Take the pork chops out of the fridge 15-30 minutes prior to starting the recipe if possible. Pat them dry and season them with some salt & pepper.
Crush the peppercorns either by placing them in a ZipLoc bag and then using a rolling pin, heavy skillet, or meat mallet to smack them, or use a pestle and mortar. You want them to be somewhat intact vs. totally obliterated. The larger the pieces, the more peppery they will taste.
Add the olive oil and 1 tablespoon of the butter to a skillet over medium-high heat. Let the pan heat up for a few minutes, and once it's hot, cook the pork chops for 3-5 minutes/side or until golden (3 minutes for thinner chops and 5 minutes for pork chops up to 1" thick). Once the pork chops are done searing, transfer them to a plate.
Take the skillet off the heat for about a minute to let it cool down a bit.
Over medium heat, add the remaining butter and shallots to the skillet and sauté for about 4-5 minutes or until softened and lightly browned.
Add the brandy to the skillet and let it bubble for about 1-2 minutes (it should reduce a lot).
Add the beef broth and peppercorns to the skillet and let it simmer for 2-3 minutes.
Meanwhile, make a cornstarch slurry by combining the cornstarch with 2 teaspoons of cold water in a small bowl.
Pour in the cream and cornstarch slurry and give it a stir.
Add the pork chops (and any plate juices) back in and cook for another 3-5 minutes or until the sauce has thickened up a bit more and the pork chops are cooked through (145F minimum).
Sprinkle the parsley over top, season with salt as needed, and enjoy.
