Ingredients:

  • 1 (16-20 ounce) T-bone steak, about 1-1.5 inches thick (450-570g, 2.5-4cm)
  • 1 tablespoon olive oil (15ml)
  • 1 teaspoon kosher salt (5ml)
  • 1/2 teaspoon freshly ground black pepper (2.5ml)
  • 4 tablespoons unsalted butter, softened (57g)
  • 2 cloves garlic, minced
  • 2 tablespoons finely chopped fresh parsley
  • 1 tablespoon finely chopped fresh thyme
  • 1/4 teaspoon red pepper flakes (optional, 1.25ml)

Instructions:

  1. Pat the steak dry with paper towels. Season generously with salt and pepper. Let sit at room temperature for 30 minutes.
  2. In a small bowl, combine softened butter, minced garlic, parsley, thyme, and red pepper flakes (if using). Mix well and set aside.
  3. Place the cast iron skillet over high heat. Allow the skillet to get screaming hot – you should see a wisp of smoke.
  4. Add olive oil to the hot skillet. Carefully place the steak in the skillet. Sear for 3-4 minutes per side, without moving it, until a deep brown crust forms.
  5. Reduce the heat to medium. Continue cooking, flipping the steak every 2-3 minutes, until it reaches your desired internal temperature.
  6. During the last minute of cooking, add the garlic herb butter to the skillet. Tilt the skillet and use a spoon to baste the steak with the melted butter.
  7. Remove the steak from the skillet and place it on a cutting board. Top with any remaining garlic herb butter from the skillet. Tent loosely with foil and let rest for 5-10 minutes.
  8. Slice the steak against the grain and serve immediately.
