Step 1

Using a knife, score the steak on both sides with shallow cuts across the grain in a criss-cross pattern. Season both sides with salt and black pepper.

Step 2

In a 2-cup measuring cup, whisk together the red wine, olive oil, Worcestershire sauce, garlic, Dijon, and rosemary. Pour the mixture into a plastic zipper bag, then place the steak in the bag and massage the marinade into the meat. Refrigerate for 4-8 hours.

Step 3

Remove the steak from the bag and place it on a cutting board, then pour the marinade in a saucepan and set it aside.

Step 4

Pat the steak dry with paper towels. Let it rest and come to room temperature for 30 minutes.

Step 5

Preheat the air fryer to 400 degrees F. Place the steak inside, and cook for 5-7 minutes on each side, flipping once. (5 mins each side for 130 degrees/med-rare)

Step 6

Remove the steak and allow it to rest on a cutting board for 10 minutes, then slice thinly against the grain.

Step 7

While the steak rests, make the sauce (optional). Add beef broth to the saucepan with the marinade. Bring it to a boil over medium-high heat, then reduce the heat and simmer until the sauce thickens. Stir in the butter, taste, and season if necessary.
