Pull a 1 to 1½ inch steak off the heat about 5°F below the doneness you want, and rest it. For medium rare, that means pulling at 125 to 130°F so it finishes at 130 to 135°F. The chart below has every step from rare to well done, with both numbers: the one to pull at, and the one you'll eat.

Two things decide whether you hit it. The first is where the probe sits: the centre of the thickest part, slid in from the side. The second is carryover: a steak keeps cooking after it leaves the pan, by a few degrees for a weeknight steak and more for a thick one. Both are below, along with the one number food safety adds.

The chart: pull temperature and finished temperature

Doneness Pull it at It finishes at
Rare 115-120°F 120-125°F
Medium rare 125-130°F 130-135°F
Medium 130-140°F 135-145°F
Medium well 140-150°F 145-155°F
Well done 150-155°F 155°F and up

What each one looks like cut open:

  • Rare: deep red, cool to warm, soft.
  • Medium rare: red and warm all the way across.
  • Medium: pink, firmer, the juices start to run.
  • Medium well: a thin pink band, mostly grey-brown.
  • Well done: grey-brown through, firm.

The finished ranges are the ones most butchers, steakhouses and thermometer makers publish; they overlap a little at the edges because people disagree about where medium ends. The pull column is our own call for a 1 to 1½ inch steak seared in a hot pan, built on the 3 to 5°F carryover such a steak usually picks up while it rests. Adjust it for thickness, below.

If you cook for people who want different steaks, the pull temperature is the one to write down. Take the rare steak off first, keep the others going, and they'll all land at once.

Where the probe goes in a steak

Slide the probe in from the side, parallel to the board, until the tip sits in the middle of the thickest part. Going in from the top on a steak barely an inch thick puts the tip too close to the hot pan side and reads high, so you pull it early.

Keep the tip away from bone and from a seam of fat; both read differently from the meat around them. On a T-bone or a bone-in ribeye, go into the thick part of the eye, an inch away from the bone.

Take two readings in slightly different spots and trust the lower one. A fast instant-read thermometer makes this a three-second job; a slow one tempts you to leave the steak on the heat while you wait, which is how medium rare turns into medium. If your readings look off, check the thermometer in ice water first: it should read 32°F.

Carryover: why you pull it early

A seared steak is hotter on the outside than in the middle when it comes off the heat, and that heat keeps moving inward while it rests. The centre goes on rising for a few minutes, then levels off.

How far it climbs depends mostly on thickness and on how hot you cooked it:

  • Under ¾ inch: barely 1 to 2°F. Thin steaks also overshoot in seconds, so pull them at the finished number, not before.
  • 1 to 1½ inches, hard sear: about 3 to 5°F. This is the chart above.
  • 2 inches and up, or a roast: 5 to 10°F, more for a big roast cooked hot.
  • Reverse seared (low oven, then a quick sear): very little, because the outside and the centre are already close. Pull within 2 to 3°F of the finish.

Rest the steak 5 minutes on a board or a rack. Longer doesn't hurt, but it doesn't help the juices either: the point of the rest is the carryover, and that's done in about five.

By thickness: how to get there

Thin steaks (under ¾ inch), like skirt and thin-cut sirloin. Get the pan as hot as it goes, sear a minute or two a side, and check early. By the time a thin steak has a good crust it's usually at medium rare already. Cast iron is the right pan for this: it holds its heat when the cold meat lands, so the crust forms before the middle overcooks. We go through why in cast iron, stainless or nonstick.

Weeknight steaks (1 to 1½ inches), like strip, ribeye and sirloin. Pat dry, salt, sear in a hot pan and flip every minute or so for an even inside. Start checking a couple of minutes before you expect it to be done, and pull at the chart's number. The full method, including the pan sauce after, is in how to sear a steak in a cast iron pan.

Thick steaks (2 inches), like a big ribeye or a porterhouse. Reverse sear: a 250°F oven until the centre is about 15°F under the finish you want, then a minute a side in a very hot pan. A leave-in probe thermometer does the oven part for you: set the alarm, close the door, and it beeps when the steak gets there.

Which doneness for which cut

There's no wrong answer at your own table, but the cuts do behave differently:

  • Ribeye has a lot of internal fat. At medium rare the fat is still firm; at medium rare to medium (about 135°F) it softens and the steak tastes richer. Many cooks take ribeye a few degrees further than strip for that reason.
  • Strip and sirloin are leaner and firm up fast past medium. Medium rare is where they're at their best.
  • Tenderloin (filet) has almost no fat, and it dries out quickly. Rare to medium rare.
  • Flank and skirt are long-grained. Medium rare, then slice thinly across the grain; past medium they turn chewy however you slice them.

The food safety number

The USDA's Food Safety and Inspection Service puts the safe minimum for whole cuts of beef, pork, veal and lamb at 145°F with a 3 minute rest (FSIS safe temperature chart). On the chart above, that's medium well. Rare, medium rare and medium all sit below it, and anyone who's pregnant, very young, older or has a weakened immune system should keep to the 145°F line.

Two kinds of beef don't get the steakhouse exception at all. Ground beef is 160°F, because grinding spreads whatever was on the surface all the way through. And mechanically tenderized steaks, pierced with blades or needles to soften them, carry the surface inside the same way; FSIS requires them to be labelled as such and recommends cooking them to 145°F with the rest. If the label says "mechanically tenderized" or "blade tenderized", treat it like that.

Our safe internal temperature chart has the full list, from chicken to fish.

What we use for this

A steak is the one dinner where a fast thermometer changes the result: the difference between medium rare and medium is a minute in a hot pan. The ThermoWorks ThermoPop 2 is the one we'd buy first; the Thermapen ONE is faster and worth it if you cook meat most nights. We compare the two in ThermoPop 2 vs Thermapen ONE. For the pan, a heavy 12 inch cast iron skillet does the searing.

Questions people ask

Pull a 1 to 1½ inch steak at 125 to 130°F and rest it 5 minutes; it finishes at 130 to 135°F. Pull a thin steak (under ¾ inch) at the finished number, since it barely carries over.

Medium finishes at about 135 to 145°F: pink through the centre and noticeably firmer than medium rare. Pull a weeknight-thick steak at 130 to 140°F.

Yes. The heat at the surface keeps moving inward, so the centre rises about 3 to 5°F on a 1 to 1½ inch steak seared hot, less on a thin one and more on a thick one. That rise is why the chart has a pull column.

The USDA safe minimum for whole beef steaks is 145°F with a 3 minute rest, which is medium well. Medium rare is below it. On an intact whole steak the risk is mostly on the surface, which the sear reaches, but the USDA line is the one to keep for anyone pregnant, very young, older or with a weakened immune system, and for ground or mechanically tenderized beef in all cases.

Not reliably. How firm a steak feels depends on the cut, its fat and its thickness as much as on its temperature. An instant-read thermometer takes three seconds and gives you a number.

About 5 minutes for a weeknight steak. That covers the carryover; resting longer does no harm but doesn’t make it juicier.
