This Kale and White Beans Soup is so hearty and delicious. The savory smoked sausage gives the soup tons of flavor, too.
Cover beans with water by 2 inches in a pot and bring to a boil. Remove from heat and let stand, uncovered, 1 hour. Drain beans in a colander and rinse.
Cook onions in oil in an 8-quart pot over moderately low heat, stirring occasionally, until softened, 4 to 5 minutes. Add garlic and cook, stirring, 1 minute.
Add beans, broth, 1 quart water, cheese rind, salt, pepper, bay leaf, and rosemary and simmer, uncovered, until beans are just tender, about 1 hour.
