In a stand mixer bowl, add yeast, sugar, and hot water. Allow to proof for five minutes.
Stir in egg, flour, salt, and one tablespoon softened butter. From here, allow stand mixer to mix the ingredients on a low speed for 4 minutes, until a soft dough is formed.
Cover the bowl and allow to rest and rise for an hour and a half.
After the dough has risen, turn the dough out onto a lightly floured surface.
Cut dough into 9-16 equal pieces, depending on your family likes their rolls.
Place on a jelly roll pan lined in parchment paper or silicone cookie sheet liners.
Cover and allow them to rest an additional hour, until they double in size.
Preheat the oven to 375 degrees. Uncover rolls and brush with melted butter. Bake for 15-18 minutes, until golden brown.
