1. The night before, rinse those dried lima beans under cold water, picking out any stones or weird-looking beans. Cover them with plenty of water in a large bowl—they’ll expand significantly overnight, so use a big bowl.
2. The next day, drain and rinse your soaked beans really well. Heat that olive oil in your largest pot over medium heat and toss in the diced onion, carrots, celery, and minced garlic. Let everything cook down until soft and fragrant, about 5-7 minutes, stirring occasionally.
3. Add those drained lima beans to the pot along with your vegetable broth, dried thyme, dried rosemary, and a good pinch of salt and pepper. Crank the heat up to bring everything to a boil.
4. Once it’s boiling, drop the heat back down to low, cover the pot, and let it simmer gently for 1 to 1.5 hours until those beans are completely tender and creamy. Check them at the 1-hour mark by tasting a few—they should practically melt in your mouth with no chalky texture.
5. Grab your immersion blender and partially blend the soup, pulsing a few times to break down maybe a third of the beans while leaving the rest whole. This creates that amazing creamy texture without any dairy. If you don’t have an immersion blender, scoop out about 2 cups of soup and blend it smooth in a regular blender, then stir it back in.
6. Taste and adjust your seasoning generously—lima beans absorb salt like crazy, so be bold. Serve hot in deep bowls, garnished with fresh parsley and maybe a drizzle of good olive oil if you’re feeling fancy.

Notes:

• Don’t skip the overnight soak—it’s not optional for good results

• Freezes beautifully for up to 3 months in freezer-safe containers

What Makes This Recipe Special:

This soup showcases bush lima beans—smaller and creamier than large Fordhooks—at their absolute best, using their natural tendency to break down slightly for creating restaurant-quality silky texture without any cream or flour. The technique of partially blending maintains visual interest while honoring the 4,000-year tradition of using these nutritional powerhouses that sustained entire civilizations with their protein, fiber, and mineral content.
