I guess I’m really into the color purple right now, hence my post on Purple Carrot Hummus right before this new recipe. With so much gray weather during the Minnesota winter, it can’t hurt to brighten up your plate every once in a while!
I picked up a bag of purple potatoes a few weeks ago so that I could use them for a recipe, but I didn’t realize how much fun I would have photographing the finished product. Isn’t the color of mashed purple potatoes just gorgeous?!
In addition to the vibrant hue, this recipe is SUPER simple to make. The technique is really not any different than other mashed potato recipes. The main difference is that purple potatoes have some extra benefits, which I’ll explain now.
Purple Potato Nutrition
The deep color of purple potatoes is a sign that they contain anthocyanins, or pigments that act as antioxidants. In the body, antioxidants help protect against free radical damage that contributes to the development of heart disease, diabetes, and some cancers.
Interestingly, the antioxidant activity of purple potatoes is two to three times higher than that of white potatoes! Eating purple potatoes may also help reduce blood pressure and have less of an effect on raising blood sugar compared to other types of potatoes. Not bad for a spud, huh?
Where to Buy Purple Potatoes
You can usually find purple potatoes at most grocery stores, including local chains and Whole Foods. If a store doesn’t carry loose purple potatoes, check to see if they sell them as part of a bagged potato medley.
For my mashed purple potatoes, I used a variety known as Magic Molly potatoes, which I found to have an earthier taste than white or yellow potatoes. There are several other varieties that have a purple color, including purple sweet potatoes.
How Long to Boil Mashed Purple Potatoes
As I mentioned, this recipe is not at all complicated and is prepared in the same way as other types of mashed potatoes. So, of course, you need to boil your purple potatoes first! Boil them for 15 to 17 minutes until fork-tender.
- Whether or not you peel purple potatoes before boiling is up to you. Some people prefer to have pieces of skin for added texture and fiber in the finished recipe, while others do not. Just make sure you scrub off or wash away any dirt from the skin if you choose not to peel them.
- The potatoes will lose some of their color in the water while boiling, but this is totally normal. Mashed purple potatoes are still gorgeous even with the slight color loss!
- Since purple potatoes are earthier than most other varieties, you may find that you’ll need a little extra salt, butter, or herbs to get to your desired flavor. For additional flavor, add up to 1/2 cup sour cream and/or fresh herbs, like chives or parsley.
- This recipe tastes delicious as a side for a piece of fish or meat or as the base of a stew or gravy. Leftovers will keep in an airtight container in the fridge for 2 to 3 days. Reheat in the microwave, adding a splash of milk or a slab of butter as needed, for 1 to 2 minutes until heated through.

Mashed Purple Potatoes
- Prepare the potatoes by peeling them if desired (you can also leave the peels on), removing any bruised areas, and cutting them into 2-inch pieces. Place them in a large pot, cover with water, add up to 1/2 tsp of salt, and bring to a boil. Let them boil for 15 to 17 minutes until fork-tender.
- In the meantime, combine the milk and butter in a small saucepan over low heat. Cook until the butter is melted, then remove from heat, being careful not to let the mixture boil.
- When the potatoes are cooked, drain and return them to the pot. Pour in the milk and butter mixture, and mash the potatoes with a handheld masher or a handheld electric mixer (for a creamier texture) until smooth. Taste, and add salt, pepper, more butter, and fresh herbs as desired. For additional flavor, consider adding up to 1/2 cup sour cream. Enjoy warm!
- Serve on the side of meat or fish or as the base for a gravy or stew.
- Leftovers will last in an airtight container in the fridge for 2 to 3 days. Reheat in the microwave for 1 to 2 minutes. You may need to add a splash or milk or some melted butter and stir before microwaving to prevent drying out the potatoes.
- Purple potatoes are earthier than other varieties, so you may need to add more butter, salt, pepper, or herbs to reach your desired flavor. The nutrition facts listed here do not take into consideration added salt or other fix-ins.
