Step 1: Prepare the Dough
In a large mixing bowl, whisk together the bread flour, rye flour, instant yeast, salt, and sugar.
Add warm water and vegetable oil, then mix until a rough dough forms.
Transfer the dough to a lightly floured surface and knead for about 8–10 minutes until smooth and elastic.
Place the dough in a greased bowl, cover with a damp towel, and let it rise in a warm place for 1–1.5 hours or until doubled in size.
Step 2: Shape the Bagels
Punch down the risen dough and divide it into 8 equal portions.
Roll each piece into a ball, then poke a hole through the center using your thumb.
Gently stretch and shape each piece into a bagel, ensuring an even thickness.
Place the shaped bagels on a parchment-lined baking sheet, cover, and let them rest for 20 minutes.
Step 3: Boil the Bagels
In a large pot, bring 8 cups of water to a boil. Add baking soda and molasses (or honey) to the water.
Carefully drop bagels into the boiling water, 2–3 at a time, and boil for 45 seconds per side.
Use a slotted spoon to remove the bagels and place them back on the lined baking sheet.
Step 4: Add Toppings and Bake
Preheat oven to 425°F (220°C).
Brush the boiled bagels with egg white and sprinkle generously with poppy seeds, sesame seeds, caraway seeds, onion flakes, and coarse salt.
Bake for 18–22 minutes, or until the bagels turn deep golden brown and sound hollow when tapped.
Transfer to a wire rack and let them cool before serving.
Step 5: Enjoy!
