Instructions

1. Tenderize the steak: Use the textured side of a meat mallet to pound both sides of the steak once or twice, leaving light marks.
2. Season the meat: Place the steak in a baking dish. Sprinkle with salt and black pepper, pressing it gently into the surface.
3. Marinate: In a small bowl, combine all marinade ingredients. Pour over the steak, flip to coat both sides, cover with plastic wrap, and refrigerate for at least 8 hours or overnight. Flip once during marinating if possible.
4. Bring to room temperature: Remove steak from the fridge and let it sit, covered, at room temperature for 30–45 minutes before cooking.
5. Preheat air fryer: Set the air fryer to 400°F (200°C) for 5 minutes.
6. Cook the steak: Place the steak carefully in the air fryer basket. Cook at 400°F for 8 minutes, flip, then cook an additional 6–10 minutes depending on thickness and starting temperature. The internal temperature should reach 130°F for medium-rare.
7. Rest and slice: Transfer the steak to a cutting board and let it rest for 10 minutes. Slice against the grain into ½-inch thick pieces.
8. Optional toppings: Top with Blue Cheese Butter or serve with Blue Cheese Horseradish Sauce on the side.
