Make The Filling 

Combine cheese and chopped parsley in a bowl and put it aside. Also, keep the melted butter in another bowl on the side.

Combine flour, milk and eggs in a large bowl. Knead it well either with your hands or in your stand mixer. Add little flour if necessary. It won’t be a soft dough. Now transfer the dough on the counter, roll it into a log and cut it into 10 balls. Cover them with a damp kitchen towel so that they don’t dry when you are rolling them out one by one. Dust the counter with a little flour each time you roll out a dough ball. Stack the phyllo sheets on the counter. Make sure you sprinkle a generous amount of flour between each so that they don’t stick. Brush a baking sheet with oil or use a cooking spray. Place an uncooked phyllo sheet in the baking sheet as the bottom of your water borek. Then cook the remaining phyllo sheets. Read on to learn how.

Fill a large pot with water, add in salt and olive oil. Bring it to a boil. Fill a large bowl with cold water and put it aside. With the help of a thin rolling pin, take the phyllo sheet to the pot and drop it into the simmering water. Keep it there for 2 minutes and take it out with a large slotted spoon. Transfer it into the cold water to stop cooking. Keep it there for a few seconds and then transfer it on a clean kitchen towel. Repeat the same steps for the remaining phyllo sheets. 

Remember the first phyllo sheet you place uncooked in the baking sheet? Brush the top of it with melted butter. Now place a cooked phyllo sheet on that first one. Brush it with melted butter too. Repeat with 3 more phyllo sheets. Spread the cheese mixture on the fifth phyllo sheet. Place the 6th phyllo sheet on it. Brush it with melted butter and repeat with the remaining sheets. 

Cut it into squares and serve.
