This tender and juicy air fryer filet mignon cooks up in under 15 minutes and requires minimal prep! Serve it with your favorite sides for the perfect quick and easy meal.
Allow steaks to sit out of the fridge for about 15-20 minutes to get to room temperature before cooking.
Make garlic butter, if using, by combining softened butter with garlic, parsley and salt. Mash the mixture together until combined. Set aside.
Combine salt, pepper, garlic and onion powder and thyme in a small bowl. Rub seasonings on all sides of the steak.
Spray air fryer basket with avocado oil and preheat to 400° F.
Place steak into your air fryer basket and cook until the steaks have reached your desired level of doneness. You can use a meat thermometer to ensure the right temperature. We prefer medium steaks (with an internal temp of 140°F) and cook the steaks for 6 minutes, flip then cook for an additional 6 minutes. If you prefer medium-rare, cook the steaks for less time and for a more well done steam, add some additional time.
After cooking, allow steak to rest before cutting, about 5 minutes. Top with a pat of garlic butter, if desired and enjoy.

These times are based on a 1.5-inch thick filet. If the steak is thicker or thinner, adjust by 1-2 minutes accordingly.
Resting: Let the steak rest for 5 minutes after air frying to allow juices to redistribute and for the temperature to rise slightly.
Thermometer: Use a meat thermometer to check the internal temperature, aiming for slightly under your target, as the steak will continue to cook slightly while resting.
