Start by preheating your grill or stovetop skillet over medium-high heat.
Season the ribeye steaks generously on both sides with salt and pepper.
In a mixing bowl, combine the softened butter, minced garlic, parsley, chives, Dijon mustard, smoked paprika, Worcestershire sauce, and lemon zest. Mix until well blended.
Once the grill or skillet is hot, place the steaks on it. Cook for about 4–5 minutes on one side without moving them to get a nice sear.
Flip the steaks and cook for an additional 4–5 minutes for medium-rare, or adjust the time according to your preferred doneness.
Remove the steaks from the heat and let them rest for 5 minutes.
While the steaks are resting, take the cowboy butter mixture and divide it into portions. Place a dollop on top of each steak.
Allow the butter to melt over the steaks as they rest for an extra flavorful finish.
Notes
Serve the steaks on a wooden cutting board with the melted cowboy butter glistening on top, and garnish with additional chopped herbs for a rustic look.
