Sauté the Vegetables
Heat the olive oil in a large pot or Dutch oven over medium heat. Add the mushrooms, carrot strips, and the white parts of the scallions. Stir and cook until softened, about 5 minutes.
Add Aromatics
Stir in the minced garlic and grated ginger. Cook for about 1 minute until fragrant.
Prepare the Broth
Pour in the chicken or vegetable broth, soy sauce, rice vinegar, and sugar. Stir to combine and bring the soup to a gentle boil.
Add Bok Choy and Potstickers
Carefully add the baby bok choy and frozen potstickers to the boiling broth. Reduce the heat to medium-low and simmer for about 5 minutes, until the potstickers are cooked through and the bok choy is tender.
Finish with Sesame Oil
Remove the pot from the heat and stir in the toasted sesame oil for a rich, nutty flavor. Adjust seasoning with salt if needed.
Serve
Ladle the soup into bowls, garnish with the green parts of the scallions, and add optional toppings like chili crisp, toasted sesame seeds, furikake, or red pepper flakes. Serve hot and enjoy!
