Ingredients

Meat Mixture

  • 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
  • Fresh herbs (thyme, rosemary, parsley), chopped, divided
  • Chili flakes (optional, to taste)

Pastry

  • 2 sheets puff pastry, thawed if frozen
  • Cheese (cheddar or mozzarella), grated or sliced

Egg Wash

  • 1 egg
  • 1 tbsp milk

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C) and line a baking tray with parchment paper to prevent sticking and ensure even baking.
  2. Prepare Meat Mixture: In a mixing bowl, combine the pork mince with the French onion soup mix or the alternative sautéed onions with onion powder. Add ketchup, Worcestershire sauce, Dijon mustard, freshly cracked black pepper, half of the chopped fresh herbs, and chili flakes if using. Mix thoroughly until evenly combined.
  3. Assemble Sausage Rolls: On a lightly floured surface, unroll one sheet of puff pastry. Spoon the meat mixture into a long log shape along one long edge of the pastry, leaving a 1/2-inch border free. Place a strip or layer of your chosen cheese on top of the meat filling.
  4. Roll and Seal: Carefully roll the pastry over the filling, pressing gently to enclose the meat and cheese. Pinch the seam tightly to seal. Repeat this process with the second sheet of puff pastry and remaining filling.
  5. Slice Rolls: Cut each rolled log into 6 to 8 pieces depending on desired size. Place each piece seam-side down on the prepared baking tray to prevent unrolling while baking.
  6. Apply Egg Wash: In a small bowl, whisk together the egg and milk. Brush this mixture generously over the tops and sides of each sausage roll to create a golden, glossy finish during baking.
  7. Bake: Place the tray in the preheated oven and bake for 20 to 25 minutes, or until the pastry is golden brown and cooked through, and the filling is hot and fully cooked.

Notes

  • You can substitute the pork mince with other ground meat such as beef or lamb if preferred.
  • The French onion soup mix provides rich flavor but using sautéed onions with onion powder is a great homemade alternative.
  • Adjust chili flakes according to your preferred spice level or omit for a milder taste.
  • Make sure puff pastry is fully thawed before using to prevent tearing.
  • Serve warm, ideal with mustard or a dipping sauce of choice.
