Mix Ingredients: In a large mixing bowl, whisk together the whole wheat flour and salt. If using, add the vital wheat gluten and mix well. Pour in the oil, water, yeast, and honey. Mix until a shaggy dough forms. If it is dry and not forming a ball, add a small amount of water. If it is too wet and sticking to the bowl, add a small amount of flour.
Knead the Dough: Knead by stand mixer, bread machine or by hand, until the dough is smooth and elastic. This will take longer than white bread recipes. I let my mixer knead for about 10 minutes, and you need about 15-20 minutes if kneading by hand. When the dough is smooth and stretchy, shape into a ball.
First Rise: Place the kneaded dough in a lightly oiled bowl, turning once to coat. Cover with a damp cloth or plastic wrap. Allow it to rise in a warm place for 1 to 1 1/2 hours, or until it has doubled in size. Again, this will be slower than with white bread recipes.
Shape: Shape the dough into a loaf by folding it into thirds and then rolling it gently. Pinch the seams closed. Place it into a greased 9x5 inch loaf pan, seam side down.
Second rise: Cover again with a damp cloth or plastic wrap and allow to rise for 45-60 minutes. Towards the end of the rising time, preheat your oven to 350℉.
Bake: Once the dough has risen for the second time, place the loaf pan in the preheated oven. Bake for 30-35 minutes, or until the bread has a golden-brown crust and sounds hollow when tapped on the bottom. Remove the bread from the oven and transfer to a wire rack to let it cool completely before slicing.
