Heat olive oil in a skillet over medium-high heat.
Brown the pork chops on both sides to lock in the juices and create a flavorful crust.
Preheat oven to 350°F (175°C).
Lightly spray a 9×13-inch baking pan with non-stick cooking spray. Arrange the sliced potatoes in a single layer at the bottom of the baking pan. Place the browned pork chops on top of the potato layer.
In a medium bowl, combine cream of onion condensed soup, French onion soup mix, and whole milk. Stir until smooth and well blended.
Pour the soup mixture evenly over the pork chops and potatoes.
Bake in the preheated oven for 60 minutes or until the potatoes are tender.
If potatoes need more time, cover the pan with foil and bake an additional 10 minutes.
