Mashed Potato Leftovers Are the Key
The great part about leftover mashed potatoes is that they are not as fluffy and light as they were the night before. That’s because all of their parts – butter, cream, and the starch in the potatoes – have had time to marinate and stiffen up a bit. As a result, leftover cheddar mashed potato waffles are even better, sturdier, and more flavorful than if you were using fresh mashed taters!
Tips for Making Mashed Potato and Cheddar Waffles
- First of all, preheat your waffle iron and grease well because you want all of that cheese to be stuck to your waffle, not to your iron! To make your waffles, scoop 1/3 to 2/3 cup (depending on the size of your waffle maker) of the potato mixture into the prepared hot waffle iron.
- Spread the batter out into an even layer. I suggest using a sturdy silicone spatula
for this. The potatoes barely stick, therefore it’s easy to use and to clean up. Now all that’s left is to close the waffle iron lid and let the waffle bake until golden brown and cooked throughout.
- Serve the waffles at once, garnished with sour cream, scallions and more cheese, if desired. If we happen to have some cooked bacon crumbles in the fridge, they really round out these waffles!
Can you freeze these waffles?
Yes. Once the waffles are cooked throughout and have fully cooled, place them in a single layer on a baking sheet. Place the waffles into the freezer and freeze solid; remove the frozen waffles to a freezer bag and seal well. Since the waffles have been individually frozen before they go into the freezer bag, you can now pull out as few or as many as you want at a time – super handy!
What other cheeses would be good in mashed potato waffles?
Great question. We’ve used Monterey Jack, Colby Jack, mozzarella and smoked Gouda – all delicious. You can use nearly any type of cheese and combination there of.
