Savory French Onion Sausage Roll Ingredients
• Here’s everything you’ll need to create these delicious rolls!
For the Pastry
- Puff pastry – 1 package (about 1 pound), thawed; this forms the flaky outer layer that envelopes the savory filling.
For the Filling
- Italian sausage – 1 pound (mild or spicy); the star ingredient that brings robust flavor to these Savory French Onion Sausage Rolls.
- Onions – 2 medium, finely sliced; caramelizing them elevates their sweetness and depth.
- Unsalted butter – 2 tablespoons; adds richness and helps caramelize the onions to golden perfection.
- Olive oil – 1 tablespoon; combined with butter for sautéing the onions.
- Garlic – 2 cloves, minced; infuses the filling with aromatic charm.
- Fresh thyme leaves – 1 teaspoon (or ½ teaspoon dried thyme); enhances the overall flavor with its earthy notes.
- Worcestershire sauce – 1 teaspoon; adds a depth of umami to the filling.
- Gruyère cheese – 1 cup, shredded; brings creaminess and a nutty flavor that complements the other ingredients.
For Assembly
- Egg – 1, beaten (for egg wash); gives the rolls a golden, shiny finish when baked.
- Salt and pepper – to taste; essential for seasoning the filling and elevating the dish.
Step‑by‑Step Instructions for Savory French Onion Sausage Rolls
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) and lining a baking tray with parchment paper. This ensures your Savory French Onion Sausage Rolls have a non-stick surface to bake on, allowing them to achieve that perfect golden crust.
Step 2: Sauté the Onions
In a large skillet, melt 2 tablespoons of unsalted butter with 1 tablespoon of olive oil over medium heat. Once the butter is fully melted, add the finely sliced onions. Stir them occasionally and let them cook for about 20 minutes until they are caramelized and golden brown. If the onions start to stick, splash in a little water to deglaze the pan.
Step 3: Mix in Aromatics
Add 2 minced garlic cloves, 1 teaspoon of fresh thyme leaves, and 1 teaspoon of Worcestershire sauce to the caramelized onions. Sprinkle in salt and pepper to taste, then sauté for an additional 2 minutes. Remove this beautiful mixture from the heat and let it cool while you prepare the sausage.
Step 4: Cook the Sausage
In another skillet, cook 1 pound of Italian sausage over medium heat until it’s browned and fully cooked, breaking it apart with a spatula as it cooks. Make sure no pink remains, then drain any excess fat and let the sausage cool slightly while you combine it with the onions.
Step 5: Combine Filling Ingredients
In a large mixing bowl, combine the cooled sausage with the caramelized onion mixture. Add in 1 cup of shredded Gruyère cheese and mix everything well until evenly combined. This delicious filling brings together the flavors of the Savory French Onion Sausage Rolls, making it irresistible.
Step 6: Roll Out the Pastry
Flour a clean surface lightly and roll out the thawed puff pastry sheets to smooth out any creases. You'll want the pastry to be pliable and ready for the filling. Gather your ingredients, as the assembly part is just around the corner!
Step 7: Cut the Pastry
Using a sharp knife, cut each pastry sheet into rectangles measuring approximately 4 inches by 6 inches. This size is ideal for holding the savory filling without overwhelming the flaky crust of the Savory French Onion Sausage Rolls.
Step 8: Fill the Pastry
Place a generous spoonful of the sausage and onion filling onto one end of each pastry rectangle. Ensure you leave some space at the edges to allow for sealing. This filling is what makes the rolls so delightful and packed with flavor!
Step 9: Seal the Rolls
Fold the other end of the pastry over the filling and carefully seal the edges by pressing down with a fork. Make sure they’re securely closed to prevent any deliciousness from leaking during baking.
Step 10: Prepare for Baking
Arrange the rolls neatly on the prepared baking tray. Take the beaten egg and brush it gently over the tops of the Savory French Onion Sausage Rolls using a pastry brush. This egg wash will help achieve that lovely golden finish.
Step 11: Bake to Perfection
Place the baking tray in the preheated oven and allow the rolls to bake for about 20-25 minutes. Keep an eye on them; they should puff up and turn golden brown, filling your kitchen with an enticing aroma.
Step 12: Cool and Serve
Once baked, remove the rolls from the oven and let them cool slightly on the tray. This cooling period is essential for handling. Serve your delightful Savory French Onion Sausage Rolls warm, and watch them disappear happily!

How to Store and Freeze Savory French Onion Sausage Rolls
Fridge: Store leftover Savory French Onion Sausage Rolls in an airtight container in the fridge for up to 3 days to maintain freshness and flavor.

Reheating: To reheat cooked rolls, place them in a 350°F (175°C) oven for about 10-15 minutes until warmed through and crispy. Avoid microwaving, as it may make the pastry soggy.
