  • 2 6-ounce filet mignon, about 3/4" thick, room temperature
  • 1 teaspoon kosher salt + 1 teaspoon pepper
  • 1 tablespoon avocado oil

Herb Butter

  • 2 tablespoons grass fed butter or ghee for Whole30
  • 2 teaspoons finely chopped herbs rosemary, thyme, parsley, chives would all be great!
  • 1/4 teaspoon kosher salt


  • Preheat your cast iron skillet over medium heat for 5 minutes.
  • Pat your filet mignon completely dry, and season both sides with salt and pepper.
  • When your pan is heated, add the avocado oil. Sear the first side for 2 minutes until a brown crust forms. Do not move the steaks at all while it is searing. Flip, and cook another 2 minutes.
  • Use an instant read meat thermometer to check the temperature of the very center of the steaks. Remove the steaks when they are 120ºF for medium rare. Rest the steaks for 8-10 minutes to allow the juices to reabsorb.
  • While the steaks are resting, make the herb butter. In a small bowl, combine the ghee, herbs, salt + pepper. Stir to combine.
  • Top the rested steaks with 1 tablespoon herb butter.


Steak: My favorite place to get grass-fed steaks is ButcherBox, which I highly recommend, or Belcampo! (You can use code TASTESLOVELY10 for 10% off your Belcampo order)
