Step 1

Preheat the oven to 425°F.

Step 2

Unroll the puff pastry sheet onto a piece of parchment paper.

Step 3

Gently roll it out into a large rectangle using a rolling pin. Sprinkle a little flour on top if the rolling pin sticks to the dough.

Step 4

Spread pizza sauce down the center of the pastry, leaving space on the sides.

Step 5

Layer the mozzarella cheese over the sauce.

Step 6

Add the sliced pepperoni on top.

Step 7

Using a pizza cutter or sharp knife, cut the pastry into diagonal strips along both sides of the toppings.

Step 8

Fold the strips over the center, alternating sides to form a braid.

Step 9

Brush the braid with the beaten egg, then sprinkle extra Parmesan cheese and Italian seasoning on top.

Step 10

Carefully lift the parchment paper and transfer it to a baking tray.

Step 11

Bake in the preheated oven for 20-25 minutes, or until the puff pastry is golden brown and flaky.

Step 12

Cut into slices and serve warm with extra pizza sauce on the side.
