Ingredients:

  • 2 (6 oz / 170g) Ahi tuna steaks
  • 1 tbsp (15ml) avocado oil
  • 1 tsp (6g) kosher salt
  • 1/2 tsp (3g) cracked black pepper
  • 3 tbsp (42g) unsalted butter
  • 3 cloves (15g) garlic, smashed and minced
  • 1 tbsp (15ml) fresh lemon juice
  • 1 tbsp (4g) fresh parsley, finely chopped

Instructions:

  1. Pat the tuna steaks completely dry using paper towels. Note: Moisture creates steam, which stops the crust from forming.
  2. Season generously with salt and cracked black pepper on all sides, including the edges.
  3. Heat the avocado oil in a cast iron skillet over high heat until it just begins to smoke.
  4. Carefully place the tuna in the pan.
  5. Sear for 1.5 to 2 minutes without moving them until a dark brown crust forms.
  6. Flip the steaks and sear for another 1.5 to 2 minutes for medium rare.
  7. Reduce the heat to medium.
  8. Add the butter and minced garlic. Wait 30-60 seconds until the butter foams and smells nutty.
  9. Tilt the pan and spoon the sizzling garlic butter over the tuna repeatedly.
  10. Finish with a squeeze of lemon juice and a sprinkle of fresh parsley.
