Ingredients

Pork mince (1 lb / 450g): Ground pork provides juicy, tender meat base for the flavorful sausage filling.
French onion soup mix (1 packet): Adds signature savory, caramelized onion flavor without extra prep time.
Tomato ketchup (1 tbsp): Introduces a slight sweetness and tang to balance the savory notes.
Worcestershire sauce (1 tsp): Deepens umami with its rich, tangy flavor.
Dijon mustard (1 tsp): Brings a subtle spicy kick and complexity to the filling.
Freshly cracked black pepper: Season to taste for a mild heat and enhanced aroma.
Puff pastry sheets (2 sheets): Provides light, flaky, buttery wrapping essential for texture contrast.
Egg (1): Used in egg wash to achieve a beautiful golden, glossy finish.
Milk (1 tbsp): Combined with egg to make a smooth egg wash that enhances browning.
Cheese (optional): Cheddar or mozzarella can be added for gooey, melty richness inside.
Fresh herbs (optional): Thyme, rosemary, or parsley offer fresh earthy highlights.
Chili flakes (optional): Add for subtle heat and a spicy note if desired.

Instructions

Preheat and Prepare Baking Tray: Set your oven to 200°C (392°F) and line a baking tray with parchment paper. This ensures even baking and prevents sticking for easy cleanup.
Make the Savory Filling: In a large mixing bowl, combine pork mince with French onion soup mix, ketchup, Worcestershire sauce, Dijon mustard, and freshly cracked black pepper. Mix thoroughly until the ingredients are evenly incorporated to build depth of flavor in every bite.
Cut and Fill the Pastry: Roll out puff pastry sheets and slice each one in half lengthwise. Place an even portion of the sausage filling along one edge of each pastry strip to prepare for rolling. This helps achieve uniform sausage rolls that cook evenly.
Roll and Seal: Gently roll the pastry over the filling, enclosing it tightly. Seal edges carefully with a bit of water or egg wash to prevent the filling from leaking during baking.
Brush with Egg Wash: Beat together the egg and milk, then brush generously over the tops of the rolls. This step creates the signature golden, shiny finish that makes these sausage rolls visually appealing.
Bake Until Golden: Arrange the sausage rolls on the prepared tray and bake for 20–25 minutes. Cook until the pastry is puffed and golden brown and the filling is cooked through for optimal flavor and texture.
Cool and Serve Warm: Allow the rolls to cool slightly before slicing to retain juiciness. Serve warm as delicious standalone snacks or with your favorite dips and sides.

You Must Know

Use thawed puff pastry for best rolling and baking results.
Ensure sausage filling is evenly distributed to avoid uneven cooking.
For spice lovers, adding chili flakes or hot sauce elevates the flavor.
Not recommended to microwave reheating to maintain pastry crispness; use oven instead.

Storage Tips

Store leftover sausage rolls in an airtight container in the refrigerator for up to 3 days. To freeze, freeze unbaked rolls on a tray before transferring to a freezer bag; bake from frozen for fresh results.

Serving Suggestions

These savory rolls pair wonderfully with tangy mustard, spicy ketchup, or creamy ranch dip. Serve with a fresh green salad or crispy fries for a satisfying party platter or snack.

Professional Tips

Pour excess fat from sausage filling before filling pastry to avoid sogginess.
Use a sharp knife or pizza cutter for clean, even slices post baking.
Let rolls rest briefly after baking to allow filling to set for safer serving.
