Equipment

  • Baking tray
  • Parchment paper
  • Large mixing bowl
  • Spoon or spatula
  • Pastry brush
  • Knife or pizza cutter

Ingredients
  

Filling:

  • 1 lb (450g) pork mince (ground pork)
  • 1 packet French onion soup mix (or 1 cup sautéed onions + 1 tsp onion powder)
  • 1 tbsp tomato ketchup
  • 1 tsp Worcestershire sauce
  • 1 tsp Dijon mustard
  • Freshly cracked black pepper, to taste

Pastry & Finish:

  • 2 sheets puff pastry, thawed if frozen
  • 1 egg
  • 1 tbsp milk

Optional Extras:

  • Cheese (cheddar, mozzarella)
  • Fresh herbs (thyme, rosemary, parsley)
  • Chili flakes for spice

Instructions
 

  • Preheat Oven: Set oven to 200°C (392°F). Line a baking tray with parchment paper.
  • Prepare Filling: In a large bowl, combine pork mince, French onion soup mix, ketchup, Worcestershire sauce, Dijon mustard, and cracked black pepper. Mix until evenly incorporated.
  • Assemble Rolls: Roll out puff pastry sheets and cut in half lengthwise. Place a portion of filling along one edge of each sheet. Roll the pastry over the filling and seal the edges using water or egg wash.
  • Apply Egg Wash: Beat the egg with milk. Brush over the tops of the rolls for a golden, glossy finish.
  • Bake: Place rolls on the prepared tray and bake 20–25 minutes, or until golden brown and cooked through.
  • Cool & Serve: Allow rolls to rest for a few minutes before slicing. Serve warm with dips, sides, or enjoy as-is.

Notes

  • Storage: Keep in an airtight container in the fridge for up to 3 days.
  • Freezing: Freeze unbaked rolls on a tray, then transfer to a freezer bag; bake from frozen.
  • Reheating: Oven reheat preserves crispness; microwave may soften pastry.
  • Variations: Add cheese, fresh herbs, or chili flakes for custom flavors.
  • Vegetarian Option: Use mushrooms, lentils, and cheese in place of meat.
