Pour half of the teriyaki sauce to the Instant Pot insert and add the beef. Stir and add in the rest of the sauce.
2.5 cups teriyaki sauce
Lock the lid into place and set the steam release handle (valve on top) to “Sealing”. Press Manual>High Pressure>12 minutes.
When the Instant Pot has finished cooking, allow it to sit for 15 minutes (this is called a natural release). If the pressure indicator is still up, flip the vent to “venting” to remove any remaining pressure.
Serve beef and sauce over rice or veggies.
Notes
If you prefer a thicker sauce, combine 1 tbsp of cornstarch with 2 tsp cool water and stir thoroughly. Add to the Instant Pot when it has finished cooking. Press “sauté” and stir constantly for 3-4 minutes, or until the sauce has thickened. It will continue to thicken a bit as it cools.Stovetop instructions:
