Ever wonder why some bean soups look impressive and taste amazing while yours just looks like baby food? I used to avoid lima beans completely until I discovered these gorgeous giant lima bean soup varieties—sometimes called butter beans or gigantes—at my local international market. Now my family devours this creamy, substantial bowl at least twice a month, and I’m pretty sure my Greek-food-loving friends think I’ve been secretly studying Mediterranean cooking (if only they knew the whole thing is just patience, good beans, and letting them simmer into buttery perfection).
Here’s the Thing About This Recipe
What makes this giant lima bean soup work is the unexpected creaminess of properly cooked giant lima beans—those huge, flat white beans that are nothing like the sad little green limas from cafeteria nightmares. I learned the hard way that giant lima beans need overnight soaking and long, gentle simmering to transform from rock-hard nuggets into the creamiest, most buttery beans you’ve ever tasted. The secret to authentic comfort here is patient cooking that lets the beans break down slightly and release their natural starches, creating a soup that’s thick and velvety without any cream or blending. It’s honestly that simple—soak the beans, build a flavorful aromatic base, then let time work its magic.
What You’ll Need (And My Shopping Tips)
Good dried giant lima beans are worth seeking out at international markets, Mediterranean groceries, or online—look for large, flat white beans labeled “giant lima beans,” “butter beans,” or “gigantes.” Don’t cheap out on the vegetable broth either; I always grab the low-sodium version so I can control the seasoning myself (I learned this after making one batch so salty we needed extra water to dilute it). Fresh vegetables matter here, so pick carrots and celery that actually snap when you bend them, and grab onions and garlic that feel firm without any soft spots. I always grab an extra carrot because someone inevitably wants more vegetables floating in their bowl. Before soaking, spread your beans on a light-colored plate and pick through them for any small stones or shriveled beans—happens more than I’d like to admit with dried legumes. For the best guide to lima beans and their varieties, these protein-packed legumes have been cultivated in Central and South America for over 7,000 years and come in sizes from tiny baby limas to these gorgeous giant varieties that are prized across Mediterranean and South American cuisines.
Let’s Make This Together
Start the night before by rinsing those giant lima beans under cold water in a colander, then put them in a large bowl and cover with at least 3 inches of cold water—they’ll double in size as they soak. Let them sit on the counter overnight or for at least 8 hours. Here’s where I used to mess up: I’d skip the soaking thinking I could just cook them longer, but unsoaked giant limas take forever to soften and often stay tough in the center.
The next day, heat that olive oil in a large pot over medium heat. Toss in the chopped onion, diced carrots, and chopped celery, and sauté for about 5 minutes until they start to soften and smell amazing. Add the minced garlic, dried thyme, and dried rosemary directly to the pot. Cook for just one more minute, stirring constantly—you want the garlic fragrant and the herbs toasted, but not burned.
Now drain your soaked lima beans (discard that soaking water) and add them to the pot with all those aromatic vegetables. Pour in the vegetable broth and crank the heat to high to bring everything to a rolling boil. Once it’s boiling vigorously, immediately reduce the heat to low, cover the pot with a lid, and let this beauty simmer gently for 1.5 to 2 hours. Here’s my secret: I check the beans starting at 1.5 hours because every batch of dried beans cooks differently depending on age. You want them creamy and tender enough to smash easily between your fingers, with some beans breaking down slightly to naturally thicken the soup.
Once your beans are perfectly tender and the soup has thickened beautifully, season generously with salt and pepper—taste as you go because beans are starch bombs that need serious seasoning to really shine. If you’re looking for another substantial bean soup option, this Greek white bean soup makes a perfect companion recipe celebrating Mediterranean bean traditions.
Common Oops Moments (And How to Fix Them)
Beans still rock-hard after 2 hours? You probably got an older batch of dried beans that needs more time, or you forgot to soak them overnight—just keep simmering and checking every 20 minutes. In reality, I’ve learned to always budget extra time when cooking dried beans because you never know how long they’ve been sitting in storage. Beans exploding and falling apart into complete mush? Your heat was too high during the simmer—giant lima bean soup needs gentle, patient cooking at a true low bubble, not an aggressive boil. If your soup tastes flat and boring (and it might at first), you probably needed way more salt and maybe a splash of lemon juice or vinegar at the end. I always keep these nearby now because beans need acid to really pop with flavor. Soup too thin and watery? Let it simmer uncovered for the last 30 minutes to concentrate the flavors and let more beans break down naturally, or gently mash some beans against the side of the pot to thicken it.
