One of the unspoken truths in life is that whenever you make mashed potatoes you will make way too many. I don’t care how much you calculate or guesstimate, at the end of any dinner where mashed potatoes are involved you will have a Tupperware dish of homogeneous potato hanging out in your fridge afterwards. Could you just eat them with tomorrow’s dinner? Sure, but….day old mashed potatoes aren’t quite as good as fresh.

What to Make with Leftover Mashed Potatoes

There are a couple ways to handle this. You could whip up a batch of homemade Refrigerator Rolls and wow all of your friends with your ability to make homemade bread.

If you’ve got enough, you could simply add the potatoes to a saucepan and add in more milk and stir up a batch of potato soup

OR you could make everyone super duper happy and make some of these easy leftover mashed potato cakes.

How to Make Leftover Mashed Potato Cakes

This leftover mashed potato recipe is a basic one. You can take it and run wherever the leftovers in your fridge take you. Got a bunch of shredded cheese? Great, add it in.

Want to work some veggies into your toddlers diet? Excellent, stir in some cooked carrots or even cabbage. The Irish make a version of potato cakes with leftover fish (I think salmon or cod would be perfect in here)

You could even make these ahead, fry them and freeze them and then just pop them in a hot oven to warm them up. Great for a party! I’ve topped these with sour cream and bacon, but the possibilities are endless. Check out the handy video to see how it’s done!
