When thinking about cooking filet mignon in the air fryer, I decided to make it a complete special occasions style meal. I researched which veggies would cook at the same rate as a filet mignon steak. It takes about 15 minutes for cooking steak. It also takes 10-15 minutes to air fry Brussels sprouts and sweet potatoes. So that’s how I decided on my combination. And then to really take it over the top, I created a butter sauce to drizzle over both the steak and the veggies.

Why this recipe works
The constant hot air circulating on all sides in the air fryer cooks protein perfectly. There’s no guess work. Filet mignon can be tricky because it’s such a thick steak but very lean. With little fat in the beef for flavor, filet mignon is almost always served with flavored butter melting on the top.
The air fryer controls the temperature, so as not to overcook the steak. But no extra butter or oil is needed for the cooking process in the air fryer. Meaning you can indulge in the yummy butter sauce drizzled over the filet mignon and veggies after cooking. This meal has a really fancy feel, but it’s ready to eat in just about 20 minutes.
Ingredients for air fryer filet mignon recipe
- Filet Mignon Steaks – For testing purposes, I used a thick 8-ounce filet.
- Veggies – Sweet potatoes and Brussels sprouts cook in about the same amount of time as the steak. You can always skip the vegetables and cook more steaks at once.
- Butter Sauce – I decided on a cowboy style butter sauce for this meal. Flavored with fresh garlic, mustard, fresh herbs and red pepper flakes. But you could add blue cheese crumbles, honey and black pepper to your butter mixture instead.
Instructions for cooking perfect air fryer steak
I like to set my steak out on the counter for about 15 minutes to get a bit of the chill off. I also preheat my air fryer for about 5 minutes. Season both sides of the filet mignon with salt and pepper. Prepare the veggies and drizzle them with a bit of olive oil.
Place both the filet mignon and the veggies in the air fryer basket. Cook at 375 degrees F for about 15 minutes (depending on the brand of your air fryer). The middle of the steak should be cooked to between 140 and 145 degrees F for Medium. I always the check the temperature of my steak with an instant read thermometer.
While the filet mignon and veggies are cooking, melt the butter to make the sauce. Once everything is cooked, drizzle the butter sauce over the top. It’s so delicious!

Kitchen Tips
- I use a Philips XXL Air Fryer in my kitchen
- Digital meat thermometer for checking the temperature of the filet mignon – always check at the thickest part of the steak
- If you prefer your filet mignon cooked to medium rare, check the temperature at about 12 minutes. A medium rare steak is about 130 to 135 degrees F.
Air Fryer Filet Mignon
Equipment
- 1 Air Fryer
Ingredients
- 8 oz filet mignon
- 8 Brussels sprouts
- 1/2 sweet potato
- 2 tbsp butter
- 1 clove garlic minced
- 2 tsp Dijon mustard
- 2 tsp fresh lemon juice
- 1 1/2 tsp fresh thyme
- 1/2 tsp salt
- 1/2 tsp crushed red pepper flakes
Instructions
- Remove the filet mignon from the refrigerator about 15 minutes before ready to cook. Season both sides of the filet with salt and pepper.
- Preheat the air fryer to 375 degrees F about 5 minutes before ready to place the filet and veggies inside.
- Wash both the Brussels sprouts and sweet potato. Remove the outer leaves if necessary from the Brussels sprouts. Trim off the hard bottom stems. Peel the sweet potato and cut into about 1 inch pieces. Reserve the other half for another meal. Drizzle the veggies with a bit of vegetable oil and toss to coat evenly.
- If your air fryer is large enough, you can cook two steaks and add a few more veggies at the same time. Just double the amount of butter sauce.
- Place the seasoned filet and prepared veggies in the preheated air fryer basket. Cook for about 15 minutes, flipping the filet over halfway through.
- Steak is done when the internal temperature is between 140 and 145 degrees F. If some of the outer leaves of the Brussels sprouts get too crispy, just remove them.
- While the filet and veggies are cooking, place the butter and garlic in a microwave safe dish. Microwave for 30 - 45 seconds, or just until butter is melted.
- Whisk in the mustard, lemon juice, thyme, salt and red pepper flakes.
- Place the filet and veggies on a plate. Drizzle them with the butter sauce. Serve.
