These Loaded Mashed Potato Cakes are a new addiction of ours.

We can’t seem to stop eating them!

These are packed with all of our favorites like bacon, cheese, onions and of course, mashed potatoes.

The last few months I have been on a major mashed potato kick.

Not necessarily eating mashed potatoes as they are, but how to reuse leftover mashed potatoes.

I’ve been trying to come up with a list of different ways to use up leftover mashed potatoes.

This may seem odd to many who don’t know what leftover mashed potatoes are.

However for those of us who don’t know how to make a small batch of mashed potatoes, we need ideas on how to reuse them later.

These Loaded Mashed Potato Cakes are a perfect use for those leftover mashed potatoes!

OR you can be like us and go buy pre-made mashed potatoes whenever you want these cakes!

I first made these for lunch one day and thought they were really good.

My husband agreed that they were good and didn’t say another word.

I then took them to my usual gang of taste testers to see what their thoughts were and whether the recipe needed any tweaking.

Apparently they were a hit and everyone was asking how soon this recipe would hit the website.

What I didn’t realize is that the next day, my husband asked if we had any of the Loaded Mashed Potato Cakes left.

Apparently he liked them more than I thought because he wanted to have them for lunch again.

Not to worry though.  I had more bacon and more mashed potatoes and could whip up another batch quickly!

The overall comment on these was that frying them in the bacon grease really made all the difference.

The flavor and texture complimented each other and the added toppings make these perfect for a meal, side dish or even an appetizer!
