What You’ll Need for This Easy Flat Iron Steak Recipe
Flat iron steak – Known for its tenderness and rich marbling, this cut cooks quickly while staying juicy and flavorful.
Seasoned salt – Adds a savory base with a hint of umami, enhancing the natural beefy flavor.
Italian seasoning – A balanced herb mix that brings subtle earthiness and aromatic depth.
Black pepper – Provides a mild heat and sharpness that brightens the seasoning blend.
Garlic powder – Adds a warm, nutty depth without overpowering the steak.

Unsalted butter – Used for searing, it gives the steak a golden crust and rich finish without adding extra salt.
Cooking the Easy Flat Iron Steak Recipe to Perfection
This steak comes together quickly in one pan with just a handful of steps. First, mix the seasonings and rub them generously over the steak. Then, sear in a hot skillet with butter for a deeply caramelized crust and tender, juicy interior. Rest before slicing to seal in the flavor.
Tips for the Best Easy Flat Iron Steak Recipe
For an even sear, let the steak sit at room temperature for about 15 minutes before cooking. If using a different cut, such as skirt or flank steak, adjust cooking times as these are thinner. A meat thermometer helps—130°F for medium-rare, 140°F for medium.
Storing Leftovers from the Easy Flat Iron Steak Recipe
Leftover steak should be cooled and stored in an airtight container in the refrigerator for up to 3 days. To reheat, use a skillet over low heat or slice and enjoy cold in salads or wraps. Avoid microwaving, as it may dry out the steak.
Frequently Asked Questions
Can I grill the flat iron steak instead of pan-searing it?
Yes, grilling works well. Preheat the grill to high, sear each side for 4–5 minutes, and check doneness with a thermometer.
What sides pair well with flat iron steak?
Try roasted vegetables, garlic mashed potatoes, or a fresh green salad for a balanced meal.
Can I marinate the steak beforehand?
You can, though the dry seasoning mix already adds great flavor. A simple olive oil and vinegar marinade works if you prefer.

Always slice against the grain to maximize tenderness and make each bite more enjoyable.
