Ingredients
  

  • 1 bone-in sirloin roast (3-4 lbs)
  • 1 tbsp coarse sea salt
  • 1 tbsp black pepper
  • 2 tsp garlic powder
  • 1 tbsp fresh rosemary (chopped)
  • 1 tbsp avocado oil (for searing)

Instructions
 

  • Pat the roast dry with paper towels. Season generously with salt, pepper, garlic powder, and rosemary. Let sit at room temperature for 30-60 minutes.
  • Preheat oven to 375°F (190°C). Heat avocado oil in a cast-iron skillet over high heat. Sear the roast for 2-3 minutes per side until deeply browned.
  • Transfer to a wire rack in a roasting pan. Roast for 15-20 minutes per pound until internal temperature reaches 135°F (57°C) for medium-rare.
  • Rest for 15+ minutes before slicing against the grain. Serve with pan juices or gravy.
