Grease a large baking sheet with butter or non-stick cooking spray and set aside.
In the bowl of a stand mixer, combine the warm water, sugar, and yeast. Mix well, then let sit for 5-10 minutes, or until the yeast is frothy and bubbly.
Once the yeast has proofed, add the oil, salt, egg and half of the flour into the yeast mixture and mix on low using the dough hook until combined.
Continue adding one cup of flour at a time, then mixing on low speed, until the dough pulls away from the sides and looks smooth. Once all of your flour is added, knead on medium speed for about 3 minutes. It should look smooth and elastic.
Cover with plastic wrap and let rise in a warm place until doubled, about 30-45 minutes.
Once your dough has doubled, divide into 8 even pieces. Sprinkle flour on your counter, then using your hands, make each dough ball into a tight round ball.
Place the dough ball onto the greased baking sheet. Make an "x" or "hashtag" score in the dough with a sharp knife.
Whisk together the egg and water and brush a thin, even layer over the tops of each loaf of dough using a pastry brush. Let rise until doubled in size, about 30-45 minutes.
Preheat the oven to 400 degrees F. while the loaves are rising.
Bake your bread bowls for 25-30 minutes, or until golden brown. Remove from the oven and cool for about 10-15 minutes, or until they can be handled.
To serve as Bread Bowls, cut a large circle out of the top and scoop out the center. Add your favorite soup, and enjoy!
