Step 1

Place the beef chunks into the metal insert of an Instant Pot. Add the water, fish sauce, 2 tablespoons coconut aminos, 1 tablespoon Diamond Crystal kosher salt, shiitake mushrooms, sliced ginger, and garlic. Cut two of the scallions into three pieces and add it in.

Step 2

Thinly slice the remaining two scallions and reserve for garnish.

Lock the lid of the Instant Pot and program it to cook for 35 minutes under high pressure. When the beef soup is finished cooking, let the pressure come down naturally.

Step 4

While the beef soup is cooking, bring a pot of water to a boil. Add a large pinch of salt.

Step 5

When the water is boiling, add the baby bok choy and cook for 1 to 2 minutes or until tender crisp. Remove the bok choy with a slotted spoon and set aside.

Add the toasted sesame oil to the beef soup. Taste the soup and adjust seasoning if needed.
