Turkish Spiral Spinach Borek: Flaky Golden Layers Step-by-step instructions

Before you start

Before starting, gather all ingredients and equipment. Wash the spinach thoroughly and chop it coarsely. Dice the onion into small, even pieces. Crumble the feta into a bowl. Prepare the liquid wash by whisking together the milk, yogurt, olive oil, and egg in a small bowl.

Have a round baking tray ready — a 10-inch metal or ceramic dish works well. If using phyllo dough instead of yufka, keep it covered with a damp towel to prevent it from drying out. Heat the oven to 375°F (190°C) before you begin assembling, so it is ready when the borek is.

Instructions

Prepare the Filling and Wash

1. 1Make the Spinach Filling
   In a large bowl, combine the chopped spinach, diced onion, crumbled feta, black pepper, and pul biber. Use your hands to massage the mixture for 2 to 3 minutes, until the spinach wilts and reduces in volume and everything is evenly distributed.
   Look for The spinach should be dark, glossy, and reduced by about half, with the feta evenly crumbled through.
   Tip Massaging the spinach helps it release moisture so the borek stays crisp, not soggy.
2. 2Prepare the Liquid Wash
   In a small bowl, whisk together the milk, yogurt, olive oil, and the egg until smooth and fully combined. Set aside.
   Look for The wash should be pale yellow and completely smooth, with no streaks of egg.
   Tip Whisk thoroughly so the egg is fully incorporated; this helps the layers blister and crisp.

The spinach should be dark, glossy, and reduced in volume, with the feta and onion evenly distributed. The liquid wash should be smooth and pale yellow. The mixture should hold together when pressed, and the wash should have no visible streaks of egg. This is the foundation for the rest of the borek, so take time to ensure everything is well combined and seasoned.

Assemble and Coil

3. 3Roll and Fill the Yufka
   Lay one yufka sheet on a clean work surface. Brush the entire surface with the liquid wash. Spoon a thick line of the spinach filling along one edge of the sheet, then roll the yufka tightly around the filling into a long, slender cylinder. Repeat with the remaining sheets and filling.
   Look for Each cylinder should be snug and uniform, about 1 1/2 inches in diameter.
   Tip Don't overfill; a thick line about 2 inches wide works best for even rolling.
4. 4Coil into a Spiral
   Lightly brush the bottom and sides of a round baking tray with the liquid wash. Starting at the center, coil one filled cylinder into a tight spiral, then continue with the remaining cylinders, attaching each end to the previous one to form one continuous snail shape. Tuck the final end underneath.
   Look for The spiral should be snug and even, filling the tray completely.
   Tip If the dough tears, just press it together; the wash will seal it during baking.
5. 5Brush and Top with Seeds
   Brush the top of the spiral generously with the remaining liquid wash. Sprinkle evenly with sesame seeds and nigella seeds.
   Look for The surface should be glossy and completely covered with the wash and seeds.
   Tip Use a light hand with the seeds; they should accent, not overwhelm.

The filled cylinders should be tight and uniform, about 1 1/2 inches in diameter. When coiled, the spiral should fill the tray completely with no large gaps.

The top should be glossy from the wash and speckled with sesame and nigella seeds. The spiral should look neat and inviting, with the layers clearly visible. If any tears occur, press them together — the wash will seal them during baking.

Bake to Golden Perfection

6. 6Bake the Borek
   Heat the oven to 375°F (190°C). Bake the borek for 35 minutes, until the top is deeply golden and puffed, and the layers are crisp and shatter when pressed. The internal temperature of the egg in the wash should reach 160°F (71°C) to ensure it is fully set.
   Look for The crust should be amber-brown and sound hollow when tapped.

   Tip If the top browns too quickly, cover loosely with foil for the last 10 minutes.
7. 7Rest and Serve
   Remove the borek from the oven and let it rest on a wire rack for at least 10 minutes before slicing. This allows the layers to set and makes cutting easier. Serve warm, tearing or slicing into wedges.
   Look for The borek should be firm enough to slice cleanly without crumbling.
   Tip Letting it rest keeps the filling from sliding out when you cut.

The borek should be deeply golden brown, with puffed layers and a crisp, crackling crust. The aroma of toasted sesame and baked pastry fills the kitchen. The top should feel firm and sound hollow when tapped. The internal temperature of the egg wash should reach 160°F (71°C). Let it rest for 10 minutes before slicing so the layers set and the filling holds together.

Common mistakes

One common mistake is overfilling the yufka, which makes rolling difficult and can cause the borek to burst open during baking. Keep the filling line about 2 inches wide and roll snugly but not too tight.

Another error is skipping the massage step for the spinach; if the spinach is not wilted, it releases moisture into the pastry and creates a soggy bottom. Also, be sure to brush the yufka thoroughly with the wash — a dry spot will not puff or crisp. Finally, do not rush the baking; underbaked borek will be pale and doughy instead of golden and flaky.

How to tell it’s done

The borek is done when the top is deeply golden brown, the edges are crisp, and the pastry sounds hollow when tapped. The internal temperature of the egg in the wash should read 160°F (71°C) on an instant-read thermometer inserted into the thickest part of the pastry.

The layers should be visibly puffed and shatteringly crisp, with no raw or doughy spots. If the top browns too quickly, cover loosely with foil and continue baking until the center is fully cooked. Let it rest for 10 minutes before slicing to allow the filling to set.
