Chicken & Kale Soup
1 tablespoon extra-virgin olive oil
1 ½ cups chopped yellow onion
1 tablespoon minced garlic
1 (15 ounce) can no-salt-added great northern beans, rinsed
12 ounces boneless, skinless chicken breast or chicken tenders
2 medium Yukon Gold potatoes, peeled and diced (1/2-inch)
6 cups unsalted chicken broth
3 thyme sprigs
1 teaspoon kosher salt
½ teaspoon ground pepper
3 cups chopped kale or 1 (10 ounce) package frozen chopped kale
2 tablespoons lemon juice
Heat oil in a large, heavy pot over medium heat. Add onion; cook, stirring occasionally, until softened, about 5 minutes. Add garlic; cook, stirring constantly, until fragrant, about 1 minute. Add beans, chicken, potatoes, broth, thyme, salt and pepper. Bring to a boil over medium-high heat; reduce heat to maintain a simmer. Simmer, covered, until the potatoes are tender and an instant-read thermometer inserted in the thickest portion of the chicken registers 165°F, about 18 minutes.
Transfer the chicken to a plate and, using 2 forks, shred it into bite-size pieces. Stir kale into the soup; cook over medium heat, stirring often, until the kale is wilted and tender, about 2 minutes. Remove from heat; stir in the shredded chicken and lemon juice. Remove the thyme sprigs before serving. Serve hot.
