Roasting

Master the mechanics of dry-heat cooking, from temperature control and fat rendering to the science of resting joints for maximum yield.

Roasting is about dry heat, fat management, and air circulation. Get it right, and you get deep caramelisation and intense flavour; get it wrong, and you end up steaming your prep or drying out expensive cuts. The key is managing moisture. Crowding your roasting trays drops the temperature and traps steam, ruining any chance of a crisp exterior.

In this section, we break down the mechanics of roasting across different setups. You will find professional guides on everything from wood-fire roasting with Tournant to high-heat pan work from Chef Jean-Pierre. We cover the fundamental physics of resting roasted meats to preserve yield, alongside regional techniques like Greek slow-roasted lamb and crispy Thai pork belly.

Whether you are looking to refine your Sunday roast service, master high-yield prime rib, or balance acid and fat in a classic Duck à l'Orange, these resources provide the direct, kitchen-tested methods you need to control your oven or open hearth.

Questions from the pass

Roasting: frequently asked

Why should you roast beef at a low temperature instead of blasting it?

Roasting large joints like rib of beef at 120°C instead of 200°C minimises the temperature gradient between the core and the exterior. This prevents the outer meat from overcooking and squeezing out moisture before the centre reaches its target 54°C. Finish with a ten-minute blast at 230°C for crust colour.

How do you get crackling crispy on pork loin?

Score the skin finely, pour boiling water over it to tighten the collagen, then dry thoroughly in the fridge overnight. Roast at 220°C for the first 20 minutes to puff the skin, then drop to 160°C to render the subcutaneous fat. Rubbing with fine salt and a touch of bicarbonate of soda aids crisping.

How long should you rest a roasted joint of meat?

Rest large joints, such as a 3kg sirloin, for at least 20 to 30 minutes in a warm holding drawer at 55°C. This allows muscle fibres to relax and reabsorb water-binding proteins, reducing carving loss from 15% to under 5%, ensuring juices stay in the meat rather than on the board.

Why do roasted root vegetables go soggy instead of caramelised?

Soggy vegetables occur due to overcrowding, which traps steam. Roast carrots and parsnips in a single layer with a 2cm gap between pieces at 200°C. Toss in fat, using 30ml of oil per kilo, to facilitate heat transfer. This dry-heat environment allows surface sugars to exceed 140°C, triggering the Maillard reaction.

What temperature should you pull a roast lamb leg out of the oven?

Pull a whole leg of lamb out of the oven when the internal probe registers 52°C for medium-rare. Carry-over cooking during the 20-minute resting period will raise the core temperature by 4°C to 6°C, bringing it to a perfect 57°C. Pulling it at the final target temperature results in dry, overcooked meat.
