Make It Your Way

This Air Fryer Filet Mignon with Herb Butter Recipe is wonderfully versatile, so feel free to make it your own! Whether you want to experiment with different herbs or adjust the doneness to suit your preferences, there’s plenty of room for personalization while still enjoying that melt-in-your-mouth tenderness and rich garlic herb flavor.

Herb Variations: I love swapping fresh herbs depending on what’s in season. Sometimes I use basil or tarragon instead of rosemary and thyme for a slightly different but equally delicious twist. Fresh dill also pairs beautifully for a bright and savory herb butter.
Garlic Alternatives: For a milder garlic flavor, roasted garlic works perfectly. It softens the sharpness, adding a sweet, mellow depth that complements the filet beautifully.
Butter Tips: For a dairy-free version, try using a plant-based butter mixed with your favorite herbs and garlic. The result is still creamy and flavorful, and you get that beautiful herb infusion without the lactose.
Doneness Preferences: Adjust the cook time between 9 and 14 minutes depending on how you like your steak—rare to well done. Just remember to keep a meat thermometer handy to nail that perfect internal temperature.

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

The image shows one large piece of cooked steak sliced into four thick layers, each with a brown outer crust and a juicy pink center. Three slices are laid flat on a wooden board with a texture of small juices on the surface, and the top slice has a spoonful of chopped garlic and green herbs on it. Several green rosemary sprigs are placed over the steak and around it. To the upper right is a whole garlic bulb with a pale white color and dry skin, all set on a white marbled textured background.

Step 1: Bring Your Steaks to Room Temperature

Before you start, take the steaks out of the fridge about 30 minutes early. This little pause helps the meat cook evenly throughout, avoiding those cold spots inside. You’ll notice the steak feels less cold to the touch, almost like it’s starting to breathe—this sets you up for a consistently juicy finish.

Step 2: Make Your Garlic Herb Butter

In a small bowl, blend softened unsalted butter with fresh parsley, thyme, rosemary, and minced garlic. I like to really mix it well so every bite is infused with those fresh herb oils and garlicky goodness. Pop this mixture into the fridge to firm up while you prep your steaks. This keeps the butter perfectly spreadable but cool.

Step 3: Season and Oil Your Steaks

Pat the steaks completely dry with paper towels—this step helps achieve a beautiful sear. Next, rub each side with olive oil; this not only adds flavor but helps the seasoning stick. Sprinkle half a teaspoon each of fine sea salt and ground black pepper on both sides. Press the seasoning gently into the meat to create a savory crust when cooked.

Step 4: Preheat Your Air Fryer to 400°F

Turn on the air fryer and set it to 400°F. Let it fully preheat—this usually takes a few minutes and ensures the steaks jump straight into a hot cooking environment, so you get that perfect sear and crust without drying out the inside.

Step 5: Cook Your Steaks to Perfection

Place the filet mignon steaks in the air fryer basket without overcrowding so air can circulate freely. Cook for 10 to 11 minutes for medium-rare, flipping the steaks halfway through to get even browning on both sides. Use an instant-read meat thermometer to check for an internal temperature of 130°F—this tells you your steaks are perfectly medium-rare. Adjust the time slightly if you prefer a different doneness as noted in the recipe.

Step 6: Rest and Crown with Herb Butter

When the cooking time is up, transfer the steaks immediately onto a serving plate. Top each one with half of your prepared garlic herb butter. Loosely cover the plate with aluminum foil and let the steaks rest for 10 minutes. This resting period is crucial—it allows the juices to redistribute through the meat and lets the butter melt right into every tender bite.

Top Tip

Mastering the perfect Air Fryer Filet Mignon with Herb Butter Recipe is all about the details. These tips will help you get that melt-in-your-mouth tenderness and rich flavor every single time.

Bring Steaks to Room Temperature: I always take the steaks out 30 minutes before cooking to ensure they cook evenly and stay juicy inside.
Pat Dry for the Best Sear: Drying the surface of the steaks thoroughly before seasoning makes a huge difference in achieving that delightful crust.
Flip Halfway Through: Flipping the steaks at the 5-6 minute mark helps get an even air fryer sear on both sides without drying out the meat.
Rest Your Steak: Resting for 10 minutes is essential. It lets the juices settle and the garlic herb butter melt perfectly, which makes every bite heavenly.

How to Serve Air Fryer Filet Mignon with Herb Butter Recipe

A small clear glass bowl sits on a white marbled surface, holding a single layer of creamy herb butter mixed with small chopped green herbs. The butter looks soft with a slightly rough texture, and bits of herbs are spread evenly throughout. There are faint traces of the butter smeared around the inside of the bowl.

Garnishes

Elevate your dish with a sprinkle of fresh chopped parsley or thyme on top for a pop of color and added freshness. A lemon wedge on the side also adds a nice bright contrast if you crave a little zest.

Side Dishes

Serve your filet mignon with classic sides like garlic mashed potatoes, roasted asparagus, or a crisp green salad dressed with a light vinaigrette. Sautéed mushrooms or a creamy risotto also pair wonderfully, soaking up any extra herb butter.

Make Ahead and Storage

Storing Leftovers

After cooking, store leftover filet mignon in an airtight container in your refrigerator for up to 3 days. Keep your herb and garlic butter separately in the fridge; it will stay fresh for up to one week.

Freezing

While freezing cooked steak isn’t ideal for texture, you can freeze the garlic herb butter in an airtight container or wrapped in plastic wrap for up to 3 months. Just thaw it in the fridge before use.

Reheating

To gently reheat your filet mignon, preheat your air fryer to 350°F and warm the steak inside for 3-4 minutes. This method keeps the steak juicy and prevents overcooking. Add a pat of herb butter just before serving to revive those delicious flavors.

Frequently Asked Questions:

Can I cook more than two filet mignons at once in the air fryer?

It’s best to cook only two steaks at a time to avoid overcrowding. Air needs to circulate to give the filet mignon its perfect sear and even cooking. If you have more, cook them in batches for best results.

How do I know when the steak is medium-rare?

Use an instant-read meat thermometer to check the internal temperature. For medium-rare, it should read 130°F before resting. After resting, the temperature will rise slightly to about 135°F, which is perfect.

Can I use frozen filet mignon for this recipe?

For best results, thaw the filet mignon completely before cooking. Cooking from frozen will result in uneven doneness and may overcook the exterior while the inside remains underdone.

What can I do if I don’t have fresh herbs for the butter?

You can substitute dried parsley, thyme, and rosemary, but use about one-third the amount since dried herbs are more concentrated. Mix them well with softened butter and garlic for a tasty alternative.

I hope this Air Fryer Filet Mignon with Herb Butter Recipe brings a little bit of restaurant magic right into your kitchen.
