Allow the pork chops to rest at room temperature for 30 minutes to take the chill off before beginning, if possible
Pat the pork chops dry with paper towels. In a small bowl, combine the seasoned salt, granulated garlic (or garlic powder), dried thyme, paprika, and pepper. Season both sides of the chops, patting the seasoning into the surface of the meat with your hands.
Add the oil in a large skillet over MEDIUM-HIGH heat. When hot, add the pork chops and cook, undisturbed, for 3 to 4 minutes per side, or until nicely seared. Turn off the heat under the skillet and transfer the chops to a plate and set them aside.
Add the sherry to the hot empty skillet then return the skillet to MEDIUM heat. Deglaze the pan by stirring to scrape up any browned bits from the bottom. Add the mushrooms and cook, stirring for about 2 minutes, just until slightly softened. Add the Worcestershire sauce and cook, stirring, for another minute. Add the cream of mushroom soup and gradually add the half-and-half (or whole milk), stirring in between additions, until the gravy is smooth.
Return the browned chops and any accumulated juices to the skillet and increase the heat to bring the gravy to a low boil. Immediately reduce the heat to LOW, spoon the gravy over the chops, and simmer, uncovered, for 5 minutes or until the pork chops are cooked through to an internal temperature of a minimum of 145 degrees F. Remove from the heat.
Season with additional pepper, garnish with parsley, and let rest for 5 minutes. Delicious served with mashed potatoes and plenty of mushroom gravy.
