Let's be honest, lima beans don't get a lot of love. Often remembered as a mushy, bland side dish from childhood, the dried version is a completely different animal. When cooked from scratch, they're creamy, nutty, and one of the most nutritionally impressive foods in the pantry. They are absolutely loaded with plant protein and gut-friendly fiber, delivering slow-burning energy that keeps you full for hours. It's time for a reappraisal.
↑ Dried lima beans — a fantastic source of plant protein and fibre.
The underrated legume
Also known as butter beans for their starchy, buttery texture, lima beans are a seriously underrated pantry staple. They're inexpensive, versatile, and from a nutritional standpoint, they punch well above their weight. The key is to buy them dried and cook them yourself. A long soak and a gentle simmer transforms them into something creamy and delicious, ready for soups, stews, salads, or simple mashes.
The numbers are what really tell the story: for a plant food, the protein is sky-high, and the fibre content is simply off the charts. This combination is the magic formula for stable blood sugar and long-lasting fullness.
IN ONE LINE
Packed with protein and fibre, lima beans are a low-GI, heart-healthy food that keeps you full for hours. They are one of the most satisfying plant-based foods you can eat.
Lima bean nutrition facts
Here’s the nutritional breakdown for a 100-gram serving of dried lima beans (which cooks up to about 2.5 to 3 cups).
Two numbers leap out: 19 grams of fiber and 21.5 grams of protein. That's more than two-thirds of your daily fiber and over 40% of your protein in a single 100g dry serving. It's this one-two punch of fiber and protein that makes them such a profoundly healthy and satisfying food. The fat content is negligible.
Lima beans' glycemic index
Glycemic index (GI) tells us how quickly a food raises blood sugar. While there isn't an official, universally agreed-upon GI value for dried lima beans, their composition makes the verdict clear. With so much fiber and protein packed into their carbohydrate structure, the digestion and absorption of their carbs is very slow. They are firmly a low-glycemic food, making them an all-star for anyone managing blood sugar.

How to cook them right
Getting the best from dried lima beans is simple, but a few non-negotiable steps make all the difference between creamy perfection and a disappointing meal.
01
Soak them overnight.
Cover the dried beans with plenty of water and let them sit for at least 8 hours, or overnight. This rehydrates them, shortens cooking time, and makes them easier to digest.
02
Cook them gently.
Drain the soaked beans, cover with fresh water in a pot, and bring to a simmer. Don't boil them aggressively. A gentle simmer for 60-90 minutes is perfect.
03
Salt at the end.
Adding salt or acidic ingredients like tomatoes too early can make the bean skins tough. Season them in the last 10-15 minutes of cooking.
04
Cook them thoroughly.
Like all beans, lima beans contain lectins that are destroyed by proper cooking. They're ready when they are completely tender and creamy.

FREQUENTLY ASKED QUESTIONS
Frequently asked questions
Are lima beans good for people with diabetes?
Yes, they are an excellent food for diabetes management. Their high fiber and protein content, combined with a low glycemic index, helps prevent blood sugar spikes and promotes stable energy.
Do lima beans help you lose weight?
They can be a great tool for weight management. The powerful combination of fiber and protein makes them extremely filling, which can help you feel satisfied on fewer calories and reduce overall hunger.
Are lima beans a complete protein?
By themselves, lima beans are not a complete protein, as they are low in the amino acid methionine. However, when paired with a whole grain like brown rice or whole wheat bread, they form a complete protein that provides all the essential amino acids your body needs.
Are canned lima beans as healthy as dried?
Canned lima beans are still nutritious but can be very high in added sodium. If you use canned, look for 'no salt added' versions or rinse them thoroughly under water to wash away some of the excess salt. Dried beans that you cook yourself give you complete control over the salt content.
