205°C is 401°F, Gas Mark 6–7, and 185°C fan/convection. Classified as a Very Hot Oven — the first temperature past the 400°F threshold, and the practical upper limit for most home ovens when baking pizza. This is the temperature for crusty baguettes, pork crackling, roast duck, and anything requiring intense surface heat. 401°F sits between the US standards of400°F (204°C) and 425°F (218°C).

💡 Fan/convection oven: set to 185°C — excellent for crackling and duck as circulating air dries the skin faster. Fan-assisted: 195°C. Gas Mark 6–7: no half-mark on most ovens — use Gas 7 and check early, or Gas 6 with extra time.
205°C is aggressive surface heat — the Maillard reaction operates at full speed, caramelisation is rapid, and moisture evaporates from surfaces almost immediately. This is the temperature where bread takes on a true artisan crust, pork skin transforms into crackling, and duck fat renders properly. It is also the practical maximum for home oven pizza — professional wood ovens operate at 400–500°C, but 205°C with a preheated stone gets close to the result.
RECIPE TIMING GUIDE AT 205°C
Crusty baguettes
22–28 min
Steam first 8 min, then dry heat. Score deeply at 45° before loading.
Pork belly (crackling phase)
25–30 min
After slow cook. Skin dry, salt-rubbed. Intense heat blisters the skin.
Roast duck (whole, 2kg)
90–100 min
Start at 220°C for 15 min, reduce to 205°C. Prick skin all over before.
Thin-crust pizza (home oven)
10–14 min
Preheat stone or steel 45 min. 205°C is the practical home oven max.
Roast potatoes (par-boiled)
40–50 min
Extremely crispy at 205°C. Hot fat, well-fluffed edges, turn halfway.
Whole sea bass (500g)
18–22 min
Scored skin, stuffed cavity. Internal 60°C. Rest 5 min before serving.
Sausage rolls (puff pastry)
18–22 min
Puff deep amber, filling cooked through. Egg wash before baking.
Ciabatta rolls
18–22 min
Very crusty, open holey interior. Steam first 10 min, then vent oven.
Roasted whole peppers
35–40 min
Charred skin, sweet flesh. Rest in sealed bag to steam, then peel.
Focaccia (thick, olive oil)
22–28 min
Golden caramelised top, dimpled. Olive oil pools turn amber at edges.
Times approximate. Watch closely at 205°C — things colour fast. Use a probe thermometer for meat.
205°C
Conventional (fan off)
Standard setting. Very hot — a step above the 200°C bread threshold. Used for baguettes, crackling, and duck where aggressive surface heat is needed.
185°C
Fan / Convection
Reduce by 20°C. 185°C fan is excellent for duck and pork crackling — the circulating air dries the surface faster, improving crispness.
195°C
Fan-assisted (partial fan)
Reduce by 10°C. Good for roast potatoes and crusty bread — more even than conventional, similar heat intensity.
Gas 6–7
Gas Mark
Between Gas 6 (200°C) and Gas 7 (220°C). Most gas ovens do not have a half-mark — set to Gas 7 and check earlier, or Gas 6 and allow a few extra minutes.
Roasting oven (upper-middle)
AGA / Rayburn
Upper-middle shelf of the roasting oven. Approaching the intense heat of the top shelf — good for baguettes and crackling.

Oven accurate
Fix: Use 205°C as written
At 205°C, oven accuracy is critical — a 15°C hot oven burns bread and crackling quickly. An oven thermometer (£5–10 / $8–15) is essential. Preheat for 20 minutes and verify before loading anything.
