Whoever discovered beans gets a big fat medal of appreciation from yours truly. They’re just incredible. Incredible and cheap. And so is this Slow Cooker White Bean Soup. This soup is thick, warm, comforting, and flavorful… and cost me LESS THAN FIVE DOLLARS FOR THE WHOLE POT. That, my friend, is the magic of beans.

What Kind of White Beans Should I Use?
I suggest using navy beans first, because they are creamy and break down easily when cooked, which will give you this nice thick texture in the finished soup. If navy beans are not available, my second choice would be great northern beans. DO NOT use cannellini beans, which are part of the kidney bean family, and require a heavy boil to break down a natural substance called Phytohaemagglutinin, which is a gastrointestinal toxin. The slow cooker does not get the soup hot enough for long enough to break down the toxins in those beans.
Do I Need to Soak the Beans?
Nope! This recipe does not require pre-soaking the beans. Some people claim that soaking beans then discarding the soaking water can reduce flatulence, but I, personally, find no difference. If you prefer to pre-soak your beans, you will need to add less water to this recipe and will probably need less cooking time. I have not tested that method, so I do not have a specific amount of water or cooking time to suggest.
Can I Use Broth in Place of Water?
This awesome Slow Cooker White Bean Soup uses a medley of spices, herbs, and vegetables to make its own flavorful broth right in the slow cooker – no Better Than Bouillon soup base this time around, folks. Of course you always have the option to use broth in place of water if you wish, just be aware that you probably won’t need to add salt at the end of the recipe, as directed below.
Can I Add Meat?
Sure, if you prefer meat in your soup I would suggest adding a ham hock or a smoked turkey leg to the slow cooker with your soup as it cooks. They will provide a wonderfully smoky flavor and will reduce the amount of salt you’ll need to add at the end.
Is This Soup Freezer Friendly?
Yes! This Slow Cooker White Bean Soup freezer beautifully. Make sure to divide it into single portions and chill it in the refrigerator first, then transfer to the freezer once cold. I like to freeze my soups in reusable Ziploc containers, but freezer bags also work great. To reheat either use the defrost function on the microwave, or transfer to a soup pot and reheat over low, stirring often, until heated through.

How to Make Crockpot White Bean Soup – Step by Step Photos
Dice one yellow onion, four ribs of celery, and peel and slice 1/2 lb. carrots (about 4 carrots). Mince 4 cloves of garlic. Add the onion, celery, carrot, garlic and 2 Tbsp olive oil to a slow cooker (5 qt. or larger).
You’ll need one pound of dry navy beans or great northern beans. Again, DO NOT use cannellini beans, which are part of the kidney bean family, and require a heavy boil to break down a natural substance called Phytohaemagglutinin, which is a gastrointestinal toxin. The slow cooker does not get the soup hot enough for long enough to break down the toxins in those beans.
Briefly rinse the beans in a colander, then add them to the slow cooker along with 1 bay leaf, 1 tsp dried rosemary, 1/2 tsp dried thyme, 1/2 tsp smoked paprika, some freshly cracked pepper, and six cups of water.
Briefly stir the contents of the slow cooker to make sure all the flavors are distributed, then place a lid on top and cook on high for 4-5 hours or low for 8-9 hours.
After cooking on high for 4-5 hours or low for 8-9 hours it will look a little something like this. All the vegetables will have floated up to the top and the beans will have absorbed most of the water. Test a bean to make sure they are very soft. If they’re not yet soft, cook for one hour more (they should definitely be soft by this point, unless your beans are very old. Old beans sometimes do not soften no matter how long they are cooked).
Stir the soup and smash the beans against the side of the pot, which will thicken the soup (or you can use an immersion blender). The soup at this point does not contain ANY salt, so now it’s time to add salt so you can really taste all the different flavors. Begin adding salt, starting with 1/2 tsp and adding more until the soup is flavorful. I added 2 tsp total.
Serve hot with some crusty bread for dipping!
I’m making this today except I’m adding a little beer, and by “a little” I mean an entire bottle. I make baked white beans with beer and they’re delicious, so I thought it would add a little something extra. This makes the recipe slightly less thrifty, though.
NICE. :)
The idea that salting the beans makes them tough is a myth; the salt actually softens the skins, preventing blowouts, and seasons the beans all the way to the center. Adding ACID early in cooking (tomatoes or the like) will toughen the skins.
This recipe looks great! One question: would great northern beans be an okay substitution for the navy beans? Thanks!
Yep, that would work just fine :)
Just tasted this and what can I say…delicious! Budget friendly and goes a long way. We’ve had several unexpected guests at our house today and this has been in the slow cooker. I just love everyone’s faces as they walk in and smell it! Beth, thanks for saving my cooking “life!” My husband is extra grateful, too:) Keep up the amazing recipes.
Hooray! This looks delicious and perfect to cook on a work day! Getting the ingredients this weekend.
PS: I think it would be a great candidate for some yummy shredded cheese on top. Maybe mozzarella or cheddar.
The boyfriend and I loved it (and that’s saying something, cause he’s ridiculously picky). I subbed chicken stock (go go Better than Bouillon) and added some chicken sausage right at the end cause he wanted some extra meatiness, and I added in just a touch of chipotle pepper for smokiness, since I only had hungarian paprika. One minor freak out – I realized after buying my (like $4 worth of) ingredients that I only had a 3.5 quart slow cooker, but halving the recipe totally worked for two people, and made it even cheaper! I love you, I love your site, and I love this soup. Thanks so much for sharing!
I’ve never made bean soup! Only stews.
I’ll try with this one, looks delicious, and I love soup!! I often put some red lentils in to make a Good stock, or a few cooked beans, but have never tried it bean-based. And we have no slow-cooker. They are hard to find here in switzerland.
About how many servings does this make?
It makes about 9 cups, so I estimated about 6 servings (or 8 smaller servings).
Have this in the slow cooker now. I only had mixed soup beans so I used those. Also substituted homemade chicken stock for the water and added two Turkey legs from last Thanksgiving. can’t wait to try it!
It was a bit bland. We added
more garlic, cayenne, celery seed, and some prosciutto that I had handy. I think you need to start over with a ham hock – which I wouldn’t know about, except for you.
Huge success! I followed the recipe to a tee and it was the perfect consistency, with tons of flavor (which I usually find lacking in bean soups…). Just for fun I may experiment at some point swapping out the oil and salt with a ham bone the next time I have one (I think it would be really good with that slightly smoky flavor you get from the smoked paprika), but really it is phenomenal as is.
I would love a good beer cheese soup recipe!
Good idea!
Fantastic recipe!! This one is a keeper! The soup turned out heavenly. Change nothing! Your home will smell incredible too-bonus :) thanks Beth!
This looks divine! I will make it on the first cold and rainy day this autumn. Thank you for the recipe : )
Kielbasa! Sliced and added to the soup. Would make a WONDERFUL non-vegan bean soup.
