Remove the chilled dough from the refrigerator. Cut the dough in half - taking time to enjoy the cross section that shows all those layers of buttery goodness that you just rolled out!
Roll each section into a long rectangular shape, approximately 10x22in. Using a pizza cutter, cut off any rough edges.
To shape the croissants, cut the rectangle in thirds across the short sides. Then using the pizza cutter, cut those rectangles into triangles by making 1 diagonal cut on each smaller rectangle, resulting in 2 triangles. Cut a small 1/2" notch on the short side of each triangle. (This helps the croissant to shape better.)
Roll from the long edge towards the small point of the triangle. Curve the ends inward to form the crescent, pinching the ends together if you can to encourage the shape to stay. Place on a parchment lined baking sheet to rise.
Proof for at least two hours in a warm place or at least room temperature. It's recommended to proof for about four hours to get a lighter texture.
Whisk an egg with a dash of water and brush on the unbaked croissants.
Preheat the oven to 375 degrees and bake for 19-22 minutes or until golden brown. Croissants should be flaky and a little crunchy on the outside. Serve warm & enjoy!
