Vegetables that actually add protein
Written by The Kalcule Team · Last updated 18 augustus 2026
Peas, corn, broccoli, spinach and potatoes add useful grams, especially in large volumes. Legumes are the real plant-protein staples and sit in a grey zone between vegetable and protein food.
Legumes first
Lentils, beans, chickpeas and soy are how plant-based eaters hit targets. Green vegetables help but are supporting actors.
Volume versus density
A kilogram of boiled broccoli is a lot of chewing for the protein you get. Combine vegetables with tofu, tempeh, dairy or eggs if you use them.
Frozen is fine
Frozen peas and spinach are cheap protein-plus-micronutrient add-ins for soups, rice and eggs.
Still count calories
Starchy vegetables are not free. The calorie calculator still applies. Protein vegetables are not a loophole.
