How to Cook Steak in a Cast Iron Skillet

The steakhouse method for a cast iron ribeye: temper, pat dry, salt, sear hard, then baste with butter, garlic and thyme — why iron's heat retention builds the crust.

By Stephen V.Last updated How we pick

A cast iron skillet is the closest most home kitchens get to a steakhouse’s flat-top or broiler, and the reason is mass. A heavy iron pan stores a lot of heat, so when a room-temperature steak hits the surface the pan’s temperature barely drops. That steady, high heat is what drives the browning — the Maillard reaction — and builds the dark, crusted exterior a thin or lightweight pan can’t. Stainless and nonstick pans give up their heat the moment the meat lands and end up steaming the steak in its own juices instead of searing it.

Iron also holds a naturally slick, seasoned surface, so the crust releases cleanly instead of tearing. The method below is the standard steakhouse approach scaled to one pan: get the steak dry and the skillet screaming hot, sear hard on both sides, then finish with foaming butter, garlic and thyme. Nothing fancy — the pan does most of the work.

Method

  1. 1

    Temper the steak

    Take the steaks out of the fridge 30 to 45 minutes before cooking and let them come toward room temperature. A cold center forces you to overcook the outside before the middle warms up, so tempering gives you a more even result.

  2. 2

    Dry and season

    Pat both sides completely dry with paper towels; surface moisture is the enemy of a crust. Season generously with kosher salt (and pepper, if you like) on both sides. A few minutes of resting salt is fine, or salt right before the pan.

  3. 3

    Preheat the skillet

    Set the cast iron skillet over medium-high to high heat and preheat it for 4 to 5 minutes, until it is smoking hot. A properly ripping-hot pan is what separates a sear from a simmer. Turn on your exhaust fan and crack a window, because this makes smoke.

  4. 4

    Add the oil

    Add a thin film of high-smoke-point oil and swirl to coat the bottom. It should shimmer and just begin to smoke almost immediately. Butter would burn at this temperature, which is why you sear in oil and save the butter for later.

  5. 5

    Sear the first side

    Lay the steaks into the pan away from you to avoid splatter, and press them flat for full contact. Do not move them. Sear 2 to 3 minutes, until a deep brown crust forms and the steak releases from the pan on its own.

  6. 6

    Flip and sear the second side

    Turn the steaks and sear another 2 to 3 minutes. For thick cuts, sear the fat edge too by holding the steaks on their side with tongs for a minute so the fat renders and browns.

  7. 7

    Butter-baste

    Reduce the heat to medium. Add the butter, smashed garlic and thyme. Tilt the pan and spoon the foaming butter over the steaks continuously for 45 seconds to a minute. This adds flavor and helps cook the top without flipping again.

  8. 8

    Check doneness

    Pull the steaks a few degrees before your target, since they keep cooking as they rest: about 120-125°F for rare to medium-rare, 130-135°F for medium. An instant-read thermometer is the only reliable gauge; time and touch are guesses.

  9. 9

    Rest, then slice

    Move the steaks to a board or warm plate and rest 5 to 10 minutes before cutting. Resting lets the juices redistribute so they stay in the meat instead of running out. Finish with flaky salt and slice against the grain.

Gear that matters.This recipe lives or dies on heat retention, and that’s exactly what a heavy, inexpensive cast iron pan does best. A plain 10.25-inch Lodge holds enough heat to sear two steaks without stalling; see the picks in our best cast iron skillets roundup, or read the full Lodge cast iron skillet review if that’s the one you’re weighing.

Tips.Cook only one or two steaks at a time — crowding the pan drops the temperature and steams the meat. If your steak is thicker than about 1 1/2 inches, sear it hard, then finish it in a 400°F oven for a few minutes rather than pushing the crust too far. Go easy on the pan afterward: while it’s still warm, wipe out the fat, rinse, dry thoroughly and add a thin coat of oil. A buttery sear doesn’t hurt a seasoned pan — it’s just more of the oil that built the seasoning in the first place.

Frequently asked questions

What is the best cut of steak for a cast iron skillet?

Ribeye, New York strip, and top sirloin all sear beautifully. Ribeye has the most marbling, so it stays juicy and forgiving; strip is leaner with a firmer bite. Aim for a steak about 1 to 1 1/2 inches thick — thin steaks overcook before they can build a crust.

How long do you cook steak in cast iron?

For a 1 to 1 1/2-inch steak over high heat, sear about 2 to 3 minutes per side for medium-rare, plus a minute of butter-basting. Thickness and your stove matter more than the clock, so pull the steak by temperature — about 120-125°F for medium-rare — then rest.

Should you use oil or butter to sear steak?

Both, in order. Sear in a neutral oil with a high smoke point (grapeseed, canola, or avocado), because butter's milk solids burn at searing temperatures. Add butter only at the end, off high heat, for basting and flavor.

Do I need to preheat the cast iron before searing?

Yes. A fully preheated pan is the whole point: 4 to 5 minutes over medium-high until it is smoking hot. Cast iron heats slowly and a little unevenly at first, but it holds that heat once it is there, which is why the sear stays strong when the cold steak lands.
