Ingredients
- Leftover Mashed Potatoes: We're starting with 3 cups of leftover mashed potatoes. This is a fantastic way to repurpose those extras from last night's dinner. If your mashed potatoes are already seasoned, great! If not, don't worry, we've got plenty of flavors coming up.
- Shredded Cheese: Next up, we're adding some cheesy goodness to our waffles with shredded cheese. Feel free to use your favorite variety here - cheddar cheese, mozzarella, or even pepper jack for a little kick would work wonderfully.
- Crumbled Cooked Bacon: For a savory punch and a hint of smokiness, we're incorporating crumbled cooked bacon. If you're vegetarian, you can easily swap this out with some sautéed mushrooms or bell peppers.
- Chopped Chives: These will add a subtle oniony flavor and a pop of color to our waffles. If you don't have chives on hand, finely chopped green onions will do the trick.
- Large Eggs, Lightly Beaten: Eggs act as a binding agent in our waffle batter, ensuring everything sticks together beautifully.
- Butter, Melted and Cooled: A little bit of butter goes a long way in enhancing the taste and texture of our waffles. Be sure to let it cool before mixing it in to avoid scrambling the eggs.
- All-Purpose Flour: This will give our waffles structure and ensure they hold their shape in the waffle iron. If you're gluten-free, a good quality gluten-free flour blend can be used instead.
- Baking Powder: A crucial ingredient for light and fluffy waffles. It will help our waffles rise and become wonderfully crispy.
- Sea Salt: Last but not least, a touch of sea salt to balance out all the flavors. If your mashed potatoes are already quite salty, feel free to adjust this to taste.

Tips and Tricks for Waffled Mashed Potatoes
- The Perfect Batter: The key to getting your waffles just right is the consistency of the batter. It should be thick enough to hold its shape but not so dense that it doesn't spread easily in the waffle iron. If it's too thick, add a splash of milk; if it's too thin, a bit more flour should do the trick.
- Mix-ins Galore: While our recipe calls for bacon and chives, there are tons of other delicious mix-ins you can try. Think diced ham, cooked sausage, chopped herbs like parsley or dill, or even some finely chopped spinach for a green boost.
- Waffle Iron Care: Don't forget to preheat your waffle iron before adding the batter, and always grease it well. This will ensure your waffles don't stick and come out golden and crispy every time.

Are potato waffles good for breakfast?
Absolutely! Potato waffles make a delicious and hearty breakfast or brunch option. Top with a fried egg, scallions, avocado, bacon, or a dollop of sour cream for an extra special treat.
Can I freeze potato waffles?
Yes, it's very easy to freeze potato waffles. Simply wrap each one in freezer-safe bags and store in the freezer for up to three months.
