Have you ever made too much mashed sweet potatoes for Thanksgiving or another holiday feast?

Don’t worry, because I have some quick ideas on what to do with those leftovers.

Whether you want to make a savory or sweet dish, there’s something for everyone.

So bookmark this post and get creative in the kitchen with your leftover mashed sweet potatoes.

Turn them into sweet potato fries

Turning your leftover mashed sweet potato into some form of fries is the most obvious way to use your leftover sweet potatoes.

First, you need to peel your potatoes and slice them into fry-size pieces.

Then, coat the sweet potato slices with olive or canola oil and sprinkle sea salt over each one.

Bake the fries at 425 degrees for 40 to 45 minutes on a baking sheet lined with tin foil.

Check on the fries every 10 minutes or so.

They should be browned on all sides and crispy when ready.

Make a sweet potato hash

Hash is another easy way to use up your leftover mashed sweet potatoes.

You’ll need a clove of garlic, onion, fresh mushrooms, leftover carrots or parsnips (optional), and olive oil for this dish.

First, chop everything into small pieces and saute it in a pan for 5 to 10 minutes.

Then add your leftover sweet potatoes and season with sea salt and pepper.

Saute everything together for another 10 to 15 minutes, stirring frequently.

Serve with an egg on top and enjoy.

Bake some sweet potato bites

Sweet Potato Bites are another quick and easy appetizer that can be made with leftover mashed sweet potatoes.

Just scoop out small bits of your cooked sweet potato with a spoon, place them on a sheet lined with tin foil, top them with cheese and bake for 10 minutes at 400 degrees.

I recommend using sharp cheddar for this recipe.

Turn them into muffins

Turning your leftovers into a baked good is another option for easy, delicious meals or snacks.

You can make sweet potato muffins by adding an egg, cinnamon, nutmeg, vanilla extract, and baking powder to your mashed sweet potatoes.

Then, scoop the mixture into a greased muffin pan lined with cupcake liners and bake for 30 minutes at 400 degrees.

The muffins will come out moist on the inside but crispy around the edges.

Make a mashed potato pie

Mashed potato pie is probably the most creative way to use up your leftovers.

You’ll need eggs, flour, salt, pepper, butter or olive oil, milk, and of course-mashed sweet potatoes.

First, combine three eggs with 1/2 cup of melted butter in a large bowl.

Add flour, salt, pepper, and milk until it reaches a doughy consistency.

Pour the mixture into a (greased) pie dish and bake for 20 minutes at 450 degrees.

Then add your leftovers on top of the dough.

Bake everything together for another 15 to 20 minutes or until firm in the middle.

It should resemble an omelet.

Use them for ravioli

Making your leftovers into a ravioli is another creative way to enjoy this delicious fall staple.

Just add parmesan cheese, egg yolks, salt, pepper, fresh thyme or parsley, and flour to the leftover sweet potatoes.

Mix everything together and then roll out the dough into thin sheets, about 1/8 inch thick.

Use a large circle cookie cutter or cup to create circles in the dough.

Then add a spoonful of the leftover in the middle and fold each round in half, sealing it closed with water on all sides.

Boil the ravioli for 10 minutes and enjoy.

Make a sweet potato pizza crust

Another way to use your leftovers is as a pizza crust.

You’ll need 1 cup of mashed sweet potatoes, 1/4 cup almond flour, 1 egg, 2 Tbsp melted butter or olive oil, and sea salt for the crust.

Mix all the ingredients together in a bowl and bake the crust for 15 minutes at 450 degrees.

Then add your favorite pizza toppings to it- marinara sauce, cheese, sausage, pepperoni, etc.

Cook everything another 10 to 15 minutes or until the cheese has melted and is starting to brown.

Add them to a breakfast omelet or scramble

Another easy way to use up your excess foods is to add them to an omelet or scramble.

Just chop up some garlic, green onions, and yellow onion.

Saute these in olive oil for 5 minutes until they are turning translucent.

Then add the cooked sweet potatoes and heat everything together for another 5 minutes on medium-high.

If your omelet isn’t sticking together well, add a tablespoon of water and cover for another minute or two to let the steam do its thing.

How long do cooked mashed sweet potatoes last in the fridge?

Are mashed sweet potatoes healthy?

One cup of cooked mashed sweet potatoes contains just 100 calories and is a complete source of protein, meaning it has all nine essential amino acids our bodies need but cannot produce on its own.

It also contains about 20% of your DV for calcium, 25% for vitamin A, and 7% for iron.

The only thing that makes this healthy food unhealthy is its high glycemic load; one cup carries a score of 42 on the GI index, meaning it causes a relatively large spike in blood sugar levels.

Can you save mashed sweet potatoes?

Yes, they can be saved.

In fact, they continue to ferment as long as they are stored in a container with no air inside it.

Make sure to use an airtight container of some kind and then transfer them into the fridge. (source)

Can I reheat mashed sweet potatoes?

Yes, you can reheat them and they will taste just as good.

One of the best ways to do this is by putting them in a waffle iron and cooking it until they’re crispy again.

Another option is to add them to a pan with some oil and saute them for about 10 minutes.

How can you tell if mashed sweet potatoes are bad?

If you leave them out at room temperature for too long, they will become slimy and gross.

In fact, as soon as they start to ferment, their taste changes drastically and it’s something many people describe as “sour.”

Because of this sour taste, fermentation is a fairly reliable way to tell if your leftovers have gone bad.

If you still aren’t sure, look at the color of the mashed potatoes.

If they are grey or green in color, that could also be a sign that harmful bacteria have started to grow in the food and could make you sick.

Additionally, if the leftovers have developed mold on them, just throw both the sweet potatoes and the mold away.

Mold is very dangerous for your health, even in small doses, so don’t take any chances with it. (source)

Can you freeze mashed sweet potatoes?

Yes, you can freeze them.

In fact, they actually taste pretty good after being frozen and then heated up again later on.

You can boil or steam them before freezing them for a softer texture that makes it easier to eat them when they’re thawed out.

To do this, just cook the potatoes as usual and then put them in an airtight container or freezer bag.

Make sure to leave about an inch of space for expansion and then stick them in the freezer.

Why are my mashed sweet potatoes watery?

They are only watery if they’ve been cooked for too long.

As soon as the natural starches in them start to break down, they will release excess liquid into the rest of the food.

This is why so many people find that overcooked sweet potatoes have a gushy or mushy texture and taste a bit off.


There are many delicious ways to enjoy your leftover mashed sweet potatoes.

You can turn them into muffins, pies, ravioli, or even a pizza crust.

Or, add them to an omelet or scramble for a quick and easy breakfast.

No matter how you choose to eat them, these recipes are sure to please.

So get cooking and enjoy your delicious fall staple in a whole new way.
