4 min read

According to USDA data, one cup of cooked, shelled edamame can contain over 18 grams of protein. This makes young soybeans a serious contender in the quest to answer what's the highest protein veggie, especially for those prioritizing plant-based nutrition.

Quick Summary

This guide reveals the plant-based options that offer the most protein, with a detailed look at edamame, lentils, and peas. It compares nutritional values and explains how to get a complete set of essential amino acids from vegetable sources.

Key Points

  • Edamame is the Top Contender: Young soybeans, known as edamame, are the highest-protein vegetable, offering over 18g per cooked cup.

  • Soy is a Complete Protein: Edamame and other soy products contain all nine essential amino acids, making them a high-quality protein source.

  • Legumes are Protein Powerhouses: Other legumes like lentils (17.9g/cup) and green peas (8.6g/cup) are excellent sources of plant protein.

  • Variety Ensures Complete Amino Acids: Combining different plant proteins throughout the day is the best way to get all essential amino acids.

  • Don't Forget the Greens: Nutrient-dense greens like spinach and vegetables like potatoes and broccoli also contribute valuable protein to your daily intake.

  • Processing Can Boost Protein: Processed soy products like tofu and tempeh can provide a substantial protein boost in vegan and vegetarian meals.

What is the Highest Protein Veggie?

While the title of 'highest protein veggie' often goes to soybeans, particularly in their young form, edamame, it's important to understand the broader context. When discussing protein content in vegetables, it is common to consider legumes like lentils and peas alongside traditional greens, since they are all part of a robust plant-based diet. Edamame, which are immature soybeans, stand out by providing a high amount of protein per serving and are also considered a complete protein, containing all nine essential amino acids. A single cooked cup of shelled edamame packs approximately 18.4 grams of protein, a significant amount for a vegetable source.

Edamame: The Plant-Based Protein Powerhouse

Edamame's high protein content is a major reason for its popularity in vegetarian and vegan diets. Not only is it a potent protein source, but it also offers a balanced nutritional profile, rich in dietary fiber, vitamins, and minerals.

  • Rich in Nutrients: Edamame provides a wealth of folate, vitamin K, iron, and magnesium.
  • Fiber-Filled: The high fiber content in edamame helps with digestion and promotes a feeling of fullness.
  • Heart-Healthy: Studies suggest that the soy protein in edamame may help lower LDL ('bad') cholesterol levels.

The Contenders: Other Top High-Protein Vegetables

While edamame often takes the top spot, several other vegetables and legumes offer substantial protein. Varying your intake of these foods is key to getting a full range of nutrients.

Lentils: A Fiber and Protein-Packed Legume

Lentils are another incredible source of plant-based protein. A cooked cup of lentils delivers an impressive 17.9 grams of protein, in addition to being loaded with dietary fiber. Lentils are also a great source of iron and B vitamins, making them a fantastic, inexpensive base for soups, salads, and curries.

Green Peas: Small but Mighty

Often underestimated, green peas provide nearly 9 grams of protein per cooked cup. They are also a great source of vitamins C and K, as well as fiber. Peas are a versatile ingredient, perfect for adding a protein boost to stir-fries, pastas, or as a simple side dish.

Other Notable Veggies

Beyond the top-tier legumes, many other common vegetables contribute to your daily protein intake. Though they offer less per cup, a varied diet ensures you accumulate sufficient amounts throughout the day.

  • Spinach: A cup of cooked spinach provides around 6 grams of protein and is also an excellent source of iron and vitamins.
  • Lima Beans: One cup of cooked lima beans contains over 11 grams of protein.
  • Broccoli: This cruciferous vegetable contains about 4 grams of protein per cup when cooked.
  • Brussels Sprouts: Cooked Brussels sprouts offer over 5 grams of protein per cup.
  • Potatoes: A medium-sized baked potato with its skin provides about 4 grams of protein, along with significant amounts of Vitamin C and B-6.

High-Protein Veggie Comparison Table

Vegetable/Legume Protein (per cooked cup) Key Nutrients Additional Info
Edamame ~18.4 g Folate, Vitamin K, Fiber Complete protein source
Lentils ~17.9 g Iron, Folate, Fiber Excellent for soups and curries
Green Peas ~8.6 g Vitamin C, Vitamin K, Fiber Very versatile and adds color to dishes
Lima Beans ~11.6 g Potassium, Fiber, Iron Can be used in stews and salads
Spinach ~6 g Iron, Vitamins A & K Great for adding to sauces, stir-fries
Broccoli ~4 g Vitamins C & K, Fiber Excellent roasted or steamed

Making the Most of Your Plant-Based Protein

To ensure you are getting adequate protein from vegetables, variety is key. While edamame is a complete protein, many plant-based proteins are considered incomplete on their own. This means they don't contain all nine essential amino acids in sufficient quantities. However, by eating a variety of plant protein sources throughout the day, you can easily ensure your body receives all the necessary amino acids. The old idea of needing to combine specific incomplete proteins in a single meal has been debunked; what matters most is your overall intake over the course of a day. A simple meal of rice and beans, or a salad with lentils and chickpeas, can provide a great mix of amino acids.

For those seeking more information on maximizing plant-based protein, resources like Healthline's guide on "The 18 Best Protein Sources for Vegans and Vegetarians" offer a comprehensive look at both vegetables and other plant-based options. Incorporating processed soy products like tofu and tempeh, which are derived from mature soybeans, can also provide a substantial protein boost. Tofu, for example, is incredibly versatile and can be added to stir-fries, scrambles, and more.

Maximizing Protein in Meals

Here are a few simple ways to incorporate high-protein veggies into your meals:

  • Add edamame to salads, rice bowls, or snack on them steamed.
  • Use lentils as a base for hearty soups, stews, or veggie burgers.
  • Stir green peas into pasta dishes, risotto, or mash them for a side.
  • Sauté spinach and add it to omelets, curries, or pasta sauces.
  • Toss roasted Brussels sprouts with other vegetables for a high-protein side dish.

Conclusion

When it comes to answering what's the highest protein veggie, edamame is the clear winner, with a standout protein profile and status as a complete protein source. However, a truly healthy and balanced diet relies on variety. By incorporating a wide range of protein-rich vegetables like lentils, green peas, and nutrient-dense greens such as spinach and broccoli, you can easily meet your daily protein needs. Focus on diverse and colorful plant-based foods to build a robust and satisfying diet that offers a spectrum of essential amino acids and other vital nutrients.
