Best Pan for Baking Sourdough Bread: Cast Iron, Glass, or Steel?

The best pan for baking sourdough bread is a preheated cast iron Dutch oven. Its heavy, tight-fitting lid traps steam from the dough, creating a crisp crust and helping the loaf spring up. For sandwich-style loaves, a 9×5-inch pullman pan with a lid is ideal for even browning and uniform slices.

Quick Answer

Quick answer: For artisan round loaves, use a cast iron Dutch oven (5-7 quart). For sandwich loaves, use a 9×5-inch pullman pan with lid. Both provide steam control and even heat distribution.

Best for crusty round loaves: Cast iron Dutch oven (5-7 quart) – preheat with lid, then bake covered 20-30 min, uncover for final browning.
Best for sandwich loaves: Pullman pan (9×5 inch with lid) – gives straight walls and soft crust; bake covered entire time.
Best for beginners: Enameled cast iron Dutch oven (e.g., Le Creuset or Lodge) – requires no seasoning and is easy to clean.
Best budget option: Unglazed ceramic cloche or a steel loaf pan with a foil cover – much cheaper but still effective.

Why Dutch Ovens Excel for Sourdough

A Dutch oven is the gold standard for baking sourdough because it mimics a professional steam-injected oven. The preheated pot provides intense, even heat to the dough, while the lid traps the moisture released by the dough during the first 20 minutes of baking. This steam keeps the crust supple, allowing maximum oven spring, then the lid is removed to let the crust dry and crisp.

For best results, preheat your Dutch oven in a 475°F oven for at least 30 minutes. Carefully transfer the proofed dough onto a piece of parchment paper, score it, and lower it into the hot pot. Cover and bake for 20-25 minutes, then remove the lid and bake another 20-25 minutes until deep golden brown. The internal temperature should reach 205-210°F.

Pullman Pans for Sandwich Loaves

If you prefer a soft-sided, uniform loaf for sandwiches, a pullman pan (also called a lidded loaf pan) is the best choice. The lid traps steam, giving the bread a tender crust and keeping the shape perfectly square. The pan is typically 9×5 inches (holds about 2.5 pounds of dough).

To use: grease the pan and lid lightly. Place the proofed dough inside, slide the lid on, and let it rise until the dough reaches just below the lid (about 1 inch from the top). Bake at 375°F for 35-40 minutes. The lid prevents direct heat on the top, so the crust stays soft. For a slightly browner top, remove the lid for the last 5 minutes.

Glass and Ceramic Alternatives

Glass and ceramic baking dishes (like Pyrex or stoneware) can work for sourdough but have drawbacks. They don’t preheat as evenly as cast iron, and glass can’t handle high heat above 450°F without risk of shattering. However, a 3-quart Pyrex bowl with a glass lid can be used similarly to a Dutch oven if you’re careful.

Ceramic cloches, such as the Breadtop, are designed for artisan loaves and provide good steam retention. They are lighter than cast iron and often have a porous surface that absorbs moisture, contributing to a crunchy crust. The downside: they are more fragile and may crack if subjected to sudden temperature changes. Always place them in a cold oven and let them heat up gradually.

Baking Stones and Steel Plates

Baking stones and steel plates are excellent for creating a crisp bottom crust, but they don’t trap steam. To get oven spring with these, you must add steam manually. Place a rimmed baking sheet on the bottom rack and pour 1 cup of hot water into it when you load the dough, then quickly close the oven door.

Alternatively, use a cast iron skillet filled with lava rocks or chains to hold steam longer. Preheat the stone or steel at 500°F for 45 minutes. Slide the dough onto the hot surface using a peel, then add steam. Bake at 475°F for 25 minutes, then reduce to 450°F and bake 15-20 minutes more. Steel conducts heat faster than stone, giving a darker, crunchier bottom crust.

Loaf Pans Without Lids (Standard Metal)

A standard 9×5-inch metal loaf pan without a lid is fine for everyday sourdough sandwich bread, but it won’t give you a soft crust. The exposed top will brown and harden. To compensate, brush the top with butter after baking or wrap the loaf in a clean towel while cooling to soften the crust.

For a taller loaf, use a pan with straight sides (not tapered). Preheat the pan in the oven for 10 minutes before adding the dough to help with oven spring. Bake at 375°F for 30-35 minutes. If the top is browning too fast, tent loosely with foil after 20 minutes. This method is simple but doesn’t rival the results of a Dutch oven or pullman pan.

Pro Tips

Place the Dutch oven on the lowest rack to avoid burning the top crust before the bottom is done.
For a Pullman pan, lightly oil the lid’s underside to prevent sticking; wipe off excess oil before baking.
If using a baking stone, let it preheat for a full 45 minutes to ensure it’s hot enough for good oven spring.
Use a digital thermometer to check doneness: sourdough is fully baked when the internal temperature reaches 205-210°F.

Common Mistakes to Avoid

Adding cold dough to a hot Dutch oven without parchment can cause sticking; always use a sling of parchment paper.
Skipping the preheat on a Pullman pan lid leads to uneven heat distribution and a pale top crust.
Using a glass dish above 450°F risks thermal shock and shattering; keep it at or below 425°F.
Overloading a baking stone with too much steam can cause the dough to collapse; use only 1 cup of water for the steam pan.

FAQ

Can I use a regular loaf pan for sourdough?

Yes, but the crust will be firmer and less uniform. For a softer crust, cover the pan tightly with foil for the first 25 minutes of baking.

Do I need to preheat the pan for sourdough?

Preheating a Dutch oven or baking stone is essential for oven spring. For standard loaf pans, preheating is optional but can help create a better bottom crust.

What size Dutch oven is best for a single loaf?

A 5-7 quart round Dutch oven fits most standard sourdough boules. A 4-quart is too small for a full 1000g loaf; a 7.5-quart is fine but may spread the dough too thin.

The Bottom Line

The best pan for baking sourdough bread depends on your desired style: a cast iron Dutch oven for artisan round loaves with a crisp crust, or a Pullman pan for soft-sided sandwich bread. For budget-friendly options, a ceramic cloche or a regular loaf pan with foil works well. Whichever you choose, preheating and steam management are the keys to a beautiful, delicious loaf.
