Pat the pork chops dry with kitchen paper, then season generously with salt, pepper, and 1/2 tbsp of Cajun seasoning.
Heat the olive oil in a large frying pan over a high heat. Sear the pork chops for 3 to 4 minutes on each side until deeply golden. Use tongs to crisp up the fat around the edge too. Remove from the pan and set aside.
Reduce the heat to medium. Add the onion and cook for 5 minutes until softened.
Stir in the garlic, remaining Cajun seasoning and the smoked paprika. Cook for 30 seconds until fragrant.
Pour in the chicken stock, scraping up all the caramelised bits from the bottom of the pan. Simmer for 2 to 3 minutes to reduce slightly.
Pour in the double cream and simmer gently for 3 to 4 minutes until the sauce thickens.
Return the pork chops to the pan and spoon the sauce over them. Simmer for another 4 to 5 minutes until the pork is cooked through and the sauce is rich and silky.
Stir through the chopped parsley, taste for seasoning, then serve with buttery mashed potato, and some greens.
