How Much Fiber In Brocolli? | What Each Serving Gives

One cup of raw chopped broccoli has about 2.4 grams of fiber, while a cooked cup has about 5.1 grams.

If you’re counting fiber, broccoli earns its spot on the plate. It’s not in the same class as beans or bran cereal, but it still gives a solid bump, and it does it without piling on many calories. That makes it an easy vegetable to lean on when you want meals that feel filling.

The number changes with serving size and cooking style. A loose cup of raw florets holds less broccoli by weight than a soft, packed cup after cooking, so the cooked cup looks richer in fiber. Once you see that, the numbers make more sense.

How Much Fiber In Brocolli? Raw Vs Cooked

Here’s the plain answer. Raw chopped broccoli gives about 2.4 grams of fiber per cup. Raw broccoli also lands at about 2.6 grams per 100 grams. Cooked broccoli comes in higher per cup, with about 5.1 grams, since the pieces shrink and hold less water after cooking.

That gap trips people up. It can look like cooking adds fiber, but that’s not what’s happening. The fiber in the broccoli stays in the plant. What changes is volume. A cooked cup holds more actual broccoli than a fluffy raw cup, so the fiber total per cup goes up.

If you want a rough rule, use this:

• Raw chopped cup: about 2.4 grams
• 100 grams raw: about 2.6 grams
• Cooked cup: about 5.1 grams

That means broccoli is a steady fiber food, not a fiber giant. A side dish gives you a decent chunk. A large serving, or a bowl mixed with beans or whole grains, starts to add up in a real way.

Why A Cooked Cup Looks Higher

Heat softens broccoli and drives off water. The florets collapse, the stems soften, and the same bowl can now hold more food by weight. So when you compare cup to cup, cooked broccoli wins. When you compare equal weights, the gap narrows and the story feels less dramatic.

That’s why labels and food databases can look odd at first glance. A “cup” is handy in the kitchen, but grams tell the cleaner story. If you want the clearest read, weigh it.

Fiber In Broccoli By Serving Size

The table below uses common serving sizes and rounded values, so you can size up a snack, side, or full plate without doing math in your head. These numbers are close enough for meal planning and grocery shopping.

The data line up with entries in USDA FoodData Central, then scale to everyday portions. Raw and cooked entries are both useful, since people eat broccoli both ways.

Serving	Fiber	What That Looks Like
50 g raw	1.3 g	Small handful of chopped broccoli
75 g raw	2.0 g	Snack box portion
100 g raw	2.6 g	Good baseline for tracking
1 cup raw chopped	2.4 g	Common salad or veggie tray serving
150 g raw	3.9 g	Big raw side
200 g raw	5.2 g	Large dinner portion
1/2 cup cooked	2.6 g	Small cooked side
1 cup cooked	5.1 g	Full cooked side dish
1 1/2 cups cooked	7.7 g	Big bowl with dinner

What Changes The Fiber Count On Your Plate

Serving size is the big one, but it’s not the only one. Raw, steamed, roasted, and boiled broccoli can all land a bit differently by cup since water shifts the weight and the way the pieces settle in the bowl. The food itself doesn’t turn into a different fiber source. The measuring method changes the read.

Stems Count Too

A lot of people toss the stem and eat only the florets. That leaves fiber on the cutting board. Peel the rough outer layer, slice the inner stem thin, and cook it with the florets. It’s crisp, mild, and worth keeping.

Sauces Don’t Fix A Low-Fiber Plate

Cheese sauce or butter can make broccoli easier to eat, but they don’t do much for fiber. If you want the meal total to rise, pair broccoli with foods that carry more grams on their own. Chickpeas, lentils, brown rice, barley, and whole-wheat pasta work well without turning dinner into a chore.

Cooking Style Changes Volume More Than Fiber

Steamed broccoli stays plump. Roasted broccoli dries out more and tastes sweeter. Boiled broccoli can get soft fast. Those changes matter for texture and bowl size. They matter less for the fiber in the broccoli itself.

How Broccoli Fits A 28-Gram Fiber Day

On food labels, the FDA Daily Value for dietary fiber is 28 grams. That gives you a simple yardstick. A raw chopped cup of broccoli lands around 9% of that mark. A cooked cup lands around 18%.

That’s a nice lift from one vegetable, but broccoli won’t carry the whole day by itself. The Dietary Guidelines for Americans point people toward a mix of vegetables, fruit, beans, and whole grains across the day. Broccoli fits that pattern well. It just works best as one player, not the full team.

If you eat broccoli with a bean salad at lunch, oats in the morning, and fruit later on, the grams stack up without much fuss. That’s the part people miss. Fiber usually comes from a string of decent choices, not one magic food.

Serving	Fiber	Share Of 28 g Daily Value
1/2 cup raw	1.2 g	4%
1 cup raw chopped	2.4 g	9%
100 g raw	2.6 g	9%
1/2 cup cooked	2.6 g	9%
1 cup cooked	5.1 g	18%
1 1/2 cups cooked	7.7 g	28%

Easy Ways To Get More Fiber From Broccoli

Broccoli gets easier to eat in larger amounts when you stop treating it like a plain side dish. It slides into meals well, and that’s where the grams start climbing.

• Roast a full tray, not one serving. Leftovers disappear into eggs, rice bowls, and pasta.
• Keep the stems. Slice them thin so they cook at the same pace as the florets.
• Mix broccoli with beans or lentils when you want the meal total to jump.
• Chop it small for soups and stir-fries, where a cup goes down with less chewing.
• Steam it until just tender if raw broccoli feels rough on your stomach.

If your gut gets noisy when you raise fiber, go step by step and drink water across the day. A giant pile of vegetables after a low-fiber week can feel like a lot. Smaller jumps usually land better.

Where Broccoli Lands

Broccoli gives a solid amount of fiber for a vegetable people can buy, cook, and eat without much trouble. A raw chopped cup gives about 2.4 grams. A cooked cup gives about 5.1 grams. That makes it a good daily player, even if it’s not the top dog in the fiber race.

If you want the cleanest answer to the question, use raw broccoli at 2.6 grams per 100 grams and cooked broccoli at 5.1 grams per cup. Then build from there based on how you cook it and how much lands on your plate.
