The crust on these pork chops is deep brown. The sauce itself is glossy and loose, tart from the apple and cider vinegar, with a savory depth from the white miso that rounds out the sweetness. It pools around the base of the chop and coats whatever you serve alongside. One pan, thirty minutes, and a sauce that tastes amazing.
Using paper towels, pat the chops completely dry. Season all sides with salt and pepper. Let stand at room temperature for 20 minutes.
In a large stainless-steel or cast-iron skillet over medium-high heat, add the oil and heat until shimmering. Place the pork chops in the pan without crowding them. Sear undisturbed for 3 to 4 minutes until deep golden brown. Turn and add butter, garlic, and thyme. Tilt the pan and baste the chops with the butter repeatedly for 2 to 3 minutes, until the internal temperature registers 135°F when tested with a meat thermometer.
Transfer the chops to a plate or cutting board. Tent loosely with foil and rest for 5 to 8 minutes. The internal temperature will increase to 145°F while resting.
Pour off all but about 1 tablespoon of fat from the skillet, while keeping the fond in the skillet. Return to medium heat. Add the apple slices and shallots. Cook, stirring occasionally, for 3 to 4 minutes until softened and lightly caramelized. Add the cider and scrape up any browned bits from the bottom of the pan. Cook 1 minute until mostly reduced.
Add the stock. Whisk the miso paste into the pan liquid until fully dissolved. Do not boil. Simmer 2 to 3 minutes until the sauce coats the back of a spoon. Stir in the cider vinegar. Remove from the heat and add in the cold butter, one cube at a time, until the sauce is glossy.
Spoon the miso apple pan sauce over the chops. Serve immediately.
Notes
White miso is the best choice. Yellow miso works as a substitute. Red miso is too intense and will overpower the apple's acidity.
If you're using boneless chops, start checking the internal temperature a minute or two earlier. They cook through faster than bone-in.
The sauce is good over steamed jasmine or short-grain rice. Egg noodles also work. A side of sautéed bok choy, roasted cabbage, or steamed broccoli pairs well with both the pork and the sauce.
