Turn the instant pot onto the Sauté mode. Let it heat up. Once the oil is heated up, sear the pork chops on both sides for about 2 minutes each or until browned.
Remove and set aside on a plate. Add the sliced mushrooms, onions, and fresh garlic to the instant pot and sauté them for about 1-2 minutes. Then turn the instant pot OFF.
Pour the beef bone broth into the pot and with a wooden spoon scrape any browned bits from the bottom of the pot and now add the pork chops back into the pot.
