Step 1

Add the sauce ingredients to the Instant Pot. Soy sauce, vinegar, ginger, garlic, sugar, and white or black ground pepper.

Step 2

Then add the chicken, onion, zucchini (if you decide to pressure cook it, important to see notes below), and mushrooms.

Step 3

Secure the lid and set the vent to SEALING. Select the PRESSURE COOK/MANUAL setting and set the cooking time for 3 minutes at high pressure. The Instant Pot will take around 7-10 minutes to come to pressure and start cooking. When the cooking program ends, quickly release the steam.

Step 4

Press on SAUTE, and once the sauce comes to a gentle simmer, add the cornstarch mixed with water. Whisk until the sauce is thickened (it thickens very quickly).

Step 5

Serve over rice, and garnish with sesame seeds and chopped green onion.
