No, Brussels sprouts are a low-protein vegetable at ~3–4 g per serving; great for variety, not a primary protein source.
Curious about where this crunchy crucifer fits in your protein plan? You’re not alone. Brussels sprouts bring fiber, vitamin C, vitamin K, and a mild, nutty bite. Protein is there, just not in big numbers. This guide breaks down the actual grams by serving size, how cooking changes the count, how they stack up against other foods, and easy ways to pair them with stronger protein so your plate stays balanced.
Quick Protein Facts You Can Use
Across common portions, you’ll usually see about 3–4 grams of protein. That lands Brussels sprouts in the “supporting cast” for protein, not the star. Here’s a clear view by serving size.
| Serving | Protein (g) | Notes |
|---|---|---|
| 100 g raw | ~3.4 g | Baseline lab value for uncooked sprouts. |
| 1 cup raw (shredded) | ~3.0 g | Volume can vary with cut size. |
| 1 cup cooked (boiled/steamed) | ~4.0 g | Cooking softens tissue; a cup holds more mass. |
| 4–5 medium sprouts | ~2.5–3.5 g | Count shifts with sprout size. |
Why The Numbers Look “Modest”
Vegetables tend to be water-rich and calorie-light. That’s true for Brussels sprouts, so protein density stays low compared with beans, soy foods, dairy, or meat. You’ll still get building blocks for muscles and enzymes, just in smaller doses per bite.
Protein In Brussels Sprouts Compared To Other Foods
When you match them against legume and grain staples—or against animal foods—the gap becomes clear. This section shows how much protein you get for the same 100 g portion, which keeps the comparison fair.
Keep in mind that daily protein targets for many adults start near 50 g (the label Daily Value used on packages) and can rise with body size and activity. You’ll reach that faster by pairing sprouts with stronger protein at meals.
How Cooking Affects The Count
Cooked cups often show slightly higher grams than raw cups because heat softens the leaves and packs more vegetable mass into the same volume. Per 100 g, raw and cooked are similar; per cup, cooked tends to edge up.
Amino Acid Quality In Context
Protein isn’t only about grams. The amino acid mix and digestibility matter. Plant proteins can be limited in one or more essential amino acids. That doesn’t make them “bad”; it just means variety across the day helps. Pairing sprouts with beans, tofu, lentils, eggs, dairy, or grains rounds out the profile.
What Counts As “High Protein” On A Plate?
Labels use 10% of the Daily Value per serving to call a food a “good source” of protein and 20% to call it “excellent.” With a Daily Value of 50 g, a serving would need 5 g for “good” and 10 g for “excellent.” A cup of cooked Brussels sprouts sits near 4 g, so it falls shy of “good source.” That’s why most meal plans treat sprouts as a nutrient-dense vegetable side, not as the main protein anchor.
Practical Ways To Get Enough Protein With Sprouts
You don’t need to chase numbers in one food. Build meals that add up. These easy pairings keep flavor high and totals on track:
- Sheet-Pan Dinner: Toss halved sprouts with olive oil and spices. Roast with chicken thighs or tofu cubes. Add a grain to catch the juices.
- High-Protein Pasta: Sauté shredded sprouts with garlic. Fold into chickpea pasta with lemon, pepper, and grated cheese or a creamy tahini sauce.
- Power Bowl: Layer warm sprouts over quinoa or farro. Top with soft-boiled eggs, salmon, or tempeh and a mustard-yogurt drizzle.
- Skillet Hash: Pan-sear diced sprouts with potatoes and onions. Finish with beans and fried eggs for a complete, hearty plate.
Portion Guide For Common Goals
Here’s a simple way to think about it. If your target is near 50 g a day, a cup of cooked Brussels sprouts covers roughly 8% of that number. Two cups land near 16%. That still leaves plenty of room for protein-strong picks at breakfast, lunch, or dinner.
Who Benefits From More Protein?
Strength athletes, older adults, people on energy-restricted diets, and anyone recovering from injury may aim higher than the label baseline. In those cases, Brussels sprouts stay in the rotation for micronutrients and fiber, while the main protein load comes from foods with higher density.
Nutrition Perks Beyond Protein
Sprouts pack vitamin C and vitamin K, plus fiber for fullness and gut health. That combo supports day-to-day wellbeing and helps meals feel satisfying even when calories stay modest.
Smart Shopping And Prep Tips
- Pick Firm Heads: Tight, bright leaves signal freshness.
- Use A Hot Oven: Roast at 220 °C (425 °F) until edges brown; that’s where the flavor lives.
- Slice For Speed: Shredded sprouts sauté fast and take on sauces nicely.
- Salt Late: Season near the end to keep bites crisp.
How They Stack Up By The Numbers
This table lines up 100-gram portions so you can compare protein density at a glance. Use it to plan sides around your main protein.

| Broccoli, raw | ~2.8 | ~34 kcal |
| Green peas, cooked | ~5.4 | ~84 kcal |
| Lentils, cooked | ~9.0 | ~116 kcal |
| Firm tofu | ~8.0 | ~76 kcal |
| Chicken breast, cooked | ~31 | ~165 kcal |
| Egg, whole | ~13 | ~155 kcal |

Meal-Builder: Turn Sprouts Into A Protein-Balanced Plate
Roasted Sprouts + Protein Pick
Roast a tray of halved sprouts with oil, salt, pepper, and paprika. Serve beside baked salmon, grilled tempeh, or roast chicken. Add quinoa or bulgur for texture and extra protein.
Shredded Sprouts Pasta
Sauté garlic in olive oil, add shredded sprouts, and cook until bright and tender. Toss with chickpea or lentil pasta, lemon zest, Parmesan or nutritional yeast, and a handful of toasted nuts.
Sprout And Bean Skillet
Brown diced sprouts with onion. Stir in white beans, a spoon of Dijon, and a splash of broth. Finish with herbs and a fried egg on top.
Label Math: What “Good Source” Would Take
If a serving hits 5 g protein, it can be called a “good source.” A typical cup of cooked Brussels sprouts sits near 4 g, so you’d need a larger portion or a partner food to reach that label claim. That’s why pairing works so well: two cups of sprouts plus 100 g of tofu jumps past 20 g protein without losing the vegetable base you want.
Key Takeaways
- Per 100 g, Brussels sprouts give roughly 3–4 g protein; per cooked cup, around 4 g.
- They shine for fiber, vitamin C, and vitamin K; treat them as a nutrient-dense side.
- Combine with beans, tofu, eggs, dairy, fish, or chicken for protein-strong meals.
- Aim for steady protein across meals; sprouts contribute, yet bigger lifts come from higher-density foods.
