How To Make Leftover Mashed Potato Cakes

Detailed instructions are in the recipe card below. But here is a quick step by step guide and the best way of how to make potato cakes with leftover mashed potatoes:

Steps 1, 2 & 3

• Pre-heat oven to 180C FAN and lightly oil a baking tray / baking sheet.
• In a frying pan over a medium heat in some hot oil sauté any onions, garlic or other veg that needs a little bit of cooking first to soften. Other vegetables to sauté might be leeks or celery.
• Then combine the sauted vegetables and any other leftover ingredients you are using in a bowl with your mashed potato. Give the ingredients in the bowl a good season with freshly grated salt and pepper.

Steps 4 and 5

Next, and this part is fun for kids to help out with!

• Using your hands roll the mashed potato mixture into 6 to 8 balls. If the potato mixture is too wet add a little plain flour.
• Place each ball onto the baking tray and flatten them out until they're about 1.5cm / 1 inch thick each.
• Place into fridge for about half an hour. This helps to firm them up a bit.

Step 5 cont.

• Bake in the centre of a preheated oven for about 20 minutes until lightly golden brown.
• When you remove the cooked delicious mashed potato cakes from the oven allow them to cool for a few minutes then serve.

Here's some other suggested leftover ingredients that you could use in your leftover mashed potato cakes......
