We’ve all been there, after a holiday dinner that you slaved and prepared for the masses and you have leftovers. Leftovers are always better than not-enough. My mother always prepared meals as if a small army may arrive to join us at any given moment. While leftovers are awesome, they can get boring. Especially if you’re left with lots of them. Re-inventing those foods into something new can make those leftovers into brand new foods you can enjoy days after your feast. Mashed potatoes is a common leftover. Don’t waste them, use them in this recipe that makes them into something new in minutes. Perfect for breakfast with a freshly fried egg, or served as a side with dinner. However you choose to enjoy them, they’re the ultimate use for those day-old mashed potaters.

Servings: 4
Prep Time: 10 minutes
Cook Time: 5 minutes


  • 2 tbsp vegetable oil
  • 1/4 cup buttermilk
  • 2 large eggs
  • 2 1/2 cups of leftover mashed potatoes
  • 1/4 cup chopped green onions
  • 1/2 cup all purpose flour (can substitute with gluten-free flour)
  • 1 cup shredded cheddar cheese
  • 1/4 tsp baking soda
  • 1/2 tsp baking powder
  • Non-stick cooking spray
  • Sour cream or greek yogurt for dipping (optional)


  • Mixing bowls (2)
  • Spatula
  • Ladle
  • Waffle iron (belgian waffle iron used for this recipe)
  • Measuring cups


  • In a large bowl, mix together your oil, buttermilk and eggs. Add in the mashed potatoes, cheese and chopped green onions and stir until well combined.
  • Preheat your waffle iron.
  • In a separate bowl, combine your flour, baking powder, baking soda and fold it into the mashed potato mixture until combined.
  • Spray your waffle iron with non-stick cooking spray. Then, using a measuring cup or ladle, scoop 1/2 cup to 1/3 cup of the potato mixture into the center of your heated waffle iron. Spread using a spatula to make the layer even. Close the waffle iron lid, and let it bake until golden brown.
  • Transfer your waffle with a spatula or lift onto a serving plate, and repeat the steps above until you are out of batter.
  • NOTE: Depending on the original consistency of the mashed potato recipe, you may need to add an extra egg if it's too dry or alternatively extra flour a bit at a time if the mixture is too wet.
