Calories And Protein In 1 Cup Broccoli | Numbers That Matter

One cup of chopped raw broccoli has 31 calories and 3 g protein; a “cup” of cooked broccoli can land lower or higher based on how it’s packed.

If you’ve ever logged broccoli and gotten two different totals, you’re not losing your mind. “1 cup broccoli” sounds fixed, yet the numbers move because cups measure volume, not weight. Raw florets trap air. Cooked broccoli shrinks and holds water. Even “chopped” vs “florets” changes how much fits.

This article pins down the most common “1 cup” you’ll see in nutrition databases, then shows how to choose the right entry in your tracker so your calorie and protein math stays clean.

What “1 Cup Broccoli” Means On Labels And Trackers

A cup is a volume measure. That’s handy in a kitchen, but it’s a noisy signal for nutrition. A tightly packed cup weighs more than a loose cup, so it brings more calories and protein.

Two shortcuts help:

• If you’re eating raw chopped broccoli, many databases treat 1 cup as 91 g, which comes out to 31 calories and 3 g protein.
• If you’re eating cooked broccoli, 1 cup can mean “chopped, boiled, drained” or a similar cooked form, with a different weight and different totals.

When you want a steady definition of a “cup” in food groups, the U.S. MyPlate cup table lists broccoli as “1 cup, chopped or florets, fresh or frozen” as a 1-cup vegetable amount. That’s helpful for meal planning, even though it doesn’t lock calories to a single number. MyPlate cup amounts for vegetables

Calories And Protein For One Cup Of Broccoli In Real Kitchens

Here’s the cleanest baseline that matches what many people mean by “1 cup broccoli” at home: 1 cup chopped raw broccoli (91 g). USDA SNAP-Ed lists that serving at 31 calories and 3 g protein. USDA SNAP-Ed broccoli nutrition (1 cup chopped)

Now the twist: a cup of cooked broccoli is not the same “amount of broccoli” as a cup of raw chopped. Cooking changes volume. Chopping changes packing. Draining changes water content. So cooked entries often land in a different calorie and protein lane per cup.

If you want a direct cooked reference from a nutrient database, FoodData Central’s listing for “broccoli, cooked, boiled, drained, without salt” provides a 1-cup chopped measure with calories and protein tied to that prepared state. USDA FoodData Central broccoli (cooked, boiled, drained)

Use the raw-chopped baseline when you’re snacking on raw broccoli, tossing chopped broccoli into salads, or measuring chopped florets into a cup before cooking. Use the cooked entry when the broccoli is already cooked and you’re scooping it onto a plate.

Why The Numbers Change So Much Between Raw And Cooked Cups

Most of the swing comes from three plain things:

• Packing: Big florets leave gaps. Finely chopped pieces settle and pack tighter.
• Shrink: Heat collapses the structure. The same starting broccoli takes up less space once cooked.
• Water: Steaming and boiling can leave water clinging to pieces. Draining time matters.

So a “cup” isn’t just broccoli. It’s broccoli plus the empty space between pieces, plus any water stuck to it. That’s why weighing can feel calmer than scooping.

If you want the most repeatable log, weigh your broccoli in grams and match it to a gram-based entry in USDA FoodData Central for the form you’re eating. USDA FoodData Central broccoli (raw)

How To Log 1 Cup Broccoli Without Guesswork

Pick the option that matches what’s on your plate:

• Raw, chopped: Use the 1 cup chopped (91 g) entry when your cup is filled with chopped pieces.
• Raw florets: If you used florets and they sit loose in the cup, calories and protein will trend lower than tightly packed chopped.
• Cooked, drained: If the broccoli is cooked, log the cooked entry. Let it drain a moment so you’re not logging extra water weight as food.
• Frozen cooked: Frozen broccoli can be cut smaller and can pack tighter once cooked. Use a frozen-cooked entry if your tracker offers it.

If your tracker only offers “1 cup broccoli” with no prep details, treat it like a rough placeholder and tighten it by switching to a USDA-based entry with a clear description.

Calories And Protein In 1 Cup Broccoli Across Common Prep Styles

The table below shows how “one cup” shifts with prep and cut. Use it as a quick chooser for the right logging entry. When a row lists a range, that range reflects how a cup packs in real life plus common database variation across cup definitions.

1-Cup Measure (Typical Use)	Calories	Protein
Raw broccoli, chopped (cup filled with chopped pieces)	31	3 g
Raw broccoli florets (loose cup, bigger pieces)	20–30	2–3 g
Raw broccoli, finely chopped (packed cup)	30–40	3–4 g
Cooked broccoli, chopped, boiled and drained (cup scooped after cooking)	25–35	2–3 g
Cooked broccoli, steamed (tender-crisp, lightly drained)	25–40	2–4 g
Frozen broccoli, cooked (often smaller cuts, packs tighter)	25–45	2–4 g
Broccoli slaw, raw (shredded, packs tight)	20–40	2–4 g
Broccoli “rice,” raw (very small pieces, packs tight)	25–45	2–4 g

Want one number you can trust when you don’t feel like debating cup packing? Use the raw chopped benchmark: 31 calories and 3 g protein per cup. It’s widely referenced and easy to match to how many people actually measure broccoli at home. USDA SNAP-Ed broccoli (1 cup chopped)

Protein In Broccoli: What It Adds And What It Doesn’t

Broccoli gives you some protein for a small calorie cost. In raw chopped form, that’s 3 g protein for 31 calories, which is a tidy trade when you’re building volume in meals.

