My husband used to say we could only get a good filet at fancy steakhouses. Then I learned the cast iron method and he never said that again. This is now our go-to anniversary dinner — two thick filets, a bottle of wine, and a movie at home. Better than any restaurant, and I can wear sweatpants.

Ingredients

  • 2 filet mignon steaks (8 oz each, 1.5 inches thick)
  • 2 tablespoons avocado oil
  • Coarse sea salt
  • Freshly cracked black pepper
  • 4 tablespoons ghee (or grass-fed butter if not strict paleo)
  • 3 cloves garlic, smashed
  • 3 sprigs fresh thyme
  • 2 sprigs fresh rosemary

For the Herb Butter

  • 4 tablespoons ghee, softened
  • 1 tablespoon fresh parsley, minced
  • 1 teaspoon fresh thyme, minced
  • 1 clove garlic, minced
  • Pinch of sea salt

Instructions

  1. Make herb butter: Mix softened ghee with parsley, thyme, garlic, and salt. Roll into a log using plastic wrap. Refrigerate until firm.
  2. Bring to room temp: Remove steaks from fridge 45 minutes before cooking. Pat completely dry with paper towels. Season generously with salt and pepper on all sides.
  3. Get the pan screaming hot: Heat a cast iron skillet over high heat for 5 minutes. Add avocado oil.
  4. Sear: Place steaks in pan — do not move them. Sear 3-4 minutes until a dark crust forms. Flip once.
  5. Baste: Add ghee, garlic, thyme, and rosemary to the pan. Tilt pan and baste steaks with the melted ghee for 2 minutes.
  6. Rest: Remove steaks when internal temp is 125°F (medium-rare). Rest 5 minutes. Top with a slice of herb butter before serving.

Tips

  • Dry steaks = better crust: Moisture is the enemy of a good sear. Pat them bone dry.
  • Use a thermometer: 120°F for rare, 125°F for medium-rare, 135°F for medium.
  • Rest time matters: Cutting too soon releases all the juices. Patience pays off.

Pan-seared filet with herb butter — felt like a steakhouse experience at home. Worth every penny on good meat.

I love how the flavors develop in this pan-seared filet mignon with herb butter. Each bite is a little different and it just keeps getting better.
