Add half the oil to a large Dutch oven, or other heavy bottomed soup pot, set over medium/high heat. Add the sausage and saute, crumbling as it cooks, until completely browned and caramelized. Using a slotted spoon transfer the sausage to a waiting plate and set aside.
3 tbsp extra virgin olive oil, 1 lb ground Italian sausage
Add the rest of the oil, onion, carrot, celery, garlic, and Italian seasoning to the pot. Stir everything together to evenly combined and saute until the vegetables have softened.
1 large yellow onion, 3 medium carrots, 3 stalks celery, 4 cloves garlic, 1 tbsp Italian seasoning
Add the broth, beans, and cooked sausage to the pot, stirring again until evenly combined.
8-10 cups chicken broth, 2 15 oz cans cannellini beans
Bring the soup to a boil, then immediately reduce the soup to a simmer over low heat. Simmer, stirring occasionally, for 15 minutes.
Remove the pot from heat and stir in the kale. Cover the pot with the lid and let it rest for 5-7 minutes to allow the kale to wilt.
1 large bunch kale
Carefully taste the soup since it will be very hot, and adjust the seasonings if needed.
salt & pepper
Ladle into bowls, serve warm, and enjoy!
