Take the steaks out of the refrigerator 30 minutes before cooking to bring them to room temperature.
Season both sides generously with salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat.
Sear the steaks for about 3-4 minutes per side until they reach your preferred doneness.
Remove the steaks from the skillet and set aside to rest.
Reduce the heat to medium. In the same skillet, add butter and minced garlic. Cook for 1 minute until fragrant.
Pour in the beef broth and simmer for 2 minutes.
Stir in the heavy cream and Dijon mustard. Cook for another 2-3 minutes until the sauce thickens.
Return the steaks to the skillet and spoon the sauce over them.
Garnish with chopped parsley and serve hot.
