Step 1

Put dry pinto beans into slow cooker.

Step 2

Fill crock-pot nearly to the top with water, about ¾ of the way full.

Step 3

Crush chicken bouillon cubes over the top of water, sprinkling evenly. Next, sprinkle garlic salt evenly over top. Drop the half medium sweet onion into slow cooker.

Step 4

Cook on low until beans are soft, about 8-10 hours. (stir occasionally during cooking process. You may have to add more water as beans absorb water, so check on them periodically.)

Step 5

Strain beans or pour off juice, saving the juice in a separate bowl.

Step 6

Add ½ cup of butter and a small amount of juice that beans cooked in.

Step 7

Use a hand blender to mash beans. Add juice and blend to obtain desired consistency. You want to leave beans a little runny as they will set up quite fast.
