Preheat oven to 400F.
Brush the pork chops with oil, reserving 1 tbsp of it for the green beans.
In a small bowl, combine salt, pepper, onion powder and paprika. Season the bone-in pork chops with the seasoning. Place on a baking sheet. Add the green beans on the side, drizzle with oil, season with salt and pepper.
Bake pork chops and green beans for 15-20 minutes, until the internal temperature of the pork reaches 145F. The green beans should be soft and cooked through. You may need to take out of the oven the green beans first, if they cook faster and continue cooking the pork.
Let the pork chops rest for 3 minutes, then serve.
