A thick, tangy broth loaded with tofu, mushrooms, and egg ribbons delivers bold sour and spicy flavors. This protein-rich, low calorie family soup is a Chinese restaurant classic perfect for calorie deficit eating.
Slice the tofu into 1/2-inch strips and set aside. Slice mushrooms and bamboo shoots thinly for rapid, even cooking.
In a large pot over medium-high heat, bring the chicken broth to a gentle simmer. Add mushrooms and bamboo shoots, then cook for 3-4 minutes until slightly tender.
Whisk together the cornstarch with 4 tbsp cold water to create a smooth slurry and add it to the simmering soup. Stir constantly until the broth thickens and looks glossy.
Reduce heat to medium-low. Pour in the rice vinegar, soy sauce, white pepper, and chili oil. Stir well to combine.
Add tofu and let it warm through for 2-3 minutes without breaking. Slowly drizzle the beaten eggs through a fork or chopsticks into the swirling soup, creating delicate ribbons. Stir gently for 30 seconds, then remove from heat immediately.
Sprinkle sliced scallions on top and serve hot to preserve the soup’s fresh tang and smooth texture.
