1. 1. Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, rolled oats, mixed seeds, salt, and instant yeast until well combined. This ensures all the dry components are evenly distributed.

2. 2. Mix Wet Ingredients: In a separate small bowl or measuring cup, combine the warm water, honey (or maple syrup), and olive oil. Stir gently to dissolve the honey. Ensure the water isn’t too hot, as it can kill the yeast, or too cold, which will slow down activation.

3. 3. Form the Dough: Pour the wet ingredients into the bowl with the dry ingredients. Using a wooden spoon or a sturdy spatula, mix until all the flour is hydrated and a shaggy, sticky dough forms. There’s no need to knead; just ensure there are no dry pockets of flour.

4. 4. First Rise (Overnight): Cover the bowl tightly with plastic wrap or a clean kitchen towel. Let the dough rise at room temperature (ideally 68-72 F) for 12-18 hours, or until it has doubled in size and the surface is bubbly. The longer the rise, the more flavor will develop.

5. 5. Prepare for Baking: Once the dough has risen, gently scrape it out onto a lightly floured surface. Fold the edges of the dough towards the center a few times to create a rough ball shape. Do not overwork the dough. Lightly grease a Dutch oven or an oven-safe pot with a lid (around 6-quart capacity) with olive oil. Sprinkle a few oats and seeds on the bottom.

6. 6. Second Rise and Preheat Oven: Carefully transfer the dough ball into the prepared Dutch oven. Sprinkle the top with more oats and seeds. Cover the Dutch oven with its lid and let it rest for 30 minutes while your oven preheats to 450 F (230 C). This short second rise helps the bread achieve a good spring in the oven.

7. 7. Bake the Bread: Place the covered Dutch oven into the preheated oven. Bake for 30 minutes with the lid on. This traps steam, creating a fantastic crust. After 30 minutes, remove the lid and continue baking for another 15-20 minutes, or until the crust is deeply golden brown and the internal temperature reaches 200-210 F (93-99 C).

8. 8. Cool Completely: Carefully remove the bread from the Dutch oven and transfer it to a wire rack. Let it cool completely for at least 1 hour before slicing. Slicing warm bread can make it gummy and prevent it from setting properly.
