- Overcooking the steak: Cooking the steak too long will make it tough. Use a meat thermometer to check for doneness; aim for medium-rare at 130°F to 135°F.
- Not letting the steak rest: Cutting into steak right after cooking can cause juices to escape. Allow it to rest for about five minutes before slicing to keep it juicy.

- Neglecting the cowboy butter: The cowboy butter adds so much flavor. Don’t skimp on using enough of it during assembly and brushing over the tops.
