Instructions
 

Preparation

  • Allow the tomahawk steak to come to room temperature for 30–60 minutes before cooking.
  • In a bowl, combine softened butter, minced garlic, rosemary, steak rub, olive oil, salt, and pepper. Mix until smooth.
  • Generously coat the tomahawk steak with the butter rub, ensuring all sides are covered. Let it marinate in the fridge for 30 minutes or overnight.

Grilling the Steak

  • Set up your BBQ for indirect heat and preheat to 110°C (230°F).
  • Place the steak on the cooler side of the grill. Close the lid and cook until internal temperature reaches 47°C (116°F), about 45–60 minutes.
  • Move the steak over direct heat and sear each side for 1–2 minutes until a deep crust forms. Cook to an internal temp of 51°C (124°F) for medium-rare.
  • Remove the steak and wrap loosely in foil. Rest for 5–10 minutes.

Make the Chimichurri

  • In a bowl, mix olive oil, red wine vinegar, garlic, red onion, chili pepper, parsley, basil, oregano, and cilantro.
  • Season with salt and pepper to taste. Let sit for 10 minutes before serving.

Serving

  • Slice the rested tomahawk steak against the grain into thick pieces.
  • Serve with chimichurri spooned over or on the side.

Notes

  • Always use a meat thermometer for best results when cooking thick cuts like tomahawk steaks.
  • Letting the steak rest is crucial to preserve juiciness—don’t skip it.
  • Chimichurri can be made ahead and stored in the fridge for up to 3 days.
