Soft Potato Sandwich Buns are one of those breads that quietly become a kitchen staple once you try them. They look simple on the outside, but the texture tells a completely different story. Thanks to mashed potatoes in the dough, these buns are tender, moist, and stay soft far longer than regular white buns. They are ideal for burgers, breakfast sandwiches, sliders, or even just toasted with butter.
This guide is written for home bakers who want dependable results and a deeper understanding of the process. Every step is explained clearly, from choosing the right potatoes to shaping and baking. Whether you bake bread occasionally or regularly, this recipe is designed to help you achieve consistent, bakery-quality Soft Potato Sandwich Buns at home.
Why Use Potatoes in Bread Dough
Potatoes have been used in bread baking for generations, and for good reason. When mashed potatoes are added to dough, they introduce moisture and starch without adding heaviness. This creates a softer crumb and improves shelf life.
Potatoes also help the dough retain moisture after baking, which is why Soft Potato Sandwich Buns stay fluffy for days instead of drying out overnight. Unlike milk-heavy doughs, potato-based buns remain tender even after refrigeration or freezing.
Another advantage is flavor. The potato taste is subtle, not overpowering, but it adds a gentle richness that pairs well with both sweet and savory fillings.
Ingredients Breakdown and Their Roles
Understanding each ingredient helps you bake with confidence and make adjustments when needed.
Flour
All-purpose flour is ideal for Soft Potato Sandwich Buns because it provides enough structure without making the buns dense. Bread flour can be used, but it will result in slightly chewier buns.
Potatoes
Plain boiled potatoes are the star ingredient. They should be mashed until smooth with no seasoning added. Russet or Yukon Gold potatoes work best due to their starch content.
Yeast
Instant yeast is recommended for ease and reliability. It provides a steady rise and works well with enriched doughs like this one.
Milk
Milk adds softness and helps create a tender crust. Lukewarm milk is essential for activating the yeast without killing it.
Egg
The egg enriches the dough, adding structure, color, and a soft crumb. It also contributes to the buns’ golden appearance.
Butter
Butter adds richness and improves texture. Softened butter blends more easily into the dough and ensures even distribution.
Sugar and Salt
Sugar feeds the yeast and adds mild sweetness, while salt balances flavor and strengthens the dough structure.
Ingredients List
For the Dough
2½ cups all-purpose flour (sifted)
¾ cup mashed potato (plain, unseasoned)
¼ cup milk (lukewarm)
2 tbsp sugar
1 tsp salt
1½ tsp instant yeast
1 large egg (room temperature)
3 tbsp unsalted butter (softened)
2 tbsp water (as needed)
For Brushing
1 tbsp milk
1 tbsp melted butter
Preparing the Potatoes Correctly
The success of Soft Potato Sandwich Buns depends heavily on how the potatoes are prepared.
Peel and boil the potatoes until they are fork-tender. Drain them thoroughly to remove excess water. Any leftover moisture can throw off the dough’s balance. Mash the potatoes while they are still warm, making sure there are no lumps. Measure the mashed potato after mashing, not before boiling.
Allow the potatoes to cool slightly before mixing them into the dough. They should be warm, not hot.
Step-by-Step Instructions
Activating the Yeast
Combine lukewarm milk and sugar in a mixing bowl. Sprinkle the yeast over the top and stir gently. Let it sit for five to seven minutes until foamy. This step ensures the yeast is active.
Mixing the Dough
Add mashed potatoes, egg, butter, and salt to the yeast mixture. Stir until well combined. Gradually add flour, mixing until a soft dough forms. Add water only if the dough feels dry.
Kneading for the Right Texture
Turn the dough onto a lightly floured surface. Knead for eight to ten minutes until smooth and elastic. The dough should feel soft and slightly tacky but not sticky.
First Rise
Place the dough in a lightly greased bowl and cover it. Let it rise in a warm place for one to one and a half hours until doubled in size.
Shaping the Buns
Punch down the dough gently. Divide it into equal portions and shape each into a smooth ball. Place them on a lined baking tray with space between them.
Second Rise
Cover the buns and let them rise again for thirty to thirty-five minutes until puffy and almost touching.
Baking the Buns
Preheat the oven to 180°C. Brush the tops with milk and bake for eighteen to twenty minutes until lightly golden.
Finishing Touch
Brush the hot buns with melted butter immediately after baking. This keeps the crust soft and flavorful.
Common Mistakes and How to Avoid Them
Dense Buns
Dense buns are often caused by under-kneading or insufficient rising time. Make sure the dough is elastic and has doubled in size during the first rise.
Dry Texture
Overbaking or adding too much flour can dry out the buns. The dough should remain soft before baking.
Uneven Size
Weighing the dough portions helps ensure evenly baked buns.
Variations to Try
Whole Wheat Soft Potato Sandwich Buns
Replace up to 50 percent of the flour with whole wheat flour. Add an extra tablespoon of milk to maintain softness.
Slider Buns
Divide the dough into smaller portions for mini buns perfect for sliders or party trays.
Seeded Buns
Sprinkle sesame seeds or nigella seeds on top after brushing with milk.
Dairy-Free Version
Replace milk with warm water and butter with plant-based margarine.
Serving Suggestions
Soft Potato Sandwich Buns are extremely versatile. Use them for classic burgers, grilled chicken sandwiches, or fried vegetable patties. They are excellent for breakfast sandwiches with eggs and cheese or simply toasted with butter and jam.
These buns also work well for packed lunches because they remain soft for hours without refrigeration.
Storage and Freezing Tips
Store baked buns in an airtight container at room temperature for up to three days. For longer storage, freeze the buns once fully cooled. Thaw at room temperature or warm briefly in the oven.

Instructions
Prepare the Mashed Potatoes
- Boil peeled potatoes until fork-tender. Drain completely and mash until smooth with no lumps. Measure the required amount and allow it to cool until warm to the touch. Avoid adding salt, butter, or milk at this stage.
Activate the Yeast
- In a mixing bowl, combine lukewarm milk, sugar, and yeast. Stir gently and let it rest for 5–7 minutes until the mixture becomes foamy. This confirms the yeast is active and ready.
Mix the Dough
- Add mashed potatoes, egg, softened butter, and salt to the yeast mixture. Mix until well combined. Gradually add the flour, mixing until a soft dough forms. Add water only if the dough feels dry.
Knead the Dough
- Transfer the dough to a lightly floured surface. Knead for 8–10 minutes until smooth, elastic, and slightly tacky but not sticky. The dough should spring back when gently pressed.
First Rise
- Place the dough in a lightly greased bowl and cover with a clean kitchen towel. Let it rise in a warm place for about 1 to 1½ hours, or until doubled in size.
Shape the Buns
- Punch down the dough gently to release air. Divide into 8 equal portions. Shape each piece into a smooth ball by tucking the edges underneath. Place them on a parchment-lined baking tray, leaving space between each bun.
Second Rise
- Cover the shaped buns loosely and let them rise again for 30–35 minutes until puffy and slightly touching each other.
Bake the Buns
- Preheat the oven to 180°C. Brush the tops gently with milk for a soft crust. Bake for 18–20 minutes until lightly golden on top.
Finish with Butter
- Remove from the oven and immediately brush the hot buns with melted butter. This keeps the crust soft and adds a rich flavor. Allow them to cool on a wire rack before slicing.
Note
These buns stay soft longer because of the mashed potatoes, making them ideal for meal prep.
For extra richness, replace milk with warm water and 1 tbsp milk powder.
Do not overbake; overbaking can dry out the buns.
If the dough feels sticky, resist adding too much flour—lightly oil your hands instead.
