Step 1

In a large bowl, combine the oats, boiling water, maple syrup, and salt. Let stand for 10 minutes. Add the remaining 3/4 cup (170 g) water and stir to combine. Add the instant yeast, and stir to combine. Finally, add the flours and stir with a rubber spatula, until the liquid is absorbed and the ingredients form a sticky dough ball. You may need to knead the dough with your hands briefly to help the dough come together, no more than 15 to 30 seconds.

Step 2

Cover the bowl with a tea towel or plastic wrap and set aside in a warm spot to rise for 2 to 3 hours, until the dough has doubled in volume.

Step 3

Preheat the oven to 375ºF. Grease an 8.5- x 4.5-inch (or 9×5-inch) loaf pan generously with softened butter. Pour the remaining 1/2 cup of oats into the loaf pan and turn the pan so that the oats coat the pan on all sides. Pour out the remaining oats and set aside.

Step 4

When the dough has doubled, drizzle the tablespoon of olive oil over the top and use your hand to rub the oil over the surface to coat. Use your hand again to release the dough from the sides of the bowl, then flip the ball over so that the oil side is down. Roll the dough into a coil or into a loaf shape (see video in the post above), then transfer to your prepared pan seam side down. Pour the reserved oats over the top, then spread with your hand or shake the pan to distribute them.

Step 5

Let the dough rise on the countertop (preferably in a warm, draft-free spot) for 45 minutes to an hour or until the dough has risen significantly in the pan — it should be doming above the rim of the pan by about one inch. See photos for reference.

Step 6

Transfer the pan to the oven and bake for 45 minutes, or until the top is evenly browned. Remove the pan from the oven and turn the loaf out onto a cooling rack. Let the loaf cool for at least 30 minutes before slicing.
