Activate the yeast: Warm the water to 105 degrees F in the microwave or on the stove. Stir in the sugar until it dissolves, then add the active dry yeast and stir. Set aside for 5 minutes or until the yeast begins frothing. If there is no frothing, your yeast is bad and you need to try again with new yeast.
Whisk the flour mixture: Meanwhile, whisk together the gluten-free flour, psyllium husk powder, and salt.
Make the dough: Make a well in the center of the flour mixture and add the water and yeast mixture. Stir together using a wooden spoon. When stirring becomes difficult, add the oil and continue mixing. When stirring becomes difficult again, lightly flour your hands (with gluten-free flour) and continue mixing the dough until it is uniform. Then let it rest for 5 minutes while the flour and psyllium husk powder absorb the liquid.
Knead: Lightly dust a smooth surface with gluten-free flour and dust your hands with flour as well. Scoop up the dough and begin kneading, just like you would with traditional bread. You will need to knead this dough for 15-20 minutes before it passes the standard tests for properly kneaded dough. These include the poke test and the "window test". See the Expert Tips section of the blog post for more info on kneading and the poke and window tests if you are new to this skill. This bread dough will go through a phase of being very sticky about 10 minutes in. You need to continue kneading through this sticky phase. Lightly flour your hands as needed, but don't overdo it.
Oil and form a loaf: When the dough passes the kneading tests, pour and spread just a little bit of oil (about ½ teaspoon is fine) along the bottom of the original mixing bowl. Place your dough ball in the bowl and gently turn the ball so that all sides are very lightly coated with oil. When finished, set in the bowl with any seams on the bottom.
Let rise: Loosely cover the dough and bowl with a towel and set in a warm place to rise for 2 hours or until the loaf has doubled in size. See notes for suggestions if your house is cold. As you near the end of the rising time, place your oven racks in the middle and bottom of your oven and preheat the oven to 475 degrees F. Lightly grease a large baking sheet with olive oil.
Score: Very gently transfer the dough to the prepared baking sheet. Then, using a bread lame, razor blade, or very sharp knife, score the bread in whatever pattern you like! I did a simple criss cross pattern in my photos but this loaf can definitely handle a bit more artistry. Make cuts about ¼ inch thick to just break the taught outer layer.
Bake: On the bottom rack of the oven, place a deep baking pan with 1 -1 ½ cups of boiling water. On the rack above it, place your bread loaf. Keep the oven solidly closed and bake the loaf at 475 degrees F for 20 minutes. Then remove the pan of water and reduce the temperature to 425 degrees F for an additional 40 minutes, or until the loaf is finished baking. You know the artisan bread is finished baking when the crust is solidly golden brown in color, tapping a fingernail on the crust creates a hollow sound, and the internal temperature of the loaf is 190 degrees F (temperature is the most accurate test for doneness).
Cool: Allow the loaf to cool on the pan for 10 minutes. Then gently transfer to a cooling rack to cool completely before slicing and eating.
