Ooh, that looks nummy! I wouldn't mind making that in my slow cooker. Could you send the recipe my way?
There isn't a recipe, exactly. But the ingredients: a ham bone with some meat left on it (plus extra ham if you want a meaty soup), 8oz of dried white beans, carrots, celery, onions, salt, black pepper. Sadly I forgot the garlic, but it's okay without it. I may add some in when I reheat a bowl.
I don't have exact amounts on the veggies, but I think it was a little more than 4 cups of diced carrots, celery, and onions.
My procedure: soak the beans overnight in enough water to cover plus an extra inch or so, with a 1/4 tsp of baking soda (acid can prevent beans from softening, some base/alkali can help counteract that.). Put the beans and the ham bone in 5 cups of water and 1 tsp salt and boil until the beans start to become tender. Cook the vegetables in a pan until mostly done to get a little browning and flavor, seasoning with salt and/or pepper (or add them to the beans earlier in cooking if that's easier). Take out the ham bone and add the veggies to the beans. Continue cooking the beans and veggies as you get the last of the meat off the ham bone and chop it up. Add the ham to the soup, check to make sure the beans and veggies are soft, and you're done. Optionally add some sauerkraut brine to the soup when serving for an extra kick of flavor (and probiotics!).
I don't now what the cook times would be in a slow cooker. I was cooking mine in an enameled cast iron dutch oven in a 350F oven. Took about an hour to soften the beans, and another fifteen minutes after I added the veggies.

this recipe from YouTube, though they use less veggies, and make a much larger batch.
