Step 1

Put soy sauce, 2/3 cup water, brown sugar, garlic and ginger in a food processor or blender and process until smooth (if you'd like to make it without a food processor, mince garlic and ginger by hand and combine with soy sauce, water and sugar in a cup).

Step 2

Put sliced beef in the Instant Pot and pour soy sauce mixture over it. Toss with your hands to make sure all the beef is coated with soy sauce mixture.

Step 3

Close the lid of the Instant Pot and set the valve to a Sealing position. Press the "Pressure Cook" or "Manual" button and set the time to 10 minutes on High pressure.

Step 4

While the beef is cooking, put the broccoli in a microwave-safe bowl and microwave on High for 4 minutes if fresh (or 5 minutes if frozen).

Step 5

When the beef is done cooking, quick release (QR) the steam and open the Instant Pot lid.

Step 6

On the Instant Pot, press the Saute button and set the time to 15 minutes.

Step 7

In a cup, mix the cornstarch with 1/4 cup of hot water. Add the cornstarch mixture to the Instant Pot and mix until incorporated. The beef mixture will come to a boil and the sauce will gradually thicken (in about 3 minutes).

Step 8

Stir the cooked broccoli into the beef mixture and serve.

Step 9

Sprinkle with sesame seeds for garnish (if using).
