Steps

Before you start

Have all ingredients at room temperature (65–75°F), including milk and eggs
Prep mashed potatoes ahead if needed; they should be smooth and cooled
Preheat oven to 375°F (190°C) about 15 minutes before baking

1
Boil and mash potatoes
- Place cubed potatoes in a saucepan, cover with cold salted water, and bring to a boil.
- Simmer for 10–12 minutes until fork-tender.
- Drain well in a colander, then transfer to a bowl and mash until smooth.
- You should have roughly ¾ cup (180 g) of mashed potato.
- Spread on a plate to cool to room temperature, about 10–15 minutes.

Ready when: Potatoes are smooth and cool, not steaming
Tip: Overcooking potatoes makes them watery; drain very well and mash immediately.
2
Bloom yeast
- In a large mixing bowl or the bowl of a stand mixer, combine the warmed milk, yeast, and sugar.
- Stir gently and let sit for 5–7 minutes until the mixture is foamy and fragrant.
- This proves the yeast is alive.

Ready when: Mixture is foamy and slightly domed on top
Tip: Milk that is too hot (above 120°F) will kill yeast; too cool and it won't activate.
3
Mix dough
- Add the cooled mashed potatoes, softened butter, and egg to the yeast mixture.
- Using a stand mixer on low speed (or by hand with a wooden spoon), mix for 1 minute until combined.
- Add the flour and salt, then mix on low speed for 2 minutes.
- The dough will come together but remain sticky.

Ready when: All flour is incorporated; dough is shaggy and sticky but holds together
Tip: Do not overmix at this stage or the rolls will be tough. Potato water content varies, so flour amounts may need tiny adjustments.
4
Knead the dough
- Increase mixer speed to medium and knead for 6–8 minutes (or knead by hand for 10–12 minutes) until the dough is smooth, elastic, and slightly tacky but no longer sticking to the bowl.
- It should pull away cleanly from the sides.
+ Show details− Hide details
Ready when: Dough is smooth, springs back slowly when poked, and forms a ball
Tip: The dough may seem wet; resist adding extra flour unless it clings thickly to the hook. Potato rolls are naturally moister than plain rolls.
5
First rise
- Shape the dough into a ball, place it in a lightly oiled large bowl, and turn to coat.
- Cover loosely with plastic wrap or a damp kitchen towel.
- Let rise in a warm, draft-free place for 60–75 minutes, or until doubled in volume.

Ready when: Dough fills the bowl and springs back slowly when lightly poked
Tip: A warm oven with the light on, or a proofing box set to 75–80°F, speeds rising. Avoid draughts.
6
Shape rolls
- Turn the risen dough onto a lightly floured counter.
- Using a bench scraper or knife, divide the dough into 12 equal pieces (each roughly 2 oz / 55 g).
- Working with one piece at a time, gently cup your palm around the dough and roll it toward you, creating tension on the surface.
- Place each roll seam-side down into a buttered 9-inch round cake pan or 9×13-inch baking pan (6 rolls per 9-inch pan, or arrange in a single layer in the larger pan).
- Space them about ½ inch apart.

Ready when: Rolls are smooth balls arranged in pans with slight gaps between them
Tip: Tight rolling creates surface tension and helps rolls rise vertically. If dough springs back, rest it 2 minutes and try again.
7
Second rise
- Cover the pans with plastic wrap or damp towels.
- Let the rolls rise in a warm place for 45–50 minutes until they are puffy, light, and nearly touching each other.
- They should look noticeably larger but not over-risen.
+ Show details− Hide details
Ready when: Rolls are visibly puffy and nearly touching each other; a gentle poke leaves a slow-filling indent
Tip: Rolls that over-proof (rise too much) will collapse in the oven. If they look too tall, begin baking early.

Bake rollsOven 375°F / 190°C
- Preheat your oven to 375°F (190°C).
- Once preheated and rolls are ready, place the pans on the middle rack.
- Bake for 22–26 minutes until the rolls are golden brown on top and the bottoms are light golden (check by carefully tilting a pan).
- The rolls should feel firm, not jiggly.
+ Show details− Hide details
Ready when: Tops are deep golden brown; rolls feel firm and sound hollow when tapped
Tip: If tops brown too quickly, tent with foil. Rolls continue cooking slightly after removal, so don't wait for a very dark brown.
9
Cool and finish
- Remove pans from the oven and immediately brush the warm rolls with melted butter, applying it over all the tops and sides.
- Let the rolls cool in the pan for 5–10 minutes, then turn out onto a wire rack to cool further.
- Serve warm or at room temperature.

Ready when: Butter is absorbed; rolls are cool enough to handle but still warm
Tip: Brushing hot rolls with butter ensures even absorption and gives a soft crust.

Tips

If your dough seems too sticky after mixing, trust the recipe—potato dough is naturally moister. Adding extra flour is the #1 cause of dense, dry rolls.
For softer, whiter rolls, brush with melted butter and a pinch of salt immediately after baking. For a glossier finish, brush with an egg wash (1 egg beaten with 1 tablespoon water) before baking.
Room temperature is key: cold ingredients slow yeast activity and uneven rises. Place ingredients (especially butter and eggs) on the counter 1 hour ahead.
These rolls freeze beautifully; shape and freeze unbaked, then add 5–10 extra minutes to the baking time when baking from frozen.

Make ahead

You can prepare the dough through the first rise and refrigerate it overnight (covered, in the fridge). The next morning, shape, allow a 60-minute room-temperature second rise, then bake as directed. Alternatively, freeze shaped, unbaked rolls on a baking sheet, then transfer to a freezer bag for up to 3 weeks. Thaw overnight in the fridge, let them come to room temperature, and bake.

Storage & reheating

Store cooled rolls in an airtight container at room temperature for up to 2 days. They will remain soft and fresh. Refrigerate in a sealed container for up to 5 days; reheat gently in a 300°F (150°C) oven, wrapped in foil, for 8–10 minutes. Freeze baked rolls in a freezer bag for up to 1 month; thaw at room temperature and warm in a 300°F oven for 10–12 minutes.

Substitutions

whole milk, warmed → Buttermilk or half-and-half, warmed. Buttermilk adds tanginess and makes rolls slightly more tender. Use the same volume. If using half-and-half, reduce by 1 tablespoon to account for richness.
russet potatoes, peeled and cubed → Instant mashed potato flakes (¼ cup/15 g) mixed with ¼ cup (60 ml) warm water. A quicker shortcut; let the mixture rest 2 minutes before adding. Texture will be slightly lighter.
all-purpose flour → Bread flour. Use the same weight. Bread flour develops more gluten and will give rolls a slightly chewier crust; reduce water if dough seems wet.
granulated sugar → Honey (1 tablespoon / 21 g). Adds subtle sweetness and helps with browning. The dough will be slightly stickier; no other changes needed.
