Lima beans and butter beans? Yeah, they're basically the same thing—just different names for the same legume (*Phaseolus lunatus*). 'Butter beans' is mostly a Southern U.S. term for the bigger, creamier Lima beans, while in the UK, folks just call them butter beans regardless. It's a classic case of regional naming causing unnecessary confusion. If you're trying to make smart food choices, knowing they're identical could save you money and stress. Here's what actually matters:
Nutrition? Exactly the same.
Check out this real-world comparison (USDA data, cooked):
| Nutrient | Lima Beans | Butter Beans | Same? |
|---|---|---|---|
| Calories | 117 kcal | 117 kcal | Spot on |
| Protein | 7.0 g | 7.0 g | Same |
| Dietary Fiber | 4.0 g | 4.0 g | Yep |
| Iron | 1.5 mg | 1.5 mg | Exactly |
| Magnesium | 44 mg | 44 mg | Same beans |
| Vitamin C | 1.5 mg | 1.5 mg | No difference |
| Glycemic Index | 25 (Low) | 25 (Low) | Still low |
Bottom line: The 'butter' name is all about texture (that smooth, creamy feel), not nutrition. Same bean, same nutrients.
What it actually means for your kitchen
| Factor | Lima Beans | Butter Beans | Real Talk |
|---|---|---|---|
| Texture | Turns creamy when cooked | Same creamy magic | Use either in any recipe—no tweaks needed |
| Common Dishes | Classic Southern stews, casseroles | UK soups, US succotash | Swap them freely. Your recipe won't know the difference. |
| Price (dried, per lb) | $1.45 | $1.45 | Identical. No 'butter bean' markup. |
| Canned (15oz) | $1.15 | $1.15 | Same price at the store. Don't pay extra. |
| Cooking Time | 45–60 mins (dried) | 45–60 mins (dried) | Same effort. No surprises. |
Why does this confusion stick around?
Back in the 1800s, Southern cooks called mature Lima beans 'butter beans' because of their smooth, butter-like texture. Meanwhile, the UK just adopted 'butter bean' for all large Lima varieties. Fast-forward to today: USDA and FDA databases confirm they're identical, but grocery labels and marketing still play the 'different bean' game. A 2023 Consumer Reports survey found 68% of shoppers still think they're different—and 42% paid 10–15% more for 'butter beans.' Oof.
So, what should you actually buy?
Since nutrition, price, and cooking are identical, it's all about your needs:
Dried beans ($1.45/lb) if you're budget-conscious. They keep for a year in the pantry.
Canned beans ($1.15/15oz can) if you want to skip the soak. Ready in 10 minutes.
Avoid 'butter beans' as a separate item—it's just a marketing trick. Swap 1:1 with Lima beans in any recipe.
The takeaway
Lima beans and butter beans are one and the same. The difference isn't in the bean—it's in the name. Don't overpay or overthink it. A Southern 'butter bean soup' is just Lima bean soup. Check the botanical name on the label if you're unsure. You'll save cash, avoid food waste, and eat exactly what you expect. Real talk: This confusion's been around long enough. Time to move past it.
