1 large onion
1,2kg potato, unpeeled
100g cheddar cheese, grated
100g mozzarella cheese, grated
10ml garlic salt
60ml butter, melted
Preheat your oven to 220℃ and line a 25cm x 37cm baking sheet with baking paper.
Grate the onion and potato on the coarse side of a box grater.
Transfer to a clean tea towel. Wrap the grated veg like a candy by twisting both ends. Hold the towel over a sink and wring it as firmly as you can to squeeze out any liquid.
Add the onion, potato, both cheeses and garlic salt to a large bowl and mix through.
Drizzle the butter over the mixture and now mix together with your hands so that all of the mixture is evenly dispersed and covered in butter.
Spoon the mixture into the prepared baking sheet but do not compact it by pressing down.
Bake in the oven for 40 minutes, until golden brown and crispy.
Serve immediately.
