What are Purple Sweet Potatoes?
Two different varieties of purple sweet potatoes are commonly available in the US. The Stokes sweet potato and the Japanese sweet potato.
The Stokes sweet potato is a bit more starchy and less sweet than orange sweet potatoes, while the Japanese variety is more similar in texture to the traditional variety of sweet potato.
You're unlikely to find these sweet potatoes in your regular grocery store but are often carried in Asian markets or large specialty grocery store chains such as Whole Foods.
Are you looking to make a few swaps? Here are some we discovered during recipe testing that we recommend.
- Butter: You can swap the butter and use ghee instead for a similar flavor. Other options include olive oil or coconut oil. These oils are great for adding some fat to the mixture but do affect the flavor since they lack the rich dairy flavor of butter.
- Milk: You can use a dairy-free alternative such as coconut milk or another plant milk. Just be sure to opt for milk that is unsweetened and doesn't contain other flavors.
- Purple sweet potatoes: If you can't find them this recipe also works with orange sweet potatoes. The results will taste similar but you won't end up with the same brilliant color.
If you're looking to change things up completely, mashed sweet potatoes can be prepared in a variety of tasty and unique ways.
- Dairy-free or vegan: Swap the butter for coconut oil or oil and use coconut milk in place of the dairy milk.
- Add some roasted garlic. Mash roasted garlic cloves into the for delicious, mellow garlic flavor.
- Make them spicy. Add some chili powder, cumin, and cayenne pepper for flavorful and unique sweet potatoes.
- Cinnamon and nutmeg: A classic combination that's perfect for the holidays!
- Purple potatoes: This same recipe works with regular purple potatoes. Their color is a bit different and they taste more similar to regular potatoes.
How to Make Mashed Purple Sweet Potatoes
Making creamy purple mashed sweet potatoes doesn't require a lot of work! Here's an overview of the steps.
- First, start with rinsing, peeling, and cutting the sweet potatoes into cubes. Place them in a large pot.
PRO TIP: Aim for evenly sized cubes so that the potatoes cook in the same amount of time.
- Add enough cold water to cover the potatoes and add salt to the pot. The key to flavorful mashed potatoes is cooking the potatoes in salted water so that it infused the potatoes with flavor as they cook.
- Place the pot on the stove and heat until boiling. Cook the potatoes for about minutes or until they feel tender when pricked with a fork.
- Drain the potatoes very well and return them to the pan or place them in a mixing bowl.
- Add the butter, salt, and pepper to the pot with the potatoes.
- Mash the purple sweet potatoes using a potato masher, fork, or electric mixer on low speed until the potatoes are mashed to your desired consistency.
- Mix in a quarter cup of milk to the potatoes. Add more until you are happy with the consistency of the mashed sweet potatoes.
- Transfer the purple mashed potatoes to a serving dish and top with additional butter, salt, pepper, and chopped parsley.
Hint: I find using an electric hand mixer the easiest way to mash potatoes. It's both quicker and requires less effort!
Store leftover purple mash in the fridge for up to five days. To reheat, return them to a saucepan and heat over low until they are warmed through. You can also add a bit of liquid if they seem too thick after sitting.
I do not recommend freezing leftovers.
