Ingredients

Preferment (made 10 to 12 hours before mixing final dough)

  • 4 grams salt
  • 195 grams lukewarm filtered water
  • 90 grams dark rye flour (100% whole grain)
  • 100 grams all-purpose (white wheat) flour
  • 40 grams sourdough starter (rye or wheat)

Sponge (made 30 minutes before mixing final dough)

  • 200 grams lukewarm filtered water
  • 260 grams all-purpose (white wheat) flour

Main Dough

  • 70 grams lukewarm filtered water
  • 9 grams salt
  • 175 grams dark rye flour (100% whole grain)
  • 3 grams active dry yeast (½ pouch)

Zwiebelbrot (optional onion bread addition)

  • 1 large yellow onion
  • 14 grams butter

Instructions

  1. Make Preferment: In a medium bowl, combine 4 grams salt, 195 grams lukewarm water, 90 grams dark rye flour, 100 grams all-purpose flour, and 40 grams sourdough starter. Mix thoroughly with a rubber spatula or spoon until homogeneous. Cover airtight and let rest at room temperature for 10 to 12 hours to allow fermentation.
  2. Make Sponge: In a small bowl, combine 200 grams lukewarm water and 260 grams all-purpose flour by hand until smooth dough forms. Cover airtight and let rest at room temperature for 30 minutes to develop gluten.
  3. Prepare Onion (for Zwiebelbrot): Peel, slice, and cook 1 large yellow onion in 14 grams butter over medium-low heat for 10 to 15 minutes, stirring occasionally, until golden brown and moisture is mostly cooked out. Set aside to cool.
  4. Make Main Dough: Without premixing, add 70 grams lukewarm water, 9 grams salt, 175 grams dark rye flour, and 3 grams active dry yeast into the two pre-doughs (preferment and sponge). Optionally add the cooked onions here for Zwiebelbrot. Knead by hand or using a mixer dough hook for about 5 minutes until dough is homogenous and barely sticky.
  5. First Rise: Cover dough airtight and rest at room temperature for 1 hour until it increases by about 50% in size.
  6. Shape Dough: Shape the dough into a round or long loaf depending on your proofing basket. Fold the dough edges over the base, pressing down, and working all flaps into the center to create surface tension. Place the shaped dough seam side down into a proofing basket generously dusted with white flour.
  7. Proof: Cover the basket with a linen towel or liner and let dough proof at room temperature for 45 minutes.
  8. Preheat Oven: Preheat your oven to 250° Celsius (480° Fahrenheit). Place a casserole dish filled with hot water on the bottom rack to generate steam.
  9. Bake: Prepare a baking sheet lined with parchment paper. Gently invert the dough onto the parchment. Ensure there is adequate water in the casserole dish for steam. Transfer quickly to the hot oven and bake for 60 minutes. After 10 minutes, reduce oven temperature to 220° Celsius (430° Fahrenheit).

Notes

  • Dutch Oven Baking: To bake in a Dutch oven, preheat the oven and Dutch oven with the lid on at 250° Celsius (480° Fahrenheit). Do not add water for steam as the lid traps moisture. Remove lid, place dough on parchment inside the Dutch oven, score the loaf, replace lid, and bake 10 minutes. Lower heat to 220° Celsius (430° Fahrenheit) and bake 40 minutes more. Remove lid and bake an additional 10 minutes to brown crust.
  • Onion Version: When adding onions for Zwiebelbrot, ensure onions are golden brown and moisture is cooked out to prevent dough consistency changes.
  • Scoring: Scoring the loaf before baking is optional; it controls where cracks appear but is not required for this recipe.
  • Sourdough Tips: Consistent water temperature and flour quality significantly impact fermentation and flavor.
