Ingredients

  • 4 filet mignon, about 6-8 oz each
  • Kosher salt
  • Freshly ground black pepper
  • Neutral oil
  • Flaky sea salt optional

Instructions

  • Bring the steaks to room temperature. Pat steaks dry with a paper towel, then place them on a parchment-lined rimmed baking sheet. Allow to sit at room temperature for at least 15 minutes. Preheat oven to 225°F (107°C).
  • Optional but helpful: place the steaks on a wire rack set inside the sheet pan for better air circulation and a more even cook.
  • Season the steaks. Sprinkle each steak liberally on all sides with Kosher salt. About 2 teaspoons per filet. It looks like a lot, but meat can handle a good amount of salt. Season on all sides with (a smaller amount of) freshly ground black pepper, as much as you like.
  • Cook the steaks. Place the filets into a preheated oven and cook according to desired doneness. We recommend 25 minutes for medium rare, with an internal temperature of 120°F. (49°C) If you prefer rare, check after 20 minutes. If you prefer steak more cooked, check it after 30 minutes.
  • Regarding temperature: I pull early because the sear adds approximately 5-10°F to the final temperature.
  • Heat a cast iron skillet. Allow the filets to rest while you heat a cast iron skillet over high heat. When it begins to smoke, about 5 minutes later, add 1 Tbsp neutral oil.
  • Sear the steaks. Place steaks in the hot skillet, then cook for about 2 minutes total, flipping the steaks every 15-20 seconds until a crust has formed.
  • Allow the meat to rest. Let the steaks sit for 5-10 minutes to rest, then slice and finish with a sprinkle of flaky sea salt.

Notes

  • Make ahead: Salt filet mignon up to 24 hours ahead and refrigerate uncovered to dry brine. Bring to room temp before cooking.
  • Storage: Refrigerate leftovers up to 3 days.
  • Reheat: Warm in a 250°F / 120°C oven for 15–20 minutes or briefly in a skillet with butter. Skip the microwave.
  • Freezing: Freeze cooked steak up to 3 months. Cool completely, wrap tightly, and thaw overnight in the fridge before reheating.
