Ingredients:

  • 8 oz sirloin steak
  • 1 tbsp olive oil
  • 1 tsp coarse sea salt
  • 1/2 tsp freshly cracked black pepper
  • 1 tbsp unsalted butter
  • 2 cloves garlic, smashed
  • 1 sprig fresh rosemary

Instructions:

  1. Preheat the oven to 400°F (200°C). Pat the sirloin steak completely dry with paper towels and season all sides generously with 1 tsp coarse sea salt and 1/2 tsp freshly cracked black pepper.
  2. Place an oven-safe skillet over high heat and add 1 tbsp olive oil, heating until the oil just begins to shimmer.
  3. Place the steak in the pan and sear for 2–3 minutes per side without moving it, until a rich brown crust forms.
  4. Transfer the skillet directly into the preheated oven.
  5. Cook for 4–7 minutes. Use a meat thermometer to ensure the steak reaches a safe internal temperature of 145°F (63°C) for medium-rare, pulling the meat from the oven when it is 5°F (3°C) below your target temperature.
  6. During the last 2 minutes of oven time, place 1 tbsp unsalted butter, 2 cloves smashed garlic, and 1 sprig fresh rosemary on top of the steak to infuse.
  7. Remove the steak from the pan and place it on a cutting board to rest for 5–10 minutes to allow juices to redistribute.
