This is Caramelised Onion, Cheese and Potato Puff Pie a fantastic, hearty dish. Best served with something light, like a salad and a spoonful of chutney. The filling could probably fill 3 pies – if you want to make a third, you’ll need an extra sheet of puff pastry. Lancashire Cheese works well, however if you can’t get hold of it, a good, strong Cheddar will work well. You’ll need a deep, small Pie Dish. A sprung form one would be ideal, however I have these.

Serves – 2
Prep / Cooking time – 50mins / 35mins

Caramelised Onion, Cheese and Potato Puff Pie Ingredients

Olive Oil
Splash of Balsamic Vinegar (optional)
1 Large Onion – Sliced
2 Sheets of Puff Pastry
100g finely grated Italian hard cheese – (Parmesan if you’re not a veggie!)
250g grated Lancashire cheese
500g Potatoes
150g Butter
10g Chives – Finely Chopped
1 egg (for glazing)


  1. Warm a few glugs of oil in a large pan, keep the temperature low.

  2. Add the onion, give it a good mix with the oil – then let it slowly brown. You’re wanting to caramelise the onion – NOT fry it. Don’t keep stirring it – just let the heat slowly caramelise the sugars in the onion.

  3. As the onion browns, chuck in a splash of Balsamic Vinegar and mix it. Stir the onion every few minutes so it doesn’t catch. The onions should be soft and sweet after about 25-30 minutes. Remove from the heat and set it to the side.

  1. Boil your potatoes for 25-30 minutes, drain and mash.
Mashed Potato and Butter
