This Vegetarian Egg Drop Soup is a quick, comforting Chinese-inspired soup that comes together in just 15 minutes. A rich, well-seasoned vegetable broth is thickened with a cornstarch slurry, then finished with silky ribbons of beaten egg, toasted sesame oil, and fresh green onions. It's completely meat-free, naturally low-carb, and endlessly customizable with add-ins like corn, tofu, or mushrooms.

3large eggsbeaten until fully combined
2tbspcornstarch

1/4tspturmericoptional, for golden color

For Garnish
2green onions (scallions)thinly sliced
Instructions
Beat 3 eggs in a liquid measuring cup until fully combined. In a separate small bowl, whisk together the cornstarch and cold water until completely smooth with no lumps.
Add the vegetable broth, soy sauce, ground ginger, white pepper, and turmeric (if using) to a medium saucepan over medium-high heat. Bring to a gentle boil.
Reduce heat to medium, give the cornstarch slurry a quick stir, and pour it slowly into the simmering broth while stirring constantly for about 30 seconds until the broth thickens and turns glossy.
Reduce heat to low, then slowly stream the beaten eggs into the broth in a thin, steady stream while stirring gently in a circular motion. Let the eggs rest undisturbed for 10-15 seconds to set.
Stir in the toasted sesame oil and taste the soup, adjusting salt or soy sauce as needed. The soup is ready when hot, fragrant, and seasoned to your liking.
Ladle the soup into bowls and top generously with sliced green onions. Serve immediately while piping hot.
Notes
Use a flavorful vegetable broth you'd be happy drinking on its own. The broth is the foundation of this soup, so quality matters.
Always mix cornstarch with cold water, never warm or hot. Warm water causes the starch to cook prematurely and creates lumps in the slurry.
Reduce the heat to low before streaming in the eggs. A boiling broth scrambles the eggs rather than forming silky ribbons.
Pour the eggs from about 6 inches above the pot in a very thin, slow stream for long, delicate ribbons. A fast pour creates smaller, fluffy egg pieces.
Don't skip the sesame oil. It goes in at the very end off the heat to preserve its full nutty flavor and aroma.
For a vegan version, substitute the eggs with Just Egg liquid. It streams and sets in broth in a very similar way to regular eggs.
Swap soy sauce for tamari or coconut aminos and verify your broth is certified gluten-free to make this soup completely gluten-free.
Optional add-ins: stir in 1/2 cup canned corn, cubed firm tofu, sliced shiitake mushrooms, or a handful of baby spinach after the broth thickens and before adding the eggs.
Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Do not freeze; egg ribbons break down when frozen and thawed.
To reheat, warm gently on the stovetop over medium-low heat and add a splash of broth to thin if needed. The soup thickens as it sits.
