High protein vegetables are one of the best sources of protein and offer many other benefits of a plant-based diet. Although vegetables aren’t usually associated with protein, many are actually packed with it, particularly legumes, dark leafy greens, cruciferous vegetables, and certain roots and sprouts.
They’re nutrient-rich, high in fiber, and low in calories, making them great for supporting your muscles, keeping you full, maintaining a healthy weight, and promoting overall health. The protein values listed are approximate (per the USDA) for cooked vegetable amounts, unless otherwise specified. Below are the top 20 high protein vegetables from highest to lowest protein content based on a standard serving size.
