In a small bowl, combine salt, pepper, garlic powder, onion powder, and smoked paprika.
Season both sides of the pork chops with the spice mixture.
Dredge each pork chop in flour, shaking off any excess. Save the remaining flour.
Heat olive oil in a large skillet over medium-high heat.
Sear pork chops for 3-5 minutes per side until golden brown. Remove from skillet and set aside.
Lower heat to medium and add butter to the skillet.
Add sliced onions and cook for 5-7 minutes until soft and caramelized.
Stir in minced garlic and 1 tablespoon of the reserved flour, cooking for 1 minute.
Slowly whisk in chicken broth and Worcestershire sauce, scraping the bottom of the pan to release browned bits.
Bring the gravy to a simmer until thickened.
Return pork chops to the skillet, cover, and cook for 5 minutes or until internal temperature reaches 145°F.
Garnish with fresh parsley and serve with gravy over the chops.
