Season the pork chops heavily on both sides with salt, pepper and garlic powder.
Set the Instant Pot to Saute. Add the butter and olive oil.
Sear the chops 2 minutes per side, then remove them to a plate.
Add the minced garlic and cook 30 seconds, until fragrant.
Pour in the chicken broth and scrape the bottom of the pot completely clean. Every browned bit must lift or the pot will throw a BURN error.
Stir in the Dijon mustard.
Return the chops to the pot.
Seal and pressure cook on HIGH for 5 minutes.
Natural release for 5 minutes, then release the remaining pressure.
Remove the chops again and set them aside.
Switch back to Saute. Add the heavy cream, Parmesan, cream cheese and red pepper flakes.
Stir 2 to 4 minutes until the sauce thickens.
Return the chops to the sauce and turn to coat.
