📝 About This Recipe

This recipe transforms a classic cut of beef into a restaurant-quality masterpiece through the art of the perfect sear and butter-basting. By utilizing a heavy cast-iron skillet and aromatic herbs, we unlock a deep, caramelized crust while maintaining a tender, juicy interior. It is a celebration of rich, beefy flavor elevated by the fragrance of garlic, rosemary, and thyme.

🥗 Ingredients

The Steaks

  • 2 pieces Top Sirloin Steaks (10-12 oz each, at least 1.5 inches thick)
  • 1.5 tablespoons Kosher Salt (coarse grain)
  • 1 tablespoon Black Peppercorns (freshly cracked)
  • 2 tablespoons Avocado Oil (or any high-smoke point oil)

The Basting Aromatics

  • 4 tablespoons Unsalted Butter (high-quality European style preferred)
  • 4 pieces Garlic Cloves (peeled and smashed)
  • 2 sprigs Fresh Rosemary
  • 3 sprigs Fresh Thyme
  • 1 piece Shallot (halved)

Finishing Touches

  • 1/2 teaspoon Flaky Sea Salt (such as Maldon)
  • 1 tablespoon Fresh Parsley (finely chopped)

👨‍🍳 Instructions

  1. 1

    Remove the sirloin steaks from the refrigerator at least 45 minutes before cooking to allow them to come to room temperature; this ensures even cooking throughout the meat.

  2. 2

    Use paper towels to pat the steaks extremely dry on all sides. Moisture is the enemy of a good crust, so ensure the surface is bone-dry.

  3. 3

    Season the steaks generously with kosher salt and freshly cracked black pepper on the tops, bottoms, and the thick side edges.

  4. 4

    Place a heavy cast-iron skillet over high heat. Allow the pan to heat until it is just starting to wisps of smoke appear.

  5. 5

    Add the avocado oil to the pan, swirling to coat the surface evenly. It should shimmer and move like water.

  6. 6

    Carefully lay the steaks into the pan, laying them away from you to avoid oil splatter. Press down slightly with a spatula to ensure full contact.

  7. 7

    Sear the first side undisturbed for 3-4 minutes until a deep, dark brown crust has formed.

  8. 8

    Flip the steaks using tongs. Immediately reduce the heat to medium-high and add the butter, smashed garlic, rosemary, thyme, and shallot to the pan.

  9. 9

    As the butter melts and begins to foam, tilt the pan slightly so the butter pools at the bottom with the aromatics. Use a large spoon to continuously pour the hot, flavored butter over the steaks.

  10. 10

    Continue basting for another 3-4 minutes. Use an instant-read thermometer to check for doneness: 130°F (54°C) for medium-rare or 140°F (60°C) for medium.

  11. 11

    Using tongs, stand the steaks on their sides to sear the fat cap and edges for about 30 seconds per side.

  12. 12

    Transfer the steaks to a warm plate or cutting board. Pour the remaining pan butter and aromatics over them and let them rest for 8-10 minutes.

  13. 13

    Slice the steak against the grain into thick strips, sprinkle with flaky sea salt and fresh parsley, and serve immediately.

💡 Chef's Tips

Always use a cast-iron skillet for the best heat retention and crust development. Never skip the resting period; it allows the muscle fibers to relax and reabsorb the juices. If the butter begins to smoke excessively or turn black, slightly lower the heat to maintain a nutty brown color. For a cleaner flavor, use a high-smoke point oil for the initial sear and only add butter halfway through to prevent burning.

🍽️ Serving Suggestions

Pair with a full-bodied Cabernet Sauvignon or a peppery Syrah. Serve alongside creamy garlic mashed potatoes to soak up the herb butter. Accompanied by honey-glazed roasted carrots or charred asparagus. A side of sautéed wild mushrooms with balsamic reduction complements the beefiness perfectly.
