Combine chicken broth and rice in a medium pot over high heat. Bring to a boil, reduce heat to medium-low, cover partially and simmer 18–20 minutes until rice is tender.
Egg-Lemon Mixture
In a bowl, whisk eggs until frothy. Add lemon juice and whisk until fully blended.
Ladle ½ cup hot broth into the egg-lemon mixture, whisking constantly to temper.
Finishing
Slowly pour the tempered egg mixture back into the pot while stirring gently. Stir in shredded chicken and cook 2–3 minutes until heated through. Season with salt and freshly ground black pepper to taste.
Notes
Allow the rice to finish absorbing liquid off the heat for a slightly firmer texture.When reheating leftovers, stir in a splash of broth over low heat to restore the soup’s glossy silkiness.Always whisk room-temperature eggs and add hot broth slowly to prevent curdling.
