🍳 Step-by-Step Instructions

  1. Remove steaks from refrigerator 30 minutes before cooking to bring to room temperature. Pat completely dry with paper towels.
  2. Season steaks generously on all sides with coarse kosher salt and cracked black pepper.
  3. Heat a heavy cast iron skillet over high heat until smoking hot. Add cooking oil.
  4. Place steaks carefully in skillet. Sear undisturbed for 2-3 minutes to develop a deep brown crust.
  5. Flip steaks and cook 2 minutes on the second side.
  6. Reduce heat to medium. Add butter, smashed garlic, rosemary, and thyme to skillet.
  7. Tilt skillet slightly so melted butter pools at one side. Use a large metal spoon to continuously baste foaming butter over steaks for 2 minutes until internal temperature reaches 54°C (130°F) for medium-rare.
  8. Transfer steaks immediately to a cutting board. Pour remaining pan butter over top and let rest undisturbed for 7-8 minutes.
  9. Slice across the grain into thick ribbons and serve warm.

❓ Frequently Asked Questions

How do I know when the steak is medium-rare?
Use a digital meat thermometer inserted into the thickest part: 52-54°C (125-130°F) for medium-rare.
Why did my kitchen get smoky?
High heat searing does generate smoke; use high-smoke point oil and turn your stove exhaust fan on high.
