Mastering Oven Spring
Oven spring is the final, rapid expansion of dough that happens in the first few minutes of baking. It occurs when yeast and gases trapped within the gluten network expand rapidly due to heat before the crust sets. To achieve this, your dough must have structural integrity, proper fermentation, and be loaded into a sufficiently hot environment with ample steam.
Watch your fermentation
If you over-proof your dough, the yeast will have consumed its energy and the gluten structure will be too weak to support expansion, resulting in a flat loaf.

Directing the expansion
Scoring isn't just for looks; cutting the dough at a 45-degree angle creates a hinge that allows the crust to open up like a flap, preventing the loaf from rupturing in random spots.
The method.
Preheat aggressively
Get your oven and your baking vessel to at least 475°F (245°C) for a full hour before the dough goes in.
Score with purpose
Use a sharp blade to make a deep, confident cut. If you hesitate, the dough will drag and pull, collapsing the bubbles you spent hours developing.
Introduce steam
Steam keeps the exterior of the dough soft and supple for the first 10 minutes, allowing it to expand fully before the crust hardens.
Remove the lid
After the initial lift, remove the Dutch oven lid or remove the steam source to allow the crust to caramelize and harden.
When it doesn't go to plan.
Cold dough holds its shape better; try putting your shaped loaf in the fridge for 30 minutes before baking to make scoring cleaner.
Don't skip the steam; a dry oven sets the crust prematurely, trapping the loaf in a tight, small shape.
If using a stone, place a tray on the bottom rack and pour half a cup of boiling water into it right as you close the oven door.
The ones that keep coming up.
Why does my bread collapse when I score it?
This usually means it was over-proofed. The gluten has lost its elasticity and cannot hold the gas pressure inside.
Does hydration affect oven spring?
Yes. Higher hydration doughs often produce more dramatic spring because the moisture turns to steam inside the loaf, but they are harder to handle and score.
