In a stand mixer fitted with a dough hook (or a large bowl), combine water, active sourdough starter, honey, and salt. Add the bread flour and mix until a smooth dough forms.
Bulk Fermentation
Cover and let the dough rise at room temperature until doubled in size. During this time, perform 2–3 sets of stretch and folds to strengthen the dough.
Cold Ferment
Refrigerate the dough for a few hours or overnight for deeper flavor and easier shaping.
Shape the Bagels
Divide the dough into 6 equal pieces (about 160g each). Roll each piece into a ball, then poke a hole through the center and gently stretch to form a ring.
Second Rise
Let the shaped bagels rise at room temperature until fluffy and slightly puffy, about 1–2 hours.
Boil
Bring a large pot of water to a boil. Boil each bagel for 1 minute per side. Remove with a slotted spoon and place on a lined baking sheet.
Egg Wash & Season
Brush the tops with whisked egg and sprinkle generously with everything bagel seasoning.
Bake
Bake at 425°F for 25 minutes, or until golden brown.
Cool
Cool completely on a wire rack before slicing.
Notes
Make sure your sourdough starter is active and bubbly before mixing the dough.
For extra chew, you can add 1 tablespoon of honey or baking soda to the boiling water.
Bagels freeze well — slice before freezing for easy toasting.
