Instructions. Start by making the pasta, add the macaroni and water (or vegetable broth) to the Instant Pot. Set the manual high pressure for 4 minutes.
Make sure that the vent is sealed. When the timer beeps and the four minutes are up, do a quick release.
If you let it naturally release, or it will overcook. Then mix in the cheese, butter, milk, hot sauce and mustard, stir until everything is melted. If you need more heat for the melting, just press the keep warm or saute' button. I didn't need more heat, everything melted for me.
