Pat the pork chops dry and season lightly with salt and pepper.
Heat the oil in a skillet over medium-high heat. Sear the chops 2–3 minutes per side until nicely browned. (This gives them color and improves the gravy.)
Place the seared chops in the slow cooker.
In a bowl, mix the brown sugar, ½ cup soy sauce, condensed soup, and garlic. Pour over the chops.
Cover and cook on low 6–8 hours or high 3–4 hours, until the chops are tender.
Optional thickening: Mix 1–2 tablespoons cornstarch with a little cold water. Stir into the sauce and cook on high for 15–20 minutes until thickened.
Serve over rice, pasta, or mashed potatoes.
