Rest it for as long as it cooked.
That's the rule, and it runs every steak, chop, duck breast and fillet on this site. Sear three minutes a side, that's six minutes in the pan, so it rests six.
When you sear in rounds, the rest matches the round you just finished, not the running total. The Chuletón goes three minutes a side, rests six, back in for three a side, rests six again. Never twelve.
Some cuts want longer. When one does, the recipe says so.
Carryover is the reason
Carryover is the term for when the temperature keeps climbing after something is removed from the pan.
The outside of a piece of meat is far hotter than the middle. Take it off the heat and all that stored energy has nowhere to go but inward. The centre keeps rising for minutes after the stove is off.
That's why you pull it below your number instead of at it. How far below is almost entirely a question of thickness:
| What you're cooking | How far it climbs |
|---|---|
| A thin cut, under an inch | 3 to 5 degrees |
| An inch | 5 to 8 degrees |
| An inch and a half or more | 8 to 10 degrees |
| A roast or a whole bird | 10 to 15 degrees |
A hard fast sear pushes it further than a low slow roast, because a steeper difference between the outside and the middle drives more heat inward.
Salmon comes off at 130 and lands at 135. Halibut is lean, so pull it at 125 to 130 and let carryover finish it.
Once you have the word, it goes with you. Carryover is why the chicken you pulled at 165 reads 172 on the board, why a thin cutlet forgives you and a tomahawk doesn't, and why every temperature in every recipe here is a pull temperature and not a finish temperature.
The juice, honestly
You have read that resting lets the juices redistribute. Nothing redistributes. Nothing travels back.
What happens is quieter. The meat cools, the pressure inside it drops, the liquid gets thicker, and less of it runs out when the knife goes in.
And how much less depends entirely on how big the thing is. On a steak it's a small effect. Kenji López-Alt weighed six of them and the unrested ones gave up about six percent more, which comes out under a tenth of a teaspoon a bite. On a roast it's not small at all. Cook’s Illustrated sliced one pork roast straight out of the oven and lost ten tablespoons, then rested an identical one ten minutes and lost four.
So the honest version is this. On a steak you're resting for carryover. On a roast you're resting for both, and the rest is doing real work.
Either way, pour the resting juices back over before you serve. Whatever came out isn't lost unless you leave it on the board.
Rest it on a rack
A plate traps steam under the meat and softens the crust you just spent ten minutes building. A wire rack lets air underneath.
Foil is a decision, not a default. Tenting slows the cooling, which means more carryover, and it holds steam against the surface, which means a softer crust. Worth it on a big roast you're carving in twenty minutes. Not worth it on a steak.
Where the rule stops
It's for proteins. Bread dough, a frittata, banana bread and a Basque cheesecake all rest, and none of them rest for this reason. They rest so the structure can set. Different job, different clock.
A drying rest isn't this rest. Wings sit in baking powder and salt for ten minutes before they fry so the skin dries out. That has nothing to do with temperature.
Braises don't rest. Pot to plate.
Long roasts and smokes carry their own number. Something that cooked for six hours would rest for six hours under this rule, which is obviously wrong. The rule is a stand-in for thickness, and it only holds where the cook time tracks the thickness. Those recipes state their rest and that's the one to follow.
And there's a top end, which is the crust. If you went back to the pan at the end to re-crisp the skin, the last rest is a short one. Two minutes on a duck breast, not ten. A long rest there undoes the thing you just went back for.
Same reasoning on anything sliced thin. Thin-sliced steak dries out fast once it's off the heat, so rest the piece whole, then slice it and serve it. When the best part of the dish is crisp or thin, the rest gets short and you take a little more carryover in exchange.
