Roast beef
Not a dish to make without a thermometer. The answer to "how many minutes" depends on the temperature at the centre, not on the weight.

Rosto reached Turkish kitchens from the Italian arrosto and settled onto feast-day tables. The whole thing is two temperatures: the surface passing 140 °C for the crust, and the centre staying at 55–60 °C for tenderness. One oven cannot do both at once, which is why the order is reversed — the centre first at a low heat, the crust afterwards at a high one.
Method
- Take the meat out an hour ahead and salt it: the salt works in and dries the surface in that time.
- Heat the oven to 120 °C.
You will need: A meat thermometer · A tray with a rack · A cast-iron pan
-
Rub the meat with the salt, pepper and thyme and crush the garlic over it. Set it on a rack with the carrot and onion underneath.
Look for The surface should be dry and the salt crystals dissolved into it.
Why The rack lets air pass underneath; sitting directly on the tray the base stews in its own juice and the crust forms only on top.Starch still asleep The granules are just floating there doing nothing. No body arrives before 62 °C.
Salt · 1.44% Right in the window. Flavours sharpen, bitterness retreats, water is held.
-
Cook at 120 °C until the centre reads 52 °C — roughly seventy-five to ninety minutes for 1.2 kg. WATCH THE THERMOMETER, not the clock.
Look for The probe should read 52 °C in the thickest part, touching neither bone nor tray.
Why A low oven shrinks the difference between the outside and the centre: at 200 °C, by the time the middle reads 55 the outer layer is at 75 and dry. At 120 the gap narrows to a few degrees and the meat cooks evenly right through.If it went wrong
Past 60 °C it is medium and past 65 it is well done. There is no way back, but the dish is not ruined: slice it very thin and serve it with sauce.
Starch gelatinised The granules soaked up water, swelled and burst into a network. It has thickened, and it will firm further as it cools. no way back

If you want a crust, do not stay under 140 °C. Food cooks at this heat but never colours.
-
Take the meat out, heat the cast-iron pan until it smokes, and sear every side for forty-five seconds in the butter and oil.
Look for Every face should be deep brown and crisp; if the pan is not smoking it is not hot enough.
Why The crust comes last because Maillard takes seconds above 140 °C and barely warms the centre while it happens. The classic order — sear then roast — heats the middle too far.Starch gelatinised The granules soaked up water, swelled and burst into a network. It has thickened, and it will firm further as it cools. no way back
Maillard is running Amino acids have met reducing sugars. The crust, the roasted flavour and that smell all come from here. no way back
Frying dynamics Surface water is flashing to steam and pushing outward — that is the shield keeping the oil out. no way back

-
Rest the meat twenty minutes, uncovered. Then slice it as thin as you can, across the grain.
Look for Very little juice should collect on the board. A puddle means the rest was too short.
Why As it rests the fibres relax and the water pushed outwards redistributes; cut at once, the meat leaves its juice on the board. Covering it with foil steams the crust soft and undoes twenty minutes of work.If it went wrong
If you skipped the rest, lay the slices on a plate and pour the escaped juice back over them: it recovers part of the loss.

What can go wrong here
The meat came out dry and tough⌄
What happened
The meat passed 70 °C. Past that point the muscle fibres contract and wring out their water, while collagen never gets the time to turn into gelatine. It loses moisture and never tenderises.
By the numbers
Beef medium at 57 °C, chicken at 74 °C. Rest it for 10 minutes off the heat; unrested meat leaves its juice on the plate.
Without a thermometer
The palm test: touch thumb to index finger and press the pad below your thumb — that firmness is rare. Middle finger is medium, ring finger is well done. Watch the juice too: pinkish and clear means you are there, running white means you went too far.
After the heat goes off
Thinly sliced, warm or at room temperature. The vegetables from the tray are mashed into a sauce.
Four days in the fridge, unsliced. Sliced meat dries faster: keep it whole.
Do not reheat it. Rosto is meant to be eaten cold or at room temperature; reheated it passes 60 °C a second time and dries.
Three months, unsliced. Thaw it slowly in the fridge: thawed at room temperature it loses water.
Thin slices make the best sandwich there is; the ends go into a salad or pasta.
Meat cooked to 52 °C at the centre does not suit a baby under one or a 12–36 month old: with a whole cut the risk is on the surface and the surface was seared, but a toddler’s slice is better cooked through. For a school-age child it is fine.
- Red meat → Turkey meat (skinless) Turkey breast takes the same technique but wants a centre of 68 °C: the safe threshold for poultry is different.
