Roasting over open fire is humanity's oldest cooking technique. The French classical codification of oven roasting — starting high, reducing heat, basting, resting — reflects centuries of empirical refinement. Escoffier's brigade kitchen had a dedicated rôtisseur station, a recognition that managing roasting temperatures and timing with precision was skilled labour, not background work.
Roasting is the application of dry, high oven heat to a protein in a way that simultaneously browns the exterior through Maillard reactions and conducts heat to the interior at a rate that achieves the correct internal temperature at the moment the exterior colour is correct. The two processes — exterior browning and interior cooking — happen at different rates in different ovens on different proteins, and the cook who manages both to completion simultaneously has mastered the technique.
- **The initial blast:** Most proteins benefit from starting at high heat (220–230°C) for the first 15–20 minutes to initiate surface browning, then reducing heat (170–180°C) for the remaining cooking time. The reverse — starting low and finishing high — is used for larger cuts where the low temperature ensures even interior cooking. - **Resting is not optional.** The juices that have been pushed toward the centre of the meat by the heat of the oven are redistributed throughout the flesh during rest. Cut before resting and those juices run out onto the board. For a chicken: rest 10 minutes. For a leg of lamb: rest 20 minutes. For a rib roast: rest 30 minutes. - **Basting:** The natural juices and fat that render into the roasting pan should be used to baste the protein at intervals. Basting does not speed cooking; it maintains moisture at the surface and adds a repeated layer of rendered fat and aromatic compounds to the exterior. - **The thermometer:** An instant-read thermometer removes all guesswork. Chicken thigh: 74°C. Beef medium-rare: 52°C (before rest). Lamb medium: 58°C (before rest). Pork: 63°C minimum. The thermometer is faster, more accurate, and more honest than any finger or skewer test. Decisive moment: Pulling the protein from the oven 5°C below the target temperature. Carryover cooking — the heat stored in the protein's exterior continuing to cook the interior after the oven heat is removed — raises the internal temperature by 3–8°C during rest depending on the size and density of the piece. A chicken breast pulled at 68°C will reach 73°C during the rest. A rib roast pulled at 49°C will reach 54°C. Plan for carryover; it is not an accident. Sensory tests: **Sound:** A correctly roasting bird should be producing a steady, moderate sizzle and crackle from the roasting pan. A very loud, aggressive sound means the oven is too hot. Silence means the oven is too cool and the surface is not browning. **Sight:** The skin of a well-roasted chicken at the correct temperature is golden-brown and tight, not pale and flabby. The juices running from the thigh joint, when pierced, should run clear with no pink. **Feel — the press test:** Press the thickest part of the breast with a finger through a cloth. It should spring back decisively — moderate resistance, complete rebound. A breast that yields softly is undercooked; a breast that feels rigid and firm is overcooked.
- Always put the bird or roast on a rack — direct contact between protein and roasting pan steams the bottom surface and produces uneven browning. - The fond in the roasting pan is the foundation of the best pan sauce you will ever make. Deglaze with wine and stock while the pan is hot; reduce; mount with butter.
— **Pale exterior, raw interior:** Oven not preheated, or temperature too low throughout. Add 10 minutes more time at 200°C before checking again. — **Browned exterior, raw interior:** Oven too hot. The exterior Maillard reaction completed before the heat had time to conduct to the centre. Cover loosely with foil and reduce temperature. — **Dry, stringy meat:** Overcooked. No recovery — but correct this for next time by pulling at a lower internal temperature and trusting carryover.
