1. In a large mixing bowl, combine warm milk, sugar, and yeast. Let it sit for about 5 minutes until frothy.
2. Add melted butter, egg, and salt to the yeast mixture. Mix well.
3. Gradually add flour, one cup at a time, until a soft dough forms.
4. Knead the dough on a floured surface for about 5-7 minutes until smooth and elastic.
5. Place the dough in a greased bowl, cover, and let it rise in a warm place for about 1 hour or until doubled in size.
6. Punch down the dough and divide it into 12 equal pieces. Shape each piece into a ball and place on a greased baking sheet.
7. Cover and let the rolls rise for another 30 minutes.
8. Preheat the oven to 375°F (190°C). Bake the rolls for 12-15 minutes or until golden brown.
