Savory French Onion Sausage Rolls (Print-Friendly Format)

Puff pastry filled with sausage and sweet caramelized onions for a golden, satisfying bite.

# Required Ingredients:

→ Filling

01 - 450 g ground sausage (pork, chicken, or turkey)
02 - 2 large onions, thinly sliced
03 - 2 tablespoons olive oil
04 - 1 teaspoon fresh thyme or ½ teaspoon dried thyme
05 - Salt and black pepper to taste
06 - Optional: 60 g grated Gruyère cheese
07 - Optional: 1 tablespoon Dijon mustard

→ Pastry

08 - 1 package puff pastry (2 sheets, thawed)

→ Finishing

09 - 1 egg, beaten

# How to Make It:

01 - Heat olive oil in a skillet over medium heat. Add sliced onions and a pinch of salt, then cook gently, stirring occasionally, until deeply golden and caramelized, approximately 15 to 20 minutes. Allow to cool slightly.
02 - In a bowl, mix ground sausage, caramelized onions, thyme, salt, and black pepper. Incorporate Gruyère cheese and Dijon mustard if desired.
03 - Preheat oven to 200°C. Line a baking sheet with parchment paper.
04 - On a lightly floured surface, unroll the puff pastry and cut into rectangles roughly 10 by 15 centimetres. Place a portion of filling along one side of each rectangle, fold the pastry over, and seal the edges with a fork.
05 - Transfer sausage rolls to the prepared baking sheet. Brush the tops with beaten egg. Bake for 20 to 25 minutes until the pastry is crisp and golden brown. Allow to cool slightly before serving.

# Additional Information:

01 - For a vegetarian alternative, substitute sausage with a mixture of sautéed mushrooms and cooked lentils.
02 - The unbaked rolls can be assembled ahead and frozen. Bake from frozen, adding a few extra minutes as needed.
