charro beans and how do you store them?

I love charro beans so much and will always make it whenever I want it, but the problem is its a lot (I cooked 1 bag of pinto beans) and idk how to store it, when I put it in the refrigerator the soup/broth gonna be soaked and it changes the texture😥 if I put it on slow cooker with "keep warm" for days will it make them turned out mushy? how do you store your charro beans if you can't finish them in a day? thank you in advance.
