Notes

  • 5 pound steaks cook on the grill until they’re medium rare, following this recipe. This is an internal temperature of 130 degrees Fahrenheit. Add 5 degrees for medium, 10 degrees, for well-done, and subtract 5 degrees for rare. Check our Steak Temperature Chart for help.
  • If you want to make some gorgeous diamond grill marks, turn the steak 45 degrees halfway through each side’s grill time like we do in our Grilled New York Strip Steak recipe.
  • If you don’t want a spicy chimichurri sauce, you can leave out the crushed red pepper.
  • If you have a smaller or bigger steak, don’t focus on the time cooked, but the internal temperature. Use a meat thermometer for best results.
