In a large bowl, combine warm water, sugar, and instant yeast. Stir and let it sit for 5 minutes until foamy.

Add melted butter, salt, and egg to the yeast mixture. Mix well.

Gradually add flour, 1 cup at a time, mixing until a soft dough forms.

Knead the dough on a floured surface for about 5-7 minutes until smooth and elastic.

Divide the dough into 12 equal pieces.

Shape each piece into a ball and place them on a greased baking tray, evenly spaced apart.

Cover the tray with a clean kitchen towel and let the rolls rise in a warm place for about 30 minutes, or until doubled in size.

Preheat your oven to 375°F (190°C).

Place the tray in the lowest rack of the oven to prevent over-browning.

Tent the top of the rolls with aluminum foil to prevent excessive browning.

Bake for 18-20 minutes, or until the tops are golden brown.

Remove from the oven and let cool slightly before serving.
