To cook Cast-Iron Steak, pat the meat dry and place it in a thoroughly preheated, lightly oiled cast-iron pan. Sear both sides, finish to your preferred doneness, then let the steak rest before slicing.
Yes, preheat the pan before cooking Cast-Iron Steak. Cast iron takes time to heat evenly, and a properly hot surface helps brown the meat rather than letting it stew in its own juices.
Flip Cast-Iron Steak when the first side has developed a browned crust; you can also turn it repeatedly for more even cooking. Avoid pressing the steak down, since that squeezes out juices without improving the sear.
Cast-Iron Steak can smoke because the pan is very hot or the cooking fat has a low smoke point. Use a well-ventilated kitchen, remove excess oil, and choose a fat that tolerates high heat.
Yes, you can cook Cast-Iron Steak from frozen, but the center takes longer to heat than the outside. Sear it first, then finish it more gently and use a meat thermometer to check doneness.
No, keep the pan uncovered while searing Cast-Iron Steak. A lid traps steam and softens the browned crust; cover it only if you are deliberately finishing a thick steak more gently after searing.
A thicker steak is easier to sear on the outside while keeping the center less cooked, which suits Cast-Iron Steak particularly well. Very thin cuts cook quickly, so watch them closely to avoid overcooking.
Yes, you can finish Cast-Iron Steak in the oven after searing, especially when the cut is thick. Use an oven-safe pan and check the center with a meat thermometer rather than relying only on the exterior color.
Let Cast-Iron Steak rest briefly on a plate or board before cutting. Resting gives the juices time to settle, so less liquid runs onto the plate when you slice the meat.
Clean the pan after making Cast-Iron Steak while it is still warm, not scorching hot. Loosen stuck-on bits with hot water and a brush or scraper, dry it thoroughly, and apply a thin layer of oil if needed.

Cast-Iron Steak is a steak cooked in cast-iron cookware, usually seared over high heat. It is a cooking style rather than a dish tied to one particular place: the heavy pan holds heat well and helps form a browned crust while the centre cooks to your liking. Let the steak rest before slicing so its juices settle. It works as a straightforward main with potatoes, a green salad or seasonal vegetables, whether served at home or in a steakhouse-style meal. It is protein-rich, with 25.5 g of protein per 100 g, and provides iron and vitamin B12. For a lighter plate, use only a little added fat and serve it with plenty of vegetables.
