Turn the Instant Pot to the Saute function and place ½ a tablespoon of butter in the pot until it melts. Sear the pork chops for 2 minutes on each side.
Remove the pork chops and add the remainder of the butter to the pot.
Saute the onion and mushrooms until the onions are softened. Add the garlic and stir until the garlic is fragrant.
Pour in the broth, soy sauce, and thyme. Scrape any bits off the bottom of the pot. This is called deglazing to prevent the burn notice coming up while pressure cooking.
Add the pork chops back into the broth.
Top the Instant Pot with the lid and seal the vent. Turn the pressure cooker on high. Set the timer for 5 minutes. Once it is done cooking, allow the natural steam to release for 8 minutes.
When the pork chops are done, remove them from the broth. Use a slotted spoon to remove mushrooms and place them in a bowl to use as a side.
Turn the saute function back on. Combine cornstarch and water and whisk to make a slurry. Use a whisk and continue to stir the gravy as it thickens.
Notes
Thick-cut pork chops between 1- 1 ½ inches thick work best. Any thinner will overcook.
Use low-sodium soy sauce and beef broth to keep the broth from getting too salty.
Letting the garlic cook until fragrant adds the best flavor that really enhances both the pork chops and the gravy.
Deglazing the bottom of the pressure cooker with broth and a wooden spoon is a win-win. The brown bits add amazing taste and keep the Instant Pot from giving a burn notice.
Stir the cornstarch slurry continuously to avoid lumps in the gravy.
Store leftovers in an airtight container in the fridge for up to 3 days. I like to store the pork chops and gravy separately.
Reheat leftovers on the stove with a covered pan and a splash of broth or water.
