A simple, no-knead overnight sourdough discard sandwich bread loaded with mixed seeds, perfect for fresh homemade sandwiches with a crunchy crust and wholesome flavor.

Ingredients

Scale
  • 100g (3.5 oz) sourdough discard
  • 350g (2 ¾ cups) all-purpose flour
  • 300ml (1 ¼ cups) warm water (around 75°F / 24°C)
  • 1 ½ tsp salt
  • 1 tbsp honey or maple syrup
  • 3 tbsp mixed seeds (sesame seeds, poppy seeds, sunflower seeds; optional flaxseeds or pumpkin seeds)
  • 1 tbsp olive oil or melted butter (optional)

Instructions

  1. Mix the dough (10 minutes): In a large bowl, combine sourdough discard, warm water, and honey or maple syrup. Stir gently until discard is mostly dissolved. Add flour and salt, mix until a shaggy dough forms.
  2. First rise (overnight or 8-12 hours): Cover bowl loosely with plastic wrap or damp towel. Leave on countertop or warm spot overnight to ferment and rise.
  3. Shape the dough (10 minutes): Lightly flour work surface. Gently scrape dough out and fold over itself a few times to shape into a rough round or oval.
  4. Prepare baking vessel and seeds (5 minutes): Preheat oven to 450°F (230°C) with Dutch oven inside. Brush dough top lightly with water or olive oil, sprinkle mixed seeds evenly, pressing gently.
  5. Second rise (30-45 minutes): Let shaped dough rest while oven heats until it puffs slightly.
  6. Bake the bread (35-40 minutes): Place dough inside hot pot (use parchment paper if needed). Cover with lid and bake 20 minutes. Remove lid and bake another 15-20 minutes until crust is deep golden and crisp.
  7. Cool completely (at least 1 hour): Transfer bread to wire rack to cool before slicing.

Notes

Use active sourdough discard fed within last few days. Lukewarm water helps yeast activity. Let bread cool completely before slicing to avoid gummy crumb. If dough is sticky, add a little flour during shaping but avoid overdoing it. Oven temperatures vary; tent with foil if crust browns too quickly. If no Dutch oven, bake on preheated baking stone with pan of water for steam.
