Ingredients
  

  • 6 pounds Filet mignon
  • A pinch of salt
  • A pinch of rose pepper
  • 3 ounces Olive oil (not virgin olive oil, that burns!)
  • 3 ounces Unsalted butter

Instructions
 

  • Rub salt and pepper onto the steak the night before. Put the filet mignon into a freezer bag or airtight container overnight. At least 30 minutes before beginning the cooking process, let it come to room temperature. 
  • Preheat the oven to 350 degrees.
  • Using an oven-proof cast iron skillet, with smoking hot oil and butter, create a deep searing on each side for 3–4 minutes on very high heat.
  • Flip them over and keep basting them while searing. This creates a deep brown crust that seals in the moisture perfectly while oven-baking.
  • Transfer the filet mignon in the oven-proof cast iron skillet into the preheated oven without covering it, and bake it for 35 minutes.
  • Remove the filet mignon and let it rest for 10 minutes before proceeding. This is a must for a perfect dish!
  • Always slice them against the grain; otherwise, they will be chewy. Serve them with dry white wine, some mashed potatoes, grilled mushrooms, fried sweet potatoes, or glazed potato dumplings.
