Air Fryer Flank Steak

1. Using a sharp knife, score the steak on both sides with shallow cuts (¼") across the grain in two directions. You will have a criss cross effect. (See photo in post)
2. Season the steak on both sides with pepper.
3. Whisk together all of the marinade ingredients.
4. In a glass bowl or a re-sealable freezer bag, submerge the steak in the marinade.
5. Refrigerate and allow the steak to marinate at least four hours or up to 8 hours.
6. Remove the steak from the marinade and set the marinade aside if using it to make the optional red wine sauce. If not, discard the marinade. Pat the steak dry with paper towels and allow it to come to room temperature, about 30 minutes.
7. Lightly oil the cooking surface in your air fryer.
8. Preheat the air fryer to 400°
9. Cook the steak 5 minutes on each side, flipping only once.
10. Remove the steak and allow it to rest on a cutting board 5-7 minutes.
11. Slice the steak diagonally, across the grain into thin slices.
12. Serve with Red Wine Sauce (optional, see below)

Red Wine Sauce

1. Pour marinade and beef broth into a skillet. Bring to a boil, then reduce heat and simmer until sauce reduces and thickens. Stir in butter one piece at a time. Taste and add salt and pepper if necessary.
