1. In a small bowl, combine the warm water, and yeast. Stir gently and let it sit for about 5 minutes until the yeast becomes frothy.
2. In a large mixing bowl, whisk together the gluten-free all-purpose flour, xanthan gum, and salt.
3. Pour the yeast mixture into the bowl of dry ingredients. Add the oil. Stir everything together until a sticky dough forms. The dough will be wetter and stickier than traditional bread dough.
4. Cover the bowl with a clean kitchen towel or plastic wrap and let the dough rise in a warm place for about 1 hour. The dough should double in size.
5. Preheat your oven to 425°F (220°C). Place a Dutch oven or oven-safe pot with a lid into the oven while it preheats.
6. Sprinkle some additional gluten-free flour onto a clean surface. Carefully transfer the risen dough onto the floured surface. Shape the dough into a round loaf, gently folding and tucking the edges underneath to create a smooth top.
7. Carefully remove the preheated Dutch oven from the oven. Remove the lid and place the shaped dough into the hot pot. Be cautious as the pot will be very hot.
8. Cover the pot with the lid and bake for 30 minutes. Then, remove the lid and continue baking for an additional 10-15 minutes, or until the bread is golden brown.
9. Once baked, carefully remove the bread from the pot and place it on a wire rack to cool completely before slicing.
