How to Bake a Rustic Rye Sourdough Loaf
A Rich & Earthy Twist on the Classic Loaf
This rustic rye sourdough recipe builds on the classic sourdough method, adding rye flour for a deeper flavour, darker colour, and hearty texture. Rye creates a slightly denser loaf with a rich, earthy taste while still keeping the soft crumb and crispy crust sourdough lovers enjoy. Using your regular sourdough starter and a simple flour adjustment, this recipe is an easy way to explore different grains and add variety to your homemade sourdough baking.
What You'll Need:
● Active sourdough starter – Make sure it's nice and bubbly before you begin.
● High-grade flour – This will give your dough the structure it needs to rise beautifully.
● Rye flour - Gives that delicious rye flavour.
● Filtered water – Filtered water is best as chlorine can inhibit the yeast.
● Salt – Adds flavor and helps to tighten the dough.
● A mixing bowl – Large enough to allow the dough to double in size.
● A Dutch oven is ideal for achieving that perfect crust.
Note: Use the same sourdough starter you use for your regular loaf.
Step-by-Step Guide:
Step 1:
Mix the Dough
In a large bowl, combine:
● 420g of high-grade flour
● 180g of rye flour
● 430g of filtered water
● 50g of your active sourdough starter
● 10g of salt
Mix until there are no dry patches. The dough will feel heavier and stickier than a normal sourdough loaf — this is exactly what you want. Avoid adding extra flour.
Cover and rest for 30 minutes.
Step 2:
Knead and Stretch
Wet your hands and complete a set of stretch and folds.
Repeat every 30 minutes for around 2 hours.
Rye does not stretch as much as white dough because it contains less gluten, so be gentle. The goal is to build some structure, not make it perfectly elastic.
Step 3:
First Rise (Bulk Fermentation)
Cover and leave somewhere warm until risen. Usually:
-
4–6 hours at room temperature
-
faster in a warm spot
Look for:
✔ dough looks puffier
✔ small bubbles appearing
✔ roughly 50–75% larger
Rye dough does not always double like a white loaf.
Step 4:
Shape the Dough
Turn onto a lightly floured bench.
Shape gently into a round.
Rye dough can be sticky, so lightly wet hands can help.
Place seam-side up into your floured proofing basket.
Step 5:
Second Rise (Proofing)
For this step, we recommend using corn flour to prevent sticking. Place the shaped dough seam-side up in a well-floured proofing basket (or a bowl lined with a cloth and corn flour). Cover it loosely and let it rest in the fridge for 8-12 hours. This slow fermentation gives the bread a deeper rye flavor and helps with structure.
Step 6:
Preheat the Oven
Before baking, preheat your oven to its maximum temperature (usually around 230°C or 450°F). If you’re using a Dutch oven, preheat that as well. This ensures that when the dough hits the heat, you get an incredible oven spring.
Step 7:
Bake Your Loaf
Once your oven is preheated, carefully take the dough out of the fridge. Turn it out onto a piece of parchment paper, score the top with a sharp knife or razor blade, and carefully transfer it into your Dutch oven. Cover with the lid and bake for 20 minutes. After 20 minutes, remove the lid and lower the oven temperature to 220°C (430°F). Bake for another 25-30 minutes. To ensure the perfect bake, we use a thermometer to check that the core temperature hits 94°C before removing the loaf from the oven.
Step 8:
Cool and Enjoy
This part matters more with rye! Once baked, remove the loaf from the oven and let it cool on a wire rack for at least two hours before slicing. Rye holds more moisture, and cutting too early can make the inside gummy. This ensures the crumb sets properly. Now you’re ready to enjoy the fruits of your labor—a beautiful, homemade sourdough loaf!
Final Tip:
Sourdough baking can feel intimidating at first, but the more you bake, the more you’ll get a feel for your dough. Every loaf you bake is a learning experience, and no two loaves are exactly alike—that's the beauty of it!
Frequently Asked Questions:
1. Why should I bake my sourdough in a Dutch oven?
A Dutch oven traps steam released from the dough during baking. This helps create a crisp, golden crust while allowing the loaf to expand fully for better oven spring. If you don't have one, you can still bake sourdough using another covered oven-safe dish or by adding steam to your oven.
2. Can I use my normal sourdough starter for rye sourdough?
Yes! You can use the same sourdough starter you use for a classic white sourdough loaf. Rye flour changes the flavour and texture of your bread, but you do not need a special rye starter. For an extra boost of rye flavour, you can feed your starter with rye flour before baking.
3. Why does rye sourdough need more water?
Rye flour absorbs more water than regular white flour because it contains different proteins and fibre. The extra hydration helps create a softer crumb and prevents the loaf from becoming too dry or dense. Rye dough will naturally feel stickier than normal sourdough — avoid adding extra flour.
4. Why does rye sourdough need to cool for longer before slicing?
Rye holds onto more moisture than white flour, meaning the inside of the loaf continues to set after baking. Cutting too early can make the crumb feel sticky or gummy. Allowing the bread to rest properly gives you cleaner slices and a better texture.
5. Why is my rye sourdough denser than my regular loaf?
Rye contains less gluten than wheat flour, so it cannot trap air in the same way as a traditional sourdough loaf. A slightly tighter crumb and heavier texture are normal and part of what gives rye bread its hearty, rustic character.
