High-Protein Vegetables: What Actually Has Protein

No vegetable is going to carry a meal’s protein the way meat, eggs, or dairy can. But some vegetables genuinely have more protein than people expect, and it’s worth knowing which ones those are before you assume a side dish is contributing nothing. Numbers below are per typical serving, from USDA FoodData Central.

The vegetables that actually count

• Edamame (1 cup): about 18g protein. This one’s really a legume, not a vegetable in the strict sense, but it’s sold and cooked like one, so it belongs on this list.
• Green peas (1 cup): about 8g protein
• Brussels sprouts (1 cup, raw): about 3g protein
• Broccoli (1 cup, raw): about 3g protein
• Spinach (1 cup, raw): about 1g protein, but it packs down so much that a cooked cup is closer to 5g
• Asparagus (1 cup, raw): about 3g protein
• Mushrooms (1 cup, raw): about 2g protein
• Snap peas (1 cup, raw): about 3g protein

The vegetables that don’t

Zucchini, cauliflower, bell peppers, celery, cabbage, and carrots are all real, useful vegetables in high-protein cooking, they hold volume, add fiber, and round out a plate, but none of them carry more than a gram or two of protein per serving. That’s not a knock on them; it’s just not their job. The protein in a meal built around these comes from what’s served alongside them, not the vegetable itself.

Why this distinction matters for cooking

A recipe built around zucchini noodles or cauliflower rice gets its protein number from the meat, seafood, or dairy in the dish, not from the vegetable swap. That’s true of the shrimp and cauliflower rice stir-fry and the garlic butter steak bites here: the vegetable is doing volume and fiber, the protein source is doing the protein.

Edamame is the one real exception on this list. If you want a vegetable that’s pulling real protein weight on its own, that’s the one to reach for, tossed into a stir-fry, eaten steamed and salted, or added to a grain bowl.

This is food information, not a recommendation for how much of any of these you personally need.
