Ingredients
Be sure to buy purple-fleshed sweet potatoes like Stokes purple sweet potatoes and not a Japanese purple sweet potato with white flesh. Estimate a half sweet potato per person, depending on the size of your sweet potato, the size of your person, and whether this is a Thanksgiving potluck or what else is being served.

What’s the difference between purple sweet potato and purple yams?
Tip from the wise quacker: people commonly confuse sweet potatoes and yams. You can find a rainbow of sweet potatoes in white, orange, yellow, and purple. But most everything we get in the U.S. is a sweet potato, not a yam.
Well, that used be true. Because ube, a purple yam, is starting to appear more commonly here in ube crinkle cookies and other ube baked goods, we are starting to see true yams in the U.S.

Variations and substitutions
- Use a sweet potato of a different color. Purple sweet potatoes are a bit drier than other sweet potatoes, but they won’t taste any different.
- Add a parsnip or a bit of cinnamon and nutmeg for a touch of spice.
- Add some brown sugar and cover in marshmallows for a non-traditional Thanksgiving mashed sweet potato casserole!
Recipe tips and tricks
I’ve been making mashed sweet potatoes with banana like this for years. I love how the recipe is so easy to make and the banana adds sweetness and creaminess so you don’t need to add butter or milk unless you want to!
How to bake purple sweet potatoes
Step 1: Roast the sweet potatoes in your oven at 425 degrees or so. Poke a few holes in the skin and then wrap them in foil.
They’re done when you can easily pierce the skin and flesh with a fork or knife. Let the baked purple sweet potatoes cool a few minutes until you can handle them.
You don’t have to peel your mashed potatoes if you don’t mind the skin. In fact, sweet potato skins provide a lot of nutrition!
Mashing the purple sweet potatoes
Step 2: Put the baked purple sweet potatoes in a bowl with the banana and salt. Mash with a potato masher and serve immediately.
What to serve with mashed sweet potatoes
- Serve as a simple side to complement a simple roast meat dish like cast iron chicken breasts or pork tenderloin with bourbon apples minus the apples.
- Make a meatloaf! Try these mashed sweet potatoes with a Thanksgiving turkey meatloaf or taco meatloaf.
- Use this as a filling in mini pie crust shells for savory mini tarts.
Recipe FAQs
Absolutely. The sweet potatoes and banana make these so rich and creamy, even when dairy-free. You could add a vegan butter or any non-dairy milk of your choice to make them creamier. Or you could leave both out.
If you’re like me and have a thing for lavender cookies, and Empress gin cocktails, and purple sweet potatoes, you’ve probably noticed that purple vegetables usually change color when you cook them. That’s due to the breakdown of the anthocyanins. After a few disappointing adventures in color with somewhat purple latkes and my reddish velvet beet waffles, I was so ecstatic to see the color of this sweet potato and banana mash!
Yes. Sweet potatoes can be frozen either after cooking or after mashing and stored for months. The texture won’t be the same, but they’ll still taste good.
