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. Yum!! I just made this on my work-from-home day and it was perfect! My grocery store had a 13 bean mix, which worked just as well. I did sub out water for vegetable broth so it did end up pretty rich but I might do half water next time just to make it a bit lighter. But otherwise I’m very excited to eat this all week!

  2. I made a few small modifications for my personal preferences (and added a bunch of chopped kale!) and this soup was delicious! The funniest thing was that one of my dogs was obsessed with this soup! Every time I would heat some up, he would beg for it!

  3. This was surprisingly good! I did use broth instead of water, upped the spices a bit, and used dried parsley instead of fresh because my grocery store was out. I think I actually preferred the dried though. I was hesitant about including the cumin because it has a very strong and specific flavor to me that I associate with certain foods and I wasn’t sure if it would be a good fit here. However, the combination of spices was absolutely perfect.

  4. This does look delish. But, holy moley, beans, y’all, beans. I love beans in all their many forms, but let’s just say that my daughter does not appreciate me eating them.

  5. I know you love the Instant Pot…..how can we do this in the Instant Pot?? I love beans from the Instant Pot

    1. Unfortunately, I’d need to test it in the IP before offering specific instructions. I do like my IP, but I don’t use it enough to be able to guess at this point. :)

    2. I just made this in my Instant Pot tonight! I sauteed the veggies and then added the beans, water, and spices and cooked it for 45 minutes on high pressure. I added the tomatoes when it was done and brought it back up to a simmer. If I had had more time I would have simmered for longer so the flavors could have blended a bit more. I didn’t use the parsley, but if I had I would have added it with the tomatoes. Worked perfectly! I skipped the soaking as well.

  6. Beth, in Step 5, when we simmer for 90 minutes, should the lid be on the pot, off the pot, or cracked just a little? Thanks!

  7. I haven’t tried this yet but want to. However I don’t want to soak the beans. So I’d like to know how many cups of beans you get out of the mixture so I can just open cans.

    1. It’s probably somewhere in the neighborhood of 6 15oz. cans. Just keep in mind that it won’t turn out quite the same with canned beans, and you won’t need all 6 cups of water, since the canned beans are already cooked.

  8. I made this on a snowy day at home and served it with fresh corn bread on the side. The whole family enjoyed it. Delicious!

  9. Did this in the instant pot. Sautee veggies, beans and water in (8 cups since no pre-soak). Added one spoonful of better than boullion veg. 45 min on high pressure, 40 min slow release, then quick released the rest. Came out excellent.

  10. I have been making your recipes for years, and every one is a hit. ย But this is the first I felt absolutely compelled to comment about. ย I literally said โ€œmmmโ€ out loud with every spoonful. ย Utter perfection! ย Bravo, and thank you so much! ย I canโ€™t wait to eat this again tomorrow for lunch :)

  11. Wonder what Rotel tomatoes would do to that loveliness… (rubbing chin)

      1. anytime a recipe calls for diced tomamos I use rotel . . . i love it!

  12. Do you think this would be fine in a pressure cooker? It might avoid some of the problems of the slow cooker with the cannelini beans.

    1. I made it in the pressure cooker and it is awesome! Sautรฉed the veggies in the pot, added beans and water and cooked 20 minutes. Added the tomatoes and spices and pressure cooked for two more minutes. Came out perfectly!

      1. When you used our pressure cooker, did you still soak the beans?

  13. I’ve got this on the cooker right now. They don’t sell 15 bean mixes here so I made my own and it’s more like eight kinds of bean. I also replaced half the water with vegetable broth because I had some I needed to use up, but otherwise I followed the recipe as written. Can’t wait to try it!
