Creating the perfect bagel is a labor of love that rewards patience. The magic happens during the overnight rest in the refrigerator, where the sourdough cultures work slowly to develop a robust profile and a superior crumb. This traditional process, combined with a quick boil in malt-infused water, ensures that classic, glossy exterior and dense interior that characterizes a true artisanal bagel.

  • 100 g active sourdough starter (100% hydration)
  • 400 g bread flour
  • 50 g whole wheat flour
  • 10 g sea salt
  • 25 g granulated sugar
  • 240 ml lukewarm water
  • 1 large yellow onion, finely chopped
  • 1 tbsp olive oil or unsalted butter
  • 1/2 tsp sea salt
  • 2 L water
  • 1 tbsp barley malt syrup or honey
  • 1 tsp baking soda

Instructions

Prepare the onions
In a skillet, heat olive oil or butter over medium heat. Add onions and 1/2 tsp salt. Sauté for 8–10 minutes until soft and golden. Set aside to cool.
Make the dough
In a large bowl, mix sourdough starter, bread flour, whole wheat flour, salt, sugar, and lukewarm water until a shaggy dough forms.
Knead
Knead for 8–10 minutes until smooth and elastic. Cover and let rest for 4 hours at room temperature, performing two stretch-and-folds during the first 2 hours (every 30 minutes).
Bulk ferment
Cover and refrigerate overnight (8–12 hours) for best flavor.
Shape bagels
The next day, divide dough into 8 equal pieces. Shape each into a ball, then poke a hole in the center and stretch to form a bagel shape (about 2 inches diameter hole).
Proof
Place shaped bagels on a parchment-lined baking sheet, cover, and let rise for 1–2 hours at room temperature until slightly puffy.
Boil bagels
Preheat oven to 220°C (425°F). Bring water, barley malt syrup (or honey), and baking soda to a boil in a large pot. Boil bagels 1–2 at a time, 1 minute per side. Remove with a slotted spoon and return to baking sheet.
Top and bake
While bagels are still damp, press sautéed onions onto the tops. Bake 20–25 minutes until golden brown and cooked through.
Cool
Transfer to a wire rack to cool before slicing.

Zusatztipps für die Zubereitung

For the best results, use high-quality bread flour. This provides the necessary protein content for the characteristic chew and rise of a traditional bagel. Ensure your onions are completely cooled before pressing them onto the damp dough to ensure they adhere properly during the bake.

Varianten und Anpassungen

You can easily customize these bagels by adding poppy seeds or sesame seeds along with the sautéed onions for extra texture. If barley malt syrup is unavailable, honey serves as an excellent substitute in the boiling water to help achieve a golden, slightly sweet crust.

Serviervorschläge

These savory bagels are perfect for breakfast when paired with a thick schmear of cream cheese. They also serve as an exceptional base for sandwiches, particularly when filled with smoked salmon, eggs, or fresh greens.

How to Make It

Step 01

Prepare the onion topping: Heat olive oil or butter in a skillet over medium heat. Add chopped onion and sea salt. Sauté for 8 to 10 minutes until soft and golden brown. Transfer to a plate and allow to cool completely.

Step 02

Combine dough ingredients: In a large mixing bowl, combine sourdough starter, bread flour, whole wheat flour, sea salt, granulated sugar, and lukewarm water. Mix until a shaggy dough forms with no dry flour remaining.

Step 03

Knead and initial rest: Knead dough for 8 to 10 minutes until smooth and elastic. Cover the bowl and rest at room temperature for 4 hours. Perform two stretch-and-fold sequences during the first 2 hours, repeating every 30 minutes.

Step 04

Cold fermentation: Cover dough and refrigerate overnight for 8 to 12 hours to develop optimal flavor and workability.

Step 05

Shape bagels: Divide chilled dough into 8 equal pieces. Roll each piece into a ball, then pierce the center with your thumb and gently stretch to form a bagel shape with approximately 2-inch diameter hole. Ensure even thickness throughout.

Step 06

Final proof: Place shaped bagels on a parchment-lined baking sheet. Cover and allow to rise at room temperature for 1 to 2 hours until slightly puffy but not fully doubled.

Step 07

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 1 to 2 at a time, cooking 1 minute per side. Remove with a slotted spoon and return to baking sheet.

Step 08

Top and bake: While bagels remain damp from boiling, press cooled sautéed onions firmly onto the top surface of each bagel. Bake for 20 to 25 minutes until golden brown and fully cooked through.
