Season pork chops on both sides with salt, pepper and thyme.

Heat a large skillet over medium high heat and add the olive oil.

Add pork chops to the pan and sear for 3-4 minutes on each side, until well browned. Remove the pork chops from the pan and cover to keep warm. (They will finish cooking later.)

Make the gravy. Reduce the heat to medium low and add the butter to the skillet.

Add the flour and whisk to combine. Cook the flour mixture for 1 minute, whisking occasionally, to get the raw taste out.

Add chicken broth to the pan slowly and whisk continuously to combine until the mixture is smooth, without any lumps. Sprinkle in the thyme, salt and pepper.

Let the gravy cook over medium-low heat for 3-4 minutes until slightly thickened.

Return the pork chops to the pan and turn to coat them in the gravy. Cover the pan with a lid (or aluminum foil) and cook for 8-10 minutes, until pork chops reach an internal temperature of 135-140.

Remove from heat. Add the Greek yogurt to the gravy and stir to combine.

Serve the pork chops with plenty of gravy over top.
