Gather all ingredients.

Combine warm water and yeast in a large bowl. Let stand until foamy, about 5 minutes.

Blend egg whites and cottage cheese in a blender or food processor until smooth.

Add the cottage cheese mixture to the yeast mixture and whisk to combine.

Stir flour and salt into the wet mixture until combined; the dough will be sticky.

Knead the dough on a lightly floured surface for around 5 minutes until smooth and slightly tacky.

Shape dough into a ball and place in a lightly greased bowl. Cover and let rise until doubled in size, about 1 hour.

Line a 9x5-inch loaf pan with parchment paper.

Punch down the dough and shape into a loaf. Place it in the prepared pan and let rise for about 30 minutes.

Preheat the oven to 400°F (200°C) and score the loaf lengthwise with a sharp knife.

Bake the bread for 40–45 minutes, covering loosely with foil in the last 10–15 minutes to prevent overbrowning.
