Preheat your grill or grill pan over medium-high heat.
Season the ribeye steaks generously with salt and pepper on both sides.
In a small bowl, mix together the softened butter, minced garlic, and chopped rosemary until well combined.
Grill the steaks for about 4-5 minutes per side for medium-rare, or until they reach your desired level of doneness.
Remove the steaks from the grill and let them rest for a few minutes.
Top each steak with a generous dollop of the garlic rosemary butter and allow it to melt over the hot meat.
Serve the steaks hot, with any additional butter on the side.
