Serves 4
This soup is inspired by the Brazilian potato and kale soup called caldo verde (“green broth”). Some versions add sausage into the mix. This one has poached eggs.
Prep: 10 minutes
Cook: 30 minutes
Total: 40 minutes
Heat the olive oil over medium heat in a large pot. Add the leeks, salt, and pepper and cook, stirring occasionally, until the leeks are softened but not browned, about 4 minutes. Add the garlic and cook, stirring, for 1 minute. Stir in the broth and potatoes and bring to a boil. Reduce the heat, cover, and simmer until the potatoes are tender, about 10 minutes.
Add the greens and cook over medium-high heat, stirring occasionally, until the greens are wilted, about 2 minutes. Reduce the heat to low and stir in the parsley and lemon zest. Break an egg into a small bowl and slide it into the soup. Repeat with the remaining eggs. Cover and simmer until the eggs are cooked to desired doneness, 4 to 6 minutes.
Drizzle each serving with lemon juice and olive oil. Season with salt and pepper to taste.
TIP Look for washed and chopped greens near the packaged lettuce in the produce aisle of the supermarket.
