Best Instant Pot Pork Chops Cooking Time & Method: You wouldn’t want to overcook pork chops as they’ll become tough and dry. Since pork chops cook in a flash in the pressure cooker, we did a Pressure Cooker Pork Chops Experiment to find the best cooking time to make perfect instant pot pork chops! After testing with 5 batches of Instant Pot pork chops, we found cooking at High Pressure for 1 minute, then Natural Release creates a delicious and perfectly cooked pork chops.
Purchasing Pork Chops: Try to choose pork chops with some marbling of fat. The pork chops we used were roughly 1.25 inches thick.
Tenderize the Pork Chops: Make sure to tenderize the pork loin chops before marinating them. This is an important step!!
Mixing in the Tomato Paste: Mixing in 2 ounces tomato paste to 8.5 ounces of water should not cause scorching. If you are unsure, just let the tomato paste sit on top of all the other ingredients unmixed. Avoid mixing in the tomato paste if you exceed the 1 cup of tomato paste to 5 cups of water ratio.
Water vs. Chicken Stock: We used water instead of our homemade unsalted chicken stock in this recipe as most Cha Chaan Teng use water (way cheaper) to make this tomato sauce.
