Pour water in a measuring cup and heat it until it's luke warm.
Stir yeast and sugar. Cover and let it sit for about 5 minutes or until the yeast activates. If the yeast doesn’t activate, dump the entire mixture and start over again.
Once yeast is activated, add oats, flax and flour in a mixing bowl along with salt and oil.
Give it a mix and make a well in the center.
Pour the activated yeast into the well. Using a rubber spatula, give it a mix to form a rough dough.
Now, if you are using a stand mixer, attach the dough hook and knead at speed 3 for 12 minutes.
If you kneading by hand, scrape the dough in a lightly floured countertop or a wooden board and knead until it’s smooth and elastic. It should take about 12 minutes.
Once the dough is ready, make a rough round ball
Place it either in the same mixing bowl or a separate one that's lightly brushed with oil.
Cover it with clear wrap and keep it in a warm place. Give it a couple of hours to rise and double in size.
Once the bread dough rises and doubles in size, scrape it carefully on to a board.
Fold it from the sides and form a rectangular shape.
Place it on the bread-baking pan and sprinkle some oats on top.
Cover it with clear wrap and keep it in a warm place for a second rise.
Finally, pre-heat the oven to 375F and bake the bread for about 40 to 45 minutes.
