Potato Rosemary Bread

If you love homemade sourdough bread with a soft texture, crisp crust, and plenty of savory flavor, this Sourdough Potato Rosemary Bread is a recipe you’ll want to make again and again. Tender cooked potato adds moisture and softness to the dough, while fresh rosemary gives the loaf a fragrant, earthy flavor that pairs beautifully with the natural tang of sourdough.

This rustic bread is perfect for breakfast, sandwiches, soups, or serving alongside a family dinner. The potato helps create a wonderfully tender crumb that stays soft longer than many traditional crusty breads. Meanwhile, the rosemary adds a fresh herbal aroma that fills your kitchen while the loaf bakes.

Although sourdough bread requires patience, most of the process is hands-off. With an active starter, a few simple ingredients, and enough time for fermentation, you can create a beautiful homemade loaf from scratch.

Why You’ll Love This Sourdough Potato Bread

There are many reasons to add this loaf to your sourdough collection:

• Soft and tender crumb: Potato adds moisture and creates a lovely texture.

• Naturally fermented: Sourdough starter provides natural fermentation.
• Versatile: Enjoy it with breakfast, lunch, dinner, or snacks.
• Great for leftovers: The bread stays soft and makes excellent toast.
• Simple ingredients: Most ingredients are easy to find.

Ingredients

For the Dough

• 100g active sourdough starter
• 350g bread flour
• 100g cooked potato, mashed and cooled
• 240g water, plus more if needed
• 10g salt
• 1 tablespoon olive oil
• 1–2 tablespoons fresh rosemary, finely chopped

Optional Topping

• 1 tablespoon olive oil
• A few small rosemary sprigs
• Flaky sea salt

Choosing the Right Potato

For this recipe, potatoes with a fluffy texture work especially well. Russet potatoes are an excellent option because they become soft and easy to mash.

You can also use Yukon Gold potatoes, which add a slightly buttery flavor and smooth texture.

Avoid adding potatoes while they are hot. Allow the cooked potato to cool completely before mixing it into the dough. Warm potatoes can interfere with fermentation and make the dough more difficult to handle.

How to Make Sourdough Potato Rosemary Bread

Step 1: Prepare the Potato

Cook the potato until completely tender. You can boil, steam, or bake it.

Once cooked, remove the skin and mash the potato until smooth.

Measure approximately 100 grams of mashed potato and allow it to cool completely.

Avoid adding milk, butter, or other ingredients to the mashed potato. Plain cooked potato works best for this recipe.

Step 2: Mix the Dough

In a large mixing bowl, combine the active sourdough starter and water.

Stir until the starter is mostly dissolved.

Add the cooled mashed potato and mix until it is evenly distributed.

Add the bread flour and mix until a rough dough forms.

Cover the bowl and let the dough rest for about 30 minutes.

This resting period allows the flour to absorb the water and makes the dough easier to develop.

Step 3: Add Salt, Olive Oil, and Rosemary

After the initial rest, add the salt, olive oil, and finely chopped rosemary.

Use your hands to gently squeeze and fold the dough until all the ingredients are incorporated.

The dough may feel slightly sticky because of the potato. This is completely normal.

Avoid adding excessive flour. A properly hydrated dough will produce a lighter and softer loaf.

Step 4: Stretch and Fold

During the first two hours of fermentation, perform several sets of stretch-and-folds.

To do this, grab one side of the dough, gently stretch it upward, and fold it over the center.

Rotate the bowl and repeat on the remaining sides.

Perform a set approximately every 30 minutes.

As you continue, the dough should become smoother, stronger, and more elastic.

The rosemary will become evenly distributed throughout the dough during these folds.

Step 5: Bulk Fermentation

Cover the bowl and allow the dough to ferment at room temperature.

Depending on your kitchen temperature and the strength of your sourdough starter, bulk fermentation may take approximately 4–8 hours.

The dough should become noticeably larger and develop bubbles throughout.

Rather than relying only on a specific number of hours, watch the dough for signs of fermentation.

A warmer kitchen will speed up fermentation, while a cooler kitchen will slow it down.

Step 6: Shape the Dough

Once bulk fermentation is complete, lightly flour your work surface.

Gently turn the dough onto the surface.

Try not to completely deflate it because the trapped fermentation gases help create an airy crumb.

Shape the dough into a round or oval loaf by gently folding the edges toward the center.

