How to make an egg wash

Ingredients for egg wash: 1 egg and 1 teaspoon of water.
To make an egg wash, lightly beat 1 egg in a small bowl with a fork. Mix thoroughly with 1 teaspoon of water.
Why make an egg wash? Egg wash adds shine and golden color to the pastry. It’s optional to use egg wash.
Why mix the egg with water? Mixing the lightly beaten egg with a small amount of water will result in a lighter golden color once applied to the pastry surface. Using just the egg will result in a darker color.

How to make chicken puff pastry

1) First, make the chicken and spinach filling. Heat 1 tablespoon of olive oil in a medium skillet, add 1/2 pound of chicken. Sprinkle with a pinch of salt and 1/2 teaspoon of paprika. Cook for about 5-10 minutes until the chicken is cooked through. Shred the chicken.

2) Add 6 oz spinach to the same skillet.

3) Cook, constantly stirring until the spinach wilts, about 3 minutes. Remove from heat.

4) Add 1/2 cup of shredded Parmesan cheese and combine with the chicken and spinach.

5) Next, assemble chicken puff pastry. Line a large baking sheet with parchment paper. Cut each puff pastry sheet into 4 rectangles. Place rectangles on the parchment paper lined sheet.

6) Place chicken and spinach filling on one half of each rectangle. Make sure to not overfill. You might have leftover filling.

7) Fold the other half of each rectangle over the filling to close. Pinch the edges to seal. You can quickly dip your fingers in a glass of water to help seal the edges.

8) Brush with egg wash (OPTIONAL).

9) Bake for 20 minutes until the puff pastry is golden brown.
