In a large mixing bowl, whisk together the flour, sugar, salt, and instant yeast.

Create a well in the center of the dry ingredients and pour in the warm water and melted butter.

Using a wooden spoon or dough hook, mix until a shaggy dough forms.

Transfer the dough to a floured surface and knead for about 8-10 minutes until smooth and elastic.

Place the dough in a greased bowl and cover it with a kitchen towel. Let it rise in a warm area until it doubles in size, about 1 hour.

After the dough has risen, punch it down to release air bubbles. Shape it into a loaf.

Place the shaped dough into a greased loaf pan and cover it again. Let it rise for another 30 minutes.

Preheat your oven to 375°F (190°C). Bake the bread for 30 minutes or until golden brown.
