Mung Beans: Nutrition, Benefits & How to Cook Them

Mung beans are small green legumes used across Indian, Chinese and Southeast-Asian cuisine for centuries — and for the last decade, increasingly used in Canadian plant-based protein products as a less-allergenic alternative to soy. A cup of cooked mung beans is one of the most calorie-efficient ways to hit a meaningful protein-and-fibre target, and they cook faster than most other dried legumes.

What a cup of cooked mung beans actually delivers

Per 202 g (one cup, cooked, boiled, no salt): roughly 212 calories, 14 g protein, 15 g fibre, 39 g carbohydrate (24 g net), less than 1 g fat, 321 mg potassium, 97 mg magnesium, 2.8 mg iron and 321 µg folate.

That puts mung beans in the same tier as lentils for protein-per-calorie and slightly above black beans for fibre. Their glycemic load is in the low range (GL ~7 per cup), which makes them one of the more diabetes-friendly carbohydrate choices.

How they compare to lentils and chickpeas

Versus lentils: similar protein (14 vs 18 g/cup) and fibre (15 vs 16 g/cup), but lower in iron (2.8 vs 6.6 mg). Lentils are the iron champion of the legume world.

Versus chickpeas: mung beans have less starch (24 g vs 35 g net carbs) and slightly less protein (14 vs 14.5 g), but cook in 25 minutes versus chickpeas’ 90+ minutes from dry. They are the legume to use when you need fast.

Versus black beans: comparable across the board, but mung beans have a softer, more delicate flavour that takes on whatever spice profile you cook them in. Better in Asian dishes; black beans win in Mexican and Cuban cooking.

How to cook them (3 methods)

Stovetop, dry beans: 1 cup mung beans + 3 cups water, simmer 25–30 min until tender. No soaking required. They get to dal-soft consistency around 35 min.

Pressure cooker / Instant Pot: 1:2 ratio (beans to water), 8 minutes on high pressure, natural release. Comes out perfectly al-dente.

Sprouted (raw): rinse 1/2 cup beans, soak overnight, drain and rinse 2×/day for 2–3 days until 1–2 cm tails appear. Use in salads, banh mi, stir-fries.

Two reliable ways to use them

Indian moong dal: simmer cooked mung beans with turmeric, ginger, cumin, coriander and a splash of coconut milk. Serve over rice with a squeeze of lime.

Mung bean salad bowl: cooked mung beans, cherry tomatoes, cucumber, red onion, mint, lime, olive oil. 30 g protein per bowl, 12 g fibre, ready in 10 min if the beans are already cooked.

The bottom line

Mung beans are the best legume for weeknight cooking — fast, mild, high-protein and high-fibre, with a glycemic load low enough that they are routinely recommended for type 2 diabetes by Diabetes Canada. Buy them dried at any Indian or Asian grocery store for about $3/lb (versus $9/lb for the same protein in canned beans).
