Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer at 350°F for 2–3 minutes to restore texture — avoid the microwave, which will make the steak tough. Cut selection: Ribeye works beautifully for a richer result. Avoid tough cuts like flank or skirt steak for this method. Doneness guide: 130–135°F = medium-rare | 140–145°F = medium | 150°F+ = well done. A quick-read thermometer is strongly recommended. Meal ideas: Serve over arugula salad, cauliflower mash, roasted asparagus, or alongside garlic bread for a heartier meal.
