🍠What are purple sweet potatoes
Purple sweet potatoes are a type of sweet potato often called yams. There are a few varieties: Okinawan sweet potatoes (come from Japan) and Stokes (grown in the US). They have dark grayish-purple skin and a bright purple flash. Purple yams have a creamy texture and a sweet taste, just like regular sweet potatoes.
I usually find these potatoes at Whole Foods, Trader Joe's, Sprouts, or farmers' markets during the fall and winter months.
The purple version of a sweet potato is highly nutritious: high in antioxidants (anthocyanins and Vitamin C), dietary fiber, and potassium. Purple potatoes have a low glycemic index, meaning they will not spike the insulin levels as other types of carbohydrates.
These potatoes make a great side dish when baked, roasted, and mashed. The bright purple color will catch the eye of your family and guests.

📋Ingredients notes and substitutions
- Purple sweet potatoes - if you are in the United States, you will probably get the Stokes variety. Pick large potatoes, because it is easier to peel them.
- Ghee butter - will be used to fry the sage leaves and some for the potatoes. You can use regular butter or oil. Ghee gives a dish a unique flavor. It has a high smoking point, making it much healthier than other oils and butter. For a vegan dish, use vegan butter or olive oil.
- Sage leaves - this is optional, but crispy sage will balance the sweetness and create a holiday look. If you prefer this dish sweet, add a sweetener of your choice such as honey, maple syrup, or agave. Garlic powder, black pepper, and coriander are great for a savory side dish, while cinnamon, nutmeg, and cardamom are perfect for a sweet version.
- Salt - a little bit of sea salt for taste. Purple yams do not need much salt, compare to regular potatoes.
🔪Do I need to peel purple sweet potatoes
No, the skin is nutritious and can create an extra layer of texture for the dish. So, it is up to your liking to peel or not. I prefer peeling when making a puree. Also, if your potatoes are not organic, I suggest removing the skin.
Another important note, if you are keeping the skin make sure to scrub and rinse the yams extra well to void sand and dirt in your dish, and do not forget to remove any label stickers.
⏲️How to make purple sweet potato puree
- Peel - wash and scrub potatoes well under cold water. Using a veggie peeler, remove the skin of the potatoes.
- Cut - It doesn't matter how you cut the potatoes, they will be boiled and mashed anyway. I usually slice them into 1-2 inch circles and then cut them in half or quarter. The smaller pieces, the faster they will be cooked.
- Boil - add cut potato chunks into a large pot. Pour water enough to cover the potatoes. Bring to boil and simmer on medium-low heat for about 20 minutes or until the potatoes are fork tender.
- Fry sage - In a stainless steel skillet, heat 2 Tablespoons of ghee butter over medium heat. Add sage leaves and cook them on medium-high heat for 2 minutes on each side until they become crispy. Sprinkle a pinch of salt over the cooked sage leaves.
- Mash - now, drain the water reserving about ½ cup. Use a potato masher to puree cooked yams until they are one consistency. If the potatoes are too dry, add some of the reserved water for a creamier consistency.
- Season - remove the sage leaves and add the sage ghee butter to the mashed potatoes. Add salt. Mix everything well to combine.
- Serve - serve hot as a side dish with a few crispy sage leaves on top.
- pick larger potatoes when possible.
- reserve some water after boiling in case you need to thin the puree out in the process of meshing.
- use an electric hand mixer or potato ricer for extra fluffy potatoes
- do not add too much salt.
Serve this healthy side dish in place of regular mashed potatoes. Sweet potatoes go well with chicken, turkey, or pork. The vibrant purple color, creaminess, and sweet and savory taste make this purple potato recipe a perfect Thanksgiving side dish.
It goes well with pinto, and black beans for a meatless meal.
Serve the leftovers for breakfast with some eggs. Good quality carbs will give you energy and will keep you full until lunch.
🌡️How to store and reheat
Sweet potato mash makes great leftovers that taste great the next day compared to white potatoes.
Transfer purple potato leftovers to an airtight container and store them in the fridge for no longer than 3 days.
Reheat in the microwave, covered for about 1 minute or until hot. You may want to add some extra butter after reheating.
