Preheat a grill to high heat. Brush the grill grates with oil.
Pat dry the steaks. Season each steak with salt and pepper.
Thread the two steaks onto a large metal skewer. Ensure there is at least an inch apart.
Once hot, grill the coulotte steak, fat cap side down, for 2-3 minutes. Continue grilling each side for 3 minutes, until the internal temperature reaches 135°F for medium-rare.
Remove the steaks from the grill and rest for 5 minutes. Slice and serve with butter.
Notes
No skewers? You can grill the steaks as is, but increase the grilling time by 2-3 minutes.
Doneness: Medium-rare (135°F) is best, but you can cook it to medium (145°F) or medium-well done (150°F) if you prefer.
Grill pan: Works just as well as the grill. Preheat to high heat.
Leftovers: Keep in the fridge for up to 5 days or the freezer for 6 months. Ensure the steaks are covered.
