In the Instant Pot®, stir together the broth, vinegar, thyme, nutmeg, red pepper flakes, and salt. Mix in the frozen pepper strips.
Stand the pork chops on their sides in the pot, leaning them against each other and the sides of the insert, with room between each for liquid and pepper strips (avoid stacking them). Lock the lid onto the pot.
Option 1: Max Pressure Cooker Press Pressure Cook on Max Pressure for 16 minutes with the Keep Warm setting off.
Option 2: All Pressure Cookers Press Meat/Stew, Pressure Cook, or Manual on High Pressure for 20 minutes with the Keep Warm setting off. Ensure the vent is closed.
Use the quick-release method to bring the pot’s pressure back to normal. Unlatch the lid and open the cooker. Transfer the pork chops to serving plates and spoon some of the sauce and peppers over each. Enjoy!
