One cup of cooked sprouts has about 56 calories and 4 g of protein, plus fiber and vitamin K that help meals feel more filling.
Brussels sprouts have a funny reputation. People either love them or they swear they taste like tiny cabbages with an attitude. The truth is simpler: they’re a low-calorie vegetable with a sneaky amount of protein for something that grows on a stalk.
If you’re tracking macros, building a plate that keeps you full, or trying to compare raw vs cooked nutrition, the details matter. A “cup” can mean a lot of different things once you roast, boil, or shred them into a salad. This article breaks down calories and protein in a way you can use while you cook and while you log.
Why Calories And Protein Change Once You Cook Them
Brussels sprouts don’t gain fat or sugar just because they hit a hot pan. What changes most is water. Raw sprouts hold a lot of water inside their leaves. Cooking shifts water content, which changes how nutrients look per cup, per sprout, or per 100 grams.
That’s why you’ll see different numbers depending on how the data is presented. A cooked cup can weigh more than you think if it’s boiled and still holding water. A roasted cup can weigh less because moisture evaporates and the leaves tighten up.
So the best way to compare is to pick one consistent unit, then translate it into real-kitchen servings. The most consistent unit is 100 grams. Next best is “1 cup cooked” when you want a fast mental shortcut.
Calories And Protein In Brussels Sprouts By Serving Size
If you only want one headline: Brussels sprouts are low in calories and moderate in protein for a vegetable. Raw sprouts sit around 43 calories and 3.4 g protein per 100 g. Cooked (boiled, drained) sprouts sit around 36 calories and 2.6 g protein per 100 g.
That drop does not mean cooking “removes” protein. It’s mostly a water-and-weight story, plus small differences in tested samples across datasets. For real life, both forms land in the same ballpark, and the bigger calorie swing usually comes from what you cook them with.
Raw Brussels Sprouts
Raw sprouts work well shredded into slaw, thin-sliced into salads, or tossed with lemon and salt. They’re crunchy, a bit peppery, and they take dressing like a champ.
For raw numbers, the cleanest reference is USDA FoodData Central entry for “Brussels sprouts, raw”. That’s where most trusted nutrition summaries pull their baseline data.
Cooked Brussels Sprouts
Boiling and draining is one common dataset entry because it’s standardized and easy to test. In real kitchens, roasting is more popular because it boosts flavor and browns the edges. Still, the boiled, drained numbers are a solid anchor point for logging.
For cooked values, see USDA FoodData Central entry for “Brussels sprouts, cooked, boiled, drained, without salt”. Use it as your baseline, then adjust for added oil, butter, bacon, nuts, or cheese.
What Counts As “One Serving” At The Table
A serving can be measured a few ways, and each one is useful:
- 100 g is best for apples-to-apples nutrition comparisons.
- 1 cup cooked is best for quick logging and meal planning.
- 6–8 medium sprouts is best when you’re counting pieces on a sheet pan.
When you’re tracking calories and protein, the cooking fat is often the hidden lever. Two teaspoons of olive oil can add more calories than the sprouts themselves. That’s not bad news. It just means your “sprouts macros” may be more about your pan than your produce.
What The Numbers Look Like In Real Portions
Below is a broad, cook-friendly table that translates common portions into calories and protein. Values are based on widely used USDA-backed entries for raw sprouts and cooked (boiled, drained) sprouts. Use it as a practical reference, not a lab report for your exact bag of sprouts.
| Serving | Calories | Protein |
|---|---|---|
| Raw sprouts (100 g) | 43 | 3.4 g |
| Cooked sprouts, boiled/drained (100 g) | 36 | 2.6 g |
| Cooked sprouts (1 cup, 156 g) | 56 | 4.0 g |
| Raw sprouts (1 cup) | Low-to-mid 40s | About 3–4 g |
| 6 medium sprouts (side dish size) | Roughly 30–45 | About 2–3 g |
| 12 medium sprouts (bigger side) | Roughly 60–90 | About 4–6 g |
| Roasted sprouts (sprouts only, no added fat) | Near cooked baseline | Near cooked baseline |
| Roasted sprouts (with 1 tbsp oil shared on tray) | Add 120 calories total | No added protein |
Notice how the “sprouts only” numbers stay calm, then the cooking fat changes the whole story. If your goal is higher protein without pushing calories too far, you’ll get more mileage pairing sprouts with lean protein than you will trying to treat sprouts as a protein food by themselves.
How Brussels Sprouts Fit Into A Higher-Protein Day
Brussels sprouts won’t carry your protein target alone. That’s not their job. Their job is to add volume, texture, fiber, and micronutrients while keeping calories modest. That combo can make it easier to stick with a plan that needs steady protein at each meal.
If you want a simple protein anchor, health authorities describe protein needs in broad ranges based on total calorie intake and body size. A clear overview is on the NIH-backed MedlinePlus page “Protein in diet”, which explains common recommendation ranges and why needs vary by person.
Think of sprouts as the side that keeps a high-protein plate from feeling tiny. Add chicken, fish, tofu, beans, eggs, Greek yogurt sauces, or tempeh and you get a meal that hits protein while staying satisfying.
