THIS is one of those soups that makes you feel good about your health and is still incredibly delicious and satisfying. Beans are probably the most underrated super food. They’re packed full of fiber, protein, and antioxidants, while still being super inexpensive and shelf stable. And when you get 15 different varieties all in one pot, you’ve got a serious nutrition powerhouse! I decided to make it a Vegetarian 15 Bean Soup (it’s actually vegan) this week, but you could always add some bacon, a smoked ham hock, or smoked turkey leg to your soup for a little extra smoky flavor.

What Kind of Beans Do I Use?

“15 Bean Soup” mixes are fairly common in most major grocery stores, and they are sold right along side the other dry beans. I used Hurst’s Brand, which are in many major grocery stores. They’re basically just a mix of 15 bean varieties in one bag, and they’re quite beautiful, with all their different colors, patterns, and sizes. They usually come with a seasoning packet, just like instant ramen, but I prefer to add my own herbs and spices.

What to Serve with Bean Soup

While this soup itself is vegan, I ended up topping it with some shaved parmesan. Other good toppings would be a dollop of sour cream, Greek yogurt (you could do coconut yogurt to keep it vegan), or even some shredded cheddar or Monterey Jack. And I definitely suggest serving with some crusty bread on the side (try this no-knead bread).

How to Store the Leftovers

This Vegetarian 15 Bean Soup will freeze great, so don’t be afraid of the recipe’s large volume! Just divide it up after cooking, cool, then transfer to the freezer for long term storage. This soup does take some time to prepare, but most of it is passive time. So plan this recipe for a weekend or your day off so you can keep an eye on it while double tasking with something fun, like watching a movie. :) And don’t forget to start soaking the beans the night before!

Instructions 

  • The night before, place the beans in a large bowl and add cool water until the beans are covered with twice as much water as the beans. Let the beans soak overnight, or for at least 8 hours, in the refrigerator.
  • When you’re ready to begin cooking, drain the beans in a colander and rinse them well with fresh water. Set the beans aside so they can begin to warm up.
  • Mince the garlic and dice the onion. Add the garlic, onion, and coconut oil to a large soup pot. Sauté over medium heat for about 3-5 minutes, or until the onions are soft and transparent.
  • While the onion and garlic are sautéing, dice the celery and carrot. Once the onions have softened, add the carrot and celery to the pot and sauté for about 5 minutes more, or just until the celery starts to soften.
  • Add the beans to the pot along with 6 cups of water, and stir to combine. Place a lid on the pot, turn the heat up to medium-high, and bring it up to a boil. Once it reaches a rolling boil, turn the heat down to low or medium-low, and let the beans simmer for 90 minutes, stirring occasionally.
  • After 90 minutes, the beans should be quite soft and have broken down a bit, causing the water to look slightly thick and cloudy. Add the diced tomatoes (with juices), cumin, oregano, smoked paprika, cayenne pepper, and parsley to the pot. Stir to combine, then let the soup simmer for another 20 minutes.
  • Taste the soup and add salt to taste (I added 1.5 tsp). Finally, stir in the apple cider vinegar. Keep in mind that as the soup is stored in the refrigerator, the salt may absorb into the beans and taste more muted. You may need to add more salt the next day.

Notes

*This is just a mix of 15 bean varieties in one bag, with an envelope of seasoning included. I used only the beans and tossed the seasoning packet.
**I used coconut oil because it has a mouthfeel similar to animal fat. You can use your favorite cooking oil in its place, if you prefer.

How to Make 15 Bean Soup – Step by Step Photos

Soaked 15 bean mix in a large bowl of water

The night before place 1 pound of the dry 15 bean mix (do not use the seasoning packet) in a large bowl. Cover it with enough water so there is double the amount of water as beans. Refrigerate the beans overnight, or for at least 8 hours. This is what they look like after soaking. When you’re ready to start cooking, drain the beans in a colander and rinse them well with fresh water.

Sauté Onions and Garlic

Dice one yellow onion and mince two cloves of garlic. Add the onions, garlic, and 2 Tbsp coconut oil (or your favorite cooking oil) to a large pot. Sauté over medium heat until the onions are soft and translucent. 

Sautéed Carrots and Celery

While the onions and garlic are cooking, peel and dice 4 carrots, and dice 3 ribs of celery. Add them to the pot and continue to sauté just until the celery begins to soften (about 5 minutes more).

Add Soaked Beans to Pot

Add the rinsed and drained beans…

Add Water to soup pot

And 6 cups of water. Place a lid on the pot, turn the heat up to medium-high, and let it come up to a boil. Once it reaches a boil, turn the heat down to low or medium low, and let it continue to simmer for 90 minutes. Stir it occasionally as it simmers.

Simmered Beans and vegetables

After it’s simmered for 90 minutes, the beans should be very soft and be breaking down. The broth will look all cloudy like this, and kind of pale in color. 

Add Tomatoes and Spices to soup

Now it’s time to add those top note flavors! Add one 15oz. can of diced tomatoes (with the juices), 1/2 Tbsp smoked paprika, 1 tsp oregano, 1 tsp cumin, 1/4 tsp cayenne pepper, some freshly cracked pepper, and a handful of chopped fresh parsley. Stir everything to combine, then let the soup simmer for another 20 minutes or so.

