How to Make Filet Mignon

Season the Filets: Season both sides of the filet mignon with salt and pepper.

Sear the Steaks: Heat a cast iron skillet over high heat until lightly smoking. Add the olive oil and sear the filets for 4 minutes per side, until a nice crust forms.

Add the Blue Cheese Butter: Top each filet with a slice of blue cheese butter. Broil on high for 2–3 minutes, until melted.

Rest and Serve: Let the filet mignon rest for 5 minutes before serving. For medium-rare, the internal temperature should be 130–135°F. Serve with extra melted blue cheese butter if desired. 🥩💙

Tips I Found Helpful 💙

  • Bring the steaks to room temperature before cooking for more even results.
  • Get the skillet very hot before adding the filets to create a good sear.
  • Don’t move the steaks around while they’re searing so that crust can develop.
  • Use a meat thermometer to check the internal temperature without overcooking.
  • Let the filet rest for 5 minutes before cutting so the juices stay in the meat.
