Why You’ll Love This Recipe

This sourdough maple oat sandwich bread is more than just a loaf—it’s a versatile canvas for your favorite sandwich fillings and a comforting companion to soups and salads. Here’s why it stands out:

  • Natural Leavening: Uses a sourdough starter for a tangy depth of flavor and improved texture.
  • Wholesome Ingredients: Rolled oats and maple syrup bring nutrition and subtle sweetness without refined sugars.
  • Soft Yet Hearty: The crumb is tender enough for sandwiches but has a satisfying chew thanks to the oats.
  • Long Shelf Life: The sourdough fermentation and oats help keep the bread moist and fresh longer.
  • Perfect for Sandwiches: Slices hold up well with all kinds of fillings, from savory to sweet.

Ingredients

  • Levain:
    • 50g active sourdough starter
    • 100g whole wheat flour
    • 100g water (room temperature)
  • 400g bread flour
  • 100g rolled oats (plus extra for topping)
  • 300g water (lukewarm)
  • 60g maple syrup
  • 10g salt
  • 30g unsalted butter, softened

Equipment

  • Large mixing bowl
  • Dough scraper
  • Kitchen scale
  • Proofing basket or loaf pan
  • Clean kitchen towel or plastic wrap
  • Oven with steam capability (or a tray for water)
  • Baking sheet or Dutch oven
  • Cooling rack

Instructions

  1. Prepare the levain: The night before baking, mix the 50g sourdough starter, 100g whole wheat flour, and 100g water in a small bowl. Cover loosely and let it ferment overnight at room temperature.
  2. Mix the dough: In a large bowl, combine 400g bread flour, 100g rolled oats, and 10g salt. In a separate bowl, whisk 300g lukewarm water and 60g maple syrup until blended.
  3. Add the levain to the water and maple syrup mixture and stir to combine.
  4. Pour the wet ingredients into the dry ingredients. Mix gently until just combined, forming a shaggy dough. Cover with a towel and let it rest for 30 minutes (autolyse).
  5. Knead and incorporate butter: Add the 30g softened butter to the dough. Knead or stretch and fold the dough in the bowl for about 8-10 minutes until it becomes smooth and elastic.
  6. Bulk fermentation: Cover the dough and let it ferment at room temperature for 4-5 hours. Every 30 minutes during the first 2 hours, perform a set of stretch and folds to develop gluten. The dough should rise noticeably and feel airy.
  7. Shape the dough: Turn the dough out onto a lightly floured surface. Shape it into a tight loaf suitable for your proofing basket or loaf pan. Sprinkle some oats on top and gently press them in.
  8. Final proof: Place the shaped dough into the proofing basket or pan. Cover and refrigerate overnight (8-12 hours) for slow fermentation and flavor development.
  9. Preheat the oven: The next morning, preheat your oven to 230°C (450°F). If using a Dutch oven, preheat it as well.
  10. Bake the bread: Carefully transfer the loaf onto a baking sheet or into the Dutch oven. Add a small tray of water to the oven bottom for steam or create steam by spraying water on the oven walls.
  11. Bake for 20 minutes with steam, then remove the steam tray or lid and bake for another 20-25 minutes until the crust is deep golden brown.
  12. Cool: Remove the bread from the oven and transfer to a cooling rack. Let it cool completely before slicing to ensure the crumb sets properly.

Tips & Variations

“Patience is key when working with sourdough. Allowing the dough to ferment slowly overnight creates a more complex flavor and better crumb.”

  • Use steel-cut oats instead of rolled oats for a nuttier texture.
  • Swap maple syrup with honey or agave nectar for a different sweetness profile.
  • Incorporate seeds like sunflower or pumpkin seeds into the dough for extra crunch and nutrition.
  • Try baking in a loaf pan for a perfectly shaped sandwich bread or freeform for a rustic look.
  • For a gluten-free option, experiment with gluten-free sourdough starter and flours, though texture will differ.
