Making these Ham and Cheese Puff Pastry Twists is incredibly easy and fun. Even beginner bakers can achieve perfect results by following these simple, step-by-step instructions. Get ready to create a batch of delicious, flaky twists in no time!

1. Preheat Oven and Prepare Baking Sheet: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Preheating the oven is crucial for ensuring the puff pastry rises properly and bakes to a golden brown. Parchment paper prevents sticking and makes cleanup a breeze.
2. Prepare Puff Pastry Sheets: Lightly flour a clean work surface. Unfold one sheet of thawed puff pastry onto the floured surface. If your puff pastry comes in a roll, gently unroll it. A lightly floured surface prevents the pastry from sticking and makes it easier to handle.
3. Spread Mustard (Optional): If using Dijon mustard, spread a thin layer evenly over the surface of the puff pastry sheet, leaving a small border around the edges. Don’t overdo it with the mustard, as you only want a subtle flavor enhancement.
4. Layer Ham and Cheese: Arrange half of the thinly sliced ham evenly over the puff pastry sheet on top of the mustard (if using). Make sure the ham is distributed evenly so that each twist gets a good amount. Sprinkle half of the shredded cheese evenly over the ham. Again, ensure even distribution for consistent flavor and texture in every twist.
5. Top with Second Puff Pastry Sheet: Carefully place the second sheet of puff pastry on top of the ham and cheese layer, aligning the edges as closely as possible with the bottom sheet. Gently press down on the top sheet to seal it lightly to the bottom sheet, helping the layers stick together.
6. Slice into Strips: Using a sharp knife or a pizza cutter, cut the layered puff pastry sheet lengthwise into strips, about ¾ inch to 1 inch wide. The width of the strips will determine the size of your twists. Aim for consistent widths for even baking.
7. Twist Each Strip: Take one strip at a time and twist it several times to create a spiral shape. Hold each end of the strip and twist in opposite directions. Don’t be afraid to twist firmly, but gently enough to avoid tearing the pastry. The twisting is what gives these snacks their signature look and creates layers that will become wonderfully flaky.
8. Place Twists on Baking Sheet: Carefully place each twisted strip onto the prepared baking sheet, leaving some space between them. Spacing them out allows for proper air circulation and even baking, ensuring they become crispy and golden all around.
9. Brush with Egg Wash: In a small bowl, whisk the egg. Brush each twist generously with the beaten egg wash. Ensure you cover all surfaces, including the sides, to get that beautiful golden-brown color.
10. Sprinkle with Seeds (Optional): If desired, sprinkle sesame seeds or poppy seeds over the egg-washed twists. Press them lightly to help them adhere to the egg wash.
11. Bake: Bake in the preheated oven for 15-20 minutes, or until the twists are golden brown and puffed up. Baking times can vary slightly depending on your oven. Keep an eye on them and adjust the baking time if needed. The twists are done when they are beautifully golden and the pastry is cooked through.
12. Cool Slightly and Serve: Remove the baking sheet from the oven and let the Ham and Cheese Puff Pastry Twists cool slightly on the baking sheet for a few minutes before serving. They are best served warm when the pastry is at its flakiest and the cheese is still melty and delicious. Serve immediately and enjoy!
