3. Step-by-Step Cooking Instructions & Crisping Secrets
Now, let’s talk about the cooking process. To achieve the perfect balance of crispy pastry and fluffy interior, I like to preheat the oven to 400°F (200°C).
I then brush the edges of the pastry with a little water, which helps the pastry seal tightly and prevents it from opening up during baking.
After that, it’s a simple matter of baking the bundles for 10 minutes or until golden brown.

Step-by-Step Culinary Timeline
1. Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Cut the puff pastry into 4 equal squares. Place 1/4 cup of asparagus in the center of each square, leaving a 1-inch border around the asparagus.
3. Sprinkle 1/2 tbsp of Parmesan cheese, 1/2 tbsp of chopped Parma ham, and 1/2 oz of shredded mozzarella cheese over the asparagus.
4. Brush the edges of the pastry with a little water, then fold the pastry into a triangle, pressing gently to seal.
5. Place the bundles on the prepared baking sheet, leaving about 1 inch of space between each bundle.
6. Bake for 10 minutes or until golden brown. Serve hot and enjoy!
Meal-Prep Storage & Crispy Air-Fryer Reheating Guide
• Cool Before Sealing: Let cooked portions cool for 10 minutes before sealing in glass containers so steam never softens the crust (keeps 4 days in the fridge).
• Sauce on the Side: Store dips, drizzles, and fresh herbs separately until right before serving.
• 3-Minute Crispy Reheat: Reheat in a 380°F (193°C) air fryer or dry cast-iron skillet for 3–4 minutes to restore shatteringly crisp edges.
