  • Ground pork (1 lb / 450g): The juicy, flavorful protein base. You can swap for beef or turkey if preferred.
  • French onion soup mix or sautĂ©ed onions + onion powder: Adds that signature aromatic sweetness. Freshly caramelized onions work beautifully for deeper flavor.
  • Tomato ketchup (1 tbsp): A subtle tang and moisture enhancer.
  • Worcestershire sauce (1 tsp): Brings umami depth and a slight tang.
  • Dijon mustard (1 tsp): Adds a gentle sharpness that lifts the filling.
  • Freshly cracked black pepper: For a mild spicy warmth.
  • Puff pastry (2 sheets): The golden, flaky exterior. Use good quality frozen pastry thawed overnight for the best texture.
  • Egg + milk for egg wash: Ensures a beautifully shiny and golden crust.
  • Cheese (cheddar or mozzarella): Melts wonderfully inside, adding creaminess and a bit of stretch.
  • Fresh herbs (thyme, rosemary, parsley): Brighten the savory profile with herbal notes.
  • Chili flakes (optional): For a gentle kick if you like things just a bit spicy.

Prep Before You Begin

Getting everything ready first makes all the difference. I recommend thawing your puff pastry in the fridge overnight so it’s pliable but still cool. Preheat your oven to 400°F (200°C) early on to ensure it’s fully hot by baking time—this helps the pastry puff up perfectly crisp. Also, set up your work surface with a light dusting of flour to avoid any sticking when rolling out the dough.

Tools & Setup

Here’s what you’ll want on hand so your French Onion Sausage Rolls Recipe comes together smoothly—plus optional extras that make the process even easier.

How to Make French Onion Sausage Rolls Recipe

  1. Preheat the oven to 400°F (200°C). Line a baking tray with parchment paper—it helps keep the bottoms golden, not burnt.
  2. Mix the filling by combining the pork mince with the French onion soup mix (or your sautéed onions and onion powder), ketchup, Worcestershire sauce, Dijon mustard, black pepper, half the fresh herbs, and chili flakes if you like a little heat. Stir until everything is evenly blended and aromatic. You’ll notice the rich scent developing even before baking.
  3. Prepare your pastry by lightly flouring your surface and unrolling one sheet of puff pastry. Spoon the meat mixture in a neat log along the long edge, leaving about half an inch from the border to make sealing easier.
  4. Add the cheese in a strip atop the meat log—this melts to a velvety blanket inside, giving each bite a creamy surprise.

    Expert Tips to Nail It

    Make sure not to overfill the pastry; leaving that border free helps you seal tightly without leaks. Chill the rolls briefly if your kitchen is warm—cold pastry seals and bakes better. When brushing the egg wash, be gentle to avoid sogginess but thorough enough for a shiny crust that bakes to a golden perfection.

  5. Roll the pastry tightly over the filling and pinch the seam closed to keep the sausage fillings snug. Repeat the process with the second sheet for two rolls.
  6. Slice into pieces, about 6 to 8 per roll, depending on your preferred size. Place them seam-side down on your lined tray for optimal shape retention and a crisp bottom.
  7. Prepare the egg wash by whisking together the egg and milk, then brush generously over each roll. This will give your sausage rolls that irresistible golden sheen and a lightly crisp crust.
  8. Bake in your preheated oven for 20 to 25 minutes. You’ll know they’re ready when the pastry is puffed up, beautifully golden, and you can see the filling cooked through without any pink spots.
  9. Cool briefly on a wire rack—this lets the steam escape so the pastry stays crisp and your fingers stay happy while you dive in.

  • Turn these into mini bites by using smaller pastry squares for party snacks or lunchboxes.

Storage, Freezing & Reheating

  • Store cooled sausage rolls in an airtight container for up to 3 days in the fridge.
  • Freeze unbaked rolls on a tray until firm, then transfer to a zip-lock bag and freeze for up to 2 months. Bake from frozen, adding a few extra minutes.
  • Reheat baked rolls in a 350°F (175°C) oven for 10 minutes to crisp them back up nicely.
  • For microwave reheating, cover lightly; expect softer pastry texture.

French Onion Sausage Rolls Recipe FAQs

  • Can I use store-bought French onion soup mix?
    I often do—it’s a handy shortcut that still delivers great flavor. If you prefer, caramelize fresh onions for a homemade touch.
  • What if my puff pastry tears?
    Don’t worry! Patch small tears with a little water and extra pastry—these imperfections won’t affect taste, just a little rustic charm.
  • Can I prepare French Onion Sausage Rolls Recipe ahead of time?
    Absolutely. You can shape the sausage rolls and refrigerate them before baking, or freeze unbaked rolls for later enjoyment.
  • How spicy are these sausage rolls?
    The base is mild, but adding chili flakes gives them a subtle warmth. You can easily adjust heat to your liking or omit entirely.
  • What cheese works best?
    Cheddar offers classic sharpness, mozzarella adds melty creaminess, but feel free to experiment with what you have on hand.

  • Yield: 12-16 sausage rolls
  • Category: Snack
  • Method: Baking
  • Cuisine: British

Ingredients

Meat Mixture

  • 1 lb (450g) pork mince (ground pork)
  • 1 packet French onion soup mix or 1 cup sautĂ©ed 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 – half for meat mixture
  • Chili flakes (optional, for heat)

Pastry and Assembly

  • 2 sheets puff pastry, thawed if frozen
  • Cheese (cheddar or mozzarella), grated or sliced
  • 1 egg + 1 tbsp milk, for egg wash

Instructions

  1. Preheat Oven: Preheat the oven to 400°F (200°C). Line a baking tray with parchment paper to prevent sticking and ensure easy cleanup.
  2. Prepare Meat Mixture: In a large bowl, combine the pork mince, French onion soup mix (or sautéed onions plus onion powder), tomato 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 to build a rich, savory flavor base.
  3. Assemble Sausage Rolls: On a lightly floured surface, unroll one sheet of puff pastry. Spoon the meat mixture into a long log along one of the long edges of the pastry, leaving about a 1/2-inch border free from filling to help with sealing. Place a strip of grated or sliced cheese on top of the meat filling to add gooey richness.
  4. Roll and Seal: Carefully roll the pastry over the filling to encase it completely, then pinch the seam closed securely to prevent the filling from leaking during baking. Repeat this process with the second sheet of pastry and remaining filling and cheese.
  5. Cut and Prepare for Baking: Using a sharp knife, cut each rolled log into 6–8 even pieces, depending on desired size. Place each piece seam-side down on the prepared baking tray to help maintain shape during cooking.
  6. Apply Egg Wash: In a small bowl, whisk together the egg and milk to create an egg wash. Brush this evenly over the tops of the pastry rolls; this will give them a lovely golden-brown color once baked.
  7. Bake: Bake in the preheated oven for 20–25 minutes until the pastry is golden brown and crisp, and the meat filling is cooked through. Remove from oven and allow to cool slightly before serving.

Notes

  • Using sautĂ©ed onions instead of French onion soup mix adds a fresher, more natural flavor.
  • Ensure puff pastry is well chilled before baking for optimal flakiness.
  • Feel free to adjust the herbs and chili flakes to suit your taste preferences.
  • Serve warm with mustard or your favorite dipping sauce for enhanced flavor.
  • These sausage rolls can be frozen before baking; bake straight from frozen by adding a few extra minutes to cooking time.
