How to Make Savory French Onion Sausage Rolls

1. Caramelize the Onions:
Melt butter in a large skillet over medium-low heat. Add onions, sugar, salt, and thyme. Cook, stirring often, for 25–30 minutes until onions are golden and caramelized. Stir in Worcestershire sauce and cook another minute. Let cool slightly.

2. Prepare the Filling:
In a large bowl, combine sausage meat with cooled caramelized onions (and cheese if using). Mix until evenly combined.

3. Fill and Roll:
Roll out puff pastry on a lightly floured surface. Cut in half to form two rectangles. Divide the filling and shape into logs along one long edge of each rectangle.

4. Seal and Slice:
Brush the far edge with egg wash. Roll up pastry tightly over the filling, seam-side down. Slice each roll into 4–6 pieces.

5. Bake:
Place rolls on a parchment-lined baking sheet. Brush tops with egg wash and cut a small slit in each for steam.
Bake at 400°F (200°C) for 22–26 minutes, until golden and crisp.

6. Serve:
Cool a few minutes. Sprinkle with fresh parsley and serve warm or at room temperature.

Tips for Success

• Low & Slow for Onions: Take your time caramelizing—this is where the flavor happens!

• Egg Wash for Shine: Don’t skip this step for a beautiful finish.
• Steam Vents: Always cut a slit in each roll to avoid sogginess.
• Cheese Lovers: Top with extra Gruyère before baking for a bubbly crust.

Common Mistakes to Avoid

• Rushing Onions: Caramelize slowly for the best taste.
• Soggy Pastry: Cool the onion mixture and don’t overfill.

How to Store & Reheat
