Gather all ingredients. Preheat an outdoor grill for high heat and lightly oil the grate.
Melt butter in a small saucepan over medium-low heat.
Stir in minced garlic and garlic powder. Set aside.
Season both sides of each steak with salt and pepper.
Place steaks on preheated grill and cook 4 to 5 minutes per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C) for medium doneness.
Transfer steaks to warmed plates; brush the tops liberally with garlic butter and allow to rest for 2 to 3 minutes before serving.
