Per 100g, raw asparagus has about 2.2–2.9 grams of protein along with fiber, vitamins, and few calories.
Asparagus looks light on the plate, yet it gives a steady stream of plant protein, fiber, and micronutrients. When you understand asparagus protein per 100g, it becomes easier to plan plates, track macros, and build plant-forward meals that still feel satisfying.
Asparagus Protein Per 100G At A Glance
Most nutrient databases group green asparagus in the same ballpark. Data based on raw spears show around 2.2 to 2.9 grams of protein per 100 grams, along with low calories and little fat. Numbers shift a bit between brands, seasons, and measurement methods, which is why tables often list a range instead of a single figure.
USDA-linked tools and independent nutrition databases commonly place raw asparagus at about 20 to 27 calories per 100 grams, with protein providing a solid share of those calories. That means you get a modest protein boost with almost no calorie “penalty,” which works well for weight-conscious meal plans and higher volume plates.
| Nutrient | Amount Per 100g Raw Asparagus | Why It Matters |
|---|---|---|
| Protein | 2.2–2.9 g | Helps muscle repair and adds fullness with few calories. |
| Calories | 20–27 kcal | Makes asparagus easy to fit into calorie-controlled menus. |
| Carbohydrates | 3.9–4.1 g | Supplies a small amount of energy without heavy starch. |
| Dietary Fiber | 2.0–2.4 g | Helps with digestive comfort and longer-lasting fullness. |
| Total Fat | 0.1–0.2 g | Keeps total fat intake low while you add sauces or oils by choice. |
| Folate | ~50–60 mcg | Helps normal cell function and is valued in pregnancy diets. |
| Vitamin K | ~40–50 mcg | Plays a role in normal blood clotting and bone health. |
| Potassium | ~200–230 mg | Helps balance sodium intake and keeps blood pressure in a healthy range. |
Figures in this table pull from publicly available databases, including tools built on USDA FoodData Central and other nutrient datasets that track raw green asparagus. Values can shift with spear size, trimming, and how long bunches sit in storage, so treat them as ranges, not lab-perfect targets.
How Protein In Asparagus Adds Up Across Servings
Most people do not weigh asparagus on a kitchen scale each time they cook. Instead, they think in spears, cups, or a bundle grabbed from the produce shelf. The nice thing is that protein in asparagus scales in a straightforward way from the 100 gram benchmark.
From 100 Grams To Spears And Cups
A 100 gram serving usually lines up with about five to seven medium spears, or close to half a heaping cup once chopped. With that serving, you get roughly 2.2 to 2.9 grams of protein. A full cup of chopped asparagus can push protein closer to 3 grams, while a generous side plate built from eight to ten spears lands nearer to 4 grams.
When you see a macro plan that tracks vegetables loosely, you can treat asparagus like a low-calorie add-on that still contributes a little protein. It will not replace tofu or chicken on its own, yet it takes pressure off the main protein by adding a steady trickle in the background.
Asparagus Protein In Real Meals
Once you picture the asparagus protein number per 100 grams, menu math starts to feel easier. A grain bowl with 150 grams of asparagus mixed through warm quinoa already holds around 3 to 4 grams of asparagus-derived protein. A pasta dish with 120 grams of asparagus and a sprinkle of cheese moves closer to 3 grams from the vegetable alone, which stacks on top of protein from the pasta and dairy.
That might sound small, yet those grams add up across the day. If breakfast, lunch, and dinner each include a generous serving of vegetables like asparagus, peas, or broccoli, your plant protein intake creeps upward without any shakes or specialty products.
Nutrition Quality Beyond Protein
Protein numbers tell only part of the asparagus story. The vegetable brings fiber, folate, vitamin K, and a range of trace minerals that round out meals. This mix is one reason health writers and government resources often group asparagus with nutrient-dense vegetables suited to regular rotation.
The U.S. Food and Drug Administration lists asparagus in its raw vegetable nutrition tables, which show around 2 grams of protein in a 93 gram serving along with modest calories. That aligns with the 100 gram figures above and underlines how asparagus slips into many diets without pushing calorie totals upward.
Fiber, Satiety, And Blood Sugar
Fiber in asparagus slows digestion, which can steady appetite and blunt rapid swings in blood sugar when the vegetable sits beside refined carbs. The combination of modest protein and fiber gives asparagus more staying power than watery vegetables with almost no macronutrients at all.
For anyone trying to keep portions of meat in check, this mix matters. A plate that pairs a moderate amount of animal protein with a large serving of asparagus and other fibrous vegetables often feels more filling than a plate built mainly from white rice or bread.
Micronutrients That Travel With The Protein
Folate in asparagus helps normal red blood cell formation, while vitamin K takes care of clotting functions and bone-related processes. Minerals such as potassium, small amounts of iron, and trace zinc ride along. None of these change the protein count directly, yet they raise the overall nutrient “value per bite.”
