Preheat your oven to 375°F (190°C).
In a mixing bowl, combine the flour, baking powder, and kosher salt. Stir until well mixed.
Add the strained cottage cheese and the beaten egg white to the dry mixture. Stir until the dough starts to come together.
Lightly flour your countertop and turn the dough out. Knead it gently for about 1-2 minutes until smooth.
Divide the dough into four equal pieces, roll each into a ball, and shape into bagels.
Sprinkle your desired toppings on top of each bagel.
Place the bagels on a baking sheet lined with parchment paper. Bake for 20-25 minutes until golden brown.
Allow to cool on a wire rack before slicing and serving.
