Ingredients:
- 1 pound (450g) of sausage meat (you can use pork, chicken, or a mix)
- 2 large onions, finely sliced
- 2 tablespoons of olive oil
- 1 tablespoon of unsalted butter
- 1 teaspoon of sugar
- 1 teaspoon of salt
- 1 teaspoon of black pepper
- 1 teaspoon of dried thyme
- 1 tablespoon of balsamic vinegar
- 1 tablespoon of Dijon mustard
- 1 sheet of puff pastry (thawed if frozen)
- 1 egg, beaten (for egg wash)
- Flour, for dusting
Preparing the Filling
- Start by heating the olive oil and butter in a large skillet over medium heat. Once the butter has melted, add the finely sliced onions.
- Sprinkle the sugar and salt over the onions. This will help to caramelize them and bring out their natural sweetness.
- Cook the onions, stirring occasionally, for about 15-20 minutes until they are soft and golden brown. If they start to stick to the pan, you can add a splash of water to deglaze it.
- Once the onions are caramelized, add the black pepper, dried thyme, and balsamic vinegar. Stir well and cook for another 2-3 minutes to let the flavors meld together. Remove from heat and let the mixture cool slightly.
Preparing the Sausage Mixture
- In a large mixing bowl, combine the sausage meat with the Dijon mustard. This adds a nice tangy flavor to the filling.
- Once the onion mixture has cooled a bit, add it to the sausage meat. Mix everything together until well combined. I like to use my hands for this, but you can also use a spoon if you prefer.
- At this point, taste the mixture and adjust the seasoning if necessary. You might want to add a bit more salt or pepper depending on your taste.
Assembling the Sausage Rolls
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
- On a lightly floured surface, roll out the puff pastry sheet to smooth out any creases. You want it to be about 1/8 inch thick.
- Cut the pastry into rectangles, about 4 inches wide and 6 inches long. You can adjust the size based on how big you want your sausage rolls to be.
- Place a generous amount of the sausage and onion mixture along one edge of each pastry rectangle, leaving about an inch of space at the edges.
- Fold the pastry over the filling to create a roll. Make sure to seal the edges well by pressing them together with your fingers or using a fork to crimp them.
- Place the assembled sausage rolls seam-side down on the prepared baking sheet.
- Brush the tops of the rolls with the beaten egg. This will give them a beautiful golden color when baked.
Cooking the Sausage Rolls
- Once all the sausage rolls are assembled and brushed with egg wash, place them in the preheated oven.
- Bake for about 25-30 minutes, or until the pastry is puffed and golden brown. Keep an eye on them towards the end to ensure they dont burn.
- When they are done, remove the sausage rolls from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack. This helps to keep the bottoms crispy.
Serving Suggestions
- These French onion sausage rolls are delicious served warm or at room temperature. You can serve them as an appetizer, snack, or even as part of a main meal.
- Consider pairing them with a side of mustard or a tangy dipping sauce for an extra flavor boost.
- They also go wonderfully with a fresh salad or some roasted vegetables for a more complete meal.
