Ingredients

FOR THE FILETS:

  • 2 beef filets, 1 ½" thick (about 6-8 ounces each)
  • 1 tablespoon avocado or canola oil
  • 1 ½ teaspoons Kosher salt
  • 1 teaspoon black pepper

FOR THE OPTIONAL STEAK BUTTER (MAKE AHEAD IF USING):

  • ½ cup unsalted butter
  • ½ teaspoon Worcestershire sauce
  • ¼ teaspoon Kosher salt
  • Pinch black pepper
  • Zest of half a lemon
  • 1 teaspoon freshly chopped thyme leaves
  • 1 tablespoon freshly chopped parsley

Instructions

PREP THE STEAKS:

  • Pat the excess moisture away from the filets using paper towels, set them aside on a work surface, and allow them to sit at room temperature for about 20 minutes to remove the chill. In the meantime, preheat the oven to 400°F.
  • Once the air fryer is ready, drizzle the steaks with the oil and rub all over. Sprinkle with Kosher salt and pepper all over and rub to adhere.

AIR FRY:

  • Add the steaks to the air fryer basket. Cook for 9-15 minutes, depending on the desired doneness of your steaks. Use an instant-read thermometer inserted in the center of your steak for best results. Steak temperature will continue to rise after cooking; remove 5° before the desired temp.
    Rare (120°F): 9-10 minutes → remove at 115°F
    Medium Rare (130°F): 10-11 minutes→ remove at 125°F
    Medium (140°F): 12-13 minutes→ remove at 135°F
    Medium Well (150°F): 13-14 minutes→ remove at 145°F
    Well Done (160°F): 14-15 minutes → remove at 155°F

REST:

  • Remove from the air fryer immediately, top with about a tablespoon of compound butter if desired. Use softened butter immediately, or pre-chilled slices (see below).
  • Tent with aluminum foil and steaks to rest for 10 minutes. Serve and enjoy!

MAKE THE COMPOUND BUTTER:

  • Soften butter in the microwave at 10-second intervals until room temp and easily spreadable but not melted. Mix in the remaining ingredients.
  • Use right away: add a dollop to steak. if using right away.
  • For chilled slices: Spoon butter onto a small sheet of wax or parchment paper, about 4 inches from the edge. Fold the paper over the butter and roll it into a smooth cylinder, about 1 ½ inches thick. Twist the ends in opposite directions, like wrapping a piece of candy. Refrigerate until firm, about 2 hours. Then, slice into rounds and serve.
