Ingredients

Steaks

  • 4 6-ounce filet mignons
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon ground black pepper

Garlic Parsley Butter

  • 1/4 cup unsalted butter (at room temperature)
  • 1 tablespoon chopped fresh parsley
  • 1 clove garlic (grated or minced)
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon ground black pepper

Instructions

  1. Prepare the Garlic Butter: In a mixing bowl, combine the softened unsalted butter with chopped fresh parsley, grated or minced garlic, kosher salt, and ground black pepper. Mix thoroughly until all ingredients are well incorporated.
  2. Shape and Chill Butter: Place the butter mixture in the center of a sheet of parchment paper or plastic wrap. Roll it into a tight log shape and refrigerate for 1 hour to firm up, or place in the freezer for 15 minutes if you need it faster. Once firm, slice the butter log into equal portions to top each cooked steak.
  3. Preheat Air Fryer: Preheat your air fryer to 400°F (204°C) to ensure a hot cooking environment for perfect searing and even cooking of the filet mignons.
  4. Prepare Steaks: Season the filet mignons evenly with kosher salt and ground black pepper on all sides to enhance their natural flavor.
  5. Cook Steaks: Place the seasoned filet mignons in the air fryer basket, ensuring they are spaced apart for even air circulation. Cook for 9-14 minutes total, flipping the steaks halfway through the cooking time to ensure even browning and doneness.
  6. Check Doneness: Use an instant-read thermometer to check the internal temperature of each steak. Aim for 120-125°F for rare, 125-130°F for medium-rare, 133-140°F for medium, 145-150°F for medium-well, or 160°F for well-done according to your preference.
  7. Serve with Compound Butter: Remove the filet mignons from the air fryer and transfer to plates. Immediately top each steak with a slice of the chilled garlic parsley butter, allowing it to melt over the warm steak for extra flavor and moisture.
  8. Enjoy: Serve the steaks hot with your choice of side dishes and enjoy this quick, gourmet meal made effortlessly in the air fryer.

Notes

  • For best results, let the steaks come to room temperature before cooking to ensure even cooking.
  • Adjust cooking time based on steak thickness and preferred doneness level; thicker cuts may require additional time.
  • The compound butter can be prepared a day ahead to save time and enhance flavors.
  • Use an instant-read thermometer to avoid overcooking and achieve perfect doneness.
  • Rest steaks for 5 minutes after cooking to allow juices to redistribute before serving.
