In a large mixing bowl, whisk together the flour, yeast, salt, and sugar to evenly distribute the dry ingredients.
Add the Greek yogurt, softened butter, and lukewarm milk to the bowl. Mix until the ingredients come together into a cohesive dough. No kneading is required at this stage—just ensure everything is well combined.
Cover the bowl with a clean kitchen towel and let the dough rest at room temperature for 20 minutes.
After the resting period, knead the dough by hand for 3-4 minutes until it becomes smooth and pliable.
Form the dough into a smooth ball. If desired, brush the surface with a thin layer of oil to prevent drying out.
Place the dough ball in a clean bowl, cover it with a towel, and let it rise in a warm place for 45 minutes to 1 hour, or until it doubles in size.
Lightly flour your work surface and transfer the dough. Divide it into 10 equal portions, approximately 3 ounces (90 g) each.
Using a rolling pin, flatten each portion into a long rectangular shape.
Fold the bottom edge of the dough upward and press gently with your fingers.
Fold the left and right edges inward, then fold the bottom edge upward again.
Repeat the folding process until you have a neat bun. Pinch the bottom seam tightly to seal the bun and maintain its shape.
Arrange the shaped buns on a baking sheet lined with parchment paper. Cover them with a towel and let them rise for another 45 minutes to 1 hour.
Preheat your oven to 350°F (180°C). Lightly dust the buns with flour and score the tops with a sharp knife or razor blade for a decorative finish.
Bake the buns for 20-25 minutes, or until they turn golden brown and fill your kitchen with a delicious aroma.
After baking, cover the buns with a kitchen towel for a softer crust, or leave them uncovered for a crispier texture. Serve warm or at room temperature with butter, jam, or cream cheese. Enjoy!
