This soup with pinto beans and chunks of potatoes, features a tomatoey beef broth and juicy smoked sausage, making it a cozy meal to warm up with.
Cover pinto beans with water in a large bowl and allow to soak, 8 hours to overnight. Drain.
Melt butter in a 6-quart stockpot over medium heat. Cook and stir onion and celery in hot butter until vegetables are tender, about 5 minutes. Stir garlic into onion mixture and cook until fragrant, about 1 minute more.
Stir beef broth, tomato juice, sugar, and drained pinto beans into vegetable mixture and bring to a boil; reduce heat to medium-low and simmer until beans are tender, about 1 hour and 15 minutes.
Mix potatoes, carrots, oregano, salt, and black pepper into bean soup; simmer until potatoes are tender, about 30 minutes more.
Preheat the oven's broiler and set the oven rack about 6 inches from the heat source.
Place smoked sausage on a baking sheet.
Bake sausage in the preheated oven until browned, about 10 minutes.
Cut sausage into quarters, then slice. Add sausage and parsley to soup; continue to simmer for 10 more minutes.
