Herb Swap: I love experimenting with fresh herbs—try swapping out rosemary and thyme for basil and oregano in the herb butter for a bright, Italian-inspired flavor.
Dairy-Free Delight: Using vegan butter keeps this recipe fully dairy-free without sacrificing the rich, creamy finish. Perfect for those with lactose intolerance or plant-based diets.
Spice It Up: Add a pinch of smoked paprika or cayenne pepper to the herb butter for a smoky kick that pairs beautifully with the tender filet mignon.
Garlic Freshness: For an even bolder garlic punch, try swapping garlic powder for freshly minced garlic in the butter if you’re not in a rush.

Step-by-Step: How I Make Air Fryer Filet Mignon with Herb Butter Recipe

The image shows three steps of preparing two steaks. The first step has two raw red steaks on a white plate, sprinkled with coarse black pepper and salt, sitting on a white marbled surface. In the second step, the raw steaks are placed separately inside a black air fryer basket, maintaining their red color and seasoning visible on top. The third step displays the same two steaks in the air fryer basket, now cooked to a brown color with grilled textures and visible seasoning on the surface. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Bring Everything to Room Temperature

Start by letting your filet mignon steaks and butter sit out for about 30 minutes until they reach room temperature. This simple step makes a world of difference—it helps the steaks cook evenly and ensures the herb butter is soft enough to blend beautifully.

Step 2: Whip Up the Garlic Herb Butter

In a bowl, mix the softened butter with your fresh rosemary, thyme, garlic powder, and salt. Use a fork to really work those flavors together until well combined. Then, scoop the butter onto a piece of parchment paper and shape it into a neat log by rolling and folding the paper around it. Pop it in the fridge to chill while you prepare the steaks—this makes slicing a cinch when serving.

Step 3: Season the Steaks Generously

Brush both sides of your filet mignon steaks with olive oil to help the seasoning stick and develop a beautiful crust. Then, season generously with salt and pepper on each side. Don’t be shy—this is what brings out the steak’s incredible flavor!

Step 4: Air Fry to Perfection

Place the steaks carefully into your air fryer basket in a single layer. Set your air fryer to 400°F and cook for 10 minutes to achieve a perfect medium-rare steak. If you prefer your steak cooked differently, here’s a quick guide by temperature: 120°F for rare, 130°F for medium rare, 140°F for medium, 150°F for medium well, and 160°F for well done. Use a meat thermometer to check the temp so you nail your ideal doneness every time.

Step 5: Let It Rest and Serve

Once your steaks come out of the air fryer, let them rest for 3-5 minutes. This allows the juices to redistribute, giving you a tender and juicy bite. Then, slice a generous pat of the chilled garlic herb butter and place it on top of each filet. Watch as it slowly melts over the warm steak, elevating every bite with rich, savory flavor.

Top Tip

Mastering this Air Fryer Filet Mignon with Herb Butter Recipe is all about a few thoughtful steps that elevate your steak to restaurant-worthy perfection without fuss.

Room Temperature Steaks: Letting your filets come to room temperature before cooking ensures even doneness and juicier results—don’t skip this! It really makes a difference.
Prep Your Herb Butter Ahead: Making the garlic herb butter early and chilling it in a rolled log makes it easy to slice perfect rounds and adds a fresh, vibrant touch to your steak right off the air fryer.
Use a Meat Thermometer: Rely on a meat thermometer instead of guesswork for perfectly cooked steak every time. It’s a game changer for air frying!
Rest Your Steak: Don’t rush serving—letting the steak rest 3-5 minutes keeps it juicy as those flavorful juices redistribute inside the meat.

How to Serve Air Fryer Filet Mignon with Herb Butter Recipe

The image shows a white plate with a serving of medium-rare steak sliced into two pieces on the right side, topped with a small dollop of melting herb butter that has a light yellow color and some green flecks. Next to the steak is a baked potato with the skin intact, opened slightly to reveal soft white potato inside and melted butter on top. On the left side of the plate is a bunch of roasted asparagus with a bright green color and some charred spots. A small sprig of fresh thyme lies beside the steak for garnish. In the background, there is a hint of another plate with similar food. The entire scene is set on a white marbled surface. photo taken with an iphone --ar 2:3 --v 7

Garnishes

Enhance your filet mignon with a sprinkle of freshly chopped parsley or chives for a pop of color and a bit of freshness. A light drizzle of balsamic glaze can also add a subtle tang to contrast the rich herb butter. For something extra, roasted garlic cloves on the side underline the garlic notes beautifully.

Side Dishes

This steak pairs wonderfully with creamy mashed potatoes, roasted asparagus, or garlic sautéed green beans. For a lighter option, a crisp arugula salad with lemon vinaigrette balances the richness perfectly. Don’t forget a crusty bread to sop up all that delicious melted garlic herb butter!

Make Ahead and Storage

Storing Leftovers

Store any leftover filet mignon and herb butter separately in airtight containers in the refrigerator. Your cooked steak will stay fresh for up to 3 days, while the herb butter can last about a week chilled.

Freezing

You can freeze cooked filet mignon wrapped tightly in plastic wrap and foil for up to 2 months. Freeze the garlic herb butter log separately for up to 3 months. Thaw both in the refrigerator overnight before reheating or serving.

Reheating

Reheat your filet gently in a low oven (about 250°F) for 10-15 minutes until warmed through to avoid drying out. Add a fresh slice of your chilled herb butter on top right after reheating for that same melt-in-your-mouth finish.

Frequently Asked Questions:

Can I make the garlic herb butter ahead of time?

Absolutely! The garlic herb butter can be made in advance and refrigerated as a log. Just slice off rounds when ready to serve. It actually tastes better after the flavors meld for a few hours.

How do I know when my filet mignon is perfectly cooked in the air fryer?

Using a meat thermometer is the best way: 120°F for rare, 130°F for medium rare, 140°F for medium, and so on. This Air Fryer Filet Mignon with Herb Butter Recipe includes specific timing guidelines, but temps ensure precision.

Can I use vegan butter in this recipe?

Yes! Swap in your favorite vegan butter to keep it dairy-free without sacrificing flavor or texture in the herb butter.

What if I prefer my steak well done?

No problem. Just increase the air frying time to about 14 minutes and check with a meat thermometer to reach 160°F for well done. Keep in mind the steak will be less juicy but still delicious topped with herb butter.
