How to Bake Perfect Sourdough in a Cast Iron Skillet
Written By James MorganBaking sourdough bread is a cherished kitchen tradition. When you combine it with a cast iron skillet, you create a culinary masterpiece. Whether you're a culinary professional or an enthusiastic home baker, learning how to bake sourdough in a cast iron skillet can elevate your bread game to a whole new level.
Cast iron skillets offer even heating and excellent heat retentionqualities that are crucial for baking the perfect sourdough loaf. In this comprehensive guide, we'll walk you through the step-by-step process, from preparing your dough to achieving that beautiful, crackly crust. Let's dive right in!
Why Use a Cast Iron Skillet for Sourdough?
Even Heat Distribution
One of the foremost reasons to use a cast iron skillet is its ability to distribute heat evenly. Uneven heating can lead to bread that's raw in some parts and overcooked in others. With a cast iron skillet, the dough receives consistent heat, ensuring a uniformly baked loaf.
Excellent Heat Retention
Another advantage is cast iron's remarkable heat retention. Once the skillet has reached the desired temperature, it holds the heat exceptionally well. This ensures that your sourdough starts baking at a high temperature, which is crucial for good oven spring and a beautifully crusty exterior.
Getting Started: Ingredients and Tools
Essential Ingredients
- Flour (preferably bread flour or a mix of bread and whole wheat flour)
- Water (filtered or bottled for better fermentation)
- Salt (preferably sea or kosher salt)
- Natural Sourdough Starter (you can make your own or buy one here)
Needed Tools
- Cast iron skillet (with lid if possible)
- A mixing bowl
- A dough scraper
- A kitchen scale
- Baking parchment paper
- Lame or sharp knife for scoring
- Proofing basket (optional but helpful)
Step-by-Step Guide to Baking Sourdough in a Cast Iron Skillet
Step 1: Feed the Starter
Before you start baking, make sure your sourdough starter is active. Feed it with equal parts flour and water about 6-8 hours before you plan to bake. When it's bubbly and has doubled in size, it's ready to use.
Step 2: Mixing the Dough
Combine the ingredients in a mixing bowl. Typically, use a 1:2:3 ratio (1 part starter, 2 parts water, 3 parts flour). Mix until a shaggy dough forms, then let it rest for about 30 minutes.
Step 3: Autolyse
Allow the dough to rest, or autolyse, for 30 to 60 minutes. This resting period enables the flour to fully hydrate, improving gluten development, which in turn makes the dough easier to shape and handle.
Step 4: Kneading and Folding
Once the autolyse is complete, start the kneading process. This can be done by hand using the slap-and-fold method or with a stand mixer. Alternatively, use a series of stretch-and-folds over a period of 2-3 hours, which gently builds gluten strength without the need for vigorous kneading.
Step 5: Bulk Fermentation
Transfer the dough to a lightly oiled bowl, cover, and let it ferment at room temperature for 3-4 hours, or until it has almost doubled in size. During this time, perform light stretch-and-folds every 30 minutes for the first 2 hours to further develop the dough's structure.
Step 6: Shaping the Dough
After bulk fermentation, gently turn the dough onto a floured surface. Pre-shape the dough into a loose round and let it rest for about 20 minutes. Then, shape the dough into its final formusually a round (boule) or oval (batard). Transfer the shaped dough to a proofing basket lined with a well-floured cloth, seam side up.
Step 7: Final Proofing
Allow the dough to undergo a final proof, either at room temperature for 2-4 hours or in the refrigerator overnight. The overnight option, known as cold retarding, slows fermentation and can enhance the flavor and final texture of the bread.
Step 8: Preheating the Oven and Skillet
Preheat your oven to 475F (245C). Place the cast iron skillet (and its lid, if using one) in the oven while it preheats. The skillet needs to be scorching hot to give your bread the initial burst of heat needed for a good oven spring.

Step 9: Scoring the Dough
Once the dough has fully proofed and the oven is preheated, carefully turn the dough out onto a piece of parchment paper. Using a lame or a sharp knife, score the top of the dough. This allows the bread to expand properly and gives it an attractive appearance.
Step 10: Baking the Bread
Carefully remove the hot cast iron skillet from the oven. Using the parchment paper as a sling, transfer the dough into the skillet. Cover with the lid (if using) and return it to the oven. Bake covered for the first 20 minutes to trap steam, which helps develop a crispy crust. After 20 minutes, remove the lid and continue baking for another 20-25 minutes, or until the crust is deeply golden brown and the internal temperature reaches about 200F (93C).
Step 11: Cooling
Once baked, remove the bread from the skillet and let it cool on a wire rack. Cooling is crucial as it allows the crumb to set. Cutting into hot bread can result in a gummy texture, so patience is key!
Common Challenges and How to Overcome Them
Getting the Right Consistency
Achieving the perfect dough consistency can be challenging for beginners. If your dough feels too sticky, gradually add more flour until it is manageable. Conversely, if it's dry, add a little water. Remember, wetter dough often leads to better open crumb structure, but it can be harder to handle.
Maintaining Starter Health
Your sourdough starter is the heart of your bread. Keeping it healthy requires regular feedings and the right temperature. If your starter isn't rising predictably or developing bubbles, consider adjusting its feeding schedule or the temperature at which it's kept.

Managing Fermentation Time
Fermentation is influenced by many factors, including room temperature, starter activity, and dough hydration. Keep an eye on your dough rather than rigidly following the clock. The dough should appear puffed and lively before proceeding to the next step.
Tips for Enhancing Flavor
Whole Grain Flours
Incorporating whole grain flours such as whole wheat or rye can deepen the flavor profile of your sourdough bread. These flours contain more oils and nutrients, which contribute to a richer taste.
Hydration Levels
Experimenting with higher hydration levels (more water in the dough) can result in a more open crumb and a more complex flavor. However, higher hydration doughs can be tricky to handle, so it's best to gradually increase the water content as you become more comfortable with the dough's behavior.
Cold Fermentation
As mentioned earlier, cold retarding your dough in the refrigerator allows the flavors to develop more fully. The slow fermentation at lower temperatures gives the bacterial and yeast activity time to create a more nuanced taste.
Frequently Asked Questions
How do I know if my sourdough starter is ready to use?
Your starter is ready when it's bubbly, has risen, and has a pleasant tangy aroma. A simple float test can also be performed: drop a spoonful of starter into waterif it floats, it's ready to use.
Can I bake sourdough without a lid for my cast iron skillet?
Yes, you can, but using a lid helps trap steam, which is crucial for crust development. If you don't have a lid, consider placing your skillet in a Dutch oven or creating steam in your oven by placing a tray of water at the bottom. Check out how to burn a cast iron skillet for better results.
Why is my sourdough flavor too mild?
A mild flavor may result from a young starter, short fermentation times, or using only white flour. To boost flavor, try longer fermentation, incorporating whole grains, or cold retarding the dough overnight.
By following these steps and tips, you'll be well on your way to mastering how to bake sourdough in a cast iron skillet. Happy baking!
