Add flour, garlic and onion powder, salt, cayenne and black pepper into a shallow dish and stir to combine. Pat the pork chops dry with paper towels and then dredge in the flour mixture.
Heat large sauté pan over medium high heat and add oil to the pan.
When the oil is hot add the pork chops to the pan in a single layer and fry for 3 minutes on each side until golden brown.
Remove the pork chops from the pan.
Add two tablespoons of seasoned flour mixture to the pan drippings. Mix the flour into the fat to dissolve. Pour in the chicken broth. Let the liquid cook down for 5 minutes to reduce and thicken slightly.
Stir in the buttermilk and return the pork chops to the pan, covering them with the sauce.
Simmer for 5 minutes until the pork is cooked through.
Season with salt and pepper and garnish with chopped parsley before serving.
