Ingredients
Scale
For the Filling
- 1 tablespoon olive oil
- 2 medium yellow onions, thinly sliced
- 1 teaspoon sugar
- 1 teaspoon balsamic vinegar
- 1 pound ground pork sausage
- 1 teaspoon Dijon mustard
- 1/2 teaspoon dried thyme
- 1/4 teaspoon black pepper
For the Pastry
- 1 sheet puff pastry (thawed if frozen)
- 1 egg (beaten, for egg wash)
- Sesame seeds or poppy seeds (optional, for topping)
Instructions
- Caramelize Onions: Heat olive oil in a skillet over medium heat. Add the thinly sliced onions and cook slowly for 15–20 minutes, stirring occasionally until softened and golden brown. Stir in sugar and balsamic vinegar, cook an additional 5 minutes to caramelize. Remove from heat and allow to cool.
- Prepare Sausage Mixture: In a large bowl, combine the ground pork sausage, Dijon mustard, dried thyme, black pepper, and the cooled caramelized onions. Mix thoroughly until the ingredients are well incorporated.
- Preheat Oven and Prepare Pastry: Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper. On a lightly floured surface, roll out the puff pastry and cut it lengthwise into two equal rectangles.
- Assemble Rolls: Divide the sausage mixture evenly between the two pastry strips. Shape the filling into logs along the center of each pastry piece. Fold the pastry over to encase the filling and press the edges with a fork to seal, placing the rolls seam-side down on the prepared baking sheet.
- Apply Egg Wash and Toppings: Brush the tops of the rolls with the beaten egg to give a glossy finish. Sprinkle sesame or poppy seeds over the rolls if desired for added texture and flavor. Slice each roll into 4–6 bite-sized pieces.
- Bake: Bake the sausage rolls in the preheated oven for 25–30 minutes, or until puffed, golden brown, and cooked through. Remove from the oven and let cool slightly before serving.
Notes
- You can prepare the sausage and onion filling a day in advance to save time on the day of baking.
- Serve these rolls warm with a side of mustard or aioli for dipping to enhance the flavor.
- Use all-butter puff pastry for the best flavor, flakiness, and texture as opposed to margarine-based versions.
