Instructions

  1. Step 1: Pat the ribeye steak dry with paper towels, then season both sides evenly with 1.5 tsp coarse sea salt, 1 tsp black pepper, and 1 tsp garlic powder.
  2. Step 2: Combine 3 tbsp fresh thyme leaves, 2 tbsp fresh rosemary, and 1 tsp garlic powder in a small bowl; press firmly onto both sides of the steak to create a herb crust.
  3. Step 3: Heat a cast-iron skillet over high heat until smoking, then add the steak. Sear undisturbed for 3 minutes until a deep brown crust forms, then flip and sear for 2 minutes for medium-rare.
  4. Step 4: Reduce heat to medium, add 3 tbsp unsalted butter to the skillet, and baste the steak with melted butter for 2 minutes, tilting the pan to coat evenly.
  5. Step 5: While steak rests, boil potatoes until fork-tender (20-25 minutes), then drain. Mash with 1/2 cup heavy cream, 1/4 cup whole milk, and 1 tbsp truffle oil until smooth and creamy.
  6. Step 6: Let steak rest for 10 minutes before slicing, then serve with a generous dollop of truffle mashed potatoes.
