No. Brussels sprouts offer modest protein—about 3–4 g per cup—so treat them as a nutrient-dense side, not a primary protein source.
Brussels sprouts bring fiber, vitamin C, and a little protein. Per cup, you’re looking at roughly 3 grams raw and 4 grams cooked. That’s handy for rounding out a plate, but it won’t carry your daily target by itself. This guide breaks down the numbers, shows how the protein compares to other foods, and gives smart pairing ideas so you can build a fuller, protein-steady meal.
Brussels Sprouts Protein At A Glance
Here are the most helpful serving sizes for everyday cooking and meal planning. The weight and protein figures are typical database values and line up with standard kitchen measures.
| Serving (Prep) | Protein (g) | Notes |
|---|---|---|
| 1 cup raw (~88 g) | ~3 | Common salad/shave portion; crisp bite. |
| 1 cup cooked, boiled (~156 g) | ~4 | Heavier cup after cooking; water content rises. |
| 100 g raw | ~3.4 | Good for label-style comparisons. |
| 100 g cooked, boiled | ~2.6 | Cooking softens texture; density shifts. |
What “Good Source” Means In Practical Terms
Nutrition labels use “% Daily Value” to frame amounts. On a 2,000-calorie label, the daily value for protein is 50 g. A food that gives ~10–19% of that per serving may be called a “good” source in casual speech, while 20%+ is often read as “high.” A cup of cooked Brussels sprouts delivers about 4 g—roughly 8% of the 50 g label target—so it’s on the lower side for protein, even though it shines for other nutrients.
Brussels Sprouts Protein Content And Daily Needs
Most adults can estimate daily protein needs by weight: about 0.8 g per kilogram. That’s roughly 50 g for a 140-pound person and ~70 g for a 200-pound person. In that context, a cup of cooked Brussels sprouts adds a small share toward the day’s total. You’ll meet fiber and micronutrient goals faster than protein goals with this vegetable.
How The Numbers Stack Up
Raw cups weigh less than cooked cups, which is why the cooked cup shows a slightly higher protein number per cup. On a per-100-gram basis, raw looks a bit higher than cooked because boiling adds water and changes density. None of that turns Brussels sprouts into a protein-heavy food; it just explains the small swings you’ll see across charts.
Amino Acids In Brussels Sprouts
The protein in Brussels sprouts includes essential amino acids, but not in the dense amounts you get from beans, soy, dairy, eggs, fish, or meat. For plant-forward eaters, that’s fine—variety across the day covers gaps. Pairing this vegetable with legumes or soy boosts the overall amino acid mix of the meal and drives total grams higher.
Smart Pairing Ideas That Raise Protein
- Sprouts + Lentils: Roast sprouts and toss with warm lentils, olive oil, lemon, and herbs. A cup of lentils packs far more protein than any vegetable.
- Sprouts + Tofu Or Tempeh: Stir-fry halved sprouts with cubes of tofu or strips of tempeh; finish with tamari and sesame.
- Sprouts + Eggs: Shred and sauté, then fold into an omelet or frittata for an easy brunch plate.
- Sprouts + Grains And Nuts: Try a farro bowl with roasted sprouts, toasted walnuts, and a yogurt-tahini drizzle.
Nutrient Perks Beyond Protein
Brussels sprouts shine for vitamin K, vitamin C, folate, fiber, and plant compounds found in the cabbage family. You get steady fullness from fiber, plus a bright, slightly sweet base that fits many kitchens—sheet-pan roasts, skillets, or raw shaved salads.
Cooking Methods That Keep Value
High heat roasting adds browning and keeps texture. Quick sautéing works for sliced or shaved sprouts. Boiling is common, then finishing in a pan with a brief sear adds flavor without long extra time. Aim for tender with a bit of bite.
How Brussels Sprouts Compare With Other Veggie Proteins
Vegetables aren’t the top tier for protein, but some pull more weight than others. The quick scan below uses typical cooked portions.
| Food (Cooked) | Typical Serving | Protein (g) |
|---|---|---|
| Brussels sprouts, boiled | 1 cup | ~4 |
| Broccoli, boiled | 1 cup | ~3–4 |
| Spinach, boiled | 1 cup | ~5 |
| Green peas, boiled | 1 cup | ~8–9 |
| Edamame (shelled), cooked | 1 cup | ~16–18 |
When Brussels Sprouts Make Sense For Protein Goals
Use them to add grams, not to anchor a protein-targeted meal. If your day calls for 60–80 g, two cups of cooked sprouts only bring 8 g. Pair with a protein base—beans, tofu, fish, dairy, eggs, lean meats—or build grain-and-legume combos and let sprouts deliver fiber and flavor around that core.
Plate Templates That Work
- High-Protein Vegetarian: Bowl of quinoa + edamame + roasted sprouts + pumpkin seeds; lemon-tahini sauce.
- Quick Omnivore: Pan-seared salmon or chicken + garlic-roasted sprouts + yogurt-herb sauce.
- Lunch Prep: Whole-wheat pasta salad with sprouts, chickpeas, olives, and a light vinaigrette.
Raw Versus Cooked: Does It Matter For Protein?
Cup-for-cup, the cooked portion reads higher since more sprouts fit in the cup after cooking. Per 100 g, the raw number looks a touch higher than the boiled figure because boiling pulls in water and spreads the same protein across more weight. The real-world takeaway: the protein difference isn’t large; choose the prep that fits your meal.
Trusted Numbers You Can Use
For nutrient data, an easy reference is the raw Brussels sprouts profile and its cooked counterpart on MyFoodData, which compiles entries from the U.S. Department of Agriculture’s database. For daily protein targets by body weight, see Harvard’s overview of protein recommendations. These two resources keep your planning grounded in measured values and mainstream guidance.
Buying, Storing, And Quick Prep Tips
Pick
Choose firm, compact heads with bright green leaves. Smaller sprouts tend to cook evenly and taste sweeter.
Store
Keep unwashed sprouts in a breathable bag in the fridge. Use within a week for peak flavor and texture.
Prep
Trim the stem end, peel any loose outer leaves, and halve for faster, even cooking. For salads, shave thinly across the grain; salt and rest a few minutes, then dress.
Ways To Add More Protein To A Brussels Sprouts Dish
Plant-Based Boosters
- Legumes: Chickpeas, white beans, or lentils stirred into roasted sprouts.
- Soy: Tofu sheet-pan bake with sprouts; tempeh crumbles browned with smoked paprika.
- Nuts And Seeds: Toasted almonds, walnuts, or pumpkin seeds for crunch and a small protein bump.
Animal-Based Boosters
- Eggs: Top a warm sprout hash with a soft-yolk egg.
- Dairy: Crumbled feta, shaved Parmesan, or a yogurt-herb dollop on roasted sprouts.
- Seafood Or Poultry: Pair a fillet or a grilled chicken portion with a hearty sprout side.
Answer You Can Act On
Brussels sprouts add a little protein and a lot of fiber and vitamins. They’re not a stand-alone protein source, yet they help build a balanced plate when you add beans, soy, eggs, dairy, fish, or lean meats. Use the tables above to portion smartly, then round out the meal with a strong protein partner.
