This brothy soup is based on stracciatella, Italy’s answer to egg drop soup. Here, we add ribbons of sautéed kale to the vegetable or chicken broth. Then eggs beaten with grated Parmesan cheese are stirred in to create the straccia, which in Italian means “rags” or “shreds.” While the soup cooks, bake some crusty garlic bread for dunking.
- 1Wash and dry the kale. Cut out the tough stems from the leaves and discard. Arrange the leaves in stacks, slice crosswise into 1/4-inch ribbons, and set aside. (You should have about 4 cups.)
- 2Heat the oil in a large saucepan over medium-high heat until shimmering. Add the kale and season with salt and pepper. Cook, stirring occasionally, until just wilted, about 3 minutes.
- 3Increase the heat to high, add the broth and measured salt and pepper, and bring to a simmer. Reduce the heat to medium low and continue simmering until the kale has softened but isn’t mushy and the flavors have melded, about 10 minutes. Meanwhile, place the eggs and cheese in a medium bowl, season with salt and pepper, and whisk until combined; set aside.
- 4Increase the heat to medium, slowly pour the egg mixture into the saucepan, and stir to combine. Return to a simmer, stirring occasionally to break up any large pieces of egg. Remove from the heat, taste, and season with salt and pepper as needed. Serve immediately.
