How Many Calories Is Broccoli? | Serving Sizes That Matter

One cup of chopped raw broccoli has 31 calories; a cooked cup lands near 55, before oils or sauces.

Broccoli is easy to log until the portion labels get fuzzy. “A cup” can mean loose florets, tight chop, raw, cooked, or roasted. The vegetable stays low-calorie, yet the measuring style can swing the number, and add-ons can swamp it.

Below you’ll get dependable calorie numbers for common portions, plus a simple way to measure any serving so your food log stays steady.

Calories In Broccoli By Serving Size And Cooking Style

Raw broccoli: the baseline

USDA data for raw broccoli lists 34 calories per 100 grams. A common household measure in that same entry is 1 cup chopped (91 g) at 31 calories. You can view the nutrient panel on the USDA FoodData Central raw broccoli listing.

Cooked broccoli: same veg, denser cup

Cooking doesn’t add calories on its own. It changes water content and shape, so “one cup” stops matching a raw cup. USDA data for boiled, drained broccoli lists 35 calories per 100 grams, and 1 cup chopped cooked (156 g) at 55 calories. See the entry on the USDA FoodData Central cooked broccoli listing.

Why cups shift so much

Cup measures change with three things:

• Piece size: Big florets trap air; small chop packs tight.
• Stem mix: Stems pack denser than loose florets.
• Cook method: Steamed stays plump; roasted dries out.

If you want fewer surprises, weigh in grams and use a per-100-gram entry. If you prefer cups, stick with one style so your log stays consistent.

Why Broccoli Calories Climb In Real Meals

Oil changes the math

Plain broccoli is light. Oil is dense. One tablespoon of olive oil is 119 calories in USDA data, which can beat the calories in a full cup of chopped raw broccoli. The fix is simple: measure oil with a spoon, not “a drizzle.” Here’s the USDA FoodData Central olive oil listing for the exact number.

Sauces and cheese can take over

Broccoli in cheese sauce, creamy soups, and casseroles should be logged as the dish, not as broccoli. When dairy, butter, or dressing is in the mix, those ingredients usually carry most of the calories.

Restaurant broccoli often arrives dressed

Takeout broccoli may come glossy from oil or butter, or coated in sauce. If you can see shine, log a bit of oil or choose a dish entry in your tracker that matches the meal.

Ways To Measure Broccoli Calories Without Guessing

Grams: the cleanest option

Weigh broccoli before cooking if you log raw entries, or after cooking if you log cooked entries. Then multiply grams by calories per gram (raw: 0.34; cooked boiled/drained: 0.35). Round to the nearest whole calorie and move on.

Cups: make them repeatable

If you use cups, use a measuring cup, drop broccoli in without smashing it down, then level the top. Log with the matching measure in your tracker: “cup chopped” for small pieces, “cup florets” for larger pieces.

Frozen broccoli labels: match grams to the bag

Frozen broccoli bags list a serving size in cups and grams. If you weigh your portion in grams, the label becomes easy to follow. The FDA explains how serving size and calories work on packaged foods in its Nutrition Facts label explanation.

Raw-to-cooked swaps in your tracker

If you weigh broccoli raw, log it as raw even if you eat it cooked. The calories stay tied to the raw grams you measured. This keeps things simple when you roast a tray, steam a batch, or microwave a bowl.

If you only weigh it after cooking, log it as cooked and pick a cooked entry that matches your method. Boiled and drained broccoli holds a bit more water than roasted broccoli, so cooked weights can differ from day to day. Your scale still keeps the log steady.

Broccoli Portion And Calorie Table

The table below uses USDA FoodData Central calorie density (raw: 34 kcal per 100 g; cooked boiled/drained: 35 kcal per 100 g). Portion weights reflect common household measures. Calories are calculated from those per-100-gram values, rounded to whole numbers.

Portion	Weight (g)	Calories
Raw broccoli, 100 g	100	34
Raw broccoli, 1 cup chopped	91	31
Raw broccoli, 1/2 cup chopped	46	16
Raw broccoli, 1 spear (about 5 inches)	31	11
Cooked broccoli, 100 g	100	35
Cooked broccoli, 1 cup chopped	156	55
Cooked broccoli, 1/2 cup chopped	78	27
Cooked broccoli, 1 cup florets (loose fill)	120	42

Broccoli Calories In Common Dishes

Roasted broccoli on a sheet pan

Roasted broccoli tastes richer, yet calories mainly come from oil. A fast way to log it: weigh the broccoli, measure oil, then divide the oil across servings.

