The white-fleshed sweet potato (boniato) is as versatile as traditional American potatoes. In the Caribbean, there is a huge variety of sweet potatoes and people are always finding different ways to use them. Often, they are substituted for regular potatoes.

In an effort to serve a different kind of mashed potato dish, the white-flesh sweet potatoes were used to make this spiced mashed potato dish. Made with the addition of green onions and chili pepper to give it a little kick, serve this dish just as you would regular mashed potatoes. It should go great with pork, chicken, and other protein main courses.

The boniato is native to the Americas, and its name means "harmless" in Spanish, probably to distinguish it from poisonous plants. It grows year-round in the Caribbean. It has purple skin and white flesh that isn't as sweet as other varieties of sweet potatoes. It is high in vitamins A and C and in fiber, making it hearty and healthy.

There are also many varieties of spicy chili peppers native to the Caribbean; including the Scotch bonnet, Caribbean red peppers, and Trinidad scorpion peppers, that make the hottest of the hotlists. You can add milder chili pepper, of course, and adjust the amount to taste, or leave it out if you wish.

"The mashed white sweet potatoes were savory, yet with a hint of sweetness, and the green onions and chili pepper were excellent additions. These would be a tasty change of pace for a holiday meal, or serve them as a side to go with meat, poultry, fish, or a plant-based protein." — Diana Rattray

Tips

  • Your mashed white sweet potatoes can be part of a Caribbean feast or family dinner. A baked or roasted chicken breast with Caribbean jerk seasoning would be a good accompaniment, as would pork chops.
  • Besides enjoying them again as mashed potatoes, you can use them in a variety of ways. Top a shepherd's pie made with meat, vegetables, or lentils with the leftovers. You can also form them into potato patties adding vegetables, flour, and egg (or egg replacer), and fry them to make a great breakfast dish or appetizer to serve with dip or chutney.

Recipe Variations

  • For vegan mashed white sweet potatoes, use a milk alternative or broth, and replace the butter with vegan-friendly margarine.
  • To make the sweet potatoes richer, use half-and-half or light cream instead of milk.
  • To reduce the heat, replace the hot chili pepper with a few tablespoons of minced red bell pepper.



How to Store & Freeze

  • Refrigerate leftover mashed sweet potatoes in an airtight container and eat within 4 days.
  • To freeze cooked mashed sweet potatoes, transfer them to an airtight container or zip-close freezer bag. Label the container with the name and date and freeze for up to 12 months.
