Preheat oven to 375 degrees F.
Heat the oil in a frying pan. Season pork chops with salt, pepper, and garlic powder, and add to the pan.
Brown pork chops on both sides, then set aside.
Add hash browns to the same pan, and brown on both sides.
Mix cream of mushroom soup, milk, and sour cream. Add to a 9" X 13" glass casserole dish. Break up the hash browns and add to the casserole dish, along with 1 cup shredded cheese, and 1 cup fried onions. Mix until all the ingredients are combined.
Smooth out the potato mixture, and cover with the pork chops. Cover with aluminum foil and bake for 30 minutes.
Remove casserole dish from the oven. Carefully remove the foil. Sprinkle with the remaining ½ cup of French fried onions, and ½ cup of shredded cheese.
Bake, uncovered until the cheese is melted, and the fried onions are browned.
Serve the pork chops with a helping of the cheesy potatoes on the side. Enjoy!