Example: 500 g raw broccoli is 170 calories (500 × 0.34). Add 1 tablespoon of oil (119). Pan total: 289. Split into four servings and each serving lands at 72 calories.

Stir-fry broccoli with a sauce

Stir-fry can stay light if you start with a measured teaspoon of oil and use splashy liquids (water, broth, soy sauce) to keep the pan moving. Bottled sauces vary a lot, so log the serving from the label, or save your homemade sauce as a recipe entry.

Soups, pasta, and casseroles

In mixed dishes, broccoli is rarely the calorie driver. Cheese, cream, pasta, rice, and breadcrumbs usually carry the bulk. If you want accurate numbers, build the recipe once in your tracker and reuse it for leftovers.

Steamed broccoli as a weeknight side

Steaming is the simplest path for low calories, since you can skip oil. If you add butter, measure it. A pat can turn into two tablespoons without you noticing, especially when it melts into the florets.

Broccoli “rice” and bagged slaw mixes

Riced broccoli and slaw-style mixes are still broccoli, yet the portion entries in apps can be messy. If the package has a label, using the label serving in grams is often the least confusing route. If there’s no label (a loose produce bin), grams plus a raw broccoli entry works well.

Meal prep and leftovers

If you cook a big batch, log the full recipe once, then divide it into containers. That way each container inherits the same calorie math, and you don’t redo work each lunch. When a dish includes oil, cheese, or sauce, recipe logging saves the most time.

Easy Portion Checks Without A Scale

No scale? You can still stay close with a repeatable cup measure and a few visual checks. The goal is consistency, not perfection.

• A loose cup of raw florets is often lighter than a tight cup of chopped pieces.
• A dinner-plate side that covers a third of the plate is often 1 to 2 cups cooked, depending on how it’s piled.
• If broccoli is the bulk of a bowl, log it as cooked cups, then log any toppings and sauces separately.

If you get a scale later, weigh your “usual cup” once. That one number can make cup logging much steadier.

Calorie Add-Ons That Change A Broccoli Bowl

These extras can double (or triple) the calories of a serving fast. Portions are common serving sizes for home cooking.

Add-on	Typical Portion	Calories Added
Olive oil	1 tbsp	119
Butter	1 tbsp	102
Shredded cheddar	1 oz (28 g)	114
Ranch dressing	2 tbsp	120
Sesame seeds	1 tbsp	52
Bread crumbs	2 tbsp	50

Why Broccoli Feels Filling For Few Calories

Broccoli has lots of water and fiber. That gives you a big bowl to chew through for a low calorie cost. If you want a meal that sticks with you, pair broccoli with protein and a measured fat source, then you’ll get satisfaction without losing the numbers.

Simple Habits For Tracking Broccoli Without Stress

• Pick one logging style: raw grams, cooked grams, or cups. Keep it steady for a while.
• Measure oil first: pour into a spoon, then into the pan.
• Log sauces as their own item: broccoli with cheese sauce is a different food entry than plain broccoli.

Flavor tricks that stay low-calorie

Broccoli doesn’t need a lot of fat to taste good. Try salt plus a squeeze of lemon, a splash of vinegar, or a spoon of salsa. Garlic, black pepper, chili flakes, and smoked paprika work well too. If you like cheese, use a small measured sprinkle, then stop. A little goes a long way once it hits hot florets.

For roasted broccoli, let the tray get hot before you add the vegetables. That helps browning without extra oil. For steamed broccoli, drain well and season right away so the flavor sticks.

Broccoli Calorie Checklist Before You Hit “Save”

• Raw logged as raw, cooked logged as cooked.
• Grams weighed, or cups measured the same way as last time.
• Oil, butter, cheese, dressing, and toppings logged too.
• Mixed dishes logged as the dish or recipe, not as “broccoli.”

If your numbers still feel jumpy, pick one broccoli entry in your app and stick with it for two weeks. Track add-ons by spoon or label. That steady routine will show you what you eat, without the noise from switching entries every meal.

Once you lock in your measuring style, broccoli turns into a low-calorie base that’s easy to build on. Most of the work is just catching the extras. If you measure oil, you’ll rarely be surprised by broccoli calories again today.
