Add the quick oats to a large mixing bowl or your stand mixer bowl. Pour the boiling water over the oats and let it sit for about 10 minutes.
1 3/4 cups quick-cooking oats, 1 3/4 cups boiling water
Meanwhile, dissolve the yeast in warm water. Set aside.
2 scant tablespoons active dry yeast dissolved in 1/2 cup warm water
Add the honey to the oats and mix. Add the milk, oil, and egg yolk, and mix again.
1/2 cup honey or molasses, 1/2 cup milk, 1/3 cup canola or vegetable oil, 1 egg yolk
Mix the dissolved yeast into the oat mixture.
Add the salt and 5 cups of bread flour. Mix to create a dough.
2 teaspoons salt, approx. 6 cups bread flour
Knead the dough on speed 2 with the dough hook attachment (or by hand on a floured surface) adding more flour as needed.
Knead until smooth and elastic and the sides of the bowl are clean. By hand, it will take approximately 8 - 10 minutes of kneading. With your mixer, it takes approx. 4 - 5 minutes.
Place the dough into a large well-greased bowl. Cover with a dish towel and set at room temperature to rise until doubled. It takes about an hour.
Grease three 9x5" loaf pans with cooking spray.
After the dough has risen, punch it down. With buttered hands knead the dough for a bit to release air bubbles. Divide it into three pieces.
Shape the dough into loaves and poke them a few times with a fork to avoid having air pockets. Place the loaves into prepared pans, cover them with a dish towel, and set aside to rise again (approx. 35 - 45 minutes depending on the temperature in your kitchen).
Preheat the oven to 350℉.
Once the bread has risen about a half inch up over the sides of the pan, it is ready to bake. (If you like really tall loaves, you can let them rise longer.)
Bake for 30 - 35 minutes or until the tops are golden brown.
If desired, spread butter over the tops of the loaves to soften the crust. Let the bread rest in the pans for approximately 10 minutes.
Remove the loaves to a wire rack to cool. Enjoy a few slices of warm bread, and then store the remaining loaves in airtight bags or containers. (I bag my bread before it's completely cool, it helps to retain moisture and keep it softer.)
Freeze any loaves that won't get eaten within four days.
