Transform your leftover mashed potatoes into a delightful treat with these crispy cheesy potato waffles. Perfect for breakfast, brunch, or even a savory snack, these waffles are a delicious way to enjoy the comforting flavors of potatoes and cheddar cheese in a new and exciting form.
Most of the ingredients for this recipe are common pantry staples. However, if you don't usually keep green onions on hand, you might need to pick some up at the supermarket. They add a fresh, slightly pungent flavor that complements the richness of the cheddar cheese and mashed potatoes.

Ingredients for Crispy Cheesy Potato Waffles
Mashed potatoes: These form the base of the waffles, providing a creamy texture and rich flavor.
Cheddar cheese: Adds a sharp, tangy taste and helps to create a crispy, cheesy crust.
Green onions: Offer a fresh, slightly pungent flavor that balances the richness of the other ingredients.
Flour: Helps to bind the mixture together, ensuring the waffles hold their shape.
Egg: Acts as a binder, giving the waffles structure and helping them to crisp up.
Technique Tip for Perfect Potato Waffles
When mixing the mashed potatoes with the cheddar cheese, green onions, flour, and egg, ensure that the mashed potatoes are at room temperature. This allows the ingredients to combine more evenly, resulting in a smoother mixture. Additionally, for an extra crispy texture, consider adding a tablespoon of cornstarch to the mixture.
Suggested Side Dishes
Alternative Ingredients
mashed potatoes - Substitute with mashed sweet potatoes: Sweet potatoes offer a slightly different flavor profile and a bit more sweetness, which can add a unique twist to the waffles.
shredded cheddar cheese - Substitute with shredded mozzarella cheese: Mozzarella melts well and provides a milder flavor, which can be a good alternative if you prefer a less sharp taste.
chopped green onions - Substitute with chopped chives: Chives have a similar onion-like flavor but are milder and can add a subtle freshness to the dish.
flour - Substitute with cornstarch: Cornstarch can help achieve a crispy texture similar to flour and is a good gluten-free alternative.
egg - Substitute with flaxseed meal and water mixture: Mix 1 tablespoon of flaxseed meal with 3 tablespoons of water to replace one egg. This is a great vegan alternative that helps bind the ingredients together.

- Once frozen, transfer the waffles to a freezer-safe bag or airtight container. Label the bag with the date to keep track of their freshness.
- To reheat, preheat your oven to 375°F (190°C). Place the frozen waffles on a baking sheet and bake for 10-15 minutes, or until they are heated through and crispy.
- Alternatively, you can reheat the waffles in a toaster or toaster oven. Toast on medium heat until they are hot and crispy.
- For short-term storage, place the cooled waffles in an airtight container and refrigerate. They will stay fresh for up to 3 days.
- To reheat refrigerated waffles, use a toaster, toaster oven, or oven. Heat until they are warmed through and regain their crispiness.

How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the potato waffles on a baking sheet lined with parchment paper. Bake for 10-15 minutes, flipping halfway through, until they are heated through and regain their crispiness.
