Overview
Baking time for sourdough ranges widely because crust, crumb and oven steam interact. Typical home-baked sourdough loaves take 35–55 minutes at high initial ovens (230–260°C / 450–500°F) followed by 10–25 minutes at lower temperatures or with the lid off. Final internal temperature and crumb appearance are the most reliable indicators of doneness, not time alone [1][2].

Troubleshooting & Tips
If the crumb is gummy after cooling: likely underbaked or cut too soon; return to a 200°C (390°F) oven for 10–15 minutes and monitor internal temp to reach 96°C+ [1][2]. If the crust is burnt but crumb undercooked: your oven has hot spots or crust developed too quickly — lower initial bake temp, extend covered phase, or use a lid longer [2]. If oven spring is poor but loaf seems baked through: the bake may have been too long at lower temp; aim for a higher covered phase earlier in the bake to set the crust later [1]. Always check internal temp and crumb texture rather than relying solely on time [1][2].
Typical Times
Common oven schedules used by experienced bakers:
- Covered Dutch oven method: preheat to 245–260°C (475–500°F), bake covered 20–30 minutes, remove lid and bake 10–20 minutes until deep golden and internal temp 96–99°C (205–210°F) [1].
- Baking on a stone with steam: 230–250°C (450–485°F) with steam for first 15–25 minutes, then 15–25 minutes dry [1][2].
- Smaller boules (500–700 g): total 35–45 minutes; larger batards (>900 g): 45–60+ minutes depending on oven and hydration [2][1].
Factors Affecting Bake Time
Several variables change exact bake time:
- Hydration — wetter dough takes longer to set and can need extra time to reach target internal temperature [1].
- Loaf size and shape — thicker loaves hold heat and require longer final bake [2].
- Oven accuracy and heat retention — real temperature can differ from dial; use an instant-read thermometer for the oven and loaf checks [1].
- Preheat and vessel — a well-preheated Dutch oven or cloche traps steam and transfers heat faster, shortening overall bake compared with an unbaked stone [1][2].
- Crust preference — longer dry bake increases crust thickness and color but risks a drier crumb [2].
Step By Step Bake
Practical bake schedule for a 750–900 g boule using a Dutch oven:
- Preheat oven with the Dutch oven inside to 250°C (480°F) for at least 45 minutes.
- Score the loaf with a scoring tool and transfer on parchment paper into the hot pot.
- Cover and bake 20–25 minutes at 250°C to maximize oven spring.
- Remove lid, reduce to 230°C, bake 12–20 minutes until crust color is deep brown and internal temp reaches 96–99°C (205–210°F) [1][2].
- Cool fully on a rack for at least 1–2 hours before slicing to finish starch gelatinization [1]. Use an instant-read thermometer for the loaf’s interior — this is the most objective doneness test [1].
Tools And Equipment
Essential tools that influence bake time and results: weigh ingredients on a Digital Kitchen Scale; shape in a Large Mixing Bowl or on the bench, and use a Dough Scraper for handling. Proof on a Banneton Proofing Basket to preserve shape. For steaming and even heat use a Dutch oven or cloche; score with a scoring tool. Measure final loaf temperature with an instant-read thermometer — this is the most reliable doneness indicator [1][2].
