Step 1

Start by preheating your oven to 375F

Step 2

Mix together the warm water and yeast in a bowl and set aside for 2 minutes to proof

Step 3

In a bowl, add 1 cup of the flour (not all of it), the sugar, and the water and yeast mixture. Mix together well, then cover with plastic wrap and set aside for 10 minutes (you can move on to the filling at this point)

Step 4

After 10 minutes, the mixture will look a bit bubbly. Add to it the rest of the flour (1.5 cups), the olive oil, and the salt and mix well using your spoon to bring the dough together

Step 5

Then use your hands to knead the dough for 5-7 minutes and bring it together. It will be a soft dough and slightly sticky (which will give us that fluffy texture) so you can add the extra 2 tablespoons of flour as you knead it. Feel free to do this step in a stand mixer and a dough hook as well.

Step 6

Place the dough in an oiled bowl and cover. Allow it to rise for 45 minutes to 1 hour.

Step 7

Punch down the dough and shape into equal sized balls. I weighed out roughly 40g per dough ball using a kitchen scale, but you can eye this if you like. Cover the balls and allow them to proof for another 10-15 minutes before shaping

Step 8

Thaw out the frozen spinach in advance. If you're working last minute, feel free to use the microwave; place in a microwave safe bowl and thaw in 1 minute intervals. See notes if you're using fresh spinach.

Step 9

Meanwhile, cook the diced onions on a skillet using the olive oil on medium heat for 5-7 minutes, until they're soft and translucent

Step 10

Place the thawed spinach in a sieve over a bowl and squeeze out as much water as possible using a spoon or your hands. This step is really important to avoid a soggy fatayer that will open up in the oven!

Step 11

Place the squeezed spinach in the skillet with the onions and add the sumac, salt and pepper. Continue to cook the mixture for another 5 minutes to further dry it up from any moisture. Taste and adjust; if you like it more tart, add a squeeze of lemon

Step 12

Roll out the dough balls into a very thin circle. Place 1.5 tablespoons of the filling in the middle and fold together two sides, then bring up the third to form a triangle. Be sure to reference the photos in the post. Pinch the sides together really tightly and make sure the filling doesn't touch the edges to ensure a secure seal

Step 13

Mix together the grated mozzarella, crumbled feta, chopped parsley and nigella seeds well

Step 14

Roll out the dough balls into a long and thin oval. Place 1.5 tablespoons of the filling in the middle and fold over the top and bottom tips of the oval to form a "boat" shape. Be sure to reference the photos in the post.

Step 15

Place the fatayer gently on a floured baking sheet. You may choose to brush them with eggwash, but this is optional if you want a shinier surface. I personally skip this step

Step 16

Place the sheet pan in the oven on the bottom rack for 10-15 minutes, until you check the bottom and it is golden brown

Step 17

Move the pan to the middle rack and switch the oven to broil for 1-2 minutes but stay right beside it! The tops will brown to a light golden very quickly and that's when you can remove them

Step 18

Place them on a platter or a tray and immediately cover them with a towel to ensure they don't dry out and stay soft. Serve warm and enjoy!
