Step-by-Step Guide to Baking Irresistible Caramelized Onion Sourdough
Baking sourdough is a journey, not a race. Follow these steps carefully, and you'll be rewarded with a delicious, fragrant loaf.
Preparing Your Caramelized Onions
This foundational step is where much of the bread's incredible flavor begins.
- Step 1: Heat 1-2 tablespoons of olive oil in a large pan or Dutch oven over medium-low heat. Add your thinly sliced onions.
- Step 2: Cook the onions slowly, stirring occasionally, for 25-40 minutes until they are deeply golden brown, soft, and sweet. Avoid high heat to prevent burning. Once caramelized, remove from heat and let them cool completely.
Crafting Your Sourdough Dough
Now, let's get the main dough ready for its flavorful additions.
- Step 3: In a large mixing bowl, combine your active sourdough starter, flour, water, and salt. Mix with a sturdy spoon or by hand until a shaggy dough forms and no dry streaks of flour remain.
- Step 4: Cover the bowl with a damp cloth or plastic wrap and let it rest for 30 minutes (autolyse). This allows the flour to fully hydrate.
- Step 5: After resting, gently knead the dough for 5-10 minutes on a lightly floured surface until it becomes smooth and elastic.
Bulk Fermentation & Inclusions
This is where the magic really happens, as the dough develops flavor and rises.
- Step 6: Transfer the kneaded dough to a lightly oiled bowl. Perform a series of "stretch and folds" every 30-45 minutes for the first 2-3 hours of bulk fermentation. This builds strength.
- Step 7: During the second or third set of stretch and folds, gently incorporate the cooled caramelized onions and grated Asiago cheese into the dough. Distribute them as evenly as possible without deflating the dough too much.
- Step 8: Continue bulk fermenting at room temperature until the dough has nearly doubled in size, feels airy, and passes the "jiggle test." This can take 4-8 hours depending on your starter's activity and room temperature.
Shaping, Proofing & Baking
The final steps before you can enjoy your homemade masterpiece.
- Step 9: Gently turn the dough out onto a lightly floured surface. Shape it into a round or oval loaf (banneton preferred for proofing).
- Step 10: Place the shaped dough into a floured banneton (seam-side up) or a bowl lined with a floured kitchen towel. Cover and refrigerate for 8-16 hours for the final proof. This develops flavor and makes the dough easier to handle.
- Step 11: Preheat your oven to 450°F (230°C) with a Dutch oven inside for at least 30 minutes.
- Step 12: Carefully remove the hot Dutch oven. Invert the cold dough into the Dutch oven, score the top with a sharp blade, and cover with the lid.
- Step 13: Bake for 30 minutes with the lid on, then remove the lid and bake for another 15-25 minutes, or until the crust is deeply golden brown and the internal temperature reaches 200-210°F (93-99°C).
- Step 14: Carefully transfer the baked loaf to a wire rack to cool completely for at least 1-2 hours before slicing. This is crucial for texture and flavor development.
Tips for Sourdough Success
- Active Starter is Key: Ensure your sourdough starter is fed and very active (bubbly and nearly doubled) before you begin mixing the dough.
- Don't Rush Caramelization: This step takes time, but it's where the magic happens. Low and slow is the way to go for truly sweet, flavorful onions.
- Gentle Handling: Sourdough dough is delicate. Handle it gently during stretch and folds and when incorporating inclusions to preserve its airy structure.
- Embrace the Cold Proof: A long, cold proof in the refrigerator significantly enhances the flavor and makes the dough easier to score.
- Listen to Your Dough: Times are estimates. Pay attention to how your dough feels and looks. It's ready when it's light, airy, and has nearly doubled.
Serving Suggestions for Your Caramelized Onion Sourdough

FAQs
How do I know if my sourdough starter is active enough?
An active sourdough starter should be bubbly and float when a small spoonful is dropped into water. It should also have a pleasant, slightly tangy aroma and typically doubles in size a few hours after feeding.
