These soft and fluffy potato rolls are made with mashed potatoes for an ultra-tender texture. Perfect for any meal, they’re easy to make and sure to become a family favorite!
Heat water, milk, and butter until very warm (120° to 130°F/49° to 54°C). Stir into flour mixture.
Stir in the potatoes, 1 egg, and enough of the remaining flour to make a soft dough.
Transfer the dough to a lightly floured surface. Knead until smooth and elastic (4-6 minutes). Cover and let rest for 10 minutes.
Divide the dough into 12 equal pieces.** Roll each piece into a ball. Place the rolls in a greased 9"x 13" baking pan.
Fill a large, shallow pan halfway with boiling water. Place a wire rack on top of the pan. Place the pan of rolls on top of the rack. Cover and let rise until doubled in size (about 15 minutes).
Preheat oven to 375°F (190°C).
Lightly beat 1 egg, and brush over the tops of the rolls. (You won't use all of the egg.)
Bake 25 to 27 minutes, or until golden brown. Cool the rolls in the pan on a wire rack.
Notes
*If you would prefer to use instant potato flakes instead of cooked potatoes, you'll need 1/4 cup of potato flakes and an extra 1/4 cup of water. Stir the potato flakes into the very warm milk mixture and let them soak for 1 minute. Follow the rest of the directions as normal.
**I highly recommend dividing the dough by weight. Weigh the dough in grams, divide the weight by 12, and then portion each dough by weight.
