Equipment

  • Medium bowl
  • Whisk
  • Spatula
  • Baking Sheet
  • Parchment Paper
  • Large pot (optional for boiling)

Ingredients
 

  • 300 grams all-purpose flour
  • 5 grams baking powder
  • 6 grams salt
  • 5 grams sugar
  • 200 grams sourdough discard
  • 240 grams full fat Greek yogurt
  • 10 grams olive oil

For the egg wash:

  • 1 egg & a splash of water
  • seeds for topping

Instructions
 

Mix the Dough

  • In a medium bowl, whisk together the all-purpose flour, baking powder, salt, and sugar until well combined.
  • In a separate bowl, whisk the sourdough discard with the full fat Greek yogurt until smooth, then stir in the olive oil.
  • Pour the wet mixture into the dry ingredients and fold with a spatula until a shaggy dough forms. If needed, add water 1 teaspoon at a time until the dough comes together.

Knead and Rest

  • Turn the dough onto a clean surface and knead for 3–5 minutes, until it becomes smoother and more elastic.
  • Cover the dough and let it rest for 15-30 minutes to relax the gluten.

Shape the Bagels

  • Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
  • Divide the rested dough into 8 equal pieces (about 95-100 grams each). Roll each piece into a smooth ball, place on the prepared pan, and let them rest for another 10 minutes.
  • Press your thumb into the center of each dough ball to create an opening. Gently stretch the dough with your fingers to form a ring with a hole about 1 inch across.

Boil, Top, and Bake

  • Optional: For a chewier crust, bring a large pot of water to a boil. Add 1 tablespoon of baking soda and 1 tablespoon of honey. Boil 2-3 bagels at a time for 30-60 seconds per side, then return them to the baking sheet.
  • In a small bowl, whisk the egg with a splash of water. Brush this egg wash over the tops and sides of each bagel, then sprinkle generously with your desired seeds or toppings.
  • Bake for 20–25 minutes, or until the bagels are golden brown and sound hollow when tapped.
  • Let the bagels cool on a wire rack for at least 15-20 minutes before slicing to allow the crumb to set properly.

Notes

Flour Choice: For an extra chewy, authentic bagel texture, substitute bread flour for the all-purpose flour.
Boiling Tip: The optional water bath with baking soda and honey is highly recommended. It gelatinizes the crust, resulting in the classic glossy finish and chewy bite of a traditional bagel.
Dough Handling: If the dough feels too sticky to handle, lightly oil your hands rather than adding excess flour, which can make the bagels dry.
Storage: Keep cooled bagels in a paper bag at room temperature for up to 2 days. For longer storage, slice them before freezing in a freezer-safe bag for up to 3 months. You can toast them directly from frozen.