Because asparagus is low in sodium and fat in its raw form, it gives home cooks freedom to add oil, nuts, seeds, or dressings for extra flavor and calories while still staying on track with broader health goals.
How Asparagus Protein Compares With Other Vegetables
On a per-100-gram basis, asparagus sits in the middle tier of vegetable protein sources. Peas, beans, and lentils carry far more protein per bite, while watery vegetables such as cucumber sit far lower. Leafy greens and brassicas often land in a similar range to asparagus.
Recent summaries of high-protein vegetables place green peas near 5.4 grams of protein per 100 grams, Brussels sprouts around 3.4 grams, kale about 3.3 grams, and asparagus near 2.9 grams. Broccoli hovers close to 2.8 grams, while cauliflower sits around 1.9 grams. These numbers shift slightly between datasets, yet the ranking pattern stays pretty stable.
Vegetable Protein Snapshot
The table below compares protein figures for raw or lightly cooked vegetables using a 100 gram baseline. Values combine data from public nutrition databases and summary articles that draw on government sources. Treat the numbers as guides, not promises, since soil, storage, and cooking time all nudge results one way or another.
| Food (Per 100g) | Protein | Notes |
|---|---|---|
| Green asparagus | 2.2–2.9 g | Low calorie, rich in folate and vitamin K. |
| Green peas | ~5.4 g | Higher protein legume often used as a side or mix-in. |
| Brussels sprouts | ~3.4 g | Dense, slightly bitter buds with solid fiber content. |
| Kale | ~3.3 g | Leafy green packed with vitamin A and vitamin K. |
| Broccoli | ~2.8 g | Common side vegetable with a protein level near asparagus. |
| Cauliflower | ~1.9 g | Mild flavor and flexible texture, lower in protein. |
| Edamame | ~11.9 g | Young soybeans that function more like a full protein source. |
With this context, asparagus earns its place as a useful side or component in a protein-aware meal, even if it cannot compete with edamame or lentils gram for gram. A plate that pairs asparagus with legumes, grains, nuts, or seeds ends up with a stronger protein profile than a plate built from starch and sauce alone.
Cooking Methods And Protein Retention
Cooking does not remove protein entirely, yet it changes water content and can shift measured values per 100 grams. Steaming or microwaving tends to preserve structure while keeping nutrient loss modest. Boiling, especially in a large pot of water for a long time, can leach out water-soluble vitamins, though protein itself largely stays put.
Grilling or roasting asparagus concentrates flavor and may slightly raise protein per 100 grams on paper as moisture leaves the spears. In practice, the total protein on your plate stays tied to the raw weight you started with. A 150 gram bundle of raw asparagus will deliver roughly the same protein whether you steam it briskly or roast it until the tips caramelize.
Seasoning Asparagus Without Losing The Health Angle
Since asparagus arrives almost fat-free, most of the calories from a side dish come from added oil, butter, cheese, or nuts. A drizzle of olive oil, a sprinkle of hard cheese, or a spoonful of toasted almonds brings flavor along with extra protein and healthy fats. Salt, lemon juice, garlic, and herbs layer more interest without shifting macros in any major way.
If sodium is a concern, lean on acids such as lemon juice or vinegar plus aromatics like garlic, chiles, and fresh herbs. This keeps the dish lively while protein, fiber, and micronutrient levels stay right where you expect them.
Practical Ways To Use Asparagus For Plant Protein
Asparagus alone will not meet daily protein targets for most people, yet it plays a helpful role inside mixed dishes. The goal is to use that 2.2 to 2.9 grams per 100 grams as one tile in a bigger pattern built from beans, grains, eggs, dairy, meat, or plant-based meat substitutes.
Building Balanced Plates
A simple dinner might combine grilled chicken, roasted potatoes, and 120 grams of asparagus. In that case, asparagus brings 2.5 to 3 grams of protein, extra fiber, and a stack of micronutrients, while chicken still carries the bulk of the protein. Swap the chicken for baked tofu or tempeh, and the asparagus protein per 100g figure keeps working in the background.
Lunch could be a grain bowl built from quinoa, chickpeas, roasted asparagus, and a yogurt-based dressing. Each scoop of asparagus nudges the protein count upward, so the final bowl lands well above what the grains and legumes provide alone.
Snacks And Light Dishes
Asparagus also fits into snacks and lighter meals. Chilled asparagus spears with hummus, asparagus frittata slices, or whole-grain toast topped with mashed avocado and sautéed asparagus all deliver small protein boosts driven partly by the vegetable itself.
Across a week of meals like this, the steady trickle of protein from asparagus helps overall intake goals, while the vegetable’s fiber and micronutrients keep plates colorful and varied.
