Turn the oven off and use it as a warm, draft-free box for proving dough: switch on just the interior light, or set a tray of just-boiled water on the bottom for gentle warmth and humidity, aiming for around 24–27°C. Never prove in a heated oven — much above 40°C kills the yeast — and keep the dough covered so it doesn't dry out.
Recommended Oven OFF with the light on, or a tray of hot water inside for ~24–27°C — never a hot oven, keep dough covered — Dough rises best somewhere warm, humid and out of drafts, and a switched-off oven makes an ideal enclosed proving box. The safe, simple method is to turn the oven off completely and just switch on the interior light, whose gentle heat brings the closed oven to a cosy 24–27°C — perfect for proving. For a little more warmth and the humidity that stops a skin forming, place a roasting tray of just-boiled water on the oven floor and put the covered dough on a rack above it; refresh the water if you're proving a long time. Many modern ovens have a dedicated 'proof' or 'bread proof' setting that holds a low temperature (around 27–35°C) for you. The rule that matters most: do not proof in an oven that's actually heating or preheating. Yeast slows above about 38°C and dies around 50–60°C, so a warm-feeling oven can kill the rise or set the crust; if you've had the oven on, let it cool to just barely warm first. Keep the dough loosely covered with a damp cloth, oiled wrap or a lid, and judge it by how much it has risen (roughly doubled, or springing back slowly when poked) rather than strictly by the clock.
