This ultrasimple bean soup has been on the menu at the U.S. Senate Dining Room and served to senators and their staff for more than 100 years. Even as politics have changed, this soup has remained basically the same: navy beans simmered to creamy tenderness with ham hocks, butter and onion. Fittingly, there is no consensus on where exactly the soup came from: Some say it dates back to the early 20th century, when Senator Fred Dubois of Idaho passed a resolution making it a menu staple. This slow-cooker version has updated the classic slightly, with the addition of carrots and smoked paprika. If you’d like more vegetables (how modern!), stir in about 8 ounces of chopped kale before serving. As a nod to Idaho, this version contains a single russet potato, which gets mashed at the end of cooking and thickens the soup beautifully.

Preparation

  1. Step 1

    In a 6- to 8-quart slow cooker, combine beans, garlic, carrots, ham hocks, onion, potato, butter, salt, smoked paprika and thyme. Top with 8 cups of water and several generous grinds of black pepper. Cook until the beans are very tender and creamy, about 6 hours on high. (Beans need to reach a simmer to be fully cooked and safe to eat, so be sure your soup reaches a vigorous bubble. This shouldn’t be a problem on the slow cooker’s high setting. Additionally, beans vary in cook time by age, so if your beans are older, you may need to cook a bit longer than 6 hours.)

  2. Step 2

    Pull out the ham hocks and put them on a cutting board to cool a bit. Using a fork, mash the potato pieces against the side of the slow cooker. Stir well to break down some of the beans, too. Stir in the vinegar. Pull the meat off the bones, add it back into the soup and discard the bones. Taste and add more salt or pepper as needed.

@David Looks like most of the sodium is coming from the 1 Tbsp of salt divided by 4 servings, which 4 servings may be a very generous bowl of soup. With the ham hocks alone, you should get enough salt to be flavorful. I’d make it without the added salt, and let people add salt to their servings.

I make this often with no meat, it highlights the great taste of the beans. Meat tends to overshadow the beans imho. I do use celery as well. And I saute the onions first. until browning, to add a little more depth of flavor. I alsolike to add some chopped carrots and celery in the last half hour or so to give it some color and a little of the texture you would get from the ham or turkey. Check out thermal cooking for another way to cook beans or soups in summer without adding heat to kitchen

This soup is so good, it'll knock your hocks off

Made as directed. Yielded 6 servings of 350 grams each, enough to fill cereal bowls to nearly full. Even on the third and final night of this we still found small pieces of bone so beware of bones if using ham hocks. Smoked ham shanks might be a safer choice.

I just made this exactly as written, except a smoked turkey leg instead of ham hocks. Delicious!

Not sure what I may have done wrong. Followed the recipe to the T. Came out very watery and bland.
