That’s a good looking variant on the classic bean recipes I’ve seen over the years, no doubt. Sounds delish! Is yours more creamy or soupy?
FWIW, I was taught from the very first pot of creole red beans I ever cooked that you just mash a bunch of them against the side of the pot.
I usually go for creamy-ish, both by cooking the beans until they're extremely tender and by mashing for a while. The fact I garnish with shredded cheese and Mexican-style crema makes it more creamy-ish, without question. Between the vaquero beans (which aren't entirely black) and using chicken soup base instead of pork, the soup was more brick-red than charcoal-black colored; still tasted good, though.
EDIT: I suppose it could be made more soupy by mashing less--I don't think you'd want to try to undershoot the cooking time (though to the extent I overcook the beans, you could shorten by that much).
