Ingredients

Dough Ingredients

  • cups (300 ml) warm water
  • teaspoons (7g) instant or active dry yeast (1 standard packet)
  • 1 tbsp granulated sugar
  • ½ cup (125g) sourdough discard (100% hydration, room temp)
  • 1 tsp table salt
  • 1 tbsp (14g) unsalted butter, melted and slightly cooled
  • 4 cups (500g) all-purpose flour

For Boiling

  • 8 cups (1920 ml) water
  • ½ cup (120g) baking soda

For Topping

  • Pretzel salt, kosher salt, or flaky sea salt, for topping

Instructions

  • In the bowl of a stand mixer or a large mixing bowl, whisk together the warm water, sugar and active dry yeast. Let it sit for 5–10 minutes until frothy.
  • Add the melted butter, salt, and sourdough discard. Stir to combine. Add 4 cups of flour, mixing with a wooden spoon or dough hook attachment on low speed.
  • Knead on medium-low speed in the mixer for 5-8 minutes, or knead by hand on a lightly floured surface. If you’re using a mixer and the dough still feels too sticky after 5 minutes, add flour 1 tablespoon at a time until it comes together. If you’re kneading by hand and the dough becomes difficult to work with, sprinkle in flour 1 teaspoon at a time to help manage stickiness. If your dough is too dry add 1 tsp of water at a time. The dough should feel soft, smooth, and slightly tacky, when you press it with your finger, it should gently bounce back.
  • Transfer the dough to a greased large bowl, cover with plastic wrap or a clean kitchen towel, and let it rise in a warm place for 1 hour, or until doubled in size.
  • Punch down the dough and turn it out onto a lightly floured surface. Divide the dough into 12 equal pieces. Roll each piece into a smooth, tight ball by tucking the edges under and sealing the bottom. Gently press down on each bun to slightly flatten, this helps them spread just a bit for that classic pretzel bun shape. 
  • Preheat your oven to 400°F (204°C). Line a baking sheet with parchment paper. Set it aside for now.
  • In a large pot, bring 8 cups of water to a boil. Slowly stir in the baking soda. Working in batches, gently lower the buns into the water with a slotted spoon for 20–30 seconds each. Place them on a parchment-lined baking sheet.
  • Use a sharp knife or razor blade to score the tops. Sprinkle generously with pretzel salt or flaky sea salt.
  • Bake at 400°F (204°C) for 20 - 22 minutes, or until deeply golden brown.
  • Let cool on a wire rack for a few minutes. Serve warm or store in an airtight container at room temperature for up to 3 days.

Notes

  • Measuring flour: For best results, use a kitchen scale. Too much flour can make your dough stiff and dry. If you do not have a kitchen scale then use the spoon and level method.
  • Sourdough discard: You can use fed or unfed sourdough discard here. Discard that's only a few days old works best to avoid too much tang.
  • Melted Butter: You can brush the tops with melted butter right before baking if you’d like even more browning and a richer flavor. It’s totally optional but definitely delicious.
  • Make ahead: Baked buns can be frozen in a zip-top bag for up to 2 months. Reheat in the oven until warm.
  • Don’t skip the baking soda bath! It’s what gives that classic chewy crust and deep pretzel flavor.
  • Want soft sourdough pretzels instead? Use this same dough to make sourdough discard pretzel bites or twist into traditional shaped pretzels.
