Description

Delicious and flavorful sourdough onion bagels, perfect for breakfast or a snack.


Ingredients

Scale
  • 3.5 oz active sourdough starter, 100% hydration
  • 14.1 oz bread flour
  • 1.8 oz whole wheat flour
  • 0.35 oz sea salt
  • 0.9 oz granulated sugar
  • 8.1 fl oz lukewarm water
  • 1 large yellow onion, finely chopped
  • 1 tablespoon olive oil or unsalted butter
  • 0.25 teaspoon sea salt
  • 67.6 fl oz water
  • 1 tablespoon barley malt syrup or honey
  • 1 teaspoon baking soda

Instructions

  1. Prepare the onion topping: Heat olive oil or butter in a skillet over medium heat. Add chopped onions and 0.25 teaspoon salt. Sauté for 8-10 minutes until softened and golden brown. Transfer to a plate and allow to cool completely.
  2. Mix the dough: In a large mixing bowl, combine sourdough starter, bread flour, whole wheat flour, salt, sugar, and lukewarm water. Stir until a shaggy dough forms with no dry flour visible.
  3. Knead and rest: Knead the dough for 8-10 minutes until smooth and elastic. Cover the bowl and rest at room temperature for 4 hours. Perform two stretch-and-folds during the first 2 hours, working every 30 minutes.
  4. Bulk fermentation: Cover the dough and refrigerate for 8-12 hours overnight. This extended fermentation develops the characteristic tangy sourdough flavor.
  5. Shape bagels: Divide chilled dough into 8 equal portions. Form each piece into a ball, then pierce the center and stretch to create a bagel shape with approximately 2-inch center hole.
  6. Final proof: Place shaped bagels on a parchment-lined baking sheet. Cover and allow to rise at room temperature for 1-2 hours until slightly puffy.
  7. Boil bagels: Preheat oven to 425°F. Bring water, barley malt syrup or honey, and baking soda to a rolling boil in a large pot. Boil bagels in batches of 1-2, allowing 1 minute per side. Remove with a slotted spoon and return to the baking sheet.
  8. Top and bake: While bagels are still damp, press sautéed onions firmly onto the top surface of each bagel. Bake for 20-25 minutes until deep golden brown and cooked through.
  9. Cool: Transfer bagels to a wire cooling rack. Allow to cool completely before slicing and serving.

Notes

  • For a richer flavor, you can caramelize the onions longer.
  • Ensure the sourdough starter is active before using it in the recipe.
  • Bagels can be sliced and frozen for longer storage.
