Ingredients
Scale
Filling Ingredients
- 3 small potatoes, peeled and cut into eighths
- 1 tablespoon butter
- 1 large brown onion, halved and sliced
- 250 g (2 cups) mature cheddar cheese, grated (sharp cheddar)
- 2 small gherkins, finely chopped
- 1 teaspoon English mustard
- 1 teaspoon fresh thyme leaves
- ½ teaspoon sea salt (divided)
- ¼ teaspoon freshly ground black pepper
Pastry & Topping
- 1 sheet of pre-rolled puff pastry
- 1 medium egg, whisked (for egg wash)
- ½ tablespoon nigella seeds
- Plain flour (all-purpose flour) for dusting surface
Instructions
- Cook the potatoes: Place the peeled and cut potatoes in a pan of salted water and bring to a boil. Cook until tender, then drain thoroughly. Cover the potatoes and let them steam for a few minutes before mashing them with a potato masher. Transfer the mashed potatoes to a large mixing bowl and allow to cool.
- Caramelize the onions: While the potatoes cook, melt the butter in a frying pan over low-medium heat. Add the sliced onions and a small pinch of salt, cooking gently for about 25 minutes while stirring frequently until the onions turn golden brown and soft. Add the caramelized onions to the mashed potatoes and let cool.
- Prepare the filling: Once cooled, mix in the grated mature cheddar cheese, English mustard, finely chopped gherkins, and fresh thyme leaves into the potato and onion mixture. Season with half of the sea salt and the freshly ground black pepper. Stir thoroughly to combine all ingredients well.
- Assemble the rolls: Unroll the pre-rolled puff pastry onto a floured surface and gently roll it out slightly using a floured rolling pin. Cut the pastry lengthwise into two equal strips. Divide the cheese and onion filling evenly between the two strips, shaping the mixture into a long sausage shape along the center of each. Fold the pastry over the filling to encase it, then use a sharp knife to cut each roll into four equal portions, yielding eight rolls in total. (These can be frozen at this stage for later baking if desired.)
- Prepare for baking: Place the rolls on a baking tray lined with parchment paper. Brush each roll generously with the whisked egg to create a glossy finish, then sprinkle nigella seeds on top, distributing evenly over all rolls.
- Bake the rolls: Preheat your oven to 180°C (350°F) fan-assisted. Place the tray in the middle of the oven and bake for 25-30 minutes until the rolls puff up and turn a beautiful golden brown color. Once baked, remove the tray from the oven and transfer the rolls to a wire rack to cool slightly.
- Serve: Serve the cheese and onion rolls warm as a comforting snack or alongside a fresh salad for a light meal.
Notes
- You can freeze the assembled but unbaked rolls for up to 1 month; bake directly from frozen, adding a few extra minutes to the baking time.
- If you prefer a spicier kick, add a pinch of cayenne pepper or chili flakes to the filling mixture.
- Use sharp mature cheddar for a pronounced cheesy flavor that balances the sweetness of the caramelized onions.
- Ensure the potato mixture is fully cooled before adding the cheese to prevent it from melting prematurely.
- Nigella seeds add a subtle oniony flavor and decorative finish but can be omitted if unavailable.
