn a low-calorie vegetable into a side dish that eats a big chunk of your meal budget.
Cheese and creamy sauces change protein, too
Cheese sauce raises protein, yet it raises calories even faster. If your goal is a higher-protein plate, you’ll get a cleaner trade when you pair broccoli with a lean protein instead of drowning it in a rich topping.
How Much Protein Is In Broccoli, And What It Can Do For A Meal
Broccoli’s protein looks small next to meat, beans, or dairy. Still, it adds up when you eat real portions. Two cups of cooked broccoli can push past 7 grams of protein, and that’s before you add any main protein.
Broccoli protein is a “bonus,” not a base
Think of broccoli as a protein helper. It bumps the protein total of a meal while also bringing fiber and micronutrients. For a high-protein day, you still want a main protein source.
Pair broccoli with proteins that match your goal
If you’re building meals for satiety, pick a protein that fits your calorie target. Chicken, fish, eggs, tofu, tempeh, lentils, and Greek yogurt all work. The best pick is the one you’ll cook and eat on repeat.
Use the 50 g protein Daily Value as a quick yardstick
If a serving of broccoli gives you 3 to 4 grams of protein, that’s a small slice of the FDA’s 50 g reference amount. That framing helps you see broccoli as part of the total, not the whole plan.
Raw Vs Cooked Broccoli Calories: What Changes On The Plate
Raw broccoli feels “lighter” because it takes up space and crunches slow. Cooked broccoli feels “denser” because the same plant matter takes less volume after heat and time.
Steaming keeps calories steady
Steaming adds no calories. If you want broccoli as a low-calorie anchor, steaming is the easy win. Season with salt, pepper, garlic, lemon, or chili flakes, and you’re done.
Roasting can stay low-calorie with a measured approach
You can roast broccoli and still keep calories in check. The trick is measuring oil. Toss florets with a teaspoon per tray, not a free pour, and use high heat so you get browning without soaking the veg.
Boiling and draining changes the cup math
Boiled broccoli can end up softer and more compact. That can raise the grams in a “cup,” which raises calories per cup. If you log by weight, boiled vs steamed barely changes your totals.
Portion Tricks That Make Broccoli Easy To Eat
Broccoli is one of those foods that’s either a weekly staple or a sad bag in the crisper. The gap is prep. A few small habits make it easy to eat broccoli without thinking about it.
Cut once, eat twice
When you bring broccoli home, wash and dry the head, then cut it into florets and stem sticks. Store it in a container lined with a paper towel. Now it’s ready for snacks, stir-fries, and sheet pans.
Don’t wash it early if you store it wet
Moisture speeds spoilage. The FDA advises storing perishable produce in a clean refrigerator at 40°F or below and gives practical steps in its produce handling and storage guidance.
Keep food safety simple
Cooked broccoli is perishable. Follow the same basics you’d use for any cooked food: don’t leave it out for long stretches, chill it promptly, and reheat it hot. CDC’s food safety prevention page lays out the “Danger Zone” concept and the 40°F–140°F range in plain language on its food poisoning prevention guide.
Broccoli Meal Math That Doesn’t Feel Like Homework
You don’t need a perfect log to get value from broccoli. You need repeatable meals. Use broccoli as the volume base, pick a protein, then add a carb or fat that fits your day.
Three patterns that work on busy nights
- Sheet-pan dinner: broccoli + protein + a starch, all roasted with measured oil.
- Stir-fry bowl: broccoli + tofu or chicken + sauce that you measure once and reuse.
- Soup or skillet: broccoli stirred into a pot with beans, lentils, or shredded chicken.
Use the table below as a quick way to raise protein while keeping broccoli at the center of the plate. Protein values vary by brand and cooking method, so treat these as rough targets, not lab results.
| Broccoli Pairing | Typical Portion | Protein Add (g) |
|---|---|---|
| Chicken breast, cooked | 3 oz (85 g) | 25–27 |
| Firm tofu | 3 oz (85 g) | 8–10 |
| Tempeh | 3 oz (85 g) | 16–18 |
| Cooked lentils | 1/2 cup | 8–9 |
| Cooked chickpeas | 1/2 cup | 7–8 |
| Nonfat Greek yogurt | 3/4 cup | 15–18 |
| Eggs | 2 large | 12 |
Common Questions People Have While Logging Broccoli
Why does frozen broccoli list different calories?
Plain frozen broccoli tends to match fresh broccoli closely when you compare by 100 g. Differences pop up when the bag includes sauce, cheese, rice, or seasoning blends. Check the ingredient list and log the branded item when it’s more than broccoli.
Is broccoli a “high-protein vegetable”?
Per calorie, broccoli does well. Per bite, it’s still a vegetable. If your goal is muscle gain or a high-protein target, broccoli helps, yet it won’t replace a main protein source.
Does cooking destroy broccoli protein?
Protein is stable under normal cooking. What changes is water. The same amount of broccoli can weigh less after cooking, which can shift what a “cup” means.
Can broccoli help with fullness?
Broccoli’s fiber and volume can help you feel full for the calories you eat. Pair it with a solid protein and you’ve got a plate that holds you for longer than a bare vegetable side.
Simple Takeaways For Today
- For clean tracking, weigh broccoli in grams and use per-100 g values as your base.
- Expect cooked cups to weigh more than raw cups. “One cup” is not a fixed unit across cooking methods.
- Broccoli adds protein, but it works best as a helper next to a main protein.
- Watch oil and rich sauces, since they can outrun broccoli’s low calorie load in a hurry.
