REPIN this Leftover Mashed Potato Pancakes recipe!






These were a big hit with my wife and my rather picky father-in-law (both from Belfast). I used leftover Champ and fried them in a butter/oil mixture as I think it browns a bit better. I’m sure they’ll have me making these on a regular basis!
That makes me so happy to hear Chris! We LOVE using leftover Champ for this recipe.
