Potato bread is a soft, slightly sweet loaf made with mashed potatoes in the dough, giving it a tender crumb and a moist texture that stays fresh longer than regular white bread. It’s a beloved staple in Irish and American baking, often served sliced for sandwiches, toast, or alongside hearty meals. This recipe yields a beautifully sliceable loaf that’s perfect for everyday use.
Ingredients
- 1 cup (240 ml) warm water (110°F / 43°C)
- 2 1/4 teaspoons (7 g) active dry yeast (one packet)
- 1 teaspoon (4 g) granulated sugar
- 1 cup (240 g) mashed potatoes, cooled (from about 2 medium potatoes)
- 1/4 cup (60 g) unsalted butter, melted and cooled
- 1 large egg, at room temperature
- 1 tablespoon (15 ml) honey or sugar
- 1 1/2 teaspoons (9 g) salt
- 3 1/2 cups (455 g) all-purpose flour, plus more for kneading
- 1 tablespoon (15 ml) vegetable oil, for greasing the bowl
Instructions
- In a small bowl, combine the warm water, yeast, and 1 teaspoon sugar. Let sit for 5–10 minutes until frothy. If it doesn’t foam, the yeast is inactive—start over.
- In a large mixing bowl, combine the mashed potatoes, melted butter, egg, honey, and salt. Mix until smooth.
- Add the yeast mixture and stir well. Gradually add the flour, 1 cup (130 g) at a time, mixing until a soft dough forms.
- Turn the dough onto a lightly floured surface. Knead for 8–10 minutes until smooth and elastic, adding flour only as needed to prevent sticking. The dough should be slightly tacky but not sticky.
- Place the dough in a greased bowl, turning to coat. Cover with a clean kitchen towel and let rise in a warm place until doubled, about 1 hour.
- Punch down the dough. On a floured surface, shape it into a loaf and place it in a greased 9×5-inch (23×13 cm) loaf pan.
- Cover loosely and let rise again until doubled, about 30–45 minutes.
- Preheat the oven to 375°F (190°C). Bake the loaf for 35–40 minutes, until golden brown and the internal temperature reads 190°F (88°C) (if using a thermometer). If the top browns too quickly, tent with foil.
- Remove from the oven and let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
Tips
- Use dry, fluffy mashed potatoes: Avoid watery or overly buttery mashed potatoes, as they can make the dough too wet. If using leftover mashed potatoes, ensure they are at room temperature.
- Substitute instant yeast: Use 1 3/4 teaspoons (5 g) instant yeast instead of active dry. Mix it directly with the flour, and skip the proofing step—just add the warm water to the dough.
- Check flour amount: Humidity and potato moisture vary, so add flour gradually. The dough should be soft but not sticky; adjust with a tablespoon of flour at a time.
- Store properly: Keep sliced bread in an airtight container or bread box at room temperature for up to 3 days. For longer storage, freeze slices.
Serving Suggestions
Serve potato bread sliced and lightly toasted with butter and jam for breakfast. It also makes excellent sandwiches—try it with ham and Swiss cheese, or as a base for avocado toast. For a savory twist, serve alongside soups or stews to soak up the broth.
Variations
- Herb Potato Bread: Add 1 tablespoon (15 ml) fresh rosemary or thyme, chopped, to the dough for an aromatic loaf.
- Whole Wheat Potato Bread: Replace half of the all-purpose flour with whole wheat flour for a heartier texture.
- Cheese Potato Bread: Fold in 1 cup (115 g) shredded cheddar cheese after the first rise for a cheesy pull-apart loaf.
- Sweet Potato Bread: Substitute mashed sweet potato for regular potato and reduce honey to 1 tablespoon (15 ml) for a subtly sweet, orange-tinted loaf.
Storage and Reheating
Store sliced potato bread in an airtight container or plastic bag at room temperature for up to 3 days. For longer storage, freeze slices in a single layer on a baking sheet, then transfer to a freezer bag; they’ll keep for up to 3 months. To reheat, toast frozen slices directly in a toaster, or warm in a 350°F (175°C) oven for 5–7 minutes. Refrigeration is not recommended, as it can dry out the bread.
Frequently Asked Questions
Can I use leftover mashed potatoes? Yes, but make sure they are plain (without added butter, milk, or salt) or adjust the flour accordingly. If they’re very wet, reduce the water by 2 tablespoons (30 ml).
Why didn’t my bread rise? The yeast may be dead if the water was too hot (over 120°F / 49°C) or too cold (under 105°F / 40°C). Always proof the yeast in warm water with sugar first. Also, ensure the mashed potatoes are not too cold—room temperature is best.
Can I make this bread without eggs? Yes, replace the egg with 3 tablespoons (45 ml) water or milk. The bread will be slightly less rich but still soft.
How do I get a soft crust? Brush the hot loaf with melted butter immediately after baking. This keeps the crust tender.
Can I shape this into rolls? Absolutely. After the first rise, divide the dough into 12 equal pieces, shape into balls, and place on a baking sheet. Let rise for 30 minutes, then bake at 375°F (190°C) for 15–18 minutes.
Is potato bread gluten-free? No, this recipe uses wheat flour. For a gluten-free version, use a 1:1 gluten-free flour blend, but the texture will be denser.
