Prep Time 10 hours 25 minutes
Cook Time 40 minutes
Resting Time 1 hour
Total Time 12 hours 5 minutes
Course Bread
Cuisine European
Servings 1 loaf (8–10 slices)

Equipment

  • 1 digital kitchen scale
  • 2 medium mixing bowls
  • 1 large mixing bowl
  • 1 Dough scraper
  • 1 Wooden spoon or spatula
  • 1 proofing basket or 1 medium bowl lined with a floured kitchen towel
  • 1 cast-iron Dutch oven with lid (4–5 qt)
  • 1 sharp lame or serrated knife
  • 1 clean spray bottle (optional)
  • 1 wire cooling rack

Ingredients
  

  • 100 gram active sourdough starter 100% hydration
  • 375 gram water room temperature
  • 450 gram bread flour
  • 50 gram whole wheat flour
  • 10 gram fine sea salt
  • 25 gram raw sunflower seeds toasted
  • 25 gram raw pumpkin seeds toasted
  • 20 gram sesame seeds toasted
  • 10 gram flaxseeds
  • 10 gram rolled oats
  • 10 gram honey optional
  • 10 gram olive oil for bowl and hands
  • 10 gram mixed seeds extra for topping

Instructions
 

  • In a large mixing bowl, whisk together the active sourdough starter and water until mostly dissolved.
  • Add the bread flour and whole wheat flour to the bowl and mix until no dry flour remains, then cover and rest for 30–45 minutes (autolyse).
  • Sprinkle the salt and honey over the dough and mix with wet hands or a spatula until fully incorporated.
  • In a dry skillet over low heat, lightly toast the sunflower seeds, pumpkin seeds, and sesame seeds until fragrant, then let them cool.
  • Add the cooled toasted seeds, flaxseeds, and rolled oats to the dough and gently fold until evenly distributed.
  • Cover the bowl and let the dough bulk ferment at room temperature for 3–4 hours, performing 3–4 sets of stretch-and-folds every 30–45 minutes during the first 2 hours.
  • After bulk fermentation, lightly oil your hands and work surface, then turn the dough out and gently pre-shape it into a loose round.
  • Let the pre-shaped dough rest on the counter, covered, for 20–30 minutes to relax.
  • Shape the dough into a tight round or oval loaf, creating surface tension without tearing the skin.
  • Lightly flour the proofing basket or towel-lined bowl, then place the dough seam side up into the basket.
  • Cover the basket and proof at room temperature for 1–2 hours, or refrigerate for 8–12 hours for a slow cold proof.
  • About 45 minutes before baking, place the Dutch oven with its lid into the oven and preheat to 475°F (245°C).
  • When ready to bake, carefully remove the hot Dutch oven, gently invert the dough onto a piece of parchment or directly into the pot so it is seam side down.
  • Lightly mist or brush the top of the dough with water and sprinkle the extra mixed seeds evenly over the surface, pressing gently so they adhere.
  • Score the top of the loaf with a lame or sharp knife to allow controlled expansion.
  • Cover the Dutch oven with its lid and bake for 20 minutes at 475°F (245°C).
  • Remove the lid, reduce the oven temperature to 450°F (230°C), and continue baking for 18–22 minutes or until the crust is deeply golden and the loaf sounds hollow when tapped.
  • Carefully transfer the baked bread to a wire rack and let it cool completely for at least 1 hour before slicing.

Notes

For best results, use an active, bubbly starter that has recently peaked; sluggish starter will lengthen fermentation and can lead to dense bread. Adjust fermentation time based on room temperature: warmer kitchens shorten bulk and proof times, while cooler ones lengthen them, so rely on dough cues (a smoother surface, 50–75% volume increase, and airy feel) rather than the clock. Hydration and seeds can vary by brand, so if the dough feels very wet, give it extra folds instead of adding a lot more flour. Toasting seeds intensifies flavor and reduces chewiness, but cool them fully before adding or they can overheat the dough. A cold-proofed loaf is easier to score and often yields better oven spring. Always cool the bread thoroughly before slicing to avoid a gummy interior, and store it cut side down on a board or in a paper bag to keep the crust crisp.
