These puff pastry twists with Dijon mustard are a quick appetizer made with store-bought puff pastry. Ready in 30 minutes and perfect for entertaining.
Prep. Preheat the oven to 400˚F. Line two baking sheets with parchment paper and set aside.
Roll out the dough. On a lightly floured surface, roll one sheet of puff pastry into a 12×16-inch rectangle.
Add mustard. Spread 1/4 cup of the mustard over the lower half of the dough.
Fold and cut. Fold the top portion of the dough over the bottom, covering up the mustard. Using a sharp knife or a pizza cutter, cut the pastry from top to bottom into strips about 1-inch wide. Then, cut the strips in half, crosswise.
Chill. Carefully transfer the puff pastry twists to the baking sheets, then place them in the fridge; repeat the process with the next batch.
Make the egg wash. Whisk the egg with a splash of water.
Brush. Remove the puff pastry twists from the fridge. Brush the tops of all the strips with the egg wash and sprinkle with sesame seeds or poppy seeds.
Bake. Transfer the baking sheets to the oven and bake for 8 minutes. Rotate the sheets from front to back and top to bottom and bake for an additional 7 to 8 minutes, or until the strips are puffed up and golden brown.
Serve. Remove from oven and let rest for 2 minutes before serving.
