How Many Calories Are In Broccoli And Cauliflower? | Smart Plate Math

Calories In Broccoli Vs Cauliflower: Raw, Cooked, And Riced

Both are low-energy, high-volume vegetables. Raw broccoli commonly shows about 31 kcal per 100 g, while raw cauliflower sits near 27 kcal per 100 g. Cooked values drift based on water loss and added fat. Steam or boil keeps totals close to raw; roasting pushes numbers up when oil enters the pan.

Big-Picture Nutrition Snapshot (Per 100 Grams)

This table keeps it simple across common forms. Numbers reflect typical database values; small swings happen by variety, cut size, and doneness.

Form	Calories (per 100 g)	Notes
Broccoli, Raw	~31 kcal	Water-rich; fiber about 2.6 g
Cauliflower, Raw	~27 kcal	Very low sugar; fiber about 2.0 g
Broccoli, Steamed/Boiled	~28–35 kcal	Minor change from raw
Cauliflower, Steamed/Boiled	~23–30 kcal	Soft texture; mild flavor
Broccoli, Roasted (light oil)	~50–80 kcal	Oil use drives the range
Cauliflower, Roasted (light oil)	~50–90 kcal	Crips edges; watch portions
Cauliflower “Rice” (no oil)	~20–30 kcal	Great rice swap by volume
Broccoli Stems (raw/trimmed)	~25–30 kcal	Slice thin; same macros trend

Serving Sizes You’ll See In Real Life

Labels and recipes rarely use 100 g. Expect cups and packed portions. A cup of cooked florets weighs less than a cup of raw, so cup-based calories can look closer than the raw-by-weight numbers suggest.

Why Totals Change With Heat

Cooking alters water content. Steam keeps water inside; boiling leaches some into the pot; roasting drives off moisture and often adds oil. Salt doesn’t add calories, but oil does. A tablespoon of oil brings ~119 kcal, so a light spray or measured teaspoon makes a big difference across a sheet pan.

How To Keep Calories Low Without Losing Flavor

Go heavy on aromatics and light on fat. Toss florets with lemon, garlic, chili flakes, and a measured teaspoon of olive oil for a whole tray. Finish with vinegar or citrus to lift flavor without extra energy. If you blend soups, add potato or white beans to thicken instead of cream.

Per-Cup Reference Numbers

For daily tracking, cups are handy. A cup of cooked broccoli often lands around 30–55 kcal; a cup of cooked cauliflower lands in a similar neighborhood when made without cream or butter. Crisp roasting raises the range fast if oil pools.

Micros That Matter

Both pack vitamin C and folate. Broccoli tends to edge higher on vitamin C per cup. For a clear government overview of produce basics, USDA’s broccoli produce guide and the companion page for cauliflower are solid refreshers on selection and storage tips.

Early Meal-Plan Math (Natural Flow Interlink)

Snack veggies fit better once you set your daily calorie needs. That baseline tells you how many cups of florets you can pile next to protein at lunch and dinner.

Smart Swaps And Pairings

Use chopped florets to bulk up stir-fries, pasta bowls, and sheet-pan dinners. Cauli rice brings volume to bowls in place of part of the grain. Pair either vegetable with lean meats, tofu, eggs, or beans for staying power. A squeeze of lemon or a spoon of yogurt-based sauce adds brightness for minimal calories.

Cooking Methods Ranked By Calorie Impact

From lightest to heaviest: raw, steaming, microwaving, brief sauté with spray, roasting with measured oil, pan-frying with free-pour oil, creamy bakes. The jump from a spray to a tablespoon is big. Keep a measuring spoon near the stove.

Fiber, Carbs, And Protein—What To Expect

Per 100 g, broccoli brings around 2.5–3 g of fiber and ~2.5–3 g of protein, with low sugars. Cauliflower tracks close, usually a touch lower on fiber and protein. These aren’t protein powerhouses, but they do make your meal more filling for the calories.

Portion Guide You Can Use Tonight

Use this table when you portion by cups or by the plate. It’s handy for logging or quick mental math at dinner.

Portion	Calories	Practical Tip
1 Cup Raw Broccoli	~25–30 kcal	Snack with salsa or hummus
1 Cup Raw Cauliflower	~20–25 kcal	Great for crunchy slaws
1 Cup Cooked Broccoli	~30–55 kcal	Steam or microwave for speed
1 Cup Cooked Cauliflower	~25–50 kcal	Blend into soups for body
1 Cup Cauli Rice (plain)	~20–35 kcal	Mix 50/50 with grain
Roasted Tray (300 g florets)	~150–240 kcal*	*1–2 tsp oil changes the range
Broccoli-Heavy Salad Bowl	~120–200 kcal*	*Depends on dressing splash

Raw Versus Cooked: Which Suits Your Goal?

For pure calorie control, raw and steamed sit at the low end. If texture and flavor matter more, a light roast gives caramelized edges for a small calorie trade. If you’re tracking vitamins, a short steam keeps color and tenderness with minimal loss.

When Numbers Seem Off

Restaurant sides can include butter or cheese. That’s where a “30 kcal per cup” side becomes a 200-plus kcal dish. Ask for oil on the side, or request a steam-only preparation and add lemon at the table.

Budget Tips That Also Cut Calories

Buy whole heads and use stems for slaws or stir-fries. Frozen florets work well for steaming and soup, and they’re already trimmed. If you roast from frozen, preheat the sheet pan and go light on oil to offset surface moisture.

Quick Builds Under 300 Calories

Garlic-Lemon Steam Bowl

Two cups steamed florets, 1 teaspoon olive oil, squeeze of lemon, salt, pepper, chili flakes. Add grilled chicken or tofu if you need more protein.

Sheet-Pan Mix

Broccoli and cauliflower florets, onion wedges, a measured teaspoon of olive oil for the whole tray, roasted at 220°C. Finish with balsamic. Pile next to fish or beans.

Blended Cauli Soup

Simmer cauliflower with onion and garlic in stock, blend smooth, and finish with a spoon of yogurt. Creamy texture with no heavy cream.

FAQs You Don’t Need—Just Straight Answers

Which One Is Lower In Calories?

By weight, raw cauliflower comes in a touch lower than raw broccoli. In cups, both look similar once cooked.

Does Roasting Always Add A Lot?

Not if you measure oil. A teaspoon over a full tray is a small bump spread across many servings.

What About Cheese Sauce?

Delicious, but it changes the math. If you want a creamy vibe with fewer calories, blend in a spoon of light cream cheese or use a yogurt-based drizzle.

Where The Numbers Come From

Nutrition databases agree on the overall picture: both vegetables are low-calorie, high-fiber, and rich in vitamin C. A clear snapshot of raw values appears in MyFoodData’s pages linked in the card above. Those pages compile database entries and map to U.S. labeling rules. For produce handling basics, the USDA SNAP-Ed guides linked earlier are helpful for shopping and storage.
