Mini Cheese & Onion Pasties Recipe
Introduction
These mini cheese & onion pasties are a perfect savory treat, combining a crisp, buttery pastry with a flavorful filling of caramelized onions, sharp cheddar, and mustard. Ideal for picnics, snacks, or a light meal, they’re easy to make and delicious served warm or cold.

Ingredients
- 1 tbsp vegetable oil
- 2 onions, sliced
- 4 thyme sprigs, leaves picked
- 150g mature cheddar (or a mixture of strong hard cheeses), grated
- 1 tbsp wholegrain mustard
- 4 spring onions, sliced
- 250g plain flour, plus extra for dusting
- 125g cold butter
- Large pinch of cayenne pepper
- ½ tsp English mustard powder
- 1 large egg, beaten
Instructions
- Step 1: Make the pastry by tipping the flour into a bowl. Grate the cold butter directly into the flour, dipping the butter in flour if it gets sticky. Add cayenne pepper, mustard powder, half the beaten egg, and a pinch of salt. Mix with your hands until it begins to clump.
- Step 2: Tip the mixture onto a work surface and knead briefly into a smooth ball, adding up to 3 tablespoons cold water if too dry. Flatten into a disc, wrap, and chill while preparing the filling.
- Step 3: Heat the oil in a frying pan. Cook the sliced onions and thyme leaves for 8–10 minutes until softened and caramelized. Transfer to a bowl to cool.
- Step 4: Once cooled, stir in the grated cheese, wholegrain mustard, and sliced spring onions.
- Step 5: Preheat the oven to 200°C (180°C fan/gas mark 6) and line a baking tray with parchment paper.
- Step 6: Roll out the chilled pastry on a lightly floured surface to about the thickness of a £1 coin. Cut 10-12 circles about 10–12 cm in diameter using a cup or mug as a template. Re-roll scraps as needed.
- Step 7: Place a mound of filling in the centre of each pastry circle, keeping the edges clear. Brush the edges with some remaining beaten egg, fold in half to form a half-moon, and pinch the edges to seal. Crimp edges decoratively, then place on the baking tray.
- Step 8: Brush the tops with beaten egg. Bake for 20–25 minutes until golden brown. For frozen pasties, bake for 40–45 minutes.
- Step 9: Allow to cool for at least 10 minutes before serving warm, or cool completely for packing in containers for a picnic.
Tips & Variations
- For extra flavor, add a small amount of finely chopped garlic or a pinch of smoked paprika to the filling.
- Try using a mix of cheeses, such as mature cheddar with a crumbly Lancashire or Red Leicester, for a richer taste.
- Chill the pastry disc well before rolling to make it easier to handle and create flakier crusts.
- These pasties freeze well—bake from frozen for a convenient ready-to-eat snack.
Storage
Store cooked pasties in an airtight container in the fridge for up to three days. Reheat them in a preheated oven at 180°C (160°C fan/gas 4) for about 10 minutes until warmed through. Unbaked pasties freeze well for up to two months; bake directly from frozen, increasing baking time to 40–45 minutes.

FAQs
Can I make these pasties gluten-free?
Yes, you can substitute the plain flour with a gluten-free pastry flour blend, but be aware the texture may differ slightly. Ensure the blend is suitable for pastry to maintain a flaky crust.
What can I use instead of cheddar cheese?
Any strong hard cheese like Red Leicester, Lancashire, or even a mature Gouda works well. You can also mix cheeses to balance sharpness and creaminess according to your preference.

Description
These Mini Cheese & Onion Pasties are deliciously flaky and packed with a savory filling of caramelized onions, mature cheddar cheese, and a touch of mustard. Perfect for a snack or picnic, these golden half-moon pastries combine buttery homemade pastry with a rich, tangy cheese filling, baked to perfection until golden and crisp.
Ingredients
Pastry
- 250g plain flour, plus extra for dusting
- 125g cold butter
- large pinch of cayenne pepper
- ½ tsp English mustard powder
- 1 large egg, beaten (half for pastry, remainder for brushing)
- pinch of salt
- up to 3 tbsp cold water (optional, to help bind dough)
Filling
- 1 tbsp vegetable oil
- 2 onions, sliced
- 4 thyme sprigs, leaves picked
- 150g mature cheddar cheese (or mixture of strong hard cheeses), grated
- 1 tbsp wholegrain mustard
- 4 spring onions, sliced
Instructions
- Make the pastry: Tip the flour into a bowl. Grate the cold butter directly into the flour, dipping the butter end into flour occasionally to prevent sticking. Add cayenne pepper, mustard powder, half of the beaten egg, and a pinch of salt. Bring the mixture together with your hands until it starts to clump. Turn onto a floured surface and knead briefly into a smooth ball, adding up to 3 tbsp cold water if too dry. Flatten into a disc, wrap, and chill while preparing the filling.
- Prepare the filling: Heat the vegetable oil in a frying pan over medium heat. Add sliced onions and thyme leaves. Cook for 8-10 minutes until onions soften and begin to caramelize. Transfer to a bowl and let cool. Once cooled, mix in grated cheese, wholegrain mustard, and sliced spring onions until well combined.
- Preheat oven and prepare pastry circles: Heat the oven to 200°C (180°C fan)/Gas Mark 6. Line a baking tray with parchment paper. Roll out chilled pastry on a lightly floured surface to about the thickness of a £1 coin. Using a 10-12cm diameter cutter (or cup), cut out 10-12 circles. Re-roll scraps and cut additional circles as needed.
- Assemble the pasties: Spoon a mound of filling onto the center of each pastry circle, leaving edges clear. Brush the edges with the remaining beaten egg, then fold the pastry into a half-moon shape, pressing edges firmly and crimping to seal completely. Place assembled pasties on the baking tray. Brush the tops with beaten egg.
- Bake: Bake the pasties in the preheated oven for 20-25 minutes until the pastry is a deep golden brown. If baking from frozen, bake for 40-45 minutes. Once baked, allow the pasties to cool for at least 10 minutes before serving warm, or cool completely for packing in containers.
Notes
- The pastry can be frozen for up to two months before baking.
- Cooked pasties keep well in an airtight container for up to three days.
- For best results, use a sharp knife or pastry cutter for neat edges when sealing.
- Adjust cayenne pepper to taste for less or more heat.
- If the pastry dough feels dry, add water sparingly to keep the texture flaky.
- Serve warm or cold as a convenient picnic snack.
