Ingredients
- 8 oz top sirloin steak
- 2 tbsp avocado oil
- 2 tbsp unsalted butter
- 1 tsp finely chopped fresh rosemary
- 1/2 tsp garlic powder
- 1/4 tsp sea salt
- 1/4 tsp black pepper
Instructions
- Step 1: Pat the 8 oz steak dry with paper towels, then season evenly with 1/4 tsp sea salt and 1/4 tsp black pepper on both sides.
- Step 2: Heat 2 tbsp avocado oil in a heavy skillet over medium-high heat until shimmering and just smoking, about 2 minutes.
- Step 3: Place the steak in the skillet, pressing lightly to ensure full contact; sear undisturbed for 3 minutes until a deep brown crust forms on the bottom.
- Step 4: Flip the steak, reduce heat to medium, and cook for 3 more minutes for medium-rare, or until the internal temperature reaches 125°F (use a meat thermometer).
- Step 5: Remove steak to a plate, tent loosely with foil, and let rest for 5 minutes. Meanwhile, melt 2 tbsp unsalted butter in the same skillet over low heat, stir in 1 tsp chopped rosemary and 1/2 tsp garlic powder, and simmer for 1 minute until fragrant.
