How to Cook Dry Beans in a Slow Cooker

Use this recipe to learn how to cook dry or dried beans in your slow cooker or Crockpot
We eat a lot of black beans in our house.

For a while, I was making this black bean soup about twice a month, and I had to buy two cans of black beans and two cans of beef broth, and it was getting really expensive (Okay, okay, not really expensive. It certainly wasn't like eating steak for dinner every night, but for my tiny grocery budget, it felt expensive).

Also, my husband insists that the soup is perfect when eaten with tortilla chips, so suddenly I was buying 5 things specifically to put in this one soup.

I decided there had to be a cheaper way to get the black beans.

Thankfully, there is!

Making your own black beans in a slow cooker is incredibly simple, and extremely cheap.

They take a few hours to cook, but if you own a crockpot, they are the simplest things to make, and the flavor is amazing! They are way better and fresher tasting than your standard canned black beans.

Plus, this recipe yields about 6 cups, which is enough to make a few recipes.

If you have more than you can use in a week, you can freeze the cooked beans in the freezer for up to two months.

What are you waiting for?

Make these super delicious, very easy black beans!  Then you can make this fabulous black bean soup every month like me! Trust me, it's amazing.

  1. Just fyi and safety of health - always soak your beans the recommended time before cooking them. Lots of phytic acid in beans and black beans need to be soaked. Soaking in the crock pot whilst cooking them isn't what I mean, just in case you were going to point that out. Lol - they need an acidic medium and after they are soaked, THEN cook them in your crock pot - possibly for less time but that I'm not sure of. There are soaking charts out there on the net that show which soaking times for which nuts, beans, etc. God bless and thanks for the recipe! Here's a good site explaining why to soak. Happy Health!
