Remove pork chops from the refrigerator and season generously with salt and pepper. Let them sit out for 20 minutes to come to room temperature.
In a small bowl, whisk together orange juice, brown sugar and Dijon mustard. Set aside.
Warm oil in a large skillet over medium heat. Brown pork chops for about 4 minutes per side and check temperature with an instant read thermometer.
Once the internal temperature in the thickest part of the meat reaches 145° F, remove from the pan onto a plate. Let rest for 3 minutes before serving.
While meat is resting, pour out any excess oil from the pan, but do not wipe it clean. Place pan back on medium-high heat and deglaze the pan with the orange juice mixture, scraping up any browned bits. Let boil, while stirring constantly, about 2 minutes or until thickened.
Pour a little bit of glaze over each pork chop and serve immediately.
