Mix both flours, salt, yeast, and seeds into a large mixing bowl. Stir to combine.
In a separate vessel, add the agave to the warm water and stir until fully dissolved. Pour into the dry ingredients.
Mix until no streaks of flour remain. This should only take about 1 minute.
Cover the bowl with a towel or plastic wrap and let rest on the kitchen counter for 3 hours.
After the first rise, the dough will have at least doubled in size. Coat the top lightly in oil, and punch the air holes out of the dough (pictured above).
Fold the dough onto itself a few times and form it into a rough loaf-shape.
Transfer the dough to a parchment-lined (or oiled) loaf pan and let rest another 40-minutes to 1 hours.
Preheat the oven to 375.
Once the loaf has risen to about 1 inch above the sides of the loaf pan, bake for 30-40 minutes or until the top is evenly golden brown.
Remove from the oven and carefully turn the loaf out of the loaf pan.
Let cool on a cooling rack at least 30 minutes before slicing. If you are storing the loaf right away, let cool fully beforehand (1-2 hours).
Enjoy!
