Ingredients

  • 4 filet mignon about 6-8 oz each
  • Kosher salt
  • Freshly ground black pepper
  • Neutral oil such as grapeseed, canola oil, or vegetable oil
  • Flaky sea salt optional, for serving

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.
  • Season the steaks. Sprinkle each steak liberally on all sides with Kosher salt. About 2-3 tsp 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 115°F. If you prefer rare, check after 20 minutes. If you prefer steak more cooked, check it after 30 minutes.
  • 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: You can season the filet mignon with kosher salt up to 24 hours in advance. Store uncovered in the fridge to dry brine — this helps enhance flavor and promotes a better sear. Bring to room temperature before cooking.
  • Leftovers will keep for up to 3 days.
  • To gently reheat, place the steak in a low oven (around 250°F) until warmed through, about 15–20 minutes, or reheat slices briefly in a skillet with a bit of butter. Skip the microwave to avoid overcooking.
  • Freezing instructions: Cooked filet mignon can be frozen for up to 3 months. Let it cool completely, then wrap tightly in plastic wrap and foil before placing in a freezer-safe bag. Thaw overnight in the fridge before reheating.
