Spit-roasting (à la broche) is the original and purest form of roasting — meat rotating slowly before radiant heat from an open fire, self-basting as its own fat drips, melts, and redistributes across the surface with each revolution. In the classical French kitchen, the rôtisseur's spit was the centrepiece of meat cookery long before the enclosed oven existed. The physics are fundamentally different from oven roasting: radiant heat strikes the surface directly (like sunlight), creating intense Maillard browning at 140-160°C surface temperature, while the constant rotation ensures no single area is overexposed. The dripping fat falls into the drip pan below, where it is collected and used for arrosage (basting) — traditionally ladled back over the meat every 5-10 minutes. The fire management is critical: hardwood (oak, beech, fruitwood) is preferred over charcoal for its longer burn and aromatic smoke. The heat source should be approximately 30-40cm from the meat, producing a surface temperature of 200-220°C measured by an infrared thermometer. A 2kg chicken requires 60-75 minutes at this distance; a 3kg leg of lamb requires 90-120 minutes. The spit must rotate at approximately 4-6 revolutions per minute — too slow and one side overcooks; too fast and the centrifugal force flings fat off the surface. Internal temperatures follow the standard targets: poultry 72°C at the thigh, lamb 55-58°C for rosé, beef 52-55°C for medium-rare. The defining characteristic of spit-roasted meat is the extraordinarily even, deep-mahogany crust produced by the continuous rotation and the incomparable succulence from constant self-basting.
Constant rotation at 4-6 RPM for even heat exposure on all surfaces Radiant heat from hardwood fire, 30-40cm distance Self-basting: the fat drips, melts, and redistributes with each turn Arroser (baste) every 5-10 minutes with the drippings collected in the lèchefrite (drip pan) Balance the meat on the spit — unbalanced loads rotate unevenly, causing one side to overcook
Tie a bundle of fresh thyme and rosemary to a wooden spoon and use it as your basting brush — the herbs infuse the drippings with each stroke For poultry, stuff the cavity with half a lemon, garlic, and herbs before spitting — the aromatics steam inside, flavouring from within A small fire of vine cuttings (sarments de vigne) added in the final 10 minutes gives a Bordelais smokiness prized in Southwestern French cooking
Spit too close to the fire — the surface chars before the interior cooks Unbalanced loading — heavy side hangs lowest, overexposing it to heat Insufficient basting — the crust dries and toughens without regular fat application Using softwood or treated wood — resinous smoke taints the meat with acrid, creosote flavours Not resting after removal from the spit — the juices need 15-20 minutes to redistribute in a large roast
