Step‑by‑Step Instructions for Savory French Onion Sausage Rolls
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven heats up, line a baking tray with parchment paper to prevent sticking. This setup ensures your Savory French Onion Sausage Rolls have a perfect, crisp base once they’re baked.
Step 2: Caramelize the Onions
In a large skillet, melt 2 tablespoons of unsalted butter along with 1 tablespoon of olive oil over medium heat. Add 2 medium, finely sliced onions and cook them for about 20 minutes, stirring occasionally, until they turn a rich, golden brown. If they start to stick, deglaze the pan with a splash of water.
Step 3: Add Garlic and Seasonings
Once your onions are caramelized, stir in 2 cloves of minced garlic, 1 teaspoon of fresh thyme leaves, and 1 teaspoon of Worcestershire sauce. Season with salt and pepper to taste, then cook for an additional 2 minutes. Remove from heat and allow the mixture to cool slightly before combining it with the sausage.
Step 4: Cook the Sausage
In another skillet, cook 1 pound of Italian sausage over medium heat, breaking it apart as it browns. Cook until fully cooked through, which should take about 8-10 minutes. Once done, drain excess fat and let it cool for a few moments to ensure it doesn’t melt the pastry when combined.
Step 5: Combine Ingredients
In a large bowl, mix the cooked sausage with the cooled onion mixture and fold in 1 cup of shredded Gruyère cheese. Stir until everything is evenly combined, creating a luscious filling for your Savory French Onion Sausage Rolls.
Step 6: Prepare the Puff Pastry
Dust a lightly floured surface with flour and roll out the thawed puff pastry sheets to smooth out any creases. This will help achieve that signature flaky texture. Once rolled, cut each pastry sheet into rectangles, approximately 4 inches by 6 inches.
Step 7: Fill the Pastry
Take a generous spoonful of the sausage and onion filling and place it onto one end of each pastry rectangle. Be careful not to overfill, as you need space to seal the rolls properly.
Step 8: Seal the Rolls
Fold the opposite end of the pastry over the filling and press down firmly to seal the edges, using a fork to crimp and secure the filling inside. This ensures no delicious goodness escapes while baking your Savory French Onion Sausage Rolls.
Step 9: Egg Wash and Bake
Arrange the sealed rolls on the prepared baking tray, leaving some space between them. Brush the tops with the beaten egg, giving them a beautiful golden finish. Bake in the preheated oven for 20-25 minutes, or until they are puffed and golden brown.
Step 10: Cool and Serve
Once baked, remove the Savory French Onion Sausage Rolls from the oven and allow them to cool slightly on a wire rack. This will help the filling set a bit before serving, so you can enjoy these comforting bites fresh from your kitchen.

Make Ahead Options
These Savory French Onion Sausage Rolls are perfect for busy cooks looking to save time during the week! You can prepare the filling (sausage and onions mixed with cheese) up to 3 days in advance. Simply store it in an airtight container in the refrigerator to maintain its flavor. For the puff pastry, you can roll and cut it into rectangles, then layer them with the prepared filling and keep them wrapped tightly in plastic wrap for 24 hours before baking. When you’re ready to enjoy, just preheat your oven and brush the tops with the beaten egg, then bake as directed for freshly baked rolls that are just as delicious!

Savory French Onion Sausage Rolls Recipe FAQs
What type of onions should I use for the best flavor?
I highly recommend using yellow onions; they caramelize beautifully and lend a sweet, rich flavor to your Savory French Onion Sausage Rolls. If you're looking for a bit of a twist, you could also try using sweet Vidalia onions for a more delicate sweetness.
How can I store leftover sausage rolls?
To keep your Savory French Onion Sausage Rolls fresh, store them in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy them again, simply reheat in the oven at 350°F (175°C) for about 10-15 minutes. This will allow the pastry to regain that delightful crispiness!
Can I freeze these sausage rolls before baking?
Absolutely! To freeze, wrap each assembled roll tightly in plastic wrap, and then wrap them again in aluminum foil to prevent freezer burn. You can store them in the freezer for up to 2 months. When ready to bake, let them thaw in the fridge overnight before baking directly from the fridge. Just add an additional minute or two to the baking time for the best results.
What if my pastry is too warm to work with?
If you find that your puff pastry is a bit too warm and sticky, just pop it back in the fridge for about 15-20 minutes. Chilling it for this short time will make it much easier to work with, allowing you to cut and fill your Savory French Onion Sausage Rolls without any trouble.
Are these sausage rolls suitable for kids?
Yes, they can definitely be enjoyed by kids! If you're concerned about spice, I recommend sticking with mild Italian sausage and perhaps reducing the amount of garlic to suit younger palates. This way, everyone in the family can savor the delicious flavors without any hesitation!
What can I do if my cheese isn't melting well?
Should your Gruyère cheese not melt as desired, check that it’s a good quality and shredded finely, as this will help it melt uniformly. You can also combine it with a little cream cheese or sour cream before mixing it with the filling; this can help produce a creamy consistency if melting is an issue!
