Generously season both sides of the steaks with Cajun seasoning, salt, and pepper. Let them sit at room temperature for about 10 minutes.
Prepare the Cajun Butter Sauce
In a small bowl, mix softened butter, minced garlic, Cajun seasoning, and lemon juice until well combined. Set aside.
Heat the Skillet
Heat olive oil in a large skillet over medium-high heat until hot.
Sear the Steaks
Place the seasoned steaks in the skillet and sear for about 4-5 minutes on each side for medium-rare, adjusting the time based on your desired doneness.
Add the Cajun Butter
During the last minute of cooking, spoon the Cajun butter sauce over the steaks, allowing it to melt and infuse the meat with flavor.
Rest the Steaks
Remove the steaks from the skillet and let them rest for 5 minutes to allow the juices to redistribute.
Garnish and Serve
Slice the steaks against the grain, drizzle with any remaining Cajun butter, and sprinkle with fresh parsley before serving.
