String beans aren’t high in protein—one cup has around 2 g, so count string beans as a vegetable, not a protein source.
If you’re scanning dinner sides for extra protein, string beans (green beans, snap beans) won’t move the needle much on their own. They shine for fiber, vitamins, and crunch, but their protein per serving lands in the “low” range. That doesn’t make them a weak pick—just a different job on the plate. Below you’ll see exactly how much protein string beans deliver, how that compares with other foods, and easy ways to pair them so your meal hits a satisfying protein target.
Are String Beans High In Protein? Facts By Serving
Raw green beans provide about 1.8 grams of protein per 100 grams. One cup of raw green beans usually weighs ~100 grams, which means that cup also delivers around 1.8–2 grams of protein. Cooked green beans are similar by weight, so the math stays close. In short, the protein count is small per cup.
Protein In String Beans By Common Serving
| Form | Typical Serving | Protein (g) |
|---|---|---|
| Raw string beans | 100 g | ~1.8 |
| Raw string beans | 1 cup (chopped) | ~1.8–2.0 |
| Cooked, boiled, drained | 100 g | ~1.9 |
| Cooked, boiled, drained | 1 cup | ~2.0 |
| Canned, drained | 1 cup | ~1.8–2.0 |
| Frozen, unprepared | 1 cup | ~1.7–2.0 |
| French-cut style | 1 cup | ~1.8–2.0 |
These numbers come from national nutrient datasets. For a line-by-line breakdown, see green beans in MyFoodData’s USDA-based entry for raw green beans and the matching page for cooked green beans (boiled, drained). Both draw from USDA FoodData Central and reflect standard household servings.
What “High Protein” Usually Means
When people say a food is “high in protein,” they typically mean it gives a large dose per calorie or per serving. Lean meats, eggs, yogurt, firm tofu, tempeh, seitan, edamame, and most cooked dry beans sit near the top. Green beans are a non-starchy vegetable with a light protein contribution. They’re great in mixed dishes, salads, and sides, but they aren’t a stand-alone protein.
Plant-forward plates still hit strong protein totals by mixing foods wisely. If you’re curbing red meat or just want more plants, building your plate around legumes, soy foods, dairy, grains, nuts, and seeds works well. Harvard’s Nutrition Source offers a clear overview of protein choices and portion ideas.
Are Green Beans High In Protein: What A Cup Gives
Here’s the practical read: you’ll get around 2 grams of protein from one cup of green beans. That’s a small assist toward a typical meal target of 20–35 grams. Still worth eating? Absolutely—fiber, vitamin K, vitamin C, and a crisp texture make them a side you’ll keep around. Just plan a primary protein next to them.
How To Turn A String Bean Side Into A Protein-Savvy Plate
Pair string beans with one anchor protein and, if you like, a small booster. The anchor is the workhorse (tofu, tempeh, fish, chicken, eggs, lentils). The booster adds extra grams without stealing the spotlight (nuts, seeds, cheese, edamame, yogurt-based dips). This setup keeps dinner balanced while letting green beans bring color and crunch.
Easy Pairings That Work
- Skillet beans + sliced almonds + lemon: a quick side where almonds add a few grams.
- Green bean, tuna, and potato salad: classic niçoise vibes with a full protein anchor.
- Sesame-garlic beans with tofu: cubes of pan-seared firm tofu carry the protein load.
- Sheet-pan beans with chicken thighs: one pan, simple spices, complete meal.
- Green beans with egg and pesto: a seven-minute egg brings 6 grams; pesto adds flavor and a bit more from nuts and cheese.
Cooking Details That Change Little (But Help Flavor)
Protein in string beans doesn’t swing much with boiling vs. steaming vs. sautéing. The number per 100 grams stays near 2 grams. What does change is water and texture: a quick blanch keeps snap; a sauté adds browning; a steam keeps it clean for salads. Season with salt, acid (lemon or vinegar), and a little fat to carry flavor.
How String Beans Compare With True Protein Staples
To set expectations, check green beans against classic protein picks. This is where you can see why they’re a side, not the centerpiece for protein. Use the list below when planning menus that need a clear protein anchor.
Protein Snapshot: Green Beans vs. Common Protein Foods
| Food | Typical Serving | Protein (g) |
|---|---|---|
| Green beans | 1 cup (raw or cooked) | ~2 |
| Lentils, cooked | 1 cup | ~18 |
| Black beans, cooked | 1 cup | ~15 |
| Edamame | 1 cup | ~17–18 |
| Firm tofu | 1/2 cup | ~10 |
| Chicken breast, cooked | 3 oz | ~26 |
| Egg | 1 large | ~6 |
| Greek yogurt (plain) | 3/4 cup (170 g) | ~15–17 |

Ways To Get More Protein While Keeping The Beans
Think of string beans as the team player that helps the plate feel fresh. Then let one of these ideas carry the protein:
Plant-Forward Ideas
- Green bean and lentil bowl: warm lentils seasoned with garlic and olive oil, beans for crunch, toasted walnuts for a small bump.
- Stir-fry with tofu or tempeh: cubes seared until golden, beans added late to keep snap.
- Pasta with beans and edamame: edamame boosts protein while beans and cherry tomatoes add texture.
Animal-Based Anchors
- Salmon with garlicky beans: seamonster-level flavor, packed plate, simple pan sauce.
- Roast chicken with lemony beans: sheet-pan juices double as dressing.
- Steak strips over bean salad: a small portion still drives protein up.
Are String Beans High In Protein? Two Clear Takeaways
First: the answer is “no” when judged against beans like lentils or soy, dairy, eggs, or meat. One cup brings around 2 grams.
Second: they still earn a spot. Fiber, vitamins, and easy prep make them a side you’ll repeat; just add an anchor protein to hit your goal.
Buying, Storing, And Prepping For Best Results
What To Look For
- Color that’s bright with a firm snap when bent.
- Pods that are thin to medium; oversized pods can eat a bit tough.
- Minimal blemishes or soft spots.
Storage Tips
- Refrigerate unwashed in a breathable bag; use within 3–5 days.
- Wash right before cooking to keep texture.
- Blanch and freeze if you won’t finish the bag soon.
Cooking Methods That Keep Snap
- Blanch and shock: 2–3 minutes in salted water, then ice bath, then finish in a pan with oil, garlic, and lemon.
- Stir-fry: hot pan, small oil, quick toss until blistered spots form.
- Roast: toss with oil and salt; bake at 220°C/425°F for 12–15 minutes until browned in places.
- Steam: 5–7 minutes until tender-crisp, then dress while warm.
Label Reading: What Numbers Matter On Packaged Beans
Plain frozen or canned beans should list only beans, water, and salt. Draining and rinsing canned beans trims sodium. The protein line will look small; rely on that anchor food to reach your target for the meal.
Common Questions, Answered Quickly
Do I Need To Combine Beans And Grains At One Meal?
No. Eating varied protein sources across the day covers amino acids nicely. Mix and match foods you enjoy and let totals add up across meals.
Can I Count String Beans As My Protein Choice?
Use them as a veggie. Bring in tofu, tempeh, eggs, fish, poultry, meat, dairy, or higher-protein legumes to fill the role of the protein anchor.
What’s A Simple Protein Goal For Dinner?
Many people feel satisfied with 20–35 grams at a main meal. Pick an anchor, add your beans and a grain or potato, and you’ll land in that range with ease.
