Ingredients
- Pork mince: One kilogram ensures juicy and flavorful filling Choose high quality mince with a good fat ratio for best texture
- Salt reduced French onion soup mix: Adds savory depth and classic caramelized onion notes Look for a trusted brand with plenty of dried onion flakes
- Tomato ketchup: Adds a little sweetness and helps keep the filling moist Select a rich tangy ketchup for the best base
- Worcestershire sauce: Lends that punchy umami tang I always use a dash extra for grown-up flavor
- Dijon mustard: Gives mild heat and creaminess plus helps balance the richness Use a smooth French Dijon for silky texture
- Woolworths Puff Pastry Sheets: Buttery and crisp when baked Defrost fully in the fridge so it rolls and seals evenly
- Egg and milk for brushing: Create that glossy bakery finish on top of the pastry Crack your egg fresh for the most vibrant color
- Fresh pepper: A generous grind wakes up the sausage mixture
Step-by-Step Instructions
- Mix the Filling:
- In a large bowl thoroughly combine your pork mince French onion soup mix tomato ketchup Worcestershire sauce and Dijon mustard Season generously with black pepper Mix well with clean hands until everything is evenly blended and the texture feels sticky
- Prepare the Pastry:
- On a cool bench top cut each sheet of puff pastry in half Defrost completely but work quickly so the pastry does not become sticky or hard to roll
- Shape the Logs:
- Take a portion of sausage mixture and shape it into a log running down the long edge of each pastry half The filling should reach from one end to the other but leave space on either side for sealing
- Seal and Slice:
- In a small bowl whisk together the egg and milk Brush a line of this mixture along the pastry edge next to the sausage Carefully roll the pastry up and press the edge to seal Brush the top of each roll with egg mixture for shine
- Cut and Arrange:
- Using a small serrated knife slice each long roll into bite-sized pieces Place each piece seam side down on a tray lined with baking paper This keeps them from unraveling as they puff
- Bake to Golden Perfection:
- Preheat your oven to two hundred degrees Celsius Bake the rolls for twenty to twenty five minutes until the pastry is golden and the filling is cooked through Let cool slightly before serving as the inside will be piping hot

Woolworths French onion soup mix gives the richest oniony flavor but I once tried a fancy organic blend and the result just was not the same The classic soup mix really makes the taste just right My kids always argue over who gets the crispiest end piece a tradition during Sunday game days
