In the bowl of a stand mixer, whisk together the milk, sugar and yeast. Cover bowl and set aside for 8-10 minutes. Yeast mixture is ready to use when it appears bubbly.
Add the melted butter, flour and salt into bowl with yeast mixture. With the dough hook attached to the stand mixer, form and knead the dough until a soft, smooth dough forms, about 5-6 minutes.
Transfer bread dough to a large greased mixing bowl, cover with plastic wrap and set in a warm area to rise for 60-90 minutes or until doubled in size.
Punch down risen dough. Let the dough rest for 5 minutes. On a floured surface, roll dough into a rectangle. Starting on the short end of the rectangle, roll the dough onto itself to form a log. Pinch the seams close. Transfer the log seam side down into a greased loaf pan. Loosely cover with plastic wrap.
Place loaf pan in a warm area to allow the shaped dough to rise about a 1/2 inch over the lip of the loaf pan, about 30-40 minutes or less. Preheat oven to 375F.
In a small dish, whisk together the egg and teaspoon of water. Using a pastry brush, generously apply the egg wash over the risen dough. Bake for 25-30 minutes or until golden brown and a toothpick inserted into the bread comes out clean.
Let the bread ret in the pan for 5 minutes after removing from the oven. Transfer to a wire cooling rack to completely cool to room temperature before slices and using in your favorite sandwich recipes.