Season soup with Salt and ACV

And now it’s looking much more vibrant. BUT we haven’t added ANY salt yet, so the flavors are still quite muted. Now it’s time to season with salt to taste. I ended up using 1.5 tsp, but I suggest starting with 1/2 tsp, and increasing from there until the flavors really pop. Keep in mind that as you refrigerate this, the salt will absorb into the beans some and become more muted, so you may need to add more the next day. 

Finished pot of Vegetarian 15 Bean Soup

Finally, stir in a couple teaspoons of apple cider vinegar to brighten it all up, and it’s done!

  1. This is delicious! Your recipes are always spot-on – I made this exactly as instructed (1.5 tsp salt was perfect), and it is *so* hearty, filling, and flavorful! It has major visual appeal, too. I sometimes struggle with bean dishes looking kind of boring and monotonous, but there are so many different colors, flavors, and textures going on. And finally, it makes a LOT! That’s my work lunches sorted for the next week or so, with plenty leftover to freeze.

  2. Thanks for this recipe. I made this today for lunch and simply followed your recipe. It turned out perfect. While serving I sprinkled little bit of crushed red peppers to make it a bit spicy. Delicious. 

  3. Great recipe!! Just wanted to add — I used my electric pressure cooker/instant pot at low pressure for 40 minutes and all the beans were cooked perfectly. (I still soaked the beans for about 6 hours) 
    You could probably get away with not soaking and cooking for 40 minutes on high pressure. I think beans come out better after soaking though. 

  4. looks great! I think though there is an error in the nutritional info as there is more fibre (49gms? ) per serving than total carbohydrates which is impossible.

    1. Lol, you’re right! That is impossible. :P Let me run it through the calculator again.

  5. Just finished making these beans and gave a taste and wow! So delicious! The only things I did not use were cayenne & parsley since I did not have. I also added some fresh dill, just a tiny amount and fresh thyme.

  6. I must have done something wrong – after 70 minutes of simmering, I checked and the soup was extremely thick. I mixed in all ingredients at that point and didn’t do any more cooking. It was so thick we were able to eat it with a fork. Besides that, it was really good and I will probably try to make again! It may have been user error, but I thought I followed the recipe to a T.

    1. Did you maybe use a bag of beans that was 20oz instead of 16? I did that the first time and had the same problem. Now I just add two extra cups of water (except I use broth) if I’m using the 20oz bag I usually find at the store.

  7. this recipe is a true WINNER.
    it makes a bunch and freezes well.
    i try to eat 3 servings a day and having this in the fridge or freezer makes it easy.

  8. I made this today and I am impressed. I have been struggling to make vegan recipes that aren’t Mexican food haha. It was so filling and so tasty. 

    I could really taste the fresh parsley from my garden and I was so surprised by how spicy it was. It went perfectly with bread and I can’t believe it’s not butter. Now I just need to make the bread to go with it haha. 

    Thank you for sharing this, I’m going to snoop through your other vegan friendly recipes. I really enjoy your budget break down as well. I will definitely share this one. 

  9. Made this one with a generic “mixed bean” bag, and cooked it in vegetable puree (I used a pre-prepared one from the store, but it is easy to make, too) and added potatoes. I like it and it will become a regular!

  10. I use a lot of dry beans so I slowly filled a jar with chickpeas, kidney, black, pinto, red/brown lentils, and green/yellow split peas. It ended up being 20 oz instead of the 1 lb Beth used, so I added a cup of water. I made sure to boil for at least 10 minutes before turning down to simmer due to the kidney beans. It needed a lot of salt (probably a full tbsp). This is even better the next day after sitting in the fridge. So cheap too!

  11. Excellent,  I used spinach instead of carrots, and home stewed, canned toms with a quick pulse in the blender. Dried parsley works fine. Really a nice meal!

  12. Really enjoyed the soup! A bit on the spicy side for our family’s taste, but served with cornbread to help with the spice and it was a lovely meal! Great for sharing too.

    1. I probably wouldn’t use a slow cooker for this one, since some beans need a more vigorous boiling than you can get in a slow cooker to break down a natural toxin they contain. Beans in the kidney bean family need to be boiled heavily for at least ten minutes, so it’s not advised that they be cooked in a slow cooker.

  13. I absolutely loved this soup!! Often simple recipes just don’t turn out well for me but this was a major exception. We ate it after almost 2 hours simmering but later I put the leftovers on to simmer some more because they were still slightly hard (even though I soaked for about 18 hours!). The main change I made was to add crushed tomatoes rather than diced. It was truly delicious. Served with broccolini and cornbread. Thank you!

    1. Great recipe. Made this tonight in my pressure cooker. I didn’t measure my seasonings cause I was too lazy, Omitted the pepper – I couldn’t find it in my cupboard 😔, added a bay leaf and veggie bouillon and it turned out great! Love the cornbread accompaniment I’ll make some tomorrow to go with the leftovers. Thank you for sharing.
