One of the best things about this Air Fryer Filet Mignon with Herb Butter Recipe is how easily you can customize it to suit your tastes or fit what you have on hand. Whether you want to boost the flavor, tweak the herbs, or experiment with sides, this steak is wonderfully adaptable.

Herb Variations: I love switching up the herbs in the garlic butter depending on the season or what’s fresh in my garden. Sometimes I add fresh basil or oregano for a slightly different aroma that pairs beautifully with filet mignon.
Spicy Kick: For a little heat, I like adding a pinch of crushed red pepper flakes or a dash of smoked paprika to the seasoning before air frying. It gives the steak a subtle smoky spicy flavor that’s irresistible.
Butter Alternatives: If you’re watching dairy or just want a different twist, try a compound butter made with olive oil and herbs or a garlic-infused avocado oil butter for a creamy yet lighter topping.

Step 1: Bring Your Steaks to Room Temperature

Start by removing your filet mignon steaks from the fridge about 30 minutes before cooking. This simple step is key to getting even cooking and perfect tenderness. When the steaks aren't cold in the center, they cook more evenly, giving you that melt-in-your-mouth texture.

Step 2: Whip Up Your Garlic Herb Butter

In a small bowl, mix the softened unsalted butter with freshly diced parsley, thyme, rosemary, and minced garlic. This herb butter is the secret to elevating the steak with fresh, fragrant, and savory notes. Once mixed, pop it into the refrigerator so it firms back up and is ready to melt beautifully over the hot steak later.

Step 3: Season Your Steaks to Perfection

Pat your filets dry with paper towels—this helps achieve that gorgeous sear. Rub both sides generously with olive oil, then season evenly with fine sea salt and ground black pepper. Simple seasoning lets the natural flavor of the filet shine while pairing perfectly with the herb butter.

Step 4: Preheat and Cook in the Air Fryer

Preheat your air fryer to 400°F to get it sizzling hot and ready for a great sear. Place the steaks inside without crowding—space is crucial for air to circulate and brown the meat beautifully. Cook for 10 to 11 minutes for medium-rare, flipping halfway through. Use an instant-read thermometer and aim for 130°F internal temperature to ensure juicy, perfectly cooked filet mignon.

Step 5: Rest Your Steaks with Herb Butter

Right after cooking, transfer your steaks to a plate and top each with half of that luscious garlic herb butter. Loosely cover with aluminum foil and let them rest for 10 minutes. This resting period is essential—it lets the juices redistribute inside the steak and allows the butter to melt luxuriously over the meat, making every bite simply divine.

Top Tip

Getting the perfect Air Fryer Filet Mignon with Herb Butter Recipe just right can feel like a gourmet feat, but with these tips, you’ll be slicing into steakhouse-quality tenderness and flavor every time.

Rest Your Steaks: Letting your filet mignon rest for a full 10 minutes after air frying is key—it allows the juices to redistribute and the garlic herb butter to melt perfectly, resulting in melt-in-your-mouth tenderness.
Room Temperature is Your Friend: Taking the steaks out of the fridge 30 minutes before cooking ensures more even cooking throughout, preventing any chilling surprises in the center.
Don’t Overcrowd the Basket: Cooking no more than two steaks at a time keeps the air circulating properly for that beautifully seared crust and juicy interior.
Use a Meat Thermometer: Trusting your thermometer instead of guessing will help you nail your preferred doneness every single time without the stress.

Side Dishes

Make Ahead and Storage

Storing Leftovers

After savoring your filet mignon, tuck any leftovers into an airtight container and refrigerate for up to 3 days. Keeping the garlic herb butter stored separately in the fridge for up to 1 week ensures it stays fresh and ready to top your next steak or even roasted veggies.

Freezing

If you want to save a steak for later, wrap it tightly in plastic wrap and aluminum foil before placing it in the freezer. Properly stored, it can last for up to 2 months. Remember to thaw it gently overnight in the fridge to maintain its tenderness when reheated.

Reheating

Reheat your leftover filet mignon by setting your air fryer to 350°F and warming the steak for about 3-4 minutes. This method brings back that juicy tenderness without overcooking, preserving the savory flavors and that luscious garlic herb butter finish.
