Black Bean Soup with Lime and Cumin
Not rated yet. Be the first.
Dried beans, toasted cumin, a little smoke from the chipotle, and a squeeze of lime at the end. Your uncle wanders in to ask if it's ready. It isn't, and he stays by the stove anyway.
The short version
Soften onions and peppers in oil, toast the spices with garlic and chipotle, then simmer a pound of dried black beans in water for 1½ to 2 hours. Blend a third of the soup back in, then finish with lime and cilantro. Soak the beans overnight to save 45 minutes.
What makes ours better
what we fixed so you don’t have to
-
Toast the spices in the oil. Cumin, chili powder and oregano cooked for a minute in hot oil turn deeper and rounder than spices stirred into liquid, and the flavor carries through the long simmer.
-
Blend a third of the soup. Puréed beans thicken the soup into something creamy without any cream or flour, and the whole beans left in the pot keep their shape.
-
Add one chipotle in adobo. A single chile adds smoke and a slow, gentle heat that makes people ask what is in there.
-
Finish with lime juice. Acid at the end makes the earthy beans taste brighter and is the difference between good black bean soup and a great one.

Steps
nobody opens the oven door. looking at you, Dad.
-
Soften the vegetables
Heat the oil in a large Dutch oven or soup pot over medium heat. Add the onions and bell pepper. Cook, stirring often, until soft and starting to turn golden at the edges, 8 to 10 minutes.
About 9 min. Cook mode has a timer for this step.
-
Toast the spices
Stir in the garlic, serrano, chili powder, cumin, oregano and chipotle. Cook, stirring, for 1 minute, until the spices smell fragrant and the garlic is soft but not browned.
Keep the heat at medium. Burned garlic turns the whole pot bitter.
About 1 min. Cook mode has a timer for this step.
-
Add the beans and liquid
Drain the beans if they were soaked, then add them to the pot with the water and salt. Bring to a boil, then lower the heat and simmer, partially covered, stirring now and then.
-
Simmer until completely soft
Cook until the beans are completely tender and creamy inside, 1¼ hours for soaked beans or about 2 hours for unsoaked. Add a cup of hot water if the beans are no longer covered. Test by mashing a bean against the side of the pot, and give it 15 more minutes if it resists.
Old dried beans can take longer. Keep simmering until they are soft rather than shortening the time.
About 90 min. Cook mode has a timer for this step.
-
Blend a third of the soup
Ladle about 3 cups of beans and broth into a blender, vent the lid and purée until smooth, or use an immersion blender and pulse the pot a few times. Stir it back into the soup and simmer for 5 more minutes, until the soup has thickened to a stew-like body.
Blend hot liquids with the lid cracked and a towel over the top, so steam doesn't blow it off.
About 5 min. Cook mode has a timer for this step.
-
Season and finish
Stir in the lime juice. Taste and add salt until the beans taste fully seasoned, usually another 1 to 2 teaspoons. Serve with cilantro, avocado, lime wedges and hot sauce.
Good to know
things I learned the hard way, so you can skip that part
- Soaking is optional but helps the beans cook evenly and shortens the simmer by about 45 minutes. Cover with cold water by 2 inches and soak 8 to 12 hours, then drain.
- Pressure cooker. Skip soaking, use 5 cups of water, and cook at high pressure for 30 minutes with a 15-minute natural release.
- For a smoky, meaty soup, simmer a smoked ham hock or a few strips of bacon with the beans and remove them before blending.
- Canned beans shortcut. Use four 15-ounce cans, drained, with 4 cups of broth, and simmer 25 minutes after step 3.
- Storage. Refrigerate up to 5 days. Freeze up to 3 months. The soup thickens as it sits, so thin it with water or broth when reheating.
Questions, answered
the questions my cousins text me
Do I have to soak black beans for soup?
No. Unsoaked beans take about 2 hours instead of 1¼, and they make just as good a soup. Soaking helps them cook more evenly.
Why are my black beans still hard after 2 hours?
Old beans, hard water or too much acid. Beans more than a year old can take much longer. Add the lime juice at the end, and keep simmering until they are soft.
Can I use canned black beans?
Yes. Use four 15-ounce cans, drained and rinsed, with 4 cups of broth. Simmer 25 minutes, blend a third, and finish as written. It will be a little less rich than the dried-bean version.
How do I thicken black bean soup?
Blend or mash some of the beans, as in step 5, and simmer uncovered for a few minutes. It thickens as it cools too.
Can I make black bean soup in a slow cooker?
Yes. Soften the onions and spices on the stove, then cook with the beans and 8 cups of water on low for 8 to 10 hours. Blend a third, then add the lime juice.
