Cheese and onion rolls are like a deliciously cheesy vegetarian alternative to sausage rolls. Crispy puff pastry stuffed with a cheese, potato and onion mix.
Preheat your oven to 200°C/180°C(fan)/400°F/Gas 6.
Add 2 Potatoes to a pan of boiling water. Return to the boil and simmer until tender, about 4-5 minutes.
Meanwhile, heat a pan and melt 2 tablespoon Butter. Add 1 Onion. Cook over a low heat until softened, about 5 minutes.
Drain the potatoes and leave to steam dry for a few minutes. Mash the potatoes.
Add 150 g Cheddar cheese, cooked onions, 2 Gherkins and 1 teaspoon English mustard to the mashed potato. Mix well to combine everything.
Slice 375 g Puff pastry lengthways in half. Divide the potato mixture along the two pieces of pastry.
Roll the pastry around the mixture. Repeat with the second roll and carefully turn the rolls over so they are seam side down.
Slice each roll into eight pieces. Brush with 1 Egg (whisked) and sprinkle over the 1 tablespoon Chia seeds.
Arrange the rolls on a lined baking tray with space in between them (a). Bake in the oven for 25 minutes (b).
Notes
If you are using ready rolled puff pastry, then you need to leave it out of the fridge for 15 minutes before you unroll it otherwise you will get cracks in it.
Cut through the pastry with a sharp knife. Don't drag your knife through it otherwise it will tear the pastry.
You can use less cheese in this recipe if you wanted to make them lighter, but you won't get that really cheesy flavour.
If you want to get the onions really caramelised, then you can add a little bit of brown sugar to them when they are cooking.
Although these are definitely best enjoyed warm, you will need to let them cool for about 10 minutes before serving as the cheese will be VERY hot inside straight from the oven.
The key to making these is not over stuffing the pastry, as they won't seal very well.
