These perfectly grilled ribeye steaks are elevated by a zesty cowboy butter made with lemon, garlic, Dijon mustard, red pepper flakes, and fresh parsley.

Grilled steaks are a summer favorite, and before the season ends I wanted to share this easy, flavorful recipe. I originally developed it for Go Bold with Butter, and it’s too good not to pass along.
This is a classic steak done right: a thick ribeye, well-marbled for rich flavor, simply seasoned with salt and pepper, seared until golden and finished to your preferred doneness. A spoonful of savory cowboy butter on top takes the steak to the next level—simple to make but big on flavor.

Choosing the right steak
Ribeye is the recommended cut for this recipe because of its marbling and flavor, but you can use other cuts if you prefer. Choose steaks about 1½ to 2 inches thick so the exterior can develop a good crust without overcooking the interior. Look for visible fat marbling—more marbling means more flavor. USDA Prime cuts have the most marbling and highest quality, while USDA Choice offers good marbling at a lower price point.
