Instructions

  1. Step 1: Remove the 8 oz filet mignon from the fridge 30 minutes before cooking. Pat dry and season both sides with 1 tsp kosher salt and 1 tsp black pepper.
  2. Step 2: Heat 1 tbsp olive oil in a heavy skillet over medium-high heat until shimmering. Add the steak and sear for 4 minutes on each side for medium rare.
  3. Step 3: In the last 2 minutes of cooking, add 2 tbsp unsalted butter, 2 sprigs fresh rosemary, and 2 smashed garlic cloves to the skillet. Tilt the pan and spoon the melted butter over the steak repeatedly to baste.
  4. Step 4: Remove the steak and tent with foil to rest. Discard rosemary and garlic from the pan.
  5. Step 5: Add 1/4 cup beef broth to the skillet and simmer for 2-3 minutes, scraping up any browned bits to create a pan sauce.
  6. Step 6: Pour the rosemary sauce over the rested filet mignon slices and serve immediately.