Can I use other types of cheese in this caramelized onion sourdough?
Absolutely! While Asiago adds a wonderful nutty tang, you can experiment with other hard, flavorful cheeses like Gruyu00e8re, Parmesan, or even a sharp cheddar for a different flavor profile.
What is the best way to caramelize onions for this bread?
The key to perfectly caramelized onions is low heat and patience. Cook sliced onions slowly in olive oil, stirring occasionally, for 25-40 minutes until they are deeply golden brown and very soft. Don't rush the process, as this develops their rich sweetness.
How should I store leftover Caramelized Onion Sourdough bread?
To maintain freshness, store the bread at room temperature in an airtight container or a bread bag for 2-3 days. For longer storage, slice the loaf and freeze individual slices, wrapped tightly, for up to 3 months. Thaw and toast as needed.

Description
This irresistible sourdough bread features sweet, deeply flavorful caramelized onions and savory Asiago cheese baked into a wonderfully tangy loaf.
Ingredients
1 cup active sourdough starter
3.5 cups (420g) all-purpose flour
2 teaspoons salt
1.5 cups (360ml) warm water
2 large sweet onions, thinly sliced
2 tablespoons olive oil
1 cup (115g) grated Asiago cheese
Instructions
Step 1: Prepare the Caramelized Onions: Heat 2 tablespoons of olive oil in a large pan over medium-low heat. Add sliced onions and cook, stirring occasionally, for 25-40 minutes until deeply golden brown and very soft. Set aside to cool completely.
Step 2: Mix the Dough: In a large mixing bowl, combine your active sourdough starter, all-purpose flour, warm water, and salt. Stir until a shaggy dough forms and no dry spots remain.
Step 3: Autolyse: Cover the bowl with a damp cloth or plastic wrap and let the dough rest for 30 minutes to allow the flour to fully hydrate.
Step 4: Knead the Dough: Turn the dough out onto a lightly floured surface and knead for 5-10 minutes until it becomes smooth and elastic.
Step 5: Bulk Fermentation & Inclusions: Place the kneaded dough in a lightly oiled bowl. Perform a series of 'stretch and folds' every 30-45 minutes for the first 2-3 hours of bulk fermentation.
Step 6: Incorporate Onions and Cheese: During the second or third set of stretch and folds, gently fold in the cooled caramelized onions and grated Asiago cheese, distributing them evenly throughout the dough.
Step 7: Continue Bulk Fermentation: Allow the dough to bulk ferment at room temperature for a total of 4-8 hours, or until it has nearly doubled in size and feels airy.
Step 8: Shape the Dough: Gently turn the dough onto a lightly floured surface. Shape it into a round or oval loaf. Place it seam-side up in a well-floured banneton or a bowl lined with a floured kitchen towel.
Step 9: Cold Proof: Cover the banneton and refrigerate for 8-16 hours for the final cold proof. This develops flavor and makes the dough easier to handle and score.
Step 10: Preheat Oven: When ready to bake, preheat your oven to 450°F (230°C) with a Dutch oven inside for at least 30 minutes.
Step 11: Bake the Bread: Carefully remove the hot Dutch oven. Invert the dough into the Dutch oven, score the top with a sharp blade, and cover with the lid. Bake for 30 minutes.
Step 12: Finish Baking: Remove the lid and continue baking for another 15-25 minutes, or until the crust is deeply golden brown and the internal temperature is 200-210°F (93-99°C).
Step 13: Cool: Carefully transfer the baked loaf to a wire rack and let it cool completely for at least 1-2 hours before slicing. This is essential for the bread's texture and flavor.
Notes
For best results, ensure your sourdough starter is active and bubbly before beginning. Adjust the amount of Asiago cheese to your liking, or try other hard cheeses like Gruyère or Parmesan. The longer the onions caramelize at a low temperature, the sweeter and deeper their flavor will be.