Still, broccoli isn’t a “main protein” food. It’s a strong helper. It nudges your total up while bringing fiber and micronutrients along for the ride.

If you’re tracking macros, this is the most useful way to think about it: broccoli is a low-calorie base that lets higher-protein foods fit into your day without the plate feeling skimpy.

How Cooking Changes The Cup Without Changing The Broccoli

Cooking changes the space broccoli takes up. It also changes how much water sits on it. That shifts “per cup” math even when you started with the same stalk.

Here’s the kitchen move that keeps your log consistent: measure broccoli the same way each time. Either:

• Weigh it raw before cooking and log the raw grams, or
• Weigh it cooked after draining and log cooked grams.

Both work. Mixing them is where tracking gets messy.

Smart Ways To Measure One Cup Without A Scale

If you don’t own a scale, you can still tighten your estimate:

• Choose one cut: either chopped or florets. Keep that choice steady.
• Use the same cup: the same measuring cup, not a random mug.
• Don’t mash it down: fill the cup the same way each time.
• Drain cooked broccoli: let it sit in a colander for a short moment, then measure.

Serving-size charts can also help when you’re building meals around “cups of vegetables.” The FDA’s raw vegetable nutrition table lists standard serving sizes and nutrients for many vegetables, including broccoli, in a single place. FDA nutrition information for raw vegetables

Common Logging Mistakes That Inflate Or Deflate Your Numbers

Using A Cooked Entry For Raw Broccoli

Cooked entries can assume a different weight per cup. If you eat raw and log cooked, your calories and protein can drift.

Logging “1 Cup” When You Ate A Bowl

A cereal bowl can hold two cups or more, even when it looks like one serving. If you’re making broccoli the base of a meal, check how many cups you truly scooped.

Ignoring The Cut

Chopped packs tighter than florets. A packed cup has more broccoli, so it brings more calories and more protein.

Counting Sauce As Broccoli

Cheese sauce, butter, oil, and creamy dips can dwarf broccoli’s calories. Log those add-ons separately so broccoli doesn’t take the blame.

Fast Meal Math Using The Raw Chopped Baseline

If you stick with the 1 cup chopped raw baseline (31 calories, 3 g protein), you can do quick head math:

• 2 cups chopped raw: 62 calories, 6 g protein
• 3 cups chopped raw: 93 calories, 9 g protein
• 4 cups chopped raw: 124 calories, 12 g protein

That’s why broccoli works so well as volume on a plate. You can scale it up without your calorie total spiking.

Table: Quick Checks To Match Your Broccoli Entry

If Your Broccoli Looks Like…	Best Tracker Entry To Pick	Why It Fits
Small chopped pieces in a measuring cup	“Broccoli, raw, chopped, 1 cup (91 g)”	Matches a common cup definition tied to a gram weight.
Big florets with lots of air gaps	“Broccoli florets, raw, 1 cup”	Loose packing means less broccoli per cup.
Soft cooked broccoli scooped onto a plate	“Broccoli, cooked, boiled, drained, 1 cup, chopped”	Cooked volume and water change the cup’s weight.
Frozen broccoli after cooking	“Broccoli, frozen, cooked” entry	Cut size and packing often differ from fresh.
Broccoli with oil, butter, cheese, or mayo dip	Log broccoli + log the add-on	Add-ons can carry most of the calories.
Broccoli in a mixed dish (stir-fry, casserole)	Weigh the whole recipe, then portion	Mix-ins blur “cups,” so recipe logging stays steadier.

How To Make Broccoli Add More Protein Without Adding Many Calories

Broccoli already plays nice with calorie budgets, so the goal is to pair it with protein that stays lean and simple. A few easy moves:

• Use Greek yogurt as a dip base, then season it like ranch.
• Toss broccoli into egg dishes like omelets or frittatas.
• Pair it with beans or lentils in a bowl meal.
• Stir in tofu or chicken and keep oil measured.

That keeps broccoli doing its job—bulk, crunch, color—while your protein target gets hit by the partner food.

A Practical Takeaway You Can Use Tonight

If you’re counting calories and protein and you want one clean default, log 1 cup chopped raw broccoli as 31 calories and 3 g protein. If your broccoli is cooked, switch to a cooked entry, since a cooked cup is a different thing in volume and water.

That one habit—matching the entry to the prep—removes most tracking surprises.