When I’m Feeling Creative
Around the fall months, I’ll add a cup of diced tomatoes along with the broth to make this giant lima bean soup even richer and more substantial—it transforms into almost a Greek-style gigantes plaki soup. When I’m feeling fancy, I’ll top each bowl with a generous drizzle of good olive oil, crumbled feta cheese, and extra fresh herbs. Smoky Bean Soup: Add 1 teaspoon smoked paprika with the herbs for depth. Mediterranean Style: Finish with lemon juice, good olive oil, fresh dill, and crumbled feta. Spicy Version: Add diced jalapeños or red pepper flakes with the garlic for heat. Creamy Variation: Stir in 1/2 cup coconut milk during the last 10 minutes for richness without dairy.
Why This Recipe Works So Well
This giant lima bean soup stands out because it celebrates heirloom bean varieties that have been cultivated across the Americas and adopted enthusiastically by Mediterranean cuisines, particularly Greek cooking where gigantes beans are a staple. These gorgeous large lima beans with their buttery texture transform a simple soup into something genuinely satisfying and nutritionally impressive without any fancy techniques. Unlike smaller beans that can turn mushy, giant limas maintain their shape while developing the creamiest interior texture that makes this soup feel indulgent. The long, slow simmer allows some beans to break down and naturally thicken the broth while others stay intact, creating interesting texture in every spoonful.
Things People Ask Me About This Recipe
Can I make this giant lima bean soup ahead of time?
Absolutely—this soup is actually one of those magical dishes that tastes even better the next day as the flavors continue to develop and the beans absorb more seasoning. Store it in an airtight container in the fridge for up to 5 days. The soup will thicken considerably as it sits, so you might need to add extra broth when reheating.
Do I really need to soak the giant lima beans overnight?
For giant lima beans, yes—overnight soaking significantly reduces cooking time and helps them cook more evenly. You can do a quick-soak method (bring beans and water to a boil, turn off heat, let sit 1 hour) but overnight soaking is better for these large beans and makes them easier to digest.
What if I can’t find giant lima beans for this soup?
Regular large lima beans or butter beans work perfectly fine—they’re often the same thing just marketed differently. You could also use cannellini beans or great northern beans, though the texture will be slightly different since they’re not as naturally creamy as giant limas.
Can I freeze this bean soup?
Yes, this soup freezes beautifully for up to 3 months. Let it cool completely, then portion into freezer-safe containers leaving about an inch of space at the top for expansion. Thaw overnight in the fridge and reheat gently on the stovetop, adding extra broth if needed.
Is this giant lima bean soup vegan?
It is! This soup is naturally plant-based since it uses vegetable broth and contains no animal products. It’s also high in protein from the beans, making it a satisfying vegan meal option that doesn’t need meat to feel filling.
How can I make this soup creamier without dairy?
The beans themselves create natural creaminess as they break down during cooking. You can also partially blend the soup with an immersion blender (blend about 1/3 of it), mash more beans against the side of the pot, or stir in coconut milk during the last 10 minutes for extra richness.
Before You Head to the Kitchen
I couldn’t resist sharing this giant lima bean soup because it proves that beans can be both beautiful and delicious when you seek out quality varieties and give them the time and respect they deserve. The best soup nights are when everyone’s surprised by how creamy and satisfying a simple pot of beans can be, and nobody misses the meat or heavy cream. Give this one a try—your body will thank you for all that plant-based protein and fiber.

Notes:
- Seriously, don’t skip the overnight soaking—giant lima beans need it to cook properly and evenly.
- Check your dried beans for stones before soaking—I’ve found pebbles in dried beans more times than I’d like to admit.
- Every bean batch cooks differently depending on age and storage, so trust your teeth over the timer. Older beans can take up to 2.5 hours.
- The soup thickens considerably as it sits since beans continue to absorb liquid—this is normal and actually quite nice.
Storage Tips:
- Refrigerator: Store in an airtight container for up to 5 days. The flavors develop beautifully overnight and the soup becomes even more satisfying.
- Freezer: Freezes perfectly for up to 3 months. Cool completely, then portion into freezer-safe containers leaving space for expansion.
- Reheating: Stovetop is best—add a splash of broth to thin if needed and heat gently over medium-low. Microwaving works fine and won’t hurt the beans.
- Beans continue to absorb liquid over time, so the soup gets thicker the longer it sits—just thin with extra broth when reheating.
