Pour one cup of water into the pot. Place the trivet in the pot. Season the chicken with salt and set it on the trivet.
Close and lock the lid, set the vent to sealing. Pressure cook on high for 8 minutes for thin chicken or 10 minutes for thicker chicken. Allow a 5 minute natural pressure release, then let out the remaining pressure and transfer the chicken to a cutting board to cool. Note: You can skip this step if you're using pre-cooked chicken. Just warm the chicken up before putting it in the rice in step 4.
Rinse the rice well under cold water until the water is clear. Add the rinsed rice, chicken broth, and onion to the Instant Pot and secure the lid.
Press the pressure cook button and set the time to 3 minutes. When done, allow the pressure to release naturally for 10 minutes.
While the rice is cooking, cube the chicken.
Open the lid and fluff the rice. Add the soy sauce and toasted sesame oil, then add the peas and carrots and chicken. Stir well to combine. Place the lid on top and allow it to sit on Keep Warm for 5 minutes.
Turn on Saute mode to low heat (if your Instant Pot has this function). Push aside the rice to make a well. Add butter to the well and when it’s melted, pour the beaten eggs into the well. Cook, stirring constantly, until the egg is cooked. Then fold the egg into the rice mixture. Season with salt and pepper, to taste. Serve with sliced green onion and sesame seeds.
Notes
You can save time by using pre-cooked chicken, if you want.
