To make fluffy potato rolls for dinner, you can follow this recipe:
Ingredients:
- 4 cups all-purpose flour
 - 1 cup mashed potatoes (cooled)
 - 1/4 cup unsalted butter, melted
 - 1/4 cup granulated sugar
 - 1 cup warm milk (110°F/45°C)
 - 1 large egg
 - 2 1/4 teaspoons (1 packet) active dry yeast
 - 1 teaspoon salt
 - Additional melted butter for brushing (optional)
 
Instructions:
- In a small bowl, dissolve the yeast in the warm milk. Let it sit for about 5-10 minutes until frothy.
 - In a large mixing bowl or the bowl of a stand mixer, combine the mashed potatoes, melted butter, sugar, salt, and egg. Mix well.
 - Add the yeast mixture to the potato mixture and stir to combine.
 - Gradually add the flour, one cup at a time, mixing until a soft dough forms.
 - Knead the dough on a floured surface or with a dough hook attachment for about 5-7 minutes, or until the dough is smooth and elastic.
 - Place the dough in a greased bowl, cover it with a clean kitchen towel, and let it rise in a warm place for about 1-2 hours, or until doubled in size.
 - Punch down the dough and divide it into equal-sized portions. Shape each portion into a ball and place them in a greased baking pan, leaving some space between each roll.
 - Cover the rolls with a kitchen towel and let them rise again for about 30-45 minutes, or until they double in size.
 - Preheat your oven to 375°F (190°C).
 - Bake the rolls in the preheated oven for 15-20 minutes, or until they are golden brown on top and sound hollow when tapped on the bottom.
 - Remove the rolls from the oven and brush the tops with melted butter, if desired.
 - Let the rolls cool slightly before serving.
 
Enjoy your fluffy potato rolls with dinner or as a delicious snack any time of the day!
