A straightforward and delicious cast iron steak recipe featuring a garlic rosemary butter baste that delivers a juicy, tender, and flavorful steak with a perfect crust.

Ingredients

Scale
  • 1 ribeye or New York strip steak, 1-inch thick, about 10-12 ounces (280-340g)
  • Kosher or sea salt, to taste
  • Freshly ground black pepper, to taste
  • 3 tablespoons (45g) unsalted butter, softened
  • 3 fresh garlic cloves, smashed
  • 23 fresh rosemary sprigs
  • 1 tablespoon (15ml) vegetable oil or high smoke point oil (e.g., avocado oil)

Instructions

  1. Remove the steak from the fridge about 30-45 minutes before cooking to bring it to room temperature. Pat dry with paper towels to remove moisture.
  2. Season both sides generously with salt and freshly ground black pepper.
  3. Preheat a 10-inch cast iron skillet over medium-high heat for about 5 minutes until very hot.
  4. Add 1 tablespoon of vegetable oil to the skillet and swirl to coat.
  5. Place the steak in the skillet and sear undisturbed for 3-4 minutes for medium-rare, adjusting time for thickness.
  6. Flip the steak using tongs. Immediately add softened butter, smashed garlic cloves, and rosemary sprigs to the pan.
  7. Tilt the pan slightly and use a spoon to baste the steak continuously with the melted butter, garlic, and rosemary for about 3 minutes.
  8. Check doneness with an instant-read thermometer: 130Β°F (54Β°C) for medium-rare, 140Β°F (60Β°C) for medium.
  9. Transfer the steak to a plate or cutting board, tent loosely with foil, and let rest for 5-10 minutes.
  10. Slice against the grain and spoon any leftover garlic rosemary butter from the pan over the steak before serving.

Notes

If butter starts to burn during basting, reduce heat slightly. For dairy-free, substitute butter with vegan butter, ghee, or olive oil. Let steak rest to keep it juicy. Use high smoke point oil like avocado oil for searing. Avoid overcrowding the pan; cook one steak at a time.