Protein Per Calorie: Why Sprouts Feel “Macro Friendly”
People often call a food “macro friendly” when it gives you a lot of food volume for not many calories. Sprouts do that well. You can eat a big bowl of them and still have room for your main protein without blowing your day’s calories.
Also, sprouts bring fiber. Fiber is not protein, but it can help meals feel more filling and steady. That can make it easier to keep protein spaced across the day instead of playing catch-up at dinner.
They Bring More Than Macros
Even when you’re focused on calories and protein, it’s smart to know what else you’re getting. Brussels sprouts are part of the cruciferous family, and they’re known for compounds that form during chopping and chewing. Harvard’s Nutrition Source has a detailed overview on Brussels sprouts, including what’s known, what’s still being studied, and why variety across vegetables is a strong habit.
Common Logging Mistakes That Throw Off Calories And Protein
Counting A “Cup” Without Checking The Food Entry
One app’s “1 cup cooked” entry can match boiled sprouts, another can match roasted sprouts, another can match frozen cooked sprouts. Your best move is to pick one entry you trust and keep it consistent.
Forgetting Oil, Butter, Bacon Fat, Or Cheese
Sprouts can be a sponge for fats. That’s why they taste so good when roasted. If you’re using oil, weigh it or measure it. If you cook bacon first and toss sprouts in the drippings, log it as fat used in cooking.
Logging Raw Weight For Cooked Food
If you weigh sprouts raw, then roast them, the cooked pile will weigh less. If you log cooked weight using raw numbers, you’ll get mismatched calories and protein. Stick with one method: weigh raw and log raw, or weigh cooked and log cooked.
Cooking Methods That Keep The Numbers Predictable
Roasting With Measured Oil
Roasting gives you browned edges and a softer center. It also makes calorie tracking easy if you measure the oil. Toss sprouts with salt, pepper, and a measured amount of oil, then roast on a hot sheet pan so they brown instead of steaming.
Steaming
Steaming keeps the “sprouts only” calories close to the cooked baseline and avoids the extra fat unless you add it at the end. Finish with lemon, mustard, a little grated cheese, or a spoon of yogurt sauce.
Sautéing With A Spray Or A Small Spoon Of Oil
Sautéing can be a nice middle ground: more flavor than boiling, less oil than heavy roasting. Use a nonstick pan and a measured amount of oil so the calories stay predictable.
Protein Pairings That Work With Brussels Sprouts
If you want a higher-protein plate, build the meal around a protein source, then use sprouts as the volume and flavor carrier. Sprouts love sauces and spices, so they can make lean proteins feel less boring.
Here are protein pairings that are easy to repeat, with notes on why they work. This table is placed later in the article so you can use it as a practical “meal builder” section when you’re planning your week.
| Sprouts + Protein Combo | Why It Works | Easy Add-Ons |
|---|---|---|
| Roasted sprouts + chicken thighs or breast | Lean protein anchor with a savory, browned side | Garlic, lemon zest, Dijon |
| Sprouts + salmon | High protein with fats that make sprouts taste rich | Black pepper, capers, dill |
| Shaved raw sprouts + tuna salad | Crunchy base that turns tuna into a full bowl meal | Pickles, mustard, celery |
| Steamed sprouts + eggs | Fast breakfast-for-dinner plate with steady protein | Hot sauce, scallions, feta |
| Roasted sprouts + tofu | Plant protein that soaks up the same seasonings | Soy sauce, ginger, sesame |
| Sprouts + lentils | Protein plus fiber, great for meal prep bowls | Vinegar, herbs, red onion |
| Sprouts + Greek yogurt sauce | Adds protein without much volume, helps dryness | Lemon juice, garlic, salt |
| Sprouts + turkey meatballs | Easy portion control with a hearty feel | Tomato sauce, parmesan |
Quick Ways To Estimate Calories And Protein Without A Scale
Scales are great, yet you can still get close with a few visual cues. Use these as steady habits:
- Side dish portion: a loose handful of cooked sprouts is often a modest side, especially if paired with a bigger protein.
- Meal-prep portion: two loose handfuls of cooked sprouts is common for bowls and trays.
- Raw salad portion: a packed cup of shaved sprouts eats like a big salad base once you massage it with dressing.
When calories matter most, measure your cooking fat. When protein matters most, measure your protein food. Sprouts will take care of the “big plate” feeling.
Who Should Pay Extra Attention To Brussels Sprouts
Most people can eat Brussels sprouts without issues. Still, a few cases call for extra care:
- People taking blood-thinning medication: sprouts are high in vitamin K, so consistency in intake can matter.
- People with sensitive digestion: cruciferous vegetables can cause gas for some people, mainly in large portions.
If you fall into either group, the Harvard Nutrition Source page linked earlier gives useful context on sprouts as part of a varied vegetable rotation.
A Simple Way To Use This Article While You Meal Prep
If you want one repeatable system, do this:
- Pick your protein for the meal and portion it first.
- Pick your sprouts cooking method and measure the oil if you use it.
- Log sprouts using either the raw 100 g entry or the cooked cup entry, then stay consistent across the week.
- Adjust calories by changing the added fats, not by shrinking your vegetable portion.
That’s it. Sprouts stay low-calorie either way. Your pan choices decide the rest. Once you treat the sprouts as the base and your protein as the anchor, tracking gets calmer and meals taste better.
