Leftover Mashed Potato Balls

Why You’ll Love This Recipe

There are so many things you can do with leftover mashed potatoes, but these Leftover Mashed Potato Balls are my favorite way to use them.

I mean, mashed potatoes are pretty great to begin with, but add in some cheddar cheese, green onions and bacon, then coat them in breadcrumbs and fry them until crispy…..well, that makes them pretty much perfect!

Mashed potatoes are my kid’s favorite thing about Thanksgiving dinner, so I always make way more than I think we’ll need. You’d be surprised how many mashed potatoes a teenage boy can put away in one sitting!

But somehow I manage to usually have enough leftover to make these amazing mashed potato balls.

Dare I say, I love these bites of fried potato goodness more than the mashed potatoes themselves? And it’s pretty hard to improve on mashed potatoes, so that’s really saying something.

Leftover Mashed Potato Balls

The most important thing about having this recipe turn out successfully is using cold mashed potatoes. It really helps things stay together when you drop your potato balls in the hot oil for frying.

And if they fall apart a little, that’s okay. They’ll still taste delicious.

If you want to spice things up a bit, try adding some finely chopped jalapeno to your potato mixture. Or add a pinch of cayenne pepper to your breadcrumbs. 

I used seasoned Italian-style breadcrumbs in this recipe, which adds tons of great flavor. And my family strongly recommends serving these with a side of Ranch dressing, for dipping.

If you’re looking for something new to do with leftovers this holiday season, you’ve got to try these Leftover Mashed Potato Balls! You’re going to love them!
