Silky egg drop soup with wispy ribbons of egg in a savory broth is a light, healthy, high protein starter. This quick, family-friendly recipe comes together in just minutes.
In a medium saucepan over medium-high heat, bring the chicken stock to a gentle boil; carefully skim off any foam that rises to the surface for clarity.
In a small bowl, whisk the cornstarch with 2 tbsp cold water until fully dissolved, then slowly stir the slurry into the simmering stock to slightly thicken.
Lower the heat to medium-low and add soy sauce, sesame oil, white pepper, and salt, stirring gently to combine all seasonings evenly.
In a separate bowl, beat the eggs thoroughly. With the broth at a gentle simmer (not boiling), slowly drizzle the eggs into the broth in a thin stream, using a fork or chopsticks to stir in one direction and create wispy ribbons.
Allow the soup to cook for 30–60 seconds without stirring to set the egg ribbons, then add thinly sliced green onions right before serving. Serve immediately for best texture.
