1-First Step: Start by scoring both sides of the 2 pounds flank steak in a criss-cross pattern. This helps the marinade penetrate deeply, making the meat more flavorful and tender, which is especially useful if you’re cooking for dietary needs like reducing sodium.

2-Second Step: Season the steak with kosher salt to taste and black pepper to taste. I sprinkle it evenly to ensure every bite has that perfect savory kick; this is a great spot to adjust for preferences, like using less salt for low-sodium diets.

3-Third Step: Whisk together the marinade by combining 1 cup dry red wine (or a substitute like balsamic vinegar), 2 tablespoons olive oil, 2 tablespoons Worcestershire sauce, 3 cloves garlic (minced), 1 teaspoon Dijon mustard, and ½ teaspoon dried rosemary in a bowl. Place the steak in a sealed bag with this mixture and let it marinate for 4-8 hours, preferably overnight, to boost tenderness and flavor overnight works wonders for busy schedules.

4-Fourth Step: Remove the steak from the marinade and pat it dry with a paper towel. Let it sit at room temperature for 30 minutes; this step is key for even cooking and can be quickened if you’re in a rush, but don’t skip it for best results with air fryer flank steak.

5-Fifth Step: Preheat your air fryer to 400 degrees F and lightly oil the basket to prevent sticking. Once it’s hot, place the steak in and cook for 5-7 minutes per side, flipping once aim for 5 minutes per side for medium-rare, checking the internal temperature reaches about 130 degrees F for that ideal doneness.

6-Sixth Step: Let the steak rest for 10 minutes after cooking; this allows the juices to redistribute, making your air fryer flank steak even juicier. While it rests, simmer the reserved marinade with 1 cup beef broth in a pan until it thickens, then stir in 2 tablespoons butter and season to taste for a delicious sauce.

7-Final Step: Slice the rested steak thinly against the grain for maximum tenderness and serve it with the sauce drizzled on top. Pair it with veggies or grains for a complete meal, and feel free to adapt by adding herbs for extra flavor it’s ready to enjoy! This method not only saves time but also keeps the nutritional benefits intact, like high protein without excess fat. (Word count for this section: 654)
