• 100g soft cheese
• 200g cheddar or similar cheese, grated
• 50g butter

How to Make Potato Gratin

1. Preheat the oven to 180C/ gas mark 4.
2. Peel the potatoes and then slice them thinly- approximately 3mm thickness.
3. Layer the enough of the potatoes in an ovenproof dish to completely cover the bottom.
4. Season with salt and pepper.
5. Top and tail an onion and remove the skin. Cut in half lengthways.
6. Lie the onion on the flat side and slice thinly.
7. Spread the onion slices over the potatoes. 
8. Use two teaspoons to create small ‘dollops’ of soft cheese and dot these across the potatoes and onions.
9. Layer more potatoes over the top, overlapping slightly to create a pattern, as in the photos.
10. Cut the butter into small cubes and dot over the top of the potatoes.
11. Season with salt and pepper.
12. Put the dish in the oven and cook for 20 minutes.
13. Remove from the oven and add the grated cheese.
14. Return to the oven for 15 minutes or until the cheese is golden brown.

Here is the finished result with braised steak in onion gravy, fine beans, and julienne carrots.

Additional Tips for Making This Dish

• Transform the flavour of your potato gratin by adding herbs or garlic.
• Use a mandoline when slicing the potatoes to get even slices.
• Add some breadcrumbs to the topping for an extra crispy top.
• When you slice the potatoes, you will have small pieces and large pieces. Put the small pieces in the bottom of the dish and save the large slices for the top layer. This will make your potato gratin look more appealing.
