This isn't like the traditional pasties that you would get in Cornwall (with beef and swede), but instead it is a cheese pasty with potato and onion added, just like the Greggs pasty (which they changed to be called a bake/slice).
Making them at home is much cheaper and they seriously taste next level. We added a little bit of mustard and it makes them even more delicious! A cheese and onion pasty makes a delicious addition to a picnic too.
This is a puff pastry recipe (using store bought for ease). If you are looking for more recipes that use puff pastry, then why not try our easy Mushroom Tartlets, delicious Apple Hand Pies or our simple Cheese Straws?

Why You Will Love It
- Comforting - A homemade pasty is super comforting and just proves that comfort food doesn't have to be complicated.
- Cheaper - I think I practically survived on a trip to Greggs for a cheese and onion pasty when I was at university! There was one right next to campus, so it was easy to just grab on the way into class. Now, if I had been making my own back then, I would have saved myself a lot of money. It's much cheaper to make yourself, as they are all fairly budget friendly ingredients.
- Adaptable - Use this cheese and onion pasty recipe as a base and then adapt with extra additions like we have suggested below.
- Healthier - Now, I am not going to convince you that these are healthy at all. Pastry and cheese is never going to be the most nutrient dense ingredients. However, you only have to look at the ingredients of the Greggs cheese and onion pasty to see that the ingredients list is HUGE! These are homemade, with no weird ingredients or fillers and additives.
Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Puff pastry - Not sure what pastry is used for a pasty? Well, it's puff pastry sheets in this case! Golden and flakey, it literally melts in your mouth.
- Potato - Now, Greggs cheese and onion pasty doesn't have chunks of potato in it like ours does (just some potato flakes for binding), but that is what makes ours better in my opinion. It makes it more filling and comforting. Make sure to dice the potato really small, so that they are cooked all the way through.
- Onion - Loads of flavour in the pasty comes from the onion. You could use shallots instead, which would have a sweeter flavour.
- Cheese - Cheese makes the best pasty filling in my opinion. Pastry and cheese - what is more comforting than that? We have used a matured cheddar, because it has such a strong flavour, and a little goes a long way.
- Egg - This helps to bind all the mixture together.
- Mustard - This is our (not so) secret ingredient. Some Dijon mustard just makes this cheese and onion pasty even better. You could use wholegrain or English mustard if you prefer. If you want a different flavour addition that also goes really well with cheese, then add some marmite.
More ingredient substitutions and variations can be found in the recipe card.
How to Make Greggs Cheese and Onion Pasty
Prep: Preheat your oven to 200°C/180°C(fan)/400°/Gas 6.
- Step 1: Put the potato, onion, egg, cheese and mustard into a bowl and mix well.
- Step 2: Cut the pastry into 8 equal sized squares/rectangles. Put 4 of the pastry squares onto a lined baking tray. Divide the cheese and onion mixture between the 4 pastry squares.
- Step 3: Place the remaining pastry squares over the cheese and onion mixture and crimp the edges with a fork to seal. Brush with egg wash and make a small incision in the top of the pastry.
- Step 4: Bake for 30-35 minutes.
Tips and Tricks
- Don't take the pastry out of the fridge too soon, as depending on how hot your kitchen is, the pastry might get too warm and it's difficult to work with. Take it out only about 10 minutes before you need to, so it isn't too cold either, as that will cause it to crack.
- The key to making these is not over stuffing the pastry, as they won't seal very well.
- You can make mini cheese and onion pasties by halving the rectangles of pastry and just making more. They are quite high in calories, so this is a good way to go if you want to make them lower in calories. These are great for party food too.
- Bacon makes everything better, so why not add some chopped bacon into the mixture? You could also add chopped ham for added protein.
- If you want to make a cheese and onion pasty without potato, then you can definitely do that. You might need to add a bit more filling into each pastry parcel though.
- You can add some fresh parsley to lighten it up a little bit.
- Make sure to generously season the mixture with salt and pepper.
- Don't forget to make the little incision at the top of the pastry before putting them in the oven. These are steam holes and they stop the pastry from getting soggy inside. If you want to make them look more like a Greggs pasty, then add 3 small arrow shapes for the steam holes. But you don't need to be that "fancy".
- To make a vegan cheese and onion pasty, make sure you use vegan pastry and cheese and skip the egg wash.
- Be careful when eating, as the filling will be piping hot!
Frequently Asked Questions
No, there is no need to cook the potatoes first, as the cook time in the oven is enough to make sure that the potato is cooked all the way through. Just make sure that the potato is diced very small. If the chunks are too big, then they will still be hard. If you wanted to add more flavour to the potato, then you could fry it in a little butter before adding to the cheese and onion mix, but that just adds to the prep time. It does give the potato a nice crunch though.
Yes, you technically could but we much prefer the results of using puff pastry, which is what you will get with a Greggs cheese and onion pasty. Shortcrust pastry makes it a bit too heavy, whereas puff pastry it light and flakey.
Allow them to completely cool and then you can store them in an air tight container in the refrigerator for 2-3 days. You can also freeze them. Wrap each one in cling film and then placing in a freezer bag. They will keep in the freezer for up to 2 months. If you do plan to freeze some, then freeze them before cooking and then defrost, egg wash and bake.
Make sure that they are fully defrosted (in the fridge overnight) and then you can put them in the oven at 180°C/350°/F/Gas 4 until they get crispy again and are hot all the way through. You could also reheat them in an air fryer at 180°C for 3-4 minutes. You can also eat these cold, which is what we do when we make mini versions to take on picnics. Our kids LOVE them.
These are best baked and eaten straight away, however you could make them in advance to save some time. Make them and put them on a baking tray, but don't add the egg wash. Put them in the fridge and then take them out about 30 minutes before you want to cook them to make sure they are not really cold in the middle and so they cook evenly. You can then egg wash and put in the oven.

This is very good, as other recipes pre-boil the tatties and that is a wee bit too much hassle for me. This works grand for sure and tastes muckle nice! Thank you very much!

Karen Cooper says
I tried these for the first time today and they were absolutely delicious! I did cook the potato a little while first(just until the water was boiling and the switched them off) and then cut them up and also cooked the onion a little to soften it.
