Why This Technique?
A hot baking stone or steel gives immediate, intense bottom heat that improves oven spring and produces a thin, crisp crust.
A stone or steel stores thermal energy and transfers it quickly to the dough when placed in the oven, which rapidly expands gases in the crumb and helps set the crust before the loaf cools. This results in better oven spring and more caramelized crusts compared with baking on a cold tray [1]. Using a stone combined with surface steam in the first minutes of baking further delays crust setting and increases volume [1][2].
🛒 Recommended Products
We recommend the following tools for this recipe:
Dutch Oven or Cast Iron Pot (CRUSTLOVE)
Useful alternative to a stone for steam retention and oven spring
Parchment Paper (Katbite)
Easier transfer of shaped dough onto the hot stone and prevents sticking
Oven Mitts (Gorilla Grip)
Essential for safe handling of hot stones and trays
Banneton Proofing Basket (DOYOLLA)
Holds shape for final proof prior to transferring to the stone

When to Use
✓ Suitable for:
- • Final shaped dough that has completed proof and holds shape
- • High-hydration or artisan loaves where oven spring is important
- • Breads where a crisp bottom crust is desired
✗ Not suitable for:
- • Very sticky, under-proofed dough → Dough will stick or flatten on the stone; use a preheated Dutch oven instead
- • Delicate loaves that require a pan → Shallow loaves or enriched doughs may bake better in pans
Step by Step
Preparation:
Place your stone or steel on the middle rack cold and preheat the oven to the target temperature for at least 45–60 minutes so the mass reaches steady-state heat. Use a [digital kitchen scale](https://amzn.to/4pUMVHi) to weigh dough and a [banneton proofing basket](https://amzn.to/4sNHBYO) for final proof if needed.
Score oven plan and tools: preheat oven with the stone/steel in place; place an empty metal tray on the bottom rack to generate steam.
When the loaf is fully proofed, invert it onto a piece of parchment paper or a peel to prepare for transfer. If using a banneton, shake or flip the basket to release the dough.
Open the oven quickly, slide the loaf (with parchment) onto the hot stone or steel using a peel or the parchment as a sling, and immediately pour a cup of hot water into the preheated bottom tray to create steam (or use other steam method).
Close the oven and maintain high heat for the first 12–20 minutes to maximize oven spring, then reduce temperature or remove steam source according to recipe.
For a deep, crisp crust, bake directly on the stone for the full bake. If bottom browning is too strong, lift the loaf off the stone onto a rack for the last 5–10 minutes.

How Often?
Preheat stone/steel at full bake temperature for 45–60 minutes before baking each load.
How do I know it's enough?
Loaf achieves strong initial rise in first 10–15 minutes, bottom is crisp and caramelized but not burnt, and internal temperature reaches ~98–99°C (208–210°F) for fully baked sourdough [1][2]. Use an [instant-read thermometer](https://amzn.to/49Xsgwp) for confirmation.
Common Mistakes
❌ Insufficient stone preheat
Problem: Stone won't transfer enough heat; oven spring is reduced and bottom may be pale
Solution: Preheat 45–60 minutes and verify oven reaches target temp; if using steel, shorter time may be sufficient but still preheat long enough [1]
❌ Placing dough directly on cold parchment or wet surface
Problem: Dough can stick or lose shape on contact with a cooler surface
Solution: Use lightly floured parchment or a [silicone bread sling](https://amzn.to/4q71MyA) for transfer, and release dough close in time to transfer
❌ No steam or delayed steam
Problem: Crust sets too quickly and restricts oven spring
Solution: Introduce steam immediately when the dough enters the oven (pour hot water into tray or use other steam method) and keep oven door opening brief [2]
❌ Using very wet dough without a sling
Problem: Dough may stick to the stone
Solution: Proof on a well-floured banneton and use parchment to lift the loaf; dust with rice flour if necessary [1][2]
