Nothing goes to waste in our kitchen.
Even those niggly little bits of odd leftover vegetables, like that stray spring onion. The one hiding in the fridge salad compartment!

What’s different about this one is that it doesn’t actually involve you having to buy anything to make the recipe!
You should be able to make this recipe with what you’ve got leftover in your fridge.
Further down this recipe I’ve added a list of other leftovers you might have to hand.
Suggesting different variations of this mashed potato cake recipe. Hopefully helping you to find creative inspiration for your leftover potatoes.
I’ve also made this an oven baked potato cakes recipe, rather than completely fried. The onion and garlic are sauted at the start, just to soften them and bring out their flavours.
Other than that though. we’re keeping this potato cakes recipe as healthy as possible!
So, let’s start off this deliciousness.
First 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.
Next, and this part is fun for kids to help out with!
Using your hands roll the 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.
Bake in the centre of a preheated oven for about 20 minutes until lightly golden brown.
When you remove the cooked potato cakes from the oven allow them to cool for a few minutes then serve.
I serve my leftover mashed potato cakes with an iceberg lettuce salad and some garlic mayonnaise. That just keeps this dinner recipe nice and simple!
