Season the pork chops on both sides with salt, garlic powder, onion powder, and black pepper.
Heat the oil in a large, deep skillet over medium heat. Arrange the pork chops in the skillet leaving some space between them. Cook for 3 minutes to brown. Turn and cook another 2-3 minutes to brown the other side.
Remove the skillet from the heat and transfer the pork chops to a plate. Loosely cover with foil to keep warm, or place in the microwave or oven to keep away from drafts.
Do not wash or wipe the skillet. Place it back over medium heat and add the butter. When it’s melted add the onions. Cook for 2-3 minutes, stirring frequently, until they start to soften and turn a light golden color.
Add the flour to the onions and stir to combine. Cook for 1-1½ minutes, stirring constantly, to cook off the raw flour taste.
Pour in the French onion soup and chicken broth while stirring and gently scraping any bits off the bottom of the pan. Bring the sauce to a simmer.
Return the pork chops and any juices collected on the plate back to the skillet. Cover and simmer for 10-15 minutes, or until the largest pork chop reaches 145°F at its thickest part. Turn the chops halfway through cooking. Keep the sauce at a simmer, raise or lower the heat as needed.
Lower the heat to low. Place a slice of provolone cheese over each pork chop. Cover the skillet and cook for 1-2 minutes or until the cheese is melted.
Serve with mashed potatoes, vegetables, rice, bread, or your favorite side dishes.
