The 14 Best Vegan Protein Sources That Pack the Most Punch Per Calorie
Let’s be real: when you go vegan, everyone and their grandma suddenly becomes a nutrition expert. “But where do you get your protein?” they ask, eyeing your salad like it’s a crime scene. Here’s the truth—I’ve been vegan for years, and I’m still standing, stronger than ever, thanks to some plant-powered heavy hitters. Today, I’m spilling the beans (pun intended) on the 14 best vegan protein sources that deliver the most protein per calorie. These aren’t just nutritious—they’re lean, mean, protein machines. Whether you’re a gym rat, a busy parent, or just trying to impress your skeptical uncle at Thanksgiving, this list has you covered. Let’s dive in!
Why Protein Per Calorie Matters

Before we get to the good stuff, here’s why this matters. Protein keeps you full, builds muscle, and powers your day—but calories can sneak up fast. For vegans, finding foods that maximize protein without piling on carbs or fats is the holy grail. Spoiler: plants can do that better than you think. I’ve crunched the numbers (with help from trusty sources like the USDA and NutritionFacts.org) to rank these based on protein grams per 100 calories. Ready to rethink your plate? Let’s go!
1. Spirulina (20g Protein / 100 Calories)

Ever tried eating algae? No? Well, spirulina’s here to change your mind. This blue-green superfood boasts a jaw-dropping 20 grams of protein per 100 calories. At just 35 calories per tablespoon, it’s a powder you can toss into smoothies or oatmeal. Plus, it’s loaded with iron and antioxidants. I once tricked my boyfriend into thinking it was matcha—sneaky and nutritious!
2. Seitan (18.5g Protein / 100 Calories)

Say hello to the “wheat meat” that’ll make you forget chicken ever existed. Seitan delivers 18.5 grams of protein per 100 calories, with just 130 calories per 3.5-ounce serving. It’s made from vital wheat gluten, so it’s not for the gluten-free crew, but for everyone else? Stir-fry it, grill it, or shred it into tacos. My first attempt tasted like a chewy dream—carnivores, eat your heart out.
3. Nutritional Yeast (12.9g Protein / 100 Calories)

“Nooch” isn’t just for hipsters—it’s a protein-packed seasoning with 12.9 grams per 100 calories. Two tablespoons (60 calories) give you 8 grams of protein and a cheesy vibe without the dairy. Sprinkle it on popcorn or pasta, and thank me later. Fun fact: it’s also a B12 goldmine if you grab the fortified kind.
4. Tempeh (11.2g Protein / 100 Calories)

Fermented soybeans never sounded so sexy, right? Tempeh brings 11.2 grams of protein per 100 calories—about 19 grams in a 170-calorie serving. It’s nutty, firm, and perfect for crumbling into stir-fries. I once swapped it for bacon in a BLT, and my taste buds threw a party.
5. Tofu (10.5g Protein / 100 Calories)

The vegan OG, tofu, clocks in at 10.5 grams of protein per 100 calories. A 3-ounce serving (95 calories) nets you 10 grams. Grill it, scramble it, or blend it into smoothies—seriously, it’s the chameleon of food. My go-to? Crispy tofu nuggets that even my picky nephew couldn’t resist.
6. Edamame (9.5g Protein / 100 Calories)

These baby soybeans are snack goals: 9.5 grams of protein per 100 calories, or 11 grams per cup (118 calories). Steam ‘em, salt ‘em, and pop ‘em like nature’s candy. I keep a bag in my freezer for those “I need protein NOW” moments.
7. Lentils (9g Protein / 100 Calories)

Lentils are the unsung heroes of my kitchen—9 grams of protein per 100 calories, or 18 grams per cooked cup (200 calories). They’re cheap, hearty, and loaded with fiber. Pro tip: cook them in veggie broth for extra flavor. My lentil soup recipe? A winter game-changer.
8. Chickpeas (7.3g Protein / 100 Calories)

Hummus lovers, rejoice! Chickpeas offer 7.3 grams of protein per 100 calories—about 14 grams per cooked cup (164 calories). Roast them for a crunchy snack or blend them into dips. I once ate a whole bowl of roasted chickpeas watching Netflix. No regrets.
9. Black Beans (7g Protein / 100 Calories)

Black beans bring 7 grams of protein per 100 calories, or 15 grams per cooked cup (227 calories). They’re my burrito bowl staple—filling, versatile, and dirt-cheap. Bonus: they’ve got iron and magnesium to keep you rocking.
10. Hemp Seeds (6.7g Protein / 100 Calories)

Tiny but mighty, hemp seeds pack 6.7 grams of protein per 100 calories—10 grams per 3 tablespoons (150 calories). Sprinkle them on salads or yogurt for a nutty boost. And no, they won’t get you high—just healthy.
11. Quinoa (5.8g Protein / 100 Calories)

Quinoa’s not just a trendy grain—it’s got 5.8 grams of protein per 100 calories, or 8 grams per cooked cup (138 calories). It’s a complete protein, too, meaning all nine essential amino acids. Swap it for rice, and watch your meals level up.
12. Pumpkin Seeds (5.5g Protein / 100 Calories)

Pepitas, anyone? Pumpkin seeds deliver 5.5 grams of protein per 100 calories—7 grams per ounce (126 calories). Toast them for a snack or toss them in soups. I’m obsessed with their crunch—perfect for munching guilt-free.
13. Peas (5.4g Protein / 100 Calories)

Don’t sleep on peas! They’ve got 5.4 grams of protein per 100 calories, or 8 grams per cooked cup (148 calories). Sweet, green, and sneaky-high in protein, they’re my secret weapon in curries. Childhood flashbacks, but make it nutritious.
14. Spinach (5g Protein / 100 Calories)

Popeye was onto something. Spinach offers 5 grams of protein per 100 calories—3 grams per cooked cup (60 calories). It’s low-cal, iron-rich, and perfect for bulking up smoothies. I blend it into everything—because who doesn’t want to feel like a superhero?