Turn the dough over and use your hands to create surface tension by gently pulling it toward yourself.

Step 7: Final Proof

Place the shaped dough into a well-floured proofing basket, seam side up.

Cover it with a clean kitchen towel or reusable bread cover.

You can proof the loaf at room temperature for several hours, depending on the dough’s activity.

For deeper flavor and easier scoring, refrigerate the shaped dough overnight.

The cold fermentation allows the sourdough to develop more complex flavor while making the dough firmer and easier to handle.

Step 8: Preheat the Oven

Place a Dutch oven or heavy oven-safe pot inside your oven.

Preheat the oven to 450°F (230°C) for at least 30–45 minutes.

A properly heated Dutch oven helps create steam during the early stage of baking, which encourages the loaf to expand and develop a beautiful crust.

Step 9: Score the Bread

Carefully turn the chilled dough onto a piece of parchment paper.

Use a sharp bread lame or razor blade to make one deep slash across the top.

You can also add a few decorative shallow cuts.

If desired, brush the top lightly with olive oil and sprinkle with flaky sea salt and a little chopped rosemary.

Step 10: Bake

Carefully transfer the dough into the preheated Dutch oven.

Cover with the lid and bake for approximately 25 minutes.

Remove the lid and continue baking for another 20–25 minutes, or until the crust becomes deeply golden brown.

The exact baking time may vary depending on your oven and loaf size.

A fully baked loaf should sound hollow when tapped and feel firm on the outside.

Step 11: Cool Completely

Remove the bread from the Dutch oven and place it on a wire rack.

Allow the loaf to cool completely before slicing.

This is an important step because the interior continues to set as it cools.

Cutting the bread too early can result in a gummy crumb.

Tips for the Best Potato Rosemary Sourdough

Use an active starter: Your starter should be bubbly and strong before beginning.

Cool the potato: Always use completely cooled mashed potato.

Don’t over-flour: Potato adds moisture, so the dough may feel sticky. Resist adding too much flour.

Use fresh rosemary: Fresh rosemary provides a stronger and brighter flavor than dried rosemary.

Watch fermentation: Sourdough timing varies depending on temperature and starter activity.

Preheat the Dutch oven: A hot baking vessel helps create the ideal crust.

Let the bread cool: Give the loaf enough time to cool before slicing.

Delicious Variations

This bread is easy to customize.

For Garlic Potato Rosemary Bread, add finely minced roasted garlic to the dough.

For Cheesy Potato Rosemary Bread, fold shredded Parmesan, cheddar, or Gruyère into the dough during the final stretch-and-fold.

For a Caramelized Onion Version, add cooled caramelized onions before shaping.

You can also add cracked black pepper for extra savory flavor.

A small amount of grated Parmesan sprinkled over the top before baking creates an especially flavorful crust.

How to Serve It

Sourdough Potato Rosemary Bread is incredibly versatile.

Serve thick slices with butter for breakfast, or toast them and top with eggs and avocado.

It also makes wonderful sandwiches. Use it with grilled chicken, turkey, roasted vegetables, or cheese.

For dinner, serve slices alongside tomato soup, creamy vegetable soup, roasted chicken, or pasta.

You can even cube slightly stale slices and turn them into homemade croutons.

Storage Instructions

Once completely cooled, store the bread in a paper bread bag or airtight container at room temperature.

For the best texture, enjoy it within a few days.

If you want to keep it longer, slice the loaf and freeze the individual pieces in freezer-safe bags.

Frozen slices can be toasted directly from the freezer, making it easy to enjoy homemade sourdough whenever you want.

Frequently Asked Questions

Can I use leftover mashed potatoes?

Yes. Plain leftover mashed potatoes can work well as long as they do not contain large amounts of milk, cream, or butter.

Can I use dried rosemary?

Yes, but fresh rosemary provides a stronger aroma and brighter flavor. If using dried rosemary, use a smaller amount because it is more concentrated.

Why is my dough sticky?

Potatoes add moisture to the dough, so some stickiness is expected. Use lightly wet or oiled hands instead of adding large amounts of flour.

Can I make this without a Dutch oven?

Yes. You can bake the loaf on a preheated baking stone or tray and create steam in the oven using a separate heatproof pan of hot water.

Can I add cheese?

Absolutely. Parmesan, cheddar, mozzarella, and Gruyère are all delicious additions.
