Prevent waste and reimagine your leftovers!
My favorite thing to do after hosting a big meal like Thanksgiving dinner is to start to brain storm about how I can use my leftovers in creative ways. I put an emphasis on using and preserving the leftovers so I can big batch from scratch some easy meals that will feed us on days where I just don’t feel like cooking.
By using the leftovers creatively is prevents my family from getting board with just having the same meal reheated 3 nights in a row. Think of your leftovers as scratch made ingredients that you can use to build a new meal.
Sourdough Discard meets leftover mashed potato
The reason I came up with this leftover mashed potato sourdough discard waffle recipe is because I had a lot of sourdough discard stacking up in the fridge. So I set out and made a bunch of waffles to individually wrap and put into the freezer.
The next day was thanksgiving and I purposely made twice the mashed potatoes that we would eat that day so that I could use the leftovers to make shepherd’s pie.
Some people call the day after thanksgiving “Black Friday” and they go out and wrestle complete strangers for a free $15 door prize. I call the day after thanksgiving “Soup Day” and I spend the day making soup with the broth I made with the turkey carcass overnight.
Knowing I will be chopping onion, carrot and celery for the soup means that I can add a few more of everything and have my shepherd’s pie prep done at the same time. Brilliant, I know, but what does this have to do with waffles?
I was in the middle of prepping the veggies for the soup and shepherd’s pie and my kid asked for breakfast. I looked at the mashed potatoes, the waffle maker, the sourdough starter on the counter and I quickly tossed the batter together in a bowl and had breakfast on the table in 15 minutes.

sourdough discard mashed potato waffles
It couldn’t be easier. Here is how I make these leftover mashed potato discard waffles.
Equipment
- bowl
- fork
- waffle maker, I use this one
ingredients
- left over mashed potato
- egg
- sourdough discard
- baking powder (optional)
- salt and pepper to taste
Method
- Preheat your waffle iron.
- Mix about a cup of left over mashed potato with a couple tablespoons of sourdough discard and one chicken egg.
- Mix well then add 1/2 teaspoon of baking powder (if using) and mix again.
- If your mashed potatoes were very dry to begin with you can add a little milk or cream until you’ve got a thick batter consistency.
- Add batter to waffle maker as you would with normal waffles.
- Cook until less steam is escaping, the waffles are golden brown and release easily from the waffle iron.
- I like serving mine topped with a sunny side up egg and some kimchi or sauerkraut.
What if I don’t have sourdough discard?
You can skip the discard and just add a little plain flour, or even almond flour. Bread crumbs would also work. Just something to dry things out and bind with the egg a bit. You can also use ripe sourdough starter too.
I like using the discard because it gives it a little tangy flavor. I also really appreciate that when I use discard I’m using fermented rather than plain flour, which can be easier to digest.

What is mashed potato soup?
I literally just add a little bit of leftover mashed potato to my already finished turkey or chicken soup and heat it through. It makes it creamy and delicious.
I never add noodles to my pot of soup, I always cook them separately and add them to each bowl. This way, the base of the soup can be more versatile.
Skip the noodles and add some leftover mashed potatoes instead!
How to reheat leftover mashed potatoes without a microwave?
If you’re like me and you’ve evicted your microwave from your kitchen, you’re probably a pro at reheating leftovers with out using a microwave. Even if you have a microwave available you might find it’s worth it to take the extra time to reheat your leftovers a different way because the taste and texture are much better!
- In a sauce pan over medium low heat with some added water, milk or broth. Stir frequently.
- In the oven in a covered dish with some added broth or water. 350 f until heated through, about 20 – 30 minutes.

How do you use your leftover mashed potatoes?
Leftover mashed potatoes are one of my favorite ingredients to repurpose. They can be used in so many ways. It’s a blank slate! I always find myself doubling the mashed potatoes needed for a meal just so I have leftovers to work with.
I’m sure to use my leftover mashed potatoes within a day or two so I don’t waste my efforts and let them spoil in the fridge. There’s nothing more disappointing than to go to use your leftovers and find them smelling sour or covered in fuzzy mold.
If you can’t think of anything to do, at least chuck them in the freezer for safe keeping until the time is right.
Have you ever repurposed yesterday’s mashed potatoes into something delightful? Let me know in the comments. Thanks for reading!
