For a creamier sauce, stir in 1/4 to 1/3 cup sour cream or plain Greek yogurt at the very end of cooking, off the heat, to keep it from curdling. If you prefer bone-in pork chops, use 4 medium bone-in chops and add about 30 minutes to the LOW cook time, checking for tenderness. To deepen the onion flavor, you can add 1 small sliced onion on top of the pork before spooning over the soup mixture. For a slightly less rich version, replace the cream of mushroom soup with an extra 1/2 cup beef broth and 1 tablespoon cornstarch whisked into the French onion soup; the sauce will be a bit lighter but still flavorful. If you like a browned finish, transfer the cooked chops to a baking dish, spoon some sauce over them, and run under the broiler for 2 to 3 minutes before serving. Leftovers reheat well on the stovetop over low heat with a splash of water or broth to loosen the sauce.
