Garlic Parmesan air fryer mashed potato cakes are one of our favorite side dishes with creamy mashed potatoes. I love how they turn out crispy, cheesy and garlicky. And with a dollop of sour cream on top, a bit of bacon crumble and a scallion you’ll get a loaded mashed potato cake experience.

Potato Tips for the Best Air-fried Potato Cakes

Be sure your mashed potatoes are not too liquid or runny. If they are on the runnier side, you may need to add extra flour to make the batter thicker.

Work with cold mashed potatoes that were sitting in the fridge for a while. Best overnight mashed potatoes.

While boxed mashed potatoes may work, it is better to make real mashed potatoes from scratch.
